Organization, Consolidation and Presentation of Financial Statements [Abstract]
DESCRIPTION OF BUSINESS AND BASIS FOR PRESENTATION	DESCRIPTION OF BUSINESS AND BASIS FOR PRESENTATION 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 Condensed 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. Basis of Presentation The accompanying interim condensed consolidated financial statements are unaudited. These unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") and the applicable rules and regulations of the U.S. Securities and Exchange Commission ("SEC") regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Accordingly, these unaudited interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements contained in the Annual Report. The unaudited condensed consolidated balance sheet as of December 31, 2021 included herein was derived from the audited consolidated financial statements as of that date, but does not include all disclosures required by GAAP, including certain notes to the financial statements. The unaudited interim condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements. Certain prior period amounts have been reclassified to conform to the current period presentation, including reclassifying amortization of deferred costs to a separate line item within the condensed consolidated statement of cash flows. In the opinion of management, the accompanying unaudited condensed consolidated financial statements include all adjustments of a normally recurring nature necessary for the fair presentation of the interim periods presented. Principles of Consolidation These unaudited interim condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated upon consolidation. Use of Estimates The preparation of the Company’s unaudited interim condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of income and expenses during the reporting period. These estimates are based on information available as of the date of the condensed consolidated financial statements; therefore, actual results could differ from management’s estimates due to the uncertainty of the extent of the impacts of macroeconomic conditions and other factors. Significant Accounting Policies There have been no material changes to the Company's significant accounting policies from those described in the Annual Report.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS The Company’s investments in money market accounts are recorded as cash equivalents at fair value on the condensed consolidated balance sheets. 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 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 June 30, 2022 and December 31, 2021 (in thousands): June 30, 2022 December 31, 2021 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Cash equivalents: Money market funds $ 391,015 $ — $ — $ 391,015 $ 390,376 $ — $ — $ 390,376 Other investments: Certificates of deposit — 10,000 — 10,000 — 10,000 — 10,000 Total cash equivalents and other investments $ 391,015 $ 10,000 $ — $ 401,015 $ 390,376 $ 10,000 $ — $ 400,376 The certificates of deposit are reflected in prepaid expenses and other current assets on the condensed consolidated balance sheets as of June 30, 2022 and December 31, 2021.

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 as of August 31, 2021 and concluded that goodwill was not impaired, as the fair value of the reporting unit exceeded its carrying value. The changes in carrying amount of goodwill during the six months ended June 30, 2022 were as follows (in thousands): Balance as of December 31, 2021 $ 105,128 Effect of currency translation (3,602) Balance as of June 30, 2022 $ 101,526 Intangible assets that were not fully amortized as of June 30, 2022 and December 31, 2021 consisted of the following (dollars in thousands): June 30, 2022 Gross Carrying Amount Accumulated Amortization Net Carrying Amount Weighted Average Remaining Life Business relationships $ 9,918 $ (5,196) $ 4,722 6.7 years Developed technology 7,709 (7,709) — 0.0 years Licensing agreements 6,129 (1,183) 4,946 7.7 years Domains and data licenses 2,869 (2,858) 11 1.0 years Total $ 26,625 $ (16,946) $ 9,679 December 31, 2021 Gross Carrying Amount Accumulated Amortization Net Carrying Amount Weighted Average Remaining Life 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 was $0.3 million and $0.7 million for the three months ended June 30, 2022 and 2021, respectively, and $1.0 million and $1.4 million for the six months ended June 30, 2022 and 2021, respectively.

The net decrease in the allowance for doubtful accounts in the six months ended June 30, 2021 was primarily a result of a reduction in expected customer delinquencies as collection rates improved. In calculating the allowance for doubtful accounts as of June 30, 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 condensed 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 deferred revenue during the six months ended June 30, 2022 were as follows (in thousands): Six Months Ended Balance, beginning of period $ 4,156 Less: recognition of deferred revenue from beginning balance (3,508) Add: net increase in current period contract liabilities 5,493 Balance, end of period $ 6,141 The majority of the deferred revenue balance as of June 30, 2022 is expected to be recognized as revenue in the subsequent three-month period ending September 30, 2022. An immaterial amount of long-term deferred revenue is included in other long-term liabilities as of June 30, 2022. No other contract assets or liabilities were recorded on the Company's condensed consolidated balance sheets as of June 30, 2022 and December 31, 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 (the "Court"), naming as defendants the Company and certain of its officers (the “Securities Class Action”). The complaint, which the plaintiff amended on June 25, 2018, alleges 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 seeks 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, which the Company expects to be funded by defendants’ insurers. The proposed settlement, which was preliminarily approved by the Court on July 25, 2022, will resolve all claims asserted against all defendants in the Securities Class Action without any liability or wrongdoing attributed to them. On June 22, 2022, the Court granted preliminary 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 is also pending before the Court. The proposed settlement will resolve 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 proposed settlement, the Company’s board of directors will adopt and implement certain corporate governance modifications and the Company will receive $18.0 million of insurance proceeds. Subsequent to the quarter end, the proceeds were placed in escrow in July 2022 pending final approval of the settlement. The Company has agreed to pay $3.75 million of such insurance proceeds to the plaintiff’s attorneys as fees. 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. Although final approval of the settlement agreements for the Securities Class Action and the Derivative Action remains pending, the Company believes the loss for both are probable and the payment amounts described above, which total $26.0 million, represent reasonable estimates of loss contingencies. The Company also believes that the anticipated insurance proceeds related to each action described above, which also total $26.0 million, are probable and represent 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 on its condensed consolidated balance sheets as of June 30, 2022 and December 31, 2021. 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 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 will 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 business, 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. As of June 30, 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 June 30, 2022. For additional information on the terms of the Credit Agreement, including fees payable by the Company, financial covenants, events of default and other limitations, see " Management's Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources " included under Part II, Item 7 in our Annual Report.

The Company may purchase shares at management’s discretion in the open market, in privately negotiated transactions, in transactions structured through investment banking institutions, or a combination of the foregoing. During the six months ended June 30, 2022, the Company repurchased on the open market 3,039,203 shares for an aggregate purchase price of $100.0 million and retired 2,932,305 shares. As of June 30, 2022, the Company had a treasury stock balance of 106,898 shares, which were excluded from its outstanding share count as of such date and subsequently retired in July 2022. During the six months ended June 30, 2021, the Company repurchased on the open market 3,019,987 shares for an aggregate purchase price of $114.2 million and retired 3,015,135 shares. As of June 30, 2021, the Company had a treasury stock balance of 103,870 shares, which were excluded from its outstanding share count as of such date and subsequently retired in July 2021. Equity Incentive Plans Stock Options Stock options 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. A summary of stock option activity for the six months ended June 30, 2022 is as follows: Number of Shares (in thousands) Weighted-Average Exercise Price Weighted-Average Remaining Contractual Term (in years) Aggregate Intrinsic Value (in thousands) Outstanding at December 31, 2021 3,979 $ 32.59 4.4 $ 24,580 Granted 10 31.42 Exercised (88) 21.80 Canceled (20) 36.86 Outstanding at June 30, 2022 3,881 $ 32.82 3.8 $ 9,017 Options vested and exercisable at June 30, 2022 3,673 $ 32.69 3.5 $ 9,017 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 $0.6 million and $0.7 million for the three months ended June 30, 2022 and 2021, respectively, and $0.9 million and $11.8 million for the six months ended June 30, 2022 and 2021, respectively. The weighted-average grant date fair value of options granted during the three and six months ended June 30, 2022 was $16.07 per share. The weighted-average grant date fair value of options granted during the three and six months ended June 30, 2021 was $18.55 per share. As of June 30, 2022, total unrecognized compensation costs related to nonvested stock options were approximately $3.1 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 performance-based restricted stock units ("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 equals or exceeds $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. The shares underlying each PRSU award 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 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 year following the year in which the PRSUs are granted. 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 June 30, 2022 to assess the probability of achievement of the PRSU financial targets and, as a result, recorded compensation costs in the three and six months ended June 30, 2022 for the PRSUs that it expected to vest. As the PRSU activity during the six months ended June 30, 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 six months ended June 30, 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 5,489 35.62 Vested (1) (2,543) 33.62 Canceled (1,395) 33.21 Nonvested at June 30, 2022 11,567 $ 33.55 (1) Includes 1,007,743 shares that vested but were not issued due to net share settlement for payment of employee taxes. The aggregate fair value as of the vest date of RSUs and PRSUs that vested during the six months ended June 30, 2022 and 2021 was $81.4 million and $88.7 million, respectively. As of June 30, 2022, the Company had approximately $363.8 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 2.7 years. Employee Stock Purchase Plan The Employee Stock Purchase Plan ("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 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. There were 364,436 shares purchased by employees under the ESPP at a weighted-average price of $25.00 in the three and six months ended June 30, 2022. There were 254,449 shares purchased by employees under the ESPP at a weighted-average price of $34.09 in the three and six months ended June 30, 2021. The Company recognized stock-based compensation expense related to the ESPP of $0.7 million in each of the three months ended June 30, 2022 and 2021 and $1.5 million in each of the six months ended June 30, 2022 and 2021.

INCOME TAXES

INCOME TAXES	6 Months Ended

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The Company is subject to income taxes in the United States as well as other tax jurisdictions in which it conducts business. Earnings from non-U.S. activities are subject to local country income taxes. The provision for income taxes for the six months ended June 30, 2022 was $6.7 million, which was due to $6.8 million of U.S. federal, state and foreign income tax expense and $0.1 million of net discrete tax benefit primarily related to stock-based compensation. The benefit from income taxes for the six months ended June 30, 2021 was $6.9 million, which was due to $1.5 million of U.S. federal, state and foreign income tax benefit and $5.4 million of net discrete tax benefit primarily related to stock-based compensation. Accounting for income taxes for interim periods generally requires the provision for income taxes to be determined by applying an estimate of the annual effective tax rate for the full fiscal year to income or loss before income taxes, excluding unusual or infrequently occurring discrete items, for the reporting period. For the three and six months ended June 30, 2022, the difference between the effective tax rate and the federal statutory tax rate primarily related to stock-based compensation and the inclusion of global intangible low-taxed income ("GILTI"), offset by tax credits. As currently enacted, beginning in 2022, the Tax Cuts and Jobs Act (the "Tax Act") requires taxpayers to capitalize research and development expenses with amortization periods over five and fifteen years, which is expected to increase the amount of the Company's GILTI. For the three and six months ended June 30, 2021, the difference between the effective tax rate and the federal statutory tax rate primarily related to tax credits, offset by non-deductible expenses. As of June 30, 2022, the total amount of gross unrecognized tax benefits was $57.5 million, $29.3 million of which was subject to a full valuation allowance and would not affect the Company’s effective tax rate if recognized. In the three and six months ended June 30, 2022, the Company recorded an immaterial amount of interest and penalties. As of June 30, 2022, the Company estimated that it had accumulated undistributed earnings generated by its foreign subsidiaries of approximately $12.9 million. Any taxes due with respect to such earnings or the excess of the amount for financial reporting over the tax basis of the Company's foreign investments would generally be limited to foreign and state taxes. The Company has not recognized a deferred tax liability related to unremitted foreign earnings, as it intends to indefinitely reinvest these earnings, and expects future U.S. cash generation to be sufficient to meet future U.S. cash needs. In addition, the Company is subject to the continuous examination of its income tax returns by the Internal Revenue Service and other tax authorities. The Company’s federal and state income tax returns for tax years subsequent to 2003 remain open to examination. In the Company’s foreign jurisdictions — Canada, Germany, Ireland and the United Kingdom — the tax years subsequent to 2016 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. As of June 30, 2022, although the timing of the resolution or closure of audits is not certain, the Company believes it is reasonably possible that its unrecognized tax benefits could be reduced by $0.9 million over the next 12 months.

Earnings Per Share [Abstract]
NET INCOME (LOSS) PER SHARE	NET INCOME (LOSS) PER SHARE Basic net income (loss) per share is computed using the weighted-average number of outstanding shares of common stock during the period. Diluted net income (loss) per share is computed using the weighted-average number of outstanding shares of common stock and, when dilutive, potential shares of common stock outstanding during the period. Potential common shares consist of the incremental shares of common stock issuable upon the exercise of stock options, shares issuable upon the vesting of RSUs (including PRSUs) and, to a lesser extent, purchase rights related to the ESPP. The following table presents the calculation of basic and diluted net income (loss) per share for the periods presented (in thousands, except per share data): Three Months Ended Six Months Ended 2022 2021 2022 2021 Basic net income (loss) per share: Net income (loss) $ 8,009 $ 4,212 $ 7,094 $ (1,584) Shares used in computation: Weighted-average common shares outstanding 71,217 74,807 71,427 75,025 Basic net income (loss) per share attributable to common stockholders $ 0.11 $ 0.06 $ 0.10 $ (0.02) Three Months Ended Six Months Ended 2022 2021 2022 2021 Diluted net income (loss) per share: Net income (loss) $ 8,009 $ 4,212 $ 7,094 $ (1,584) Shares used in computation: Weighted-average common shares outstanding 71,217 74,807 71,427 75,025 Stock options 445 877 505 — RSUs 1,163 3,291 1,635 — ESPP 10 8 5 — Number of shares used in diluted calculation 72,835 78,983 73,572 75,025 Diluted net income (loss) per share attributable to common stockholders $ 0.11 $ 0.05 $ 0.10 $ (0.02) The following stock-based instruments were excluded from the calculation of diluted net income (loss) per share because their effect would have been anti-dilutive for the periods presented (in thousands): Three Months Ended Six Months Ended 2022 2021 2022 2021 Stock options 2,444 1,497 2,447 4,109 RSUs 7,958 145 6,734 10,998 ESPP — — — 41

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): Three Months Ended Six Months Ended 2022 2021 2022 2021 Net revenue by product: Advertising revenue by category (1) : Services $ 174,298 $ 152,522 $ 334,561 $ 293,209 Restaurants, Retail & Other 109,220 92,439 212,194 173,739 Advertising 283,518 244,961 546,755 466,948 Transactions 3,940 3,525 7,120 7,329 Other 11,426 8,702 21,637 15,007 Total net revenue $ 298,884 $ 257,188 $ 575,512 $ 489,284 (1) Advertising revenue by category in 2022 reflects an updated method of disaggregation. Prior-period amounts have not been updated as it is impracticable to do so, given certain historical information was not available. During the three and six months ended June 30, 2022 and 2021, 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 revenue is recognized, 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 $0.1 million and $0.7 million during the three months ended June 30, 2022 and 2021, respectively, and $0.4 million and $2.9 million during the six months ended June 30, 2022 and 2021, respectively. These incentives were primarily in the form of waived subscription and advertising fees. The Company accounted for these incentives as price concessions and reduced net revenue recognized in the three and six months ended June 30, 2022 and 2021 accordingly. The following table presents the Company’s net revenue by major geographic region for the periods presented (in thousands): Three Months Ended Six Months Ended 2022 2021 2022 2021 United States $ 296,876 $ 254,954 $ 571,520 $ 484,949 All other countries 2,008 2,234 3,992 4,335 Total net revenue $ 298,884 $ 257,188 $ 575,512 $ 489,284 Long-Lived Assets The following table presents the Company’s long-lived assets by major geographic region for the periods presented (in thousands): June 30, December 31, United States $ 77,367 $ 79,027 All other countries 4,845 4,830 Total long-lived assets $ 82,212 $ 83,857

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying interim condensed consolidated financial statements are unaudited. These unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") and the applicable rules and regulations of the U.S. Securities and Exchange Commission ("SEC") regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Accordingly, these unaudited interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements contained in the Annual Report. The unaudited condensed consolidated balance sheet as of December 31, 2021 included herein was derived from the audited consolidated financial statements as of that date, but does not include all disclosures required by GAAP, including certain notes to the financial statements. The unaudited interim condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements. Certain prior period amounts have been reclassified to conform to the current period presentation, including reclassifying amortization of deferred costs to a separate line item within the condensed consolidated statement of cash flows. In the opinion of management, the accompanying unaudited condensed consolidated financial statements include all adjustments of a normally recurring nature necessary for the fair presentation of the interim periods presented.
Principles of Consolidation	Principles of Consolidation These unaudited interim condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated upon consolidation.
Use of Estimates	Use of Estimates The preparation of the Company’s unaudited interim condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of income and expenses during the reporting period. These estimates are based on information available as of the date of the condensed consolidated financial statements; therefore, actual results could differ from management’s estimates due to the uncertainty of the extent of the impacts of macroeconomic conditions and other factors.
