Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION AND DESCRIPTION OF BUSINESS	ORGANIZATION AND DESCRIPTION OF BUSINESS Yelp Inc. was incorporated in Delaware on September 3, 2004. Except where specifically noted or the context otherwise requires, the use of terms such as the “Company” and “Yelp” in these Notes to Consolidated Financial Statements refers to Yelp Inc. and its subsidiaries. Yelp is a trusted local resource for consumers and a partner in success for businesses of all sizes. Consumers trust Yelp for its extensive ratings and reviews of businesses across a broad range of categories, while businesses advertise on Yelp to reach its large audience of purchase-oriented and generally affluent consumers. Yelp has operations in the United States, United Kingdom, Canada, Ireland and Germany. Basis of Presentation —The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). All intercompany balances and transactions have been eliminated upon consolidation. Certain reclassifications have been made to the consolidated financial statements of prior periods and the accompanying notes to conform to the current period presentation. Certain Significant Risks and Uncertainties —The Company operates in a dynamic industry and, accordingly, may be affected by a variety of factors. For example, the Company’s management believes that changes in any of the following areas could have a significant negative impact on the Company in terms of its future financial position, results of operations or cash flows: adverse macroeconomic conditions, such as the ongoing impact of the COVID-19 pandemic; the Company’s ability to maintain and expand its advertiser base; the success of the Company's strategy; qualified employees and key personnel; levels of user engagement on the Company's platform; industry competition; reliance on search engines and application marketplaces; the quality and reliability of reviews; real or perceived security breaches and the Company's ability to maintain uninterrupted operation of its network infrastructure; protection of the Company’s brand, reputation and intellectual property; intellectual property infringement and other disputes; and changes in government regulation affecting the Company’s business, among other things.

SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
	Dec. 31, 2022
Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Use of Estimates —The preparation of the Company’s consolidated financial statements in conformity with GAAP requires management to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of income and expenses during the reporting period. Items that require estimates, judgments or assumptions include, but are not limited to, determining variable consideration and identifying the nature and timing of satisfaction of performance obligations, allowance for doubtful accounts and credit losses, fair value and estimated useful lives of long- and indefinite-lived assets, litigation loss contingencies, liabilities related to incurred but not reported insurance claims, fair value and achievement of targets for performance-based restricted stock units (“PRSUs”) and income taxes. These estimates, judgments and assumptions are based on information available as of the date of the consolidated financial statements; therefore, actual results could differ from management’s estimates due to macroeconomic uncertainty and other factors. Foreign Currency Translation —The consolidated financial statements of the Company’s foreign subsidiaries are measured using the local currency as the functional currency. Assets and liabilities of foreign subsidiaries are translated at exchange rates in effect as of the balance sheet date. Revenues and expenses are translated at average exchange rates in effect during the year. Translation adjustments are recorded within accumulated other comprehensive loss, a separate component of stockholders’ equity. Cash and Cash Equivalents —The Company considers all highly liquid investments, such as treasury bills, commercial paper, certificates of deposit and money market instruments with maturities of three months or less at the time of acquisition to be cash equivalents. Cash and cash equivalents primarily consist of amounts held in interest-bearing money market funds that were readily convertible to cash. The fair value of cash and cash equivalents approximates their carrying value. Marketable Securities —The Company considers highly liquid treasury notes, U.S. agency securities, corporate debt securities, money market funds and other funds with maturities of more than three months to be marketable securities. These securities are classified as short-term marketable securities on the consolidated balance sheets as they represent the investment of cash available for current operations. The Company has a policy that generally requires its securities to be investment grade (i.e., rated ‘A’ or higher by bond rating firms) with the objective of minimizing the potential risk of principal loss. The Company classifies its marketable securities as available-for-sale and determines the classification at the time of purchase based on its investment strategy; it reevaluates such designation at each balance sheet date. Available-for-sale securities are stated at fair value as of each balance sheet date and are periodically assessed for impairment. An investment is impaired if the fair value of the investment is less than its amortized cost basis. The Company reviews the securities in an unrealized loss position and evaluates whether credit loss exists by considering factors such as historical experience, market data, issuer-specific factors including their credit rating, and current economic conditions. If a credit loss exists, the Company measures the loss by comparing the present value of cash flows expected to be collected from the security with the amortized cost basis of the security. An allowance for credit loss is recorded as a component of other income (expense), net, limited by the amount of unrealized loss. Any remaining unrealized losses are recorded to other comprehensive income (loss). The Company determines any realized gains or losses on the sale of marketable securities on a specific identification method and records such gains and losses as a component of other income (expense), net. Amortization of premiums and accretion of discounts are included in interest income. If the Company has the intent to sell an available-for-sale security in an unrealized loss position or it is more likely than not that it will be required to sell the security prior to recovery of its amortized cost basis, any previously recorded allowance is reversed and the entire difference between the amortized cost basis of the security and its fair value is recognized in the consolidated statements of operations. Concentrations of Credit Risk —Financial instruments that potentially subject the Company to concentration of credit risk consist primarily of cash and cash equivalents, marketable securities and other investments, and accounts receivable. The Company places its cash and cash equivalents, marketable securities and other investments with major financial institutions, which management assesses to be of high credit quality, in order to limit the exposure of each investment. Credit risk with respect to accounts receivable is dispersed due to the Company’s large number of customers. In addition, the Company’s credit risk is mitigated by the relatively short collection period. Collateral is not required for accounts receivable. Accounts Receivable, Net, and Payment Terms —The timing of revenue recognition may differ from the timing of invoicing to customers. The Company records an accounts receivable balance when revenue is recognized prior to or at the time of invoicing the customer. Payment terms and conditions vary by contract type and the service being provided. For advertising services, the Company typically invoices customers on a monthly basis, one month in arrears, with payment due either at the end of each billing period or up to 30 days after the end of the billing period. For transaction services, the Company collects its commission fee on each transaction either at the time of the transaction or up to 30 days after the end of the billing period. For subscription services, the Company typically invoices customers one month in advance, with payment due at the beginning of each billing period. Allowance for Doubtful Accounts —The Company maintains an allowance for doubtful accounts receivable. The allowance reflects the Company's best estimate of probable losses associated with the accounts receivable balance. It is based upon historical experience and loss patterns, the number of days that billings are past due, an evaluation of the potential risk of loss associated with delinquent accounts based on the credit risk of those accounts, known delinquent accounts, as well as current conditions and reasonable and supportable economic forecasts. When new information becomes available that allows the Company to more accurately estimate the allowance, it makes an adjustment, which is considered a change in accounting estimate. The carrying value of accounts receivable approximates their fair value. Deferred Contract Costs —The Company has determined that certain sales incentive compensation costs are incremental costs to obtain the related contract. These costs are capitalized in the period in which they are incurred and amortized on a straight-line basis over the expected customer life of the associated contract. The Company uses a straight-line basis as it expects the benefit of these costs to be realized uniformly over the amortization period. The amortization periods for contract costs, which extend up to 32 months, were determined based on both qualitative and quantitative factors, including product life cycle attributes and customer retention historical data. For contract costs with amortization periods of less than 12 months, the Company applies a practical expedient to expense such costs as incurred. The Company assesses deferred contract costs for impairment on a quarterly basis. No impairment charges were recorded in the periods presented. Amortized contract costs are recorded within sales and marketing expense in the consolidated statements of operations. Deferred contract costs are included within other non-current assets on the Company’s consolidated balance sheets (see Note 10, “ Other Non-Current Assets ”). Deferred Revenue —The Company records deferred revenue when it has received consideration, or has the right to receive consideration, in advance of the transfer of the performance obligations of the contract to the customer. Property, Equipment and Software —Property, equipment and software are stated at cost less accumulated depreciation and amortization. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, which are approximately three Website and Internal-Use Software Development Costs —Costs related to website and internal-use software are primarily related to the Company’s website and mobile app, including support systems. The Company capitalizes its costs to develop software when: preliminary development efforts are successfully completed; management has authorized and committed project funding; and it is probable that the project will be completed and the software will be used as intended. Costs incurred for enhancements that are expected to result in additional material functionality are capitalized and amortized over the estimated useful life of the upgrades. Such costs are amortized on a straight-line basis over the estimated useful life of the related asset, which is generally three years. The Company capitalizes certain implementation costs incurred related to cloud computing arrangements that are service contracts. Such costs are amortized on a straight-line basis over the term of the associated hosting arrangement plus any reasonably certain renewal period. Any capitalized amounts related to such arrangements are recorded within prepaid expense and other current assets and within non-current assets on the consolidated balance sheets. Leases —The Company leases its office facilities under operating lease agreements that expire from 2023 to 2031, some of which include options to renew at the Company’s sole discretion. If exercised, such options would extend the lease terms by up to ten years. Additionally, certain lease agreements contain options to terminate the leases, which require 6 to 12 months prior written notice to the landlord. The Company does not have any finance lease agreements. The Company determines if an arrangement contains a lease at inception. The Company recognizes on its consolidated balance sheets operating lease liabilities representing the present value of future lease payments, and an associated operating lease right-of-use asset for any operating lease with a term greater than one year. The Company recognizes the amortization of the right-of-use asset each month within lease expense. The Company elected to use the practical expedient for short-term leases, and therefore does not record operating lease right-of-use assets or lease liabilities associated with leases with durations of 12 months or less. When recording the present value of lease liabilities, a discount rate is required. The Company has concluded that the rates implicit in the various operating lease agreements are not readily determinable. As a result, the Company instead uses its incremental borrowing rate, which is calculated based on hypothetical borrowings to fund each respective lease over the lease term, as of the lease commencement date, assuming that borrowings are secured by the various leased properties. The incremental borrowing rates are determined based on an assessment of the Company’s implied credit rating, using ratings scales from reputable rating agencies that consider a number of qualitative and quantitative factors. Market rates are derived as of the lease commencement dates with reference to companies with the same debt rating that operate in a similar industry to the Company. The Company does not recognize its renewal options as part of its right-of-use assets and lease liabilities until it is reasonably certain that it will exercise such renewal options. The Company does not combine lease and non-lease components; its lease agreements provide specific allocations of the Company’s obligations between lease and non-lease components. As a result, the Company is not required to exercise any judgment in determining such allocations. The Company has subleased certain office facilities under operating lease agreements that expire in 2025. The sublease agreements do not contain any options to renew. The Company recognizes a majority of the sublease rental income as a reduction in rent expense on a straight-line basis over the lease period, with any sublease income in excess of the original lease cost recorded to other income, net. Goodwill —Goodwill represents the excess of the purchase price in a business combination over the fair value of net tangible and intangible assets acquired. The carrying amount of goodwill is reviewed at least annually, or more frequently if events or changes in circumstances indicate that the carrying value of goodwill may not be recoverable. The Company has the option to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the Company determines that it is more likely than not that its fair value is less than the carrying amount, or opts not to perform a qualitative assessment, then the Company will compare the fair value of a reporting unit with its carrying amount and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. No impairment charges associated with goodwill have been recorded by the Company to date. Intangible Assets —Intangible assets include acquired intangible assets identified through business combinations, which are carried at fair value less accumulated amortization, and purchased intangible assets, which are carried at cost less accumulated amortization. Amortization is recorded over the estimated useful lives of the assets, generally two years to 12 years. The Company reviews amortizable intangible assets to be held and used for impairment whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable. Determination of recoverability is based on the lowest level of identifiable estimated undiscounted cash flows resulting from the use of the asset and its eventual disposition. Measurement of any impairment loss is based on the excess of the carrying value of the asset over its fair value. No material impairment charges have been recorded to date. Impairment of Long-Lived Assets and Long-Lived Assets to Be Disposed of —The Company evaluates its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell. Stock Repurchases —The Company accounts for repurchases of its common stock by recording the cost to repurchase those shares to treasury stock, a separate component of stockholders’ equity. Upon retirement, the carrying amount of treasury stock is reduced with a corresponding reduction to par value of common stock, with any excess of the cost incurred to repurchase shares over their par value recorded as an adjustment to retained earnings (accumulated deficit) on the date of retirement. Revenue Recognition —The Company generates revenue from the sale of advertising products, transactions with consumers and other revenue sources, which correspond to the Company’s major product lines. The Company recognizes revenue by applying the following steps: the contract with the customer is identified; the performance obligations in the contract are identified; the transaction price is determined; the transaction price is allocated to the performance obligations in the contract; and revenue is recognized when (or as) the Company satisfies these performance obligations in an amount that reflects the consideration it expects to be entitled to in exchange for those services. The Company applies the portfolio practical expedient to account for the vast majority of contracts with customers in each category of revenue. The Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which the amount of revenue it recognizes is equal to the amount which the Company has a right to invoice. Contracts with customers can include multiple performance obligations, where the transaction price is allocated to each performance obligation based on its relative standalone selling price (“SSP”). The Company determines SSP based on the prices of the promised goods or services charged when sold separately to customers, which are determined using contractually stated prices. The Company allocates revenue to each of the performance obligations included in a contract with multiple performance obligations at the inception of the contract. The various products and services comprising contracts with multiple performance obligations are typically capable of being both distinct and distinct within the context of the arrangement and are accounted for as separate performance obligations. For all contracts with customers, estimates and assumptions include determining variable consideration and identifying the nature and timing of satisfaction of performance obligations. The Company may accept lower consideration than the amount promised per the contract for certain revenue transactions and certain customers may receive cash based incentives, credits or refunds, which are accounted for as variable consideration when estimating the amount of revenue to recognize. The Company estimates these amounts based on the expected amount to be provided to customers and constrains the revenue. The Company believes that there will not be a significant reversal in the amount of cumulative revenue recognized when the uncertainty associated with the estimates of variable consideration is subsequently resolved. For contracts satisfied over time, the Company applies the invoice practical expedient to depict the value transferred to the customer and measure of progress towards completion of its obligations. The Company considers the right to receive consideration from a customer to correspond directly with the value to the customer of its performance completed to date. The Company does not consider the effects of the time value of money as substantially all of the Company’s contracts are invoiced on a monthly basis, one month in arrears. Revenue is recognized net of any taxes collected from customers, which are remitted to governmental authorities. The Company does not typically refund customers for services once it determines the performance obligations of the contract have been satisfied, but will assess any refund requests from customers and partners on a case by case basis. The Company records an allowance for potential future refunds, which is estimated based on historical trends and recorded as a reduction of net revenue. Advertising . The Company generates advertising revenue primarily through the display of advertising products on its website and mobile app. These arrangements are evidenced by either written or electronic acceptance of a contract that stipulates the types of advertising to be delivered, the timing and pricing. Performance-based advertising placements are priced on a cost-per-click basis, while impression-based advertising placements are priced on a cost per thousand impressions basis. The Company recognizes revenue from the delivery of performance-based ads and impression-based ads in the period of delivery, in each case net of customer discounts. The Company also offers businesses premium features in connection with their business pages pursuant to fixed monthly fees, and recognizes revenue from such offerings over the service period. The Company also generates advertising revenue through indirect sales of advertising products, such as through reseller contracts that allow partners to sell Yelp Branded Profiles to their clients and the monetization of remnant advertising inventory through third-party ad networks, and recognizes revenue in the period of delivery. Transactions . The Company generates transactions revenue primarily from revenue-sharing partner contracts. The Company’s transactions platform provides consumers with the ability to place food orders for pickup and delivery through third parties, primarily Grubhub, or complete other transactions directly on Yelp. The Company earns a per-transaction commission fee pursuant to partnership contracts for acting as an agent for these transactions, which it recognizes on a net basis and includes in revenue upon completion of a transaction. Other Revenue . The Company generates other revenue through subscription services contracts, such as sales of monthly subscriptions to Yelp Guest Manager, licensing contracts for access to Yelp data, and other non-advertising, non-transaction partnerships. Subscription revenues are recognized ratably over the contract terms beginning on the commencement date of each contract, which is the date the service is made available to customers. Cost of Revenue —The Company’s cost of revenue primarily consists of credit card processing fees, website infrastructure expense, which includes website hosting costs, and salaries, benefits and stock-based compensation expense for the infrastructure teams responsible for operating the Company’s website and mobile app, and excludes depreciation and amortization expense. Cost of revenue also includes third-party advertising fulfillment costs. Research and Development —The Company incurs research and development expenses for costs it incurs in research aimed at developing, and in translating the results of such research into, new products and services or significant improvements to existing products or services intended for internal use. Such costs are considered research and development and are expensed as incurred. These expenses primarily consist of employee-related costs (including stock-based compensation) for the Company’s engineers and other employees engaged in the research and development of its products and services, as well as allocated indirect overhead costs. Research and development costs were $294.5 million, $265.2 million and $230.1 million for the years ended December 31, 2022, 2021 and 2020, respectively, and are recorded to costs and expenses in the consolidated statements of operations for those periods, primarily within product development costs. Stock-Based Compensation —The Company accounts for stock-based employee compensation plans under the fair value recognition and measurement provisions, which require all stock-based payments to employees, including grants of stock options, restricted stock awards, restricted stock units (“RSUs”), PRSUs and issuances under its 2012 Employee Stock Purchase Plan, as amended (“ESPP”), to be measured based on the grant-date fair value of the awards. The Company accounts for forfeitures as they occur. The Company estimates the fair value of options granted to employees on the grant date using the Black-Scholes-Merton option valuation model. This valuation model for stock-based compensation expense requires the Company to make assumptions and judgments about the variables used in the calculation, including the expected term (weighted-average period of time that the options granted are expected to be outstanding), the expected volatility in the fair market value of the Company’s common stock, a risk-free interest rate and expected dividends. No compensation cost is recorded for options that do not vest. The Company uses the simplified calculation of expected life as it does not have sufficient appropriate historical exercise data on which to base its own estimate. Expected volatility is based on an average of the historical volatilities of the common stock of several entities with characteristics similar to those of the Company. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for periods corresponding with the expected life of the option. The Company recognizes compensation cost related to options using the straight-line method. The fair value of RSUs is measured using the closing price of the Company’s common stock on the New York Stock Exchange on the grant date. The Company recognizes compensation cost related to RSUs using the straight-line method. No compensation cost is recorded for RSUs that do not vest. In May 2020, the Company changed its method of settling the employee tax liabilities associated with the vesting of RSUs from withholding a portion of the vested shares and covering such taxes with cash from its balance sheet (“Net Share Withholding”), to selling a portion of the vested shares to cover taxes. In November 2020, the Company reverted its method of settling these employee tax liabilities to Net Share Withholding. The Company has two types of PRSUs outstanding — awards for which the vesting is subject to both a time-based vesting schedule and either (a) a market condition or (b) the achievement of performance goals. For the awards subject to a market condition, the Company uses a Monte Carlo model to determine the fair value of the PRSUs. The Company recognizes compensation cost related to PRSUs using the accelerated method. Compensation costs are recorded if the service condition is met regardless of whether the market performance condition is satisfied. No compensation cost is recorded if the service condition is not met. For the awards subject to performance goals, compensation costs are recorded when the Company concludes that it is probable that the performance conditions will be achieved. The Company performs an analysis in each reporting period to determine the probability that the performance goals will be met, and recognizes a cumulative catch-up adjustment to compensation cost for changes in its probability assessment in subsequent reporting periods, if required, until the performance period has expired. The fair value of the PRSUs is measured using the closing price of the Company's common stock on the New York Stock Exchange on the grant date. The Company recognizes compensation cost related to PRSUs using the accelerated method. No compensation cost is recorded if the service condition is not met. Advertising Expenses —Advertising costs are expensed in the period in which the advertising takes place. Costs of producing advertising are expensed in the period in which production takes place. Total advertising expenses incurred were $71.1 million, $56.3 million and $22.2 million for the years ended December 31, 2022, 2021 and 2020, respectively. Comprehensive Income (Loss) —Comprehensive income (loss) consists of net income (loss) and other comprehensive income (loss), which consists of foreign currency adjustments and unrealized loss on available-for-sale debt securities, net of tax. Income Taxes —The Company records income taxes using the asset and liability method, which requires the recognition of deferred tax assets (“DTAs”) and liabilities for the expected future tax consequences of events that have been recognized in the Company’s financial statements or tax returns. In estimating future tax consequences, the Company generally considers all expected future events other than enactments or changes in the tax law or rates. In assessing the realization of deferred tax assets, the Company considers whether it is more likely than not that all or some portion of deferred tax assets will not be realized. The ultimate realization of the deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Valuation allowances are provided to reduce deferred tax assets to the amount that is more likely than not to be realized. In determining the need for a valuation allowance, the weight given to positive and negative evidence is commensurate with the extent to which the evidence may be objectively verified. The Company evaluates the ability to realize net deferred tax assets and the related valuation allowance on a quarterly basis. The Company operates in various tax jurisdictions and is subject to audit by various tax authorities. The Company provides for tax contingencies whenever it is deemed probable that a tax asset has been impaired or a tax liability has been incurred for events such as tax claims or changes in tax laws. Tax contingencies are based upon their technical merits, relative tax law and the specific facts and circumstances as of each reporting period. Changes in facts and circumstances could result in material changes to the amounts recorded for such tax contingencies. The Company recognizes a tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. Employee Benefit Plan —The Company sponsors a qualified 401(k) defined contribution plan covering eligible employees. Participants may contribute a portion of their annual compensation up to a maximum annual amount set by the Internal Revenue Service (“IRS”). Employer contributions under this plan were $8.7 million, $8.0 million and $6.1 million for the years ended December 31, 2022, 2021 and 2020, respectively. Insurance —The Company is self-insured for certain employee benefits including medical, dental and vision; however, the Company obtains third-party excess insurance coverage to limit its exposure to certain claims. Liabilities associated with these benefits include estimates of both claims filed and losses incurred but not yet reported. The Company utilizes valuations provided by reputable, independent third-party actuaries. The Company’s self-insured liabilities are included in the consolidated balance sheets within accounts payable and accrued liabilities.

As of December 31, 2021, the Company did not have any marketable securities and a majority of the Company's investments were in highly liquid money market funds. The contractual maturities for marketable securities classified as available-for-sale as of December 31, 2022 were as follows (in thousands): Amortized Cost Fair Value Due in one year or less $ 50,057 $ 49,969 Due in one to five years 47,362 46,799 Total $ 97,419 $ 96,768 In March 2020, the Company changed its investment strategy in response to uncertainties resulting from the COVID-19 pandemic to allow for more flexibility in preserving liquidity, which led to the transfer of $300.2 million of amortized cost of its investment portfolio from a held-to-maturity classification to available-for-sale. As a result of this transfer, in March 2020, the Company reversed the allowance for credit loss that had been previously recorded and measured the securities at fair value as of the transfer date by recording an immaterial allowance for credit loss to other income, net and the remaining adjustment as an immaterial unrealized loss recorded to other comprehensive income.

FAIR VALUE MEASUREMENTS

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS The Company’s cash equivalents are recorded at fair value in the consolidated balance sheets. Additionally, the Company carries its available-for-sale debt securities at fair value. See Note 4, “ Marketable Securities , ” for further details. The accounting guidance for fair value measurements prioritizes the inputs used in measuring fair value in the following hierarchy: Level 1 —Observable inputs, such as quoted prices in active markets, Level 2 —Inputs other than quoted prices in active markets that are observable either directly or indirectly, or Level 3 —Unobservable inputs in which there are little or no market data, which require the Company to develop its own assumptions. This hierarchy requires the Company to use observable market data, when available, to minimize the use of unobservable inputs when determining fair value. The Company’s money market funds are classified within Level 1 of the fair value hierarchy because they are valued using quoted prices in active markets. The Company’s certificates of deposit, commercial paper, corporate bonds, agency bonds and U.S. government bonds are classified within Level 2 of the fair value hierarchy because they have been valued using inputs other than quoted prices in active markets that are observable directly or indirectly. The following table represents the fair value of the Company’s financial instruments, including those measured at fair value on a recurring basis, as of December 31, 2022 and 2021 (in thousands): December 31, 2022 December 31, 2021 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Cash equivalents: Money market funds $ 247,551 $ — $ — $ 247,551 $ 390,376 $ — $ — $ 390,376 Commercial paper — 2,524 — 2,524 — — — — Marketable securities: Certificates of deposit — 10,651 — 10,651 — — — — Commercial paper — 13,054 — 13,054 — — — — Corporate bonds — 32,351 — 32,351 — — — — Agency bonds — 2,999 — 2,999 — — — — U.S. government bonds — 35,189 — 35,189 — — — — Other investments: Certificates of deposit — 10,000 — 10,000 — 10,000 — 10,000 Total cash equivalents, marketable securities and other investments $ 247,551 $ 106,768 $ — $ 354,319 $ 390,376 $ 10,000 $ — $ 400,376 The certificates of deposit that are categorized as other investments are reflected in prepaid expenses and other current assets on the consolidated balance sheets as of December 31, 2022 and 2021. Certain long- and indefinite-lived assets are recognized at fair value on a nonrecurring basis, including assets that are written down as a result of an impairment. The Company recognized an impairment charge related to right-of-use (“ROU”) assets and leasehold improvements associated with certain of its operating leases that it subleased during the years ended December 31, 2022 and 2021. See Note 9, “ Leases , ” for further details. The Company estimated the fair value of these assets as of the effective dates of the agreements using an income approach based on expected future cash flows from the subleased properties, which relied on certain assumptions made by management based on both internal and external data, such as the incremental borrowing rates used to discount these cash flows to its present values. As a result, these assets are classified within Level 3 of the fair value hierarchy.

Goodwill and Intangible Assets Disclosure [Abstract]
GOODWILL AND INTANGIBLE ASSETS	GOODWILL AND INTANGIBLE ASSETS The Company’s goodwill is the result of its acquisitions of other businesses and represents the excess of purchase consideration over the fair value of assets acquired and liabilities assumed. The Company performed its annual goodwill impairment analysis on August 31, 2022 and concluded that goodwill was not impaired, as the fair value of the reporting unit exceeded its carrying value. Additionally, no triggering events were identified as of December 31, 2022 that would more likely than not reduce the fair value of goodwill below its carrying value. The changes in the carrying amounts of goodwill during the years ended December 31, 2022 and 2021, were as follows (in thousands): Year Ended December 31, 2022 2021 Balance, beginning of period $ 105,128 $ 109,261 Effect of currency translation (2,800) (4,133) Balance, end of period $ 102,328 $ 105,128 Intangible assets as of December 31, 2022 and 2021 consisted of the following (dollars in thousands): December 31, 2022 Gross Accumulated Net Weighted Business relationships $ 9,918 $ (5,550) $ 4,368 6.2 years Developed technology 7,709 (7,709) — 0.0 years Licensing agreements 6,129 (1,505) 4,624 7.2 years Domain and data licenses 2,869 (2,864) 5 0.5 years Total $ 26,625 $ (17,628) $ 8,997 December 31, 2021 Gross Accumulated Net Weighted Business relationships $ 9,918 $ (4,786) $ 5,132 7.1 years Developed technology 7,709 (7,453) 256 0.2 years Licensing agreements 6,129 (860) 5,269 8.2 years Domain and data licenses 2,869 (2,853) 16 1.5 years Total $ 26,625 $ (15,952) $ 10,673 Amortization expense for the years ended December 31, 2022, 2021 and 2020 was $1.7 million, $2.8 million and $2.6 million, respectively.

The Company evaluated the associated ROU assets and leasehold improvements for impairment as a result of the subleases in accordance with Accounting Standards Codification Topic 360, “Property, Plant, and Equipment,” because the change in circumstances indicated that the carrying amount of such assets may not be recoverable. The Company compared the future undiscounted cash flows under the sublease agreement to the carrying amounts of the respective ROU assets and leasehold improvements and determined that an impairment existed. The Company compared the carrying values of the impacted assets to the fair values to determine the impairment amount related to the subleases. The Company recognized impairment charges of $10.5 million and $11.2 million during the years ended December 31, 2022 and 2021, respectively, which are included in general and administrative expenses on its consolidated statement of operations. The impairment charge during the year ended December 31, 2022 reduced the carrying amount of the ROU assets and leasehold improvements by $9.0 million and $1.5 million, respectively. The impairment charge during the year ended December 31, 2021 reduced the carrying amount of the ROU assets and leasehold improvements by $8.5 million and $2.7 million, respectively. For more information on the fair values of the ROU asset and leasehold improvements used in the impairment analysis, see Note 5, “ Fair Value Measurements . ” In December 2021, the Company terminated the lease for its office space in Washington, D.C. As a result, the Company recognized a net gain of $3.7 million, which includes certain termination-related fees and is included in general and administrative expenses on its consolidated statement of operations. The Company accelerated the depreciation of related leasehold improvements assets and recorded $5.2 million of depreciation expense for these assets during the year ended December 31, 2021.

Revenue from Contract with Customer [Abstract]
CONTRACT BALANCES	CONTRACT BALANCES The changes in the allowance for doubtful accounts during the years ended December 31, 2022, 2021 and 2020, were as follows (in thousands): Year Ended December 31, 2022 2021 2020 Balance, beginning of period $ 7,153 $ 11,559 $ 7,686 Add: provision for doubtful accounts 25,006 14,574 32,265 Less: write-offs, net of recoveries (22,882) (18,980) (28,392) Balance, end of period $ 9,277 $ 7,153 $ 11,559 The net increase in the allowance for doubtful accounts in the year ended December 31, 2022 was primarily related to an anticipated increase in customer delinquencies due to an increase in both the number of advertiser accounts and customer spend. The net decrease in the allowance for doubtful accounts in the year ended December 31, 2021 was primarily a result of a reduction in expected customer delinquencies compared to December 31, 2020, as collection rates improved. In calculating the allowance for doubtful accounts as of December 31, 2022 and 2021, the Company considered expectations of probable credit losses, including probable credit losses associated with the COVID-19 pandemic, based on observed trends in cancellations, observed changes in the credit risk of specific customers, the impact of anticipated closures and bankruptcies using forecasted economic indicators in addition to historical experience and loss patterns during periods of macroeconomic uncertainty. Contract liabilities consist of deferred revenue, which is recorded on the consolidated balance sheets when the Company has received consideration, or has the right to receive consideration, in advance of transferring the performance obligations under the contract to the customer. The changes in short-term deferred revenue during the years ended December 31, 2022 and 2021 were as follows (in thousands): Year Ended December 31, 2022 2021 Balance, beginning of period $ 4,156 $ 4,109 Less: recognition of deferred revenue from beginning balance (3,922) (3,279) Add: net increase in current period contract liabilities 4,966 3,326 Balance, end of period $ 5,200 $ 4,156 The majority of the Company’s deferred revenue as of December 31, 2022 is considered short-term and is expected to be recognized as revenue in the subsequent three-month period ending March 31, 2023. An immaterial amount of long-term deferred revenue is included in other long-term liabilities as of December 31, 2022. No other contract assets or liabilities are recorded on the Company’s consolidated balance sheets as of December 31, 2022 and 2021.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Legal Proceedings —In January 2018, a putative class action lawsuit alleging violations of the federal securities laws was filed in the U.S. District Court for the Northern District of California, naming as defendants the Company and certain of its officers (the “Securities Class Action”). The complaint, which the plaintiff amended on June 25, 2018, alleged violations of the Securities Exchange Act of 1934, as amended, by the Company and its officers for allegedly making materially false and misleading statements regarding its business and operations on February 9, 2017. The plaintiff sought unspecified monetary damages and other relief. On November 27, 2018, the Court granted in part and denied in part the defendants’ motion to dismiss. On October 22, 2019, the Court approved a stipulation to certify a class in this action and, on September 9, 2021, it denied the defendants’ motion for summary judgment. The case was scheduled for trial to begin on February 7, 2022. However, on December 3, 2021, the defendants reached a preliminary agreement with the plaintiff to settle this matter for $22.25 million. The proposed settlement was subsequently filed with the Court, which preliminarily approved it on July 25, 2022. The settlement was then funded by defendants’ insurers during the three months ended September 30, 2022. The Court entered an order granting final approval to the settlement on January 27, 2023, and on the same day entered judgment in the Securities Class Action. The settlement resolves all claims asserted against all defendants in the Securities Class Action without any liability or wrongdoing attributed to them. On August 26, 2022, the Court granted final approval of the settlement of a stockholder derivative action (the “Derivative Action”) asserting claims against certain current and former officers, and naming the Company as a nominal defendant, which arose out of the same facts as the Securities Class Action and was pending before the Court. The settlement resolved all claims asserted against all defendants in the Derivative Action without any liability or wrongdoing attributed to them personally or to the Company. Under the terms of the settlement, the Company’s board of directors adopted certain corporate governance modifications and the Company received $18.0 million of insurance proceeds. The Company has paid $3.75 million of such insurance proceeds to the plaintiff’s attorneys as fees. The remaining insurance proceeds funded the Securities Class Action settlement. The Company assesses, in conjunction with its legal counsel, the need to record a liability for litigation and contingencies, which it will accrue when it believes a loss is probable and the amount can be reasonably estimated. The Company believed the losses for both the settlements of the Securities Class Action and the Derivative Action were probable and the payment amounts described above, which totaled $26.0 million, represented reasonable estimates of loss contingencies. The Company also believed that the anticipated insurance proceeds related to the settlement of each action described above, which also totaled $26.0 million, were probable and represented reasonable estimates for loss recovery. Accordingly, the Company recorded a $26.0 million accrual for loss contingency within accounts payable and accrued liabilities as well as a $26.0 million receivable for loss recovery within prepaid expenses and other current assets during 2021, of which $3.75 million was released from each of the receivable for loss recovery and the accrual for loss contingency during the three months ended September 30, 2022 upon payment to the plaintiff's attorneys in the Derivative Action. As of December 31, 2022, the Company had a $22.25 million remaining accrual for the settlement of the Securities Class Action on its consolidated balance sheets within each of accounts payable and accrued liabilities as well as prepaid expenses and current assets. In January 2023, the Company released the remaining receivable and accrual upon the Court granting final approval of these settlements. On October 12, 2016, a putative class action lawsuit asserting claims against the Company was filed in the Superior Court of California for the County of San Francisco relating to alleged unlawful call recording and/or monitoring under the California Invasion of Privacy Act. Plaintiff seeks statutory damages and other relief. In response, the Company filed a motion for summary judgment, which the Court granted. Plaintiff appealed and, in October 2020, the California Court of Appeal for the First District reversed the decision of the trial court, and the California Supreme Court denied review. The case was then remanded to the Superior Court, where the Company subsequently amended its answer to add affirmative defenses, and Plaintiff amended his complaint to add additional named plaintiffs. On January 12, 2023, the Company filed another motion for summary judgment, and a hearing on that motion is scheduled for May 19, 2023. On January 18, 2023 the Court granted plaintiffs’ motion for class certification. On February 17, 2023, the Company filed a petition for a writ with the California Court of Appeal, seeking reversal of the lower court’s class certification decision. No date has been set for trial. The Company is subject to other legal proceedings arising in the ordinary course of business. Although the results of litigation and claims cannot be predicted with certainty, the Company currently does not believe that the final outcome of any of these other matters will have a material effect on the Company’s business, financial position, results of operations or cash flows. Indemnification Agreements —In the ordinary course of business, the Company may provide indemnifications of varying scope and terms to customers, vendors, lessors, business partners and other parties with respect to certain matters, including, but not limited to, losses arising out of the breach of such agreements, services to be provided by the Company or from intellectual property infringement claims made by third parties. In addition, the Company has entered into indemnification agreements with directors and certain officers and employees that require the Company to, among other things, indemnify them against certain liabilities that may arise by reason of their status or service as directors, officers or employees. While the outcome of claims cannot be predicted with certainty, the Company does not believe that the outcome of any claims under the indemnification arrangements will have a material effect on the Company’s financial position, results of operations or cash flows. Revolving Credit Facility —The Company is a party to a Credit Agreement with Wells Fargo Bank, National Association (the “Credit Agreement”), which provides for a three-year, $75.0 million senior unsecured revolving credit facility including a letter of credit sub-limit of $25.0 million. The commitments under the Credit Agreement expire on May 5, 2023. Interest on any borrowings under the revolving credit facility will accrue at either LIBOR plus 1.25% or at an alternative base rate plus 0.25%, at the Company’s election. Interest is payable monthly in arrears for base rate loans and at the end of the applicable interest period (or, if the interest period extends over three months, at the end of each three-month interval during the interest period) for LIBOR loans. The Company is also required to pay an annual commitment fee that accrues at 0.25% per annum on the unused portion of the aggregate commitments under the revolving credit facility, payable quarterly in arrears. Debt issuance-related costs were $0.4 million and are being amortized to interest expense on a straight-line basis over the life of the Credit Agreement. The Company is required to pay a fee that accrues at 0.70% per annum on the undrawn portion of any letter of credit, payable quarterly in arrears. As of December 31, 2022, the Company had $20.5 million of letters of credit under the sub-limit related to lease agreements for certain office locations, which are required to be maintained and issued to the landlords of each facility, and $54.5 million remained available under the revolving credit facility as of this date. The Company was in compliance with all covenants associated with the credit facility and there were no loans outstanding under the Credit Agreement as of December 31, 2022. See “ Liquidity and Capital Resources , ” included under Part II, Item 7 in this Annual Report for additional information on the covenants included in the Credit Agreement.

Common Stock Reserved for Future Issuance As of December 31, 2022, the Company had reserved shares of common stock for future issuances in connection with the following (in thousands): Number of Shares Stock options outstanding 3,543 RSUs and PRSUs outstanding 9,962 Available for future equity award grants 13,258 Available for future ESPP offerings 2,686 Total reserved for future issuance 29,449 Equity Incentive Plans The Company has outstanding awards under its 2012 Equity Incentive Plan, as amended (the “2012 Plan”). Under the 2012 Plan, the Company has the ability to issue incentive stock options, non-statutory stock options, stock appreciation rights, RSUs, restricted stock awards, performance units and performance shares. Additionally, the 2012 Plan provides for the grant of performance cash awards to employees, directors and consultants. On February 6, 2023, the Company adopted the Yelp Inc. 2023 Inducement Award Plan (the “Inducement Plan”), pursuant to which it reserved 1,400,000 shares of its common stock for issuance to individuals who were not previously employees of the Company, or who are returning to employment following a bona fide period of non-employment with the Company, as an inducement material to such persons entering into employment with the Company, in accordance with New York Stock Exchange Listed Company Manual Rule 303A.08. Under the Inducement Plan, the Company has the ability to issue non-statutory stock options, stock appreciation rights, RSUs, restricted stock awards, performance units and performance shares. The Inducement Plan also provides for the grant of performance cash awards to individuals eligible to receive awards under the Inducement Plan. Stock Options Stock options granted under the 2012 Plan are granted at a price per share not less than the fair value of a share of the Company’s common stock on the grant date. Options generally vest over a four-year period, on one of two schedules: (a) 25% vesting at the end of one year and the remaining shares vesting monthly thereafter or (b) ratably on a monthly basis. Options granted are generally exercisable for contractual terms of up to 10 years. The Company issues new shares when stock options are exercised. For the years ended December 31, 2022, 2021 and 2020, the weighted-average assumptions used for the Black-Scholes-Merton option valuation model were as follows: Year Ended December 31, 2022 2021 2020 Dividend yield — — — Annual risk-free rate 3.0 % 1.1 % 0.5 % Expected volatility 50.4 % 49.4 % 45.9 % Expected term (years) 6.0 6.0 5.7 A summary of stock option activity for the year ended December 31, 2022 is as follows: Number of Weighted- Weighted- Aggregate Outstanding at December 31, 2021 3,979 $ 32.59 4.4 $ 24,580 Granted 10 31.42 Exercised (306) 24.66 Canceled (140) 44.49 Outstanding at December 31, 2022 3,543 $ 32.81 3.6 $ 7,507 Options vested and exercisable at December 31, 2022 3,424 $ 32.73 3.4 $ 7,507 Aggregate intrinsic value represents the difference between the closing price of the Company’s common stock as quoted on the New York Stock Exchange on a given date and the exercise price of outstanding, in-the-money options. The total intrinsic value of options exercised was approximately $3.2 million, $13.8 million and $33.8 million for the years ended December 31, 2022, 2021 and 2020, respectively. The weighted-average grant date fair value of options granted was $16.07, $18.55 and $10.01 per share for the years ended December 31, 2022, 2021 and 2020, respectively. As of December 31, 2022, total unrecognized compensation costs related to unvested stock options was approximately $1.7 million, which the Company expects to recognize over a weighted-average time period of 1.7 years. RSUs RSUs generally vest over a four-year period, on one of two schedules: (a) 25% vesting at the end of one year and the remaining vesting quarterly thereafter or (b) ratably on a quarterly basis. RSUs also include PRSUs, which are subject to either (a) a market condition or (b) the achievement of performance goals. PRSUs may also be subject to a time-based vesting schedule of quarterly over four years (the “Time-Based Vesting Schedule”). For PRSUs subject to a market condition, the Company recognizes expense from the date of grant. For PRSUs subject to performance goals, the Company recognizes expense when it is probable that the performance condition will be achieved. The Company granted PRSUs subject to market conditions in 2019 and 2022. The shares underlying each PRSU award granted in 2019 will be eligible to vest only if the average closing price of the Company’s common stock equaled or exceeded $45.3125 over any 60-day trading period during the four years following the grant date of February 7, 2019. If this market condition is met, the shares underlying each PRSU award will vest according to the Time-Based Vesting Schedule. Any shares subject to the PRSUs that have met the Time-Based Vesting Schedule at the time the market condition is achieved will fully vest as of such date; thereafter, any remaining nonvested shares subject to the PRSUs will continue vesting solely according to the Time-Based Vesting Schedule, subject to the applicable employee's continued service as of each such vesting date. Based on the performance of the Company’s stock over the four years following the grant date, the market condition for the 2019 PRSUs was not achieved and the Company expects the shares underlying these awards to return to the pool of shares reserved for future issuance under the 2012 Plan following certification of this result in the first quarter of 2023. The shares underlying each PRSUs granted in 2022 that is subject to market conditions vest based on the relative performance of the Company’s total stockholder return (“TSR”) over a three-year period. A percentage of the target number of shares underlying each award, ranging from zero to 200%, will vest based on the percentile rank of the Company’s TSR relative to that of the other companies in the Russell 2000 index over the period beginning January 1, 2022 and ending December 31, 2024. The Company’s TSR, as well as the TSR of the other companies in the Russell 2000 Index, will be calculated based on the average closing price of each company’s stock over the last 20 trading days of the performance period compared to the average closing price over the first 20 trading days of the performance period. Any shares that become eligible to vest based on the Company’s level of achievement of the market goal will fully vest on or following certification of the Company’s performance on February 20, 2025 or, if the certification occurs following such date, March 15, 2025, subject to the applicable employee’s continued service as of such vesting date. For PRSUs subject to performance goals, a percentage of the target number of shares, ranging from zero to 200%, will become eligible to vest based on the Company’s level of achievement of certain financial targets, subject to the Time-Based Vesting Schedule. The shares subject to performance goals become eligible to vest once the achievement against the financial targets is known, which will be no later than March of the following year. On the quarterly vest date immediately following such determination (or a vest date otherwise specified in the agreement), the eligible shares, if any, will vest to the extent that the employee has met the Time-Based Vesting Schedule as of such date. Thereafter, the eligible shares will continue to vest in accordance with the Time-Based Vesting Schedule, subject to the applicable employee’s continued service as of each such vesting date. The Company performed an analysis as of December 31, 2022 to assess the probability of achievement of the PRSU financial targets and, as a result, recorded compensation costs in the year ended December 31, 2022 for the PRSUs that it expected to vest. As the PRSU activity during the year ended December 31, 2022 was not material, it is presented together with the RSU activity in the table below. A summary of RSU and PRSU activity for the year ended December 31, 2022 is as follows (in thousands, except per share amounts): Number of Shares Weighted- Average Grant Date Fair Value Nonvested at December 31, 2021 10,016 $ 32.39 Granted 6,807 34.89 Vested (1) (4,786) 33.40 Canceled (2,075) 33.05 Nonvested at December 31, 2022 (2) 9,962 $ 33.48 (1) Includes 1,894,504 shares that vested but were not issued due to the Company’s use of Net Share Withholding for payment of employee taxes. (2) Includes 656,659 PRSUs. The aggregate fair value as of the vest date of RSUs and PRSUs that vested during the years ended December 31, 2022, 2021 and 2020 was $155.0 million, $164.5 million and $95.0 million, respectively. As of December 31, 2022, the Company had approximately $305.5 million of unrecognized stock-based compensation expense related to RSUs and PRSUs, which it expects to recognize over the remaining weighted-average vesting period of approximately 2.5 years. Employee Stock Purchase Plan The ESPP allows eligible employees to purchase shares of the Company’s common stock at a discount through payroll deductions of up to 15% of their eligible compensation, subject to any plan limitations, during designated six-month offering periods. At the end of each offering period, employees are able to purchase shares at 85% of the fair market value of the Company’s common stock on the last day of the offering period, based on the closing sales price of the Company’s common stock as quoted on the New York Stock Exchange on such date. During the years ended December 31, 2022, 2021 and 2020, employees purchased 627,485, 517,309 and 662,063 shares, respectively, at a weighted-average purchase price per share of $25.55, $31.58 and $21.47, respectively. The Company recognized stock-based compensation expense related to the ESPP of $2.8 million, $3.0 million and $2.5 million in the years ended December 31, 2022, 2021 and 2020, respectively.

Beginning in 2022, additional changes under the U.S. Tax Cuts and Jobs Act came into effect, including the mandatory capitalization and amortization of research and development expenses. These provisions require the Company to capitalize research and experimental expenditures and amortize them on the U.S. tax return over five or fifteen years, depending on where research is conducted. This required capitalization results in an overall increase in provision for income taxes (including an increase in GILTI as well as the overall effective tax rate in 2022) and in DTAs. Deferred Tax Balances Deferred income taxes reflect the net tax effects of temporary differences between carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The following table presents the significant components of the Company’s deferred tax assets and liabilities for the periods presented (in thousands): As of December 31, 2022 2021 Deferred tax assets: Reserves and others $ 4,803 $ 4,963 Stock-based compensation 20,214 21,749 Net operating loss carryforward 1,754 3,064 Tax credit carryforward 34,462 47,340 Capitalized research and development 84,390 9,408 Operating lease liabilities 30,394 40,616 Gross deferred tax assets 176,017 127,140 Valuation allowance (34,303) (32,815) Total deferred tax assets 141,714 94,325 Deferred tax liabilities: Depreciation and amortization (13,955) (14,914) Deferred contract costs (6,750) (4,372) Operating lease right-of-use assets (23,631) (34,515) Total deferred tax liabilities (44,336) (53,801) Net deferred tax assets $ 97,378 $ 40,524 As of December 31, 2022, the Company had federal and state net operating loss carryforwards of approximately $4 million and $22.6 million, respectively, expiring beginning in 2037 and 2025, respectively. As of December 31, 2022, the Company's wholly owned subsidiary, Yelp GmbH (Germany), had net operating loss carryforwards of $0.5 million, which have an indefinite carryforward period. The Company had federal research credit carryforwards of approximately $0.4 million (gross) that begin to expire in 2031, if unused; California research credit carryforwards of approximately $70.7 million (gross) that do not expire; and Canada research credit carryforwards of approximately $1.6 million (gross) that begin to expire in 2041. Utilization of net operating loss carryforwards and credits may be subject to a substantial annual limitation due to the ownership change limitations provided by the Internal Revenue Code of 1986, as amended, and similar state provisions. The annual limitation may result in the expiration of net operating losses and credits before utilization. The Company does not expect any previous ownership changes, as defined under Section 382 and 383 of the Internal Revenue Code, to result in a limitation that will materially reduce the total amount of net operating loss carryforwards and credits that can be utilized. Further, foreign loss carryforwards may be subject to limitations under the applicable laws of the taxing jurisdictions due to ownership change limitations. As of December 31, 2022, the Company had accumulated undistributed earnings generated by its foreign subsidiaries of approximately $16.9 million. The Company continues to assert that all its foreign earnings are to be permanently reinvested and expects future U.S. cash generation to be sufficient to meet future U.S. cash needs. As such, the Company has not recognized a deferred tax liability related to unremitted foreign earnings. Deferred Tax Valuation Allowance As more fully described in “Income Taxes” in Note 2, “ Summary of Significant Accounting Policies ,” the Company maintains valuation allowances against deferred tax balances where appropriate and considers all positive and negative evidence that the Company would have future taxable income sufficient to realize the benefit of its deferred tax assets. Valuation allowances of $34.3 million and $32.8 million primarily related to California state tax credits were recorded against the Company’s net deferred tax asset balances as of December 31, 2022 and 2021, respectively. Since the Company mainly conducts research and development activities in California but earns a substantial portion of its U.S. income in other states, the Company could not assert, at the required more-likely-than-not level of certainty, that it would generate future taxable California income sufficient to realize the benefit of these deferred tax assets. Accordingly, the Company maintained a valuation allowance against specific state credits. Unrecognized Tax Benefits A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in thousands): Year Ended December 31, 2022 2021 2020 Balance at the beginning of the year $ 52,605 $ 48,207 $ 40,718 Increase (decrease) based on tax positions related to the prior year 61 (291) (453) Increase based on tax positions related to the current year 7,455 10,750 7,942 Lapse of statute of limitations (357) (6,061) — Balance at the end of the year $ 59,764 $ 52,605 $ 48,207 As of December 31, 2022, the Company had $30.9 million of unrecognized tax benefits that, if recognized, would affect the effective tax rate. The Company’s policy is to record interest and penalties related to unrecognized tax benefits as income tax expense. During each of the years ended December 31, 2022, 2021 and 2020, the Company recorded an immaterial amount of interest and penalties. In addition, the Company is subject to the continuous examination of its income tax returns by the IRS and other tax authorities. The Company’s federal and state income tax returns for fiscal years subsequent to 2003 remain open to examination. In the Company’s foreign jurisdictions — Canada, Ireland, United Kingdom and Germany — the tax years subsequent to 2017 remain open to examination. The Company regularly assesses the likelihood of adverse outcomes resulting from examinations to determine the adequacy of its provision for income taxes, and monitors the progress of ongoing discussions with tax authorities and the impact, if any, of the expected expiration of the statute of limitations in various taxing jurisdictions. The Company believes that an adequate provision has been made for any adjustments that may result from tax examinations. However, the outcome of tax audits cannot be predicted with certainty. If any issues addressed in the Company’s tax audits are resolved in a manner not consistent with management’s expectations, the Company could be required to adjust its provision for income taxes in the period such resolution occurs. Although the timing of the resolution or closure of audits is not certain, the Company believes that it is reasonably possible that unrecognized tax benefits will not be reduced within the next 12 months.

Earnings Per Share [Abstract]
NET INCOME (LOSS) PER SHARE ATTRIBUTABLE TO COMMON STOCKHOLDERS	NET INCOME (LOSS) PER SHARE ATTRIBUTABLE TO COMMON STOCKHOLDERSBasic net income (loss) per share attributable to common stockholders is computed using the weighted-average number of outstanding shares of common stock during the period. Diluted net income (loss) per share attributable to common stockholders is computed using the weighted-average number of outstanding shares of common stock and the effect of potentially dilutive securities outstanding during the period. Potentially dilutive securities include stock options, RSUs (including PRSUs) and, to a lesser extent, ESPP shares. If dilutive, such potentially dilutive securities are reflected in net income (loss) per share attributable to common stockholders using the treasury stock method. The following tables present the calculation of basic and diluted net income (loss) per share attributable to common stockholders for the periods presented (in thousands, except per share data): Year Ended December 31, 2022 2021 2020 Basic net income (loss) per share: Net income (loss) attributable to common stockholders $ 36,347 $ 39,671 $ (19,424) Shares used in computation: Weighted-average common shares outstanding 70,867 74,221 73,005 Basic net income (loss) per share attributable to common stockholders: $ 0.51 $ 0.53 $ (0.27) Year Ended December 31, 2022 2021 2020 Diluted net income (loss) per share: Net income (loss) attributable to common stockholders $ 36,347 $ 39,671 $ (19,424) Shares used in computation: Weighted-average common shares outstanding 70,867 74,221 73,005 Stock options 474 786 — RSUs 2,058 3,607 — ESPP 3 2 — Number of shares used in diluted calculation 73,402 78,616 73,005 Diluted net income (loss) per share attributable to common stockholders: $ 0.50 $ 0.50 $ (0.27) The following stock-based instruments were excluded from the calculation of diluted net income (loss) per share attributable to common stockholders because their effect would have been anti-dilutive for the periods presented (in thousands): Year Ended December 31, 2022 2021 2020 Stock options 2,030 1,541 4,623 RSUs 853 59 9,758 ESPP — — 62

Segment Reporting [Abstract]
INFORMATION ABOUT REVENUE AND GEOGRAPHIC AREAS	INFORMATION ABOUT REVENUE AND GEOGRAPHIC AREAS The Company considers operating segments to be components of the Company for which separate financial information is available and evaluated regularly by the Company’s chief operating decision maker in deciding how to allocate resources and in assessing performance. The chief operating decision maker for the Company is the chief executive officer. The chief executive officer reviews financial information presented on a consolidated basis, accompanied by information about revenue by product line and geographic region for purposes of allocating resources and evaluating financial performance. The Company has determined that it has a single operating and reporting segment. When the Company communicates results externally, it disaggregates net revenue into major product lines and primary geographical markets, which is based on the billing address of the customer. The disaggregation of net revenue by major product lines is based on the type of service provided and also aligns with the timing of revenue recognition for each. To reflect the Company’s strategic focus on creating differentiated experiences for its Services categories and Restaurants, Retail & Other categories, the Company further disaggregates advertising revenue to reflect these two high-level category groupings. The Services categories consist of the following businesses: home, local, auto, professional, pets, events, real estate and financial services. The Restaurants, Retail & Other categories consist of the following businesses: restaurants, shopping, beauty & fitness, health and other. Net Revenue The following table presents the Company’s net revenue by major product line (and by category for advertising revenue) for the periods presented (in thousands): Year Ended December 31, 2022 2021 2020 Net revenue by product: Advertising revenue by category (1) : Services $ 693,810 $ 607,770 $ 515,019 Restaurants, Retail & Other 440,593 377,455 321,096 Advertising 1,134,403 985,225 836,115 Transactions 14,063 13,196 15,017 Other 45,040 33,418 21,801 Total net revenue $ 1,193,506 $ 1,031,839 $ 872,933 (1) Beginning in 2021, advertising revenue by category reflects an updated method of disaggregation. Prior-year amounts have not been updated as it is impracticable to do so, given certain historical information is not available. During the years ended December 31, 2022, 2021 and 2020, no individual customer accounted for 10% or more of consolidated net revenue. As a result of the COVID-19 pandemic, the Company considered whether there was any impact to the manner in which it recognizes revenue, in particular with respect to the collectability criteria for recognizing revenue from contracts with customers. The Company did not change the manner in which it recognizes revenue as a result of that assessment. The Company offered a number of relief incentives to advertising and other revenue customers most impacted by the COVID-19 pandemic totaling $0.4 million, $3.5 million and $22.6 million during the years ended December 31, 2022, 2021 and 2020, respectively. These incentives were primarily in the form of waived advertising and subscription fees. The Company accounted for these incentives as price concessions and reduced net revenue recognized in the years ended December 31, 2022, 2021 and 2020 accordingly. During the year ended December 31, 2020, the Company also paused certain advertising campaigns that were scheduled to run from April to May 2020 and offered certain free advertising products during those months with a total value of $14.5 million. All paused advertising campaigns that were not cancelled by customers resumed by the end of May 2020. The following table presents the Company’s net revenue by major geographic region for the periods presented (in thousands): Year Ended December 31, 2022 2021 2020 United States $ 1,185,202 $ 1,023,143 $ 863,300 All other countries 8,304 8,696 9,633 Total net revenue $ 1,193,506 $ 1,031,839 $ 872,933 Long-Lived Assets The following table presents the Company’s long-lived assets by major geographic region for the periods presented (in thousands): As of December 31, 2022 2021 United States $ 72,325 $ 79,027 All other countries 4,899 4,830 Total long-lived assets $ 77,224 $ 83,857

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2022
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation —The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). All intercompany balances and transactions have been eliminated upon consolidation. Certain reclassifications have been made to the consolidated financial statements of prior periods and the accompanying notes to conform to the current period presentation.
Use of Estimates	Use of Estimates —The preparation of the Company’s consolidated financial statements in conformity with GAAP requires management to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of income and expenses during the reporting period. Items that require estimates, judgments or assumptions include, but are not limited to, determining variable consideration and identifying the nature and timing of satisfaction of performance obligations, allowance for doubtful accounts and credit losses, fair value and estimated useful lives of long- and indefinite-lived assets, litigation loss contingencies, liabilities related to incurred but not reported insurance claims, fair value and achievement of targets for performance-based restricted stock units (“PRSUs”) and income taxes. These estimates, judgments and assumptions are based on information available as of the date of the consolidated financial statements; therefore, actual results could differ from management’s estimates due to macroeconomic uncertainty and other factors.
Foreign Currency Translation	Foreign Currency Translation —The consolidated financial statements of the Company’s foreign subsidiaries are measured using the local currency as the functional currency. Assets and liabilities of foreign subsidiaries are translated at exchange rates in effect as of the balance sheet date. Revenues and expenses are translated at average exchange rates in effect during the year. Translation adjustments are recorded within accumulated other comprehensive loss, a separate component of stockholders’ equity.
Cash and Cash Equivalents	Cash and Cash Equivalents —The Company considers all highly liquid investments, such as treasury bills, commercial paper, certificates of deposit and money market instruments with maturities of three months or less at the time of acquisition to be cash equivalents. Cash and cash equivalents primarily consist of amounts held in interest-bearing money market funds that were readily convertible to cash. The fair value of cash and cash equivalents approximates their carrying value.
Marketable Securities	Marketable Securities —The Company considers highly liquid treasury notes, U.S. agency securities, corporate debt securities, money market funds and other funds with maturities of more than three months to be marketable securities. These securities are classified as short-term marketable securities on the consolidated balance sheets as they represent the investment of cash available for current operations. The Company has a policy that generally requires its securities to be investment grade (i.e., rated ‘A’ or higher by bond rating firms) with the objective of minimizing the potential risk of principal loss. The Company classifies its marketable securities as available-for-sale and determines the classification at the time of purchase based on its investment strategy; it reevaluates such designation at each balance sheet date. Available-for-sale securities are stated at fair value as of each balance sheet date and are periodically assessed for impairment. An investment is impaired if the fair value of the investment is less than its amortized cost basis. The Company reviews the securities in an unrealized loss position and evaluates whether credit loss exists by considering factors such as historical experience, market data, issuer-specific factors including their credit rating, and current economic conditions. If a credit loss exists, the Company measures the loss by comparing the present value of cash flows expected to be collected from the security with the amortized cost basis of the security. An allowance for credit loss is recorded as a component of other income (expense), net, limited by the amount of unrealized loss. Any remaining unrealized losses are recorded to other comprehensive income (loss). The Company determines any realized gains or losses on the sale of marketable securities on a specific identification method and records such gains and losses as a component of other income (expense), net. Amortization of premiums and accretion of discounts are included in interest income. If the Company has the intent to sell an available-for-sale security in an unrealized loss position or it is more likely than not that it will be required to sell the security prior to recovery of its amortized cost basis, any previously recorded allowance is reversed and the entire difference between the amortized cost basis of the security and its fair value is recognized in the consolidated statements of operations.
Concentrations of Credit Risk	Concentrations of Credit Risk —Financial instruments that potentially subject the Company to concentration of credit risk consist primarily of cash and cash equivalents, marketable securities and other investments, and accounts receivable. The Company places its cash and cash equivalents, marketable securities and other investments with major financial institutions, which management assesses to be of high credit quality, in order to limit the exposure of each investment.
Accounts Receivable, Net and Payment Terms	Accounts Receivable, Net, and Payment Terms—The timing of revenue recognition may differ from the timing of invoicing to customers. The Company records an accounts receivable balance when revenue is recognized prior to or at the time of invoicing the customer. Payment terms and conditions vary by contract type and the service being provided. For advertising services, the Company typically invoices customers on a monthly basis, one month in arrears, with payment due either at the end of each billing period or up to 30 days after the end of the billing period. For transaction services, the Company collects its commission fee on each transaction either at the time of the transaction or up to 30 days after the end of the billing period. For subscription services, the Company typically invoices customers one month in advance, with payment due at the beginning of each billing period.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts —The Company maintains an allowance for doubtful accounts receivable. The allowance reflects the Company's best estimate of probable losses associated with the accounts receivable balance. It is based upon historical experience and loss patterns, the number of days that billings are past due, an evaluation of the potential risk of loss associated with delinquent accounts based on the credit risk of those accounts, known delinquent accounts, as well as current conditions and reasonable and supportable economic forecasts. When new information becomes available that allows the Company to more accurately estimate the allowance, it makes an adjustment, which is considered a change in accounting estimate. The carrying value of accounts receivable approximates their fair value.
Deferred Contract Costs and Cost of Revenue	Deferred Contract Costs —The Company has determined that certain sales incentive compensation costs are incremental costs to obtain the related contract. These costs are capitalized in the period in which they are incurred and amortized on a straight-line basis over the expected customer life of the associated contract. The Company uses a straight-line basis as it expects the benefit of these costs to be realized uniformly over the amortization period. The amortization periods for contract costs, which extend up to 32 months, were determined based on both qualitative and quantitative factors, including product life cycle attributes and customer retention historical data. For contract costs with amortization periods of less than 12 months, the Company applies a practical expedient to expense such costs as incurred. The Company assesses deferred contract costs for impairment on a quarterly basis. No impairment charges were recorded in the periods presented. Amortized contract costs are recorded within sales and marketing expense in the consolidated statements of operations. Deferred contract costs are included within other non-current assets on the Company’s consolidated balance sheets (see Note 10, “ Other Non-Current Assets ”). Cost of Revenue —The Company’s cost of revenue primarily consists of credit card processing fees, website infrastructure expense, which includes website hosting costs, and salaries, benefits and stock-based compensation expense for the infrastructure teams responsible for operating the Company’s website and mobile app, and excludes depreciation and amortization expense. Cost of revenue also includes third-party advertising fulfillment costs.
Deferred Revenue and Revenue Recognition	Deferred Revenue —The Company records deferred revenue when it has received consideration, or has the right to receive consideration, in advance of the transfer of the performance obligations of the contract to the customer. Revenue Recognition —The Company generates revenue from the sale of advertising products, transactions with consumers and other revenue sources, which correspond to the Company’s major product lines. The Company recognizes revenue by applying the following steps: the contract with the customer is identified; the performance obligations in the contract are identified; the transaction price is determined; the transaction price is allocated to the performance obligations in the contract; and revenue is recognized when (or as) the Company satisfies these performance obligations in an amount that reflects the consideration it expects to be entitled to in exchange for those services. The Company applies the portfolio practical expedient to account for the vast majority of contracts with customers in each category of revenue. The Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which the amount of revenue it recognizes is equal to the amount which the Company has a right to invoice. Contracts with customers can include multiple performance obligations, where the transaction price is allocated to each performance obligation based on its relative standalone selling price (“SSP”). The Company determines SSP based on the prices of the promised goods or services charged when sold separately to customers, which are determined using contractually stated prices. The Company allocates revenue to each of the performance obligations included in a contract with multiple performance obligations at the inception of the contract. The various products and services comprising contracts with multiple performance obligations are typically capable of being both distinct and distinct within the context of the arrangement and are accounted for as separate performance obligations. For all contracts with customers, estimates and assumptions include determining variable consideration and identifying the nature and timing of satisfaction of performance obligations. The Company may accept lower consideration than the amount promised per the contract for certain revenue transactions and certain customers may receive cash based incentives, credits or refunds, which are accounted for as variable consideration when estimating the amount of revenue to recognize. The Company estimates these amounts based on the expected amount to be provided to customers and constrains the revenue. The Company believes that there will not be a significant reversal in the amount of cumulative revenue recognized when the uncertainty associated with the estimates of variable consideration is subsequently resolved. For contracts satisfied over time, the Company applies the invoice practical expedient to depict the value transferred to the customer and measure of progress towards completion of its obligations. The Company considers the right to receive consideration from a customer to correspond directly with the value to the customer of its performance completed to date. The Company does not consider the effects of the time value of money as substantially all of the Company’s contracts are invoiced on a monthly basis, one month in arrears. Revenue is recognized net of any taxes collected from customers, which are remitted to governmental authorities. The Company does not typically refund customers for services once it determines the performance obligations of the contract have been satisfied, but will assess any refund requests from customers and partners on a case by case basis. The Company records an allowance for potential future refunds, which is estimated based on historical trends and recorded as a reduction of net revenue. Advertising . The Company generates advertising revenue primarily through the display of advertising products on its website and mobile app. These arrangements are evidenced by either written or electronic acceptance of a contract that stipulates the types of advertising to be delivered, the timing and pricing. Performance-based advertising placements are priced on a cost-per-click basis, while impression-based advertising placements are priced on a cost per thousand impressions basis. The Company recognizes revenue from the delivery of performance-based ads and impression-based ads in the period of delivery, in each case net of customer discounts. The Company also offers businesses premium features in connection with their business pages pursuant to fixed monthly fees, and recognizes revenue from such offerings over the service period. The Company also generates advertising revenue through indirect sales of advertising products, such as through reseller contracts that allow partners to sell Yelp Branded Profiles to their clients and the monetization of remnant advertising inventory through third-party ad networks, and recognizes revenue in the period of delivery. Transactions . The Company generates transactions revenue primarily from revenue-sharing partner contracts. The Company’s transactions platform provides consumers with the ability to place food orders for pickup and delivery through third parties, primarily Grubhub, or complete other transactions directly on Yelp. The Company earns a per-transaction commission fee pursuant to partnership contracts for acting as an agent for these transactions, which it recognizes on a net basis and includes in revenue upon completion of a transaction. Other Revenue . The Company generates other revenue through subscription services contracts, such as sales of monthly subscriptions to Yelp Guest Manager, licensing contracts for access to Yelp data, and other non-advertising, non-transaction partnerships. Subscription revenues are recognized ratably over the contract terms beginning on the commencement date of each contract, which is the date the service is made available to customers.
Property, Equipment and Software	Property, Equipment and Software —Property, equipment and software are stated at cost less accumulated depreciation and amortization. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, which are approximately three
Website and Internal-Use Software Development Costs	Website and Internal-Use Software Development Costs —Costs related to website and internal-use software are primarily related to the Company’s website and mobile app, including support systems. The Company capitalizes its costs to develop software when: preliminary development efforts are successfully completed; management has authorized and committed project funding; and it is probable that the project will be completed and the software will be used as intended. Costs incurred for enhancements that are expected to result in additional material functionality are capitalized and amortized over the estimated useful life of the upgrades. Such costs are amortized on a straight-line basis over the estimated useful life of the related asset, which is generally three years. The Company capitalizes certain implementation costs incurred related to cloud computing arrangements that are service contracts. Such costs are amortized on a straight-line basis over the term of the associated hosting arrangement plus any reasonably certain renewal period. Any capitalized amounts related to such arrangements are recorded within prepaid expense and other current assets and within non-current assets on the consolidated balance sheets.
Leases	Leases —The Company leases its office facilities under operating lease agreements that expire from 2023 to 2031, some of which include options to renew at the Company’s sole discretion. If exercised, such options would extend the lease terms by up to ten years. Additionally, certain lease agreements contain options to terminate the leases, which require 6 to 12 months prior written notice to the landlord. The Company does not have any finance lease agreements. The Company determines if an arrangement contains a lease at inception. The Company recognizes on its consolidated balance sheets operating lease liabilities representing the present value of future lease payments, and an associated operating lease right-of-use asset for any operating lease with a term greater than one year. The Company recognizes the amortization of the right-of-use asset each month within lease expense. The Company elected to use the practical expedient for short-term leases, and therefore does not record operating lease right-of-use assets or lease liabilities associated with leases with durations of 12 months or less. When recording the present value of lease liabilities, a discount rate is required. The Company has concluded that the rates implicit in the various operating lease agreements are not readily determinable. As a result, the Company instead uses its incremental borrowing rate, which is calculated based on hypothetical borrowings to fund each respective lease over the lease term, as of the lease commencement date, assuming that borrowings are secured by the various leased properties. The incremental borrowing rates are determined based on an assessment of the Company’s implied credit rating, using ratings scales from reputable rating agencies that consider a number of qualitative and quantitative factors. Market rates are derived as of the lease commencement dates with reference to companies with the same debt rating that operate in a similar industry to the Company. The Company does not recognize its renewal options as part of its right-of-use assets and lease liabilities until it is reasonably certain that it will exercise such renewal options. The Company does not combine lease and non-lease components; its lease agreements provide specific allocations of the Company’s obligations between lease and non-lease components. As a result, the Company is not required to exercise any judgment in determining such allocations.
Goodwill	Goodwill—Goodwill represents the excess of the purchase price in a business combination over the fair value of net tangible and intangible assets acquired. The carrying amount of goodwill is reviewed at least annually, or more frequently if events or changes in circumstances indicate that the carrying value of goodwill may not be recoverable. The Company has the option to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the Company determines that it is more likely than not that its fair value is less than the carrying amount, or opts not to perform a qualitative assessment, then the Company will compare the fair value of a reporting unit with its carrying amount and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value.
Intangible Assets	Intangible Assets—Intangible assets include acquired intangible assets identified through business combinations, which are carried at fair value less accumulated amortization, and purchased intangible assets, which are carried at cost less accumulated amortization. Amortization is recorded over the estimated useful lives of the assets, generally two years to 12 years. The Company reviews amortizable intangible assets to be held and used for impairment whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable. Determination of recoverability is based on the lowest level of identifiable estimated undiscounted cash flows resulting from the use of the asset and its eventual disposition. Measurement of any impairment loss is based on the excess of the carrying value of the asset over its fair value.
Impairment of Long-Lived Assets and Long-Lived Assets to be Disposed of	Impairment of Long-Lived Assets and Long-Lived Assets to Be Disposed of —The Company evaluates its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell.
Stock Repurchases	Stock Repurchases —The Company accounts for repurchases of its common stock by recording the cost to repurchase those shares to treasury stock, a separate component of stockholders’ equity. Upon retirement, the carrying amount of treasury stock is reduced with a corresponding reduction to par value of common stock, with any excess of the cost incurred to repurchase shares over their par value recorded as an adjustment to retained earnings (accumulated deficit) on the date of retirement.
Research and Development	Research and Development—The Company incurs research and development expenses for costs it incurs in research aimed at developing, and in translating the results of such research into, new products and services or significant improvements to existing products or services intended for internal use. Such costs are considered research and development and are expensed as incurred. These expenses primarily consist of employee-related costs (including stock-based compensation) for the Company’s engineers and other employees engaged in the research and development of its products and services, as well as allocated indirect overhead costs.
Stock-Based Compensation	Stock-Based Compensation —The Company accounts for stock-based employee compensation plans under the fair value recognition and measurement provisions, which require all stock-based payments to employees, including grants of stock options, restricted stock awards, restricted stock units (“RSUs”), PRSUs and issuances under its 2012 Employee Stock Purchase Plan, as amended (“ESPP”), to be measured based on the grant-date fair value of the awards. The Company accounts for forfeitures as they occur. The Company estimates the fair value of options granted to employees on the grant date using the Black-Scholes-Merton option valuation model. This valuation model for stock-based compensation expense requires the Company to make assumptions and judgments about the variables used in the calculation, including the expected term (weighted-average period of time that the options granted are expected to be outstanding), the expected volatility in the fair market value of the Company’s common stock, a risk-free interest rate and expected dividends. No compensation cost is recorded for options that do not vest. The Company uses the simplified calculation of expected life as it does not have sufficient appropriate historical exercise data on which to base its own estimate. Expected volatility is based on an average of the historical volatilities of the common stock of several entities with characteristics similar to those of the Company. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for periods corresponding with the expected life of the option. The Company recognizes compensation cost related to options using the straight-line method. The fair value of RSUs is measured using the closing price of the Company’s common stock on the New York Stock Exchange on the grant date. The Company recognizes compensation cost related to RSUs using the straight-line method. No compensation cost is recorded for RSUs that do not vest. In May 2020, the Company changed its method of settling the employee tax liabilities associated with the vesting of RSUs from withholding a portion of the vested shares and covering such taxes with cash from its balance sheet (“Net Share Withholding”), to selling a portion of the vested shares to cover taxes. In November 2020, the Company reverted its method of settling these employee tax liabilities to Net Share Withholding. The Company has two types of PRSUs outstanding — awards for which the vesting is subject to both a time-based vesting schedule and either (a) a market condition or (b) the achievement of performance goals. For the awards subject to a market condition, the Company uses a Monte Carlo model to determine the fair value of the PRSUs. The Company recognizes compensation cost related to PRSUs using the accelerated method. Compensation costs are recorded if the service condition is met regardless of whether the market performance condition is satisfied. No compensation cost is recorded if the service condition is not met. For the awards subject to performance goals, compensation costs are recorded when the Company concludes that it is probable that the performance conditions will be achieved. The Company performs an analysis in each reporting period to determine the probability that the performance goals will be met, and recognizes a cumulative catch-up adjustment to compensation cost for changes in its probability assessment in subsequent reporting periods, if required, until the performance period has expired. The fair value of the PRSUs is measured using the closing price of the Company's common stock on the New York Stock Exchange on the grant date. The Company recognizes compensation cost related to PRSUs using the accelerated method. No compensation cost is recorded if the service condition is not met.
Advertising Expenses	Advertising Expenses—Advertising costs are expensed in the period in which the advertising takes place. Costs of producing advertising are expensed in the period in which production takes place.
Comprehensive Income (Loss)	Comprehensive Income (Loss) —Comprehensive income (loss) consists of net income (loss) and other comprehensive income (loss), which consists of foreign currency adjustments and unrealized loss on available-for-sale debt securities, net of tax.
Income Taxes	Income Taxes —The Company records income taxes using the asset and liability method, which requires the recognition of deferred tax assets (“DTAs”) and liabilities for the expected future tax consequences of events that have been recognized in the Company’s financial statements or tax returns. In estimating future tax consequences, the Company generally considers all expected future events other than enactments or changes in the tax law or rates. In assessing the realization of deferred tax assets, the Company considers whether it is more likely than not that all or some portion of deferred tax assets will not be realized. The ultimate realization of the deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Valuation allowances are provided to reduce deferred tax assets to the amount that is more likely than not to be realized. In determining the need for a valuation allowance, the weight given to positive and negative evidence is commensurate with the extent to which the evidence may be objectively verified. The Company evaluates the ability to realize net deferred tax assets and the related valuation allowance on a quarterly basis. The Company operates in various tax jurisdictions and is subject to audit by various tax authorities. The Company provides for tax contingencies whenever it is deemed probable that a tax asset has been impaired or a tax liability has been incurred for events such as tax claims or changes in tax laws. Tax contingencies are based upon their technical merits, relative tax law and the specific facts and circumstances as of each reporting period. Changes in facts and circumstances could result in material changes to the amounts recorded for such tax contingencies. The Company recognizes a tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement.
Employee Benefit Plan	Employee Benefit Plan—The Company sponsors a qualified 401(k) defined contribution plan covering eligible employees. Participants may contribute a portion of their annual compensation up to a maximum annual amount set by the Internal Revenue Service (“IRS”).
Insurance	Insurance —The Company is self-insured for certain employee benefits including medical, dental and vision; however, the Company obtains third-party excess insurance coverage to limit its exposure to certain claims. Liabilities associated with these benefits include estimates of both claims filed and losses incurred but not yet reported. The Company utilizes valuations provided by reputable, independent third-party actuaries. The Company’s self-insured liabilities are included in the consolidated balance sheets within accounts payable and accrued liabilities.
