For the six months ended June 30, 2023, the interest expense and amortization of note costs relating to the shares issuable upon conversion of our outstanding convertible notes were excluded from the calculation as they would have been anti-dilutive.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies The accompanying condensed consolidated financial statements reflect the application of certain significant accounting policies as described below and elsewhere in these notes to condensed consolidated financial statements. The Company’s critical accounting policies are those that affect its more significant judgments used in the preparation of its condensed consolidated financial statements. A description of the Company’s critical accounting policies and estimates is contained in its Annual Report on Form 10-K for the fiscal year ended December 31, 2022, and in this note to the condensed consolidated financial statements. Principles of Consolidation The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, TechTarget Securities Corporation (“TSC”), TechTarget Limited, TechTarget (HK) Limited (“TTGT HK”), TechTarget (Australia) Pty Ltd., TechTarget (Singapore) Pte Ltd., E-Magine Médias SAS (“LeMagIT”), TechTarget Germany GmbH, and BrightTALK Limited and its wholly owned subsidiary, BrightTALK, Inc. (together “BrightTALK”). TSC is a Massachusetts corporation. TechTarget Limited is a subsidiary doing business principally in the United Kingdom. TTGT HK is a subsidiary incorporated in Hong Kong in order to facilitate the Company’s activities in the Asia-Pacific region. TechTarget (Australia) Pty Ltd. and TechTarget (Singapore) Pte Ltd. are the entities through which the Company does business in Australia and Singapore, respectively; LeMagIT and TechTarget Germany GmbH, both wholly-owned subsidiaries of TechTarget Limited, are entities through which the Company does business in France and Germany, respectively. BrightTALK are the entities through which the Company conducts business related to its BrightTALK webinar and virtual event platform. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted (Generally Accepted Accounting Principles or “U.S. GAAP”) in the United States (“U.S.”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. All adjustments, which, in the opinion of management, are considered necessary for a fair presentation of the results of operations for the periods shown, are of a normal, recurring nature and have been reflected in the condensed consolidated financial statements. The results of operations for the periods presented are not necessarily indicative of results to be expected for any other interim periods or for the full year. The information included in these condensed consolidated financial statements should be read in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations” contained in this report and the condensed consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022 . Forei gn Currency Translation The functional currency of the Company’s major foreign subsidiaries is generally the local currency. Adjustments resulting from translating foreign functional currency financial statements into U.S. dollars are recorded as a separate component on the Condensed Consolidated Statement of Comprehensive Income as an element of accumulated other comprehensive income (loss). Foreign currency transaction gains and losses are included in interest and other income (expense), net in the Condensed Consolidated Statement of Income. All assets and liabilities denominated in foreign currency are translated into U.S. dollars at the exchange rate on the balance sheet date. Revenue and expenses are translated at the average exchange rate during the period. Use of Estimate s The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. On an ongoing basis, the Company evaluates its estimates, including those related to revenue, long-lived assets, goodwill, the allowance for doubtful accounts, stock-based compensation, earnouts, self-insurance accruals, the allocation of purchase price to intangibles and goodwill, and income taxes. The Company reduces its accounts receivable for an allowance for doubtful accounts based on its best estimate of the amount of probable credit losses. Estimates of the carrying value of certain assets and liabilities are based on historical experience and on various other assumptions that the Company believes to be reasonable. Actual results could differ from those estimates. Revenue Recognition The Company generates its revenue from the sale of targeted marketing and advertising campaigns, which it delivers via its network of websites, webinar and virtual events channels, and our data analytic services and solutions. Revenue is recognized when performance obligations are satisfied by transferring promised goods or services to customers, as determined by applying a five-step process consisting of: a) identifying the contract, or contracts, with a customer, b) identifying the performance obligations in the contract, c) determining the transaction price, d) allocating the transaction price to the performance obligations in the contract, and e) recognizing revenue when, or as, performance obligations are satisfied. Cash and Cash Equivalents The Company considers all highly liquid investments with original or remaining maturities of three months or less on the purchase date to be cash equivalents. Cash and cash equivalents carrying value approximate fair value and consist primarily of bank deposits and government backed money market funds. Accounts Receivable We maintain an allowance for credit losses for expected uncollectible accounts receivable, which is recorded as an offset to accounts receivable and changes in such are classified as general and administrative expense in the Condensed Consolidated Statements of Income and Comprehensive Income. We assess collectability by reviewing accounts receivable on an individual basis when we identify specific customers with known disputes, overdue amounts or collectability issues and also reserve for losses on all accounts based on historical information, current market conditions and reasonable and supportable forecasts of future economic conditions to inform adjustments to historical loss data. In determining the amount of the allowance for credit losses, we consider historical collectability based on past due status and make judgments about the creditworthiness of customers based on ongoing credit evaluations. At June 30, 2023 , the Company’s collectability assessment includes the business and market disruptions caused by macro-economic uncertainty currently being experienced in the technology sector and estimates of expected emerging credit and collectability trends. The continued volatility in market conditions and evolving shifts in credit trends are difficult to predict, causing variability and volatility that may have a material impact on our allowance for credit losses in future periods. Fair Value of Financial Instruments Financial instruments consist of cash and cash equivalents, short-term investments, accounts receivable, accounts payable, long-term debt and contingent consideration. Due to their short-term nature and liquidity, the carrying value of these instruments, with the exception of contingent consideration and long-term debt, approximates their estimated fair values. The Company classifies all of its short-term and long-term investments in debt securities as available-for-sale. The fair value of contingent consideration was estimated using a discounted cash flow method. Business Combinations and Valuation of Goodwill and Acquired Intangible Assets The Company uses its best estimates and assumptions to allocate fair value to the net tangible and identifiable intangible assets acquired and liabilities assumed at the acquisition date. Any residual purchase price is recorded as goodwill. The Company’s estimates are inherently uncertain and subject to refinement and can include but are not limited to, the cash flows that an asset is expected to generate in the future, and the appropriate weighted-average cost of capital. During the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the fair value of these tangible and intangible assets acquired and liabilities assumed, with the corresponding offset to goodwill. In addition, uncertain tax positions and tax-related valuation allowances are initially recorded in connection with a business combination as of the acquisition date. The Company continues to collect information and reevaluates these estimates and assumptions quarterly and records any adjustments to the Company’s preliminary estimates to goodwill provided that the Company is within the measurement period. Upon the conclusion of the measurement period or final determination of the fair value of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the Company’s Condensed Consolidated Statement of Income and Comprehensive Income. Recen t Accounting Pronouncements Recently Adopted Accounting Guidance In October 2021, the FASB issued ASU 2021-08, “Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers,” which requires entities to apply Topic 606 to recognize and measure contract assets and contract liabilities in a business combination as if it had originated the contracts. The standard is effective for public companies for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022. Early adoption is permitted. We adopted the new standard effective January 1, 2023 and the guidance did not have a material impact on our consolidated financial statements.

Liabilities are recorded for amounts that are collected in advance of the satisfaction of performance obligations. Additionally, certain customers may receive credits, which are accounted for as a material right. The Company estimates these amounts based on the expected amount of future services to be provided to the customer and allocates a portion of the transaction price to these material rights. The Company recognizes these material rights as the material rights are exercised. The resulting material rights amounts included in the contract liabilities on the accompanying Condensed Consolidated Balance Sheets was $ 2.1 million and $ 1.9 million at June 30, 2023, and December 31, 2022, respectively. Contract Liabilities Year-to-Date Activity Balance at December 31, 2022 $ 27,086 Billings 52,378 Revenue Recognized ( 57,114 ) Balance at March 31, 2023 $ 22,350 Billings 56,656 Revenue Recognized ( 58,429 ) Balance at June 30, 2023 $ 20,577 The Company elected to apply the following practical expedients: • Existence of a Significant Financing Component in a Contract . As a practical expedient, the Company has not assessed whether a contract has a significant financing component because the Company expects at contract inception that the period between payment by the customer and the transfer of promised goods or services by the Company to the customer will be one year or less. Payment terms and conditions vary by contract type, although terms generally include a requirement of payment within 30 to 90 days. In addition, the Company has determined that the payment terms that the Company provides to its customers are structured primarily for reasons other than the provision of financing to the customer. • Costs to Fulfill a Contract . The Company’s revenue is primarily generated from customer contracts that are for one year or less. Costs primarily consist of incentive compensation paid based on the achievement of sales targets. As a practical expedient, for amortization periods that are determined to be one year or less, the Company expenses any incremental costs of obtaining the contract with a customer when incurred. For those customer contracts greater than one year, the Company capitalizes and amortizes the expenses over the period of benefit. • Revenue Invoiced . The Company has applied the practical expedient for certain revenue streams to exclude the value of remaining performance obligations for (i) contracts with an original expected term of one year or less or (ii) contracts for which the Company recognizes revenue in proportion to the amount it has the right to invoice for services performed.

Fair Value Disclosures [Abstract]
Fair Value Measurements	4. Fair Value Measurements The Company measures certain financial assets and liabilities at fair value on a recurring basis, including short-term and long-term investments and contingent consideration. The Company’s bank and money market accounts are in bank deposits and are not quoted instruments. As such, the Company’s bank and money market accounts are all considered cash. The fair value of these financial assets and liabilities was determined based on three levels of input as follows: • Level 1. Quoted prices in active markets for identical assets and liabilities; • Level 2. Observable inputs other than quoted prices in active markets; and • Level 3. Unobservable inputs. The fair value hierarchy of the Company’s financial assets carried at fair value and measured on a recurring basis is as follows: Fair Value Measurements at June 30, 2023 Quoted Prices Significant Significant Assets: Time deposits (1) $ 25,245 $ — $ 25,245 $ — Pooled bond funds 71,034 — 71,034 — Total short-term investments $ 96,279 $ — $ 96,279 $ — Fair Value Measurements at December 31, 2022 Quoted Prices Significant Significant Assets: Pooled bond funds $ 20,210 $ — $ 20,210 $ — Total short-term investments $ 20,210 $ — $ 20,210 $ — Liabilities: Contingent consideration - current (2) $ 2,259 $ — $ — $ 2,259 Total liabilities $ 2,259 $ — $ — $ 2,259 (1) The Company's time deposits consist of domestic deposits which mature within nine months (Level 2). Level 2 investments are priced using observable inputs, such as quoted prices in markets that are not active and yield curves. (2) Contingent consideration liabilities are measured using the income approach and discounted to present value based on an assessment of the probability that the Company would be required to make such future payments. The contingent consideration liabilities are measured at fair value using significant Level 3 (unobservable) inputs, such as discount rates and probability measures. Remeasurement of the contingent consideration to fair value is expensed through the income statement in the period remeasured. Contingent consideration–current is included in accrued expenses and other current liabilities on the balance sheet. The follow ing table provides a roll-forward of the fair value of the contingent consideration for the six months ended June 30, 2023: Fair Value Year-to-Date Activity Balance at December 31, 2022 $ 2,259 Payments on contingent liabilities ( 2,267 ) Amortization of discount on contingent liabilities 8 Balance at March 31, 2023 $ — As of June 30, 2023 , the Company has no contingent consideration amounts remaining.

Goodwill and Intangible Assets	6. Goodwill and Intangible Assets Goodwill and indefinite-lived intangible assets are not amortized but are reviewed annually for impairment or more frequently if impairment indicators arise. The Company did no t have any intangible assets with indefinite lives other than goodwill as of June 30, 2023 or December 31, 2022 . There were no indications of impairment as of June 30, 2023, and the Company believes that, as of the balance sheet dates presented, none of the Company’s goodwill or intangible assets were impaired.

The remaining amortization expense will be recognized over a weighted-average period of approximately 6.6 years. Amortization expense was $ 4.4 million and $ 4.6 million for the six months ended June 30, 2023 and 2022 , respectively. Amortization expense relating to developed websites, technology and patents is recorded within costs of revenues. All other amortization is recorded within operating expenses as the remaining intangible assets consist of customer-related assets which generate website traffic that the Company considers to be in support of selling and marketing activities. The Company did no t write off any fully amortized intangible assets in the first six months of 2023. The Company expects amortization expense of intangible assets to be as follows: Years Ending December 31: Amortization 2023 (July 1 – December 31) $ 4,409 2024 8,795 2025 8,756 2026 8,702 2027 8,698 Thereafter 53,860 Total $ 93,220

Additionally, in calculating diluted net income per share, we excluded the impact of interest expense and amortization of note costs relating to the shares issuable upon conversion of our outstanding convertible notes from net income and included the weighted average of 3.9 million common shares under the if-converted method for each of the three and six months ended June 30, 2023 and for each of the three and six months ended June 30, 2022, respectively. The interest expense including amortization of note issuance costs, related to convertible notes was $ 0.6 million for each of the three months ended June 30, 2023 and June 30 2022, and $ 1.3 million for the six months ended June 30, 2022 . For the six months ended June 30, 2023, the interest expense and amortization of note costs relating to the shares issuable upon conversion of our outstanding convertible notes were excluded from the calculation as they would have been anti-dilutive.

Convertible Notes and Loan Agreement Convertible Notes In December 2020, the Company issued $ 201.3 million in aggregate principal amount of 0.125 % convertible senior notes due December 15, 2025 (the “2025 Notes”) and in December 2021, the Company issued $ 414 million in aggregate principal amount of 0.0 % convertible senior notes due December 15, 2026 (the “2026 Notes”). At the time of the issuance of the 2026 Notes, a portion of the outstanding 2025 Notes were exchanged for shares of common stock and cash. As of June 30, 2023 , approximately $ 51 million aggregate principal amount of the 2025 Notes remain outstanding. Further details are included below: Issuance Maturity Date Interest Rate First Interest Payment Date Effective Interest Rate Semi-Annual Interest Payment Dates Initial Conversion Rate per $1,000 Principal Initial Conversion Price Number of Shares (in millions) 2025 Notes December 15, 2025 0.125 % June 15, 2021 0.8 % June 15, and December 15 14.1977 $ 70.43 1.0 2026 Notes December 15, 2026 0.0 % –– 0.0 % –– 7.6043 $ 131.50 4.3 Each of the 2025 Notes and the 2026 Notes (collectively, the “Notes”) is governed by an indenture between the Company, as issuer, and U.S. Bank, National Association, as trustee (together the “Indentures”, and each such indenture, an “Indenture”). The Notes are unsecured and rank senior in right of payment to the Company’s future indebtedness that is expressly subordinated in right of payment to the Notes and equal in right of payment to the Company’s unsecured indebtedness that is not so subordinated. Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of the Company’s common stock or a combination of cash and shares of common stock, at the Company’s election. Terms of the Notes Prior to the close of business on September 15, 2025 and September 14, 2026, the 2025 Notes and 2026 Notes, respectively, will be convertible at the option of holders during certain periods, only upon satisfaction of certain conditions set forth below. On or after September 15, 2025 (for the 2025 Notes) and September 14, 2026 (for the 2026 Notes), until the close of business on the second scheduled trading day immediately preceding the applicable maturity date, holders may convert all or any portion of their Notes at the applicable conversion price at any time regardless of whether the conditions set forth below have been met. Holders may convert all or a portion of their Notes prior to the close of business on the day immediately preceding their respective free convertibility date described above, in multiples of the $ 1,000 principal amount, only under the following circumstances : • during any calendar quarter commencing after the calendar quarter ending on March 31, 2021 for the 2025 Notes and March 31, 2022 for the 2026 Notes (and only during such calendar quarter), if the last reported sales price of the common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130 % of the applicable conversion price on each applicable trading day; • during the five business day period after any five consecutive trading day period, or the Notes measurement period, in which the “trading price” (as defined in each Indenture) per $ 1,000 principal amount of Notes for each trading day of the Notes measurement period was less than 98 % of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such trading day; • if the Company calls any or all of the Notes for redemption, at any time prior to the close of business on September 14, 2025 for the 2025 Notes or September 14, 2026 for the 2026 Notes; or • upon the occurrence of specified corporate events as set forth in the Indentures. As of June 30, 2023, the 2026 Notes and 2025 Notes are not convertible. Whether the 2026 Notes or the 2025 Notes will be convertible in the future prior to the applicable free convertibility date will depend on the satisfaction of the trading price condition or another conversion condition specified in the Indentures. Since the Company may elect to repay the 2026 Notes and the 2025 Notes in cash, shares of our common stock, or a combination of both, the Company has continued to classify the 2026 and the 2025 Notes as long-term debt on its consolidated balance sheet as of June 30, 2023.

Leases and Contingencies	9. Leases and Contingencies The Company conducts its operations in leased office facilities under various noncancelable operating lease agreements that expire through December 2029. On October 26, 2017, the Company entered into a Third Amendment (the “Third Amendment”) to the lease agreement for office space in Newton, Massachusetts, dated as of August 4, 2009 (the “Newton Lease”). The Third Amendment extended the lease term to December 31, 2029 and preserves the Company’s option to extend the term for an additional five-year period subject to certain terms and conditions set forth in the Newton Lease. The Third Amendment reduced the rentable space from approximately 110,000 square feet to approximately 74,000 square feet effective January 1, 2018 . As of January 1, 2018, base monthly rent under the Third Amendment is $ 0.3 million. The base rent increases biennially at a rate averaging approximately 1 % per year, as of January 1, 2022. The Company remains responsible for certain other costs under the Third Amendment, including operating expense and taxes. In April 2021, the Company entered into a Fourth Amendment (the “Fourth Amendment”). The Fourth Amendment became effective during May 2021 . The Fourth Amendment reduced the rentable space from approximately 74,000 square feet to approximately 68,000 square feet and provided the Company with a one-time payment of approximately $ 0.6 million. As of May 1, 2021, base monthly rent is approximately $ 0.3 million per month. All other terms and conditions are substantially similar to those terms in the Third Amendment. Certain of the Company’s operating leases, including the Newton Lease, include lease incentives and escalating payment amounts and are renewable for varying periods. The Company recognizes the related rent expense on a straight-line basis over the term of each lease, taking into account the lease incentives and escalating lease payments. The Company has various non-cancelable lease agreements for certain of its offices with original lease periods expiring between 2024 and 2029. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain it will exercise that option. Leases with renewal options allow the Company to extend the lease term typically between 1 and 5 years . When determining the lease term, renewal options reasonably certain of being exercised are included in the lease term. When determining if a renewal option is reasonably certain of being exercised, the Company considers several economic factors, including but not limited to, the significance of leasehold improvements incurred on the property, whether the asset is difficult to replace, underlying contractual obligations, or specific characteristics unique to that particular lease that would make it reasonably certain that the Company would exercise such option. Renewal and termination options were generally not included in the lease term for the Company's existing operating leases. Certain of the arrangements have discounted rent periods or escalating rent payment provisions. Leases with an initial term of twelve months or less are not recorded on the condensed consolidated balance sheets. The Company recognizes rent expense on a straight-line basis over the lease term. As of June 30, 2023, operating lease assets were $ 18.7 million and operating lease liabilities were $ 22.5 million. The maturities of the Company’s operating lease liabilities as of June 30, 2023 were as follows: Minimum Lease Years Ending December 31: Payments 2023 (July 1 – December 31) $ 2,450 2024 4,989 2025 4,071 2026 3,904 2027 3,348 Thereafter 6,735 Total future minimum lease payments 25,497 Less imputed interest 2,999 Total operating lease liabilities $ 22,498 Included in the Consolidated Balance Sheet: Current operating lease liability $ 3,968 Non-current operating lease liability 18,530 Total operating lease liabilities $ 22,498 For the three and six months ended June 30, 2023 and 2022, the total lease cost was comprised of the following amounts: Three Months Ended Six Months Ended 2023 2022 2023 2022 Operating lease expense $ 1,048 $ 712 $ 2,104 $ 1,853 Short-term lease expense 5 2 9 11 Total lease expense $ 1,053 $ 714 $ 2,113 $ 1,864 The following summarizes additional information related to operating leases as of June 30, 2023: As of June 30, 2023 Weighted-average remaining lease term — operating leases 3.5 Weighted-average discount rate — operating leases 3.4 % If the rate implicit in the lease is not readily determinable, the Company uses its incremental borrowing rate as the discount rate. The Company uses its best judgment when determining the incremental borrowing rate, which is the rate of interest that the Company would have to pay to borrow on a collateralized basis over a similar term to the lease payments in a similar currency. Litigation From time to time and in the ordinary course of business, the Company may be subject to various claims, charges, and litigation. At June 30, 2023 and December 31, 2022 , the Company did no t have any pending or threatened claims, charges, or litigation that it expects would have a material adverse effect on its condensed consolidated financial position, results of operations, or cash flows.

Share-Based Payment Arrangement [Abstract]
Stock-Based Compensation	10. Stock-Based Compensation Stock Option and Incentive Plans In April 2007, the Company’s board of directors approved the 2007 Stock Option and Incentive Plan (the “2007 Plan”), which was approved by the stockholders of the Company and became effective upon the consummation of the Company’s IPO in May 2007. The 2007 Plan allowed the Company to grant incentive stock options (“ISOs”), non-qualified stock options (“NSOs”), stock appreciation rights, deferred stock awards, restricted stock units and other awards. Under the 2007 Plan, stock options could not be granted at less than fair market value on the date of grant and grants generally vested over a three - to four-year period. Stock options granted under the 2007 Plan expire no later than ten years after the grant date. Additionally, beginning with awards made in August 2015, the Company had the option to direct a net issuance of shares for satisfaction of tax liability with respect to vesting of awards and delivery of shares. Prior to August 2015, this choice of settlement method was solely at the discretion of the award recipient. The 2007 Plan expired in May 2017 . No new awards may be granted under the 2007 Plan; however, the shares of common stock remaining in the 2007 Plan are available for issuance in connection with previously awarded grants under the 2007 Plan. There are 22,500 shares of common stock that remain subject to outstanding stock grants under the 2007 Plan as of June 30, 2023. In March 2017, the Company’s board of directors approved the 2017 Stock Option and Incentive Plan (the “2017 Plan”), which was approved by the stockholders of the Company at the 2017 Annual Meeting and became effective June 16, 2017 . The 2017 Plan replaces the Company’s 2007 Plan. On June 16, 2017, 3,000,000 shares of the Company’s common stock were reserved for issuance under the 2017 Plan and, generally, shares that are forfeited or canceled from awards under the 2017 Plan also will be available for future awards. In April 2021, the stockholders of the Company authorized the issuance of up to an additional 3,800,000 shares of the Company’s common stock under the 2017 Plan. Under the 2017 Plan, the Company may grant restricted stock and restricted stock units, non-qualified stock options, stock appreciation rights, performance awards, and other stock-based and cash-based awards. Grants generally vest in equal tranches over a three-year period. Stock options granted under the 2017 Plan expire no later than ten years after the grant date. Shares of stock issued pursuant to restricted stock awards are restricted in that they are not transferable until they vest. Shares of stock underlying awards of restricted stock units are not issued until the units vest. Non-qualified stock options cannot be exercised until they vest. Under the 2017 Plan, all stock options and stock appreciation rights must be granted with an exercise price that is at least equal to the fair market value of the common stock on the date of grant. The 2017 Plan broadly prohibits the repricing of options and stock appreciation rights without stockholder approval and requires that no dividends or dividend equivalents be paid with respect to options or stock appreciation rights. The 2017 Plan further provides that, in the event any dividends or dividend equivalents are declared with respect to restricted stock, restricted stock units, other stock-based awards and performance awards (referred to as “full-value awards”), such dividends or dividend equivalents would be subject to the same vesting and forfeiture provisions as the underlying award. There are a total of 1,878,398 shares of common stock that remain subject to outstanding stock-based grants under the 2017 Plan as of June 30, 2023 . A total of 2,113,315 shares of common stock remain available for issuance under the 2017 Plan as of June 30, 2023. Employee Stock Purchase Plan In April 2022, the Company’s board of directors approved the TechTarget, Inc. 2022 Employee Stock Purchase Plan (the “ESPP”), which was approved by the stockholders of the Company at the 2022 Annual Meeting of Stockholders and became effective June 7, 2022. On June 7, 2022, 600,000 shares of the Company’s common stock were reserved for issuance under the ESPP. After the initial offering period of three months, commencing September 1, 2022, eligible employees were offered shares of common stock over a twelve-month offering period, which consists of two consecutive six-month purchase periods. Employees may purchase a limited amount (up to $ 25,000 ) of shares of the Company’s common stock under the ESPP at a discount of up to 15 % of the lesser of the market value of the common stock at either (a) the beginning of the six-month purchase period during which the shares of common stock are purchased or (b) the end of such six-month purchase period. As of June 30, 2023 , 568,840 shares of common stock remain available for issuance under the ESPP. Accounting for Stock-Based Compensation The Company uses the Black-Scholes option pricing model to calculate the grant date fair value of an award. The expected volatility of options granted has been determined using a weighted average of the historical volatility of the Company’s common stock for a period equal to the expected life of the option. The expected life of options has been determined utilizing the “simplified” method. The risk-free interest rate is based on a zero coupon U.S. treasury instrument whose term is consistent with the expected life of the stock options. The Company has not paid and does not anticipate paying cash dividends on its shares of common stock; therefore, the expected dividend yield is assumed to be zero . The Company applied an estimated annual forfeiture rate based on historical averages in determining the expense recorded in each period. A summary of the stock option activity under the Company’s plans for the six months ended June 30, 2023 is presented below: Six Month Activity Options Weighted- Weighted- Aggregate (1) Options outstanding at December 31, 2022 120,000 $ 37.29 — — Granted 25,000 $ 36.46 — — Exercised ( 2,500 ) $ 7.03 — $ 81 Forfeited — — — — Cancelled — — — — Options outstanding at June 30, 2023 142,500 $ 37.68 6.74 $ 897 Options exercisable at June 30, 2023 117,500 $ 37.94 6.06 $ 897 Options vested or expected to vest at June 30, 2023 140,605 $ 37.69 6.69 $ 897 (1) The aggregate intrinsic value was calculated based on the positive difference between the fair value of the Company’s common stock on June 30, 2023 of $ 31.13 per share and the exercise price of the underlying options . The total intrinsic value of options exercised was $ 81 thousand and $ 0 during the six months ended June 30, 2023 and June 30, 2022 , respectively. The total amount of cash received from exercise of these options was approximately $ 18 thousand during the six months ended June 30, 2023 . There were no options exercised during the six months ended, June 30, 2022. Restricted Stock Units Restricted stock units are valued at the market price of a share of the Company’s common stock on the date of the grant. A summary of the restricted stock unit activity under the Company’s plans for the six months ended June 30, 2023 is presented below: Year-to-Date Activity Shares Weighted- Aggregate Nonvested outstanding at December 31, 2022 1,642,799 $ 62.40 — Granted 197,856 42.93 — Vested ( 69,007 ) 62.95 — Forfeited ( 13,250 ) 66.59 — Nonvested outstanding at June 30, 2023 1,758,398 $ 60.13 $ 54,739 There were 69,007 restricted stock units with a total grant-date fair value of $ 4.4 million that vested during the six months ended June 30, 2023 . There were 154,933 restricted stock units with a total grant-date fair value of $ 11.4 million that vested during the six months ended June 30, 2022. As of June 30, 2023 , there was $ 65.6 million of total unrecognized compensation expense related to stock options and restricted stock units, which is expected to be recognized over a weighted average period of 1.6 years. ESPP Valuation Assumptions The valuation of ESPP purchase rights and the underlying weighted-average assumptions are summarized as follows: June 30, 2023 ESPP: Expected term in years 0.50 Risk-free interest rate 5.27 % Expected volatility 43 % Expected dividend yield — % Weighted-average fair value per right granted $ 9.55

Income Tax Disclosure [Abstract]
Income Taxes	12. Income Taxes The Company measures its interim period tax expense using an estimated annual effective tax rate and adjustments for discrete taxable events that occur during the interim period. The estimated annual effective income tax rate is based upon the Company’s estimations of annual pre-tax income, the geographic mix of pre-tax income, and its interpretations of tax laws. The Company updates the estimate of its annual effective tax rate at the end of each quarterly period. The Company recorded income tax expense of $ 0.9 million and $ 2.3 million for the three and six months ended June 30, 2023, respectively. The tax expense for the three months ended June 30, 2023 decreased by approximately $ 4.8 million, as compared to the same period in 2022 , primarily due to a decrease in pretax income. The tax expense for the six months ended June 30, 2023 decreased by approximately $ 6.4 million primarily due to a decrease in pretax income that resulted in a $ 7.1 million decrease in tax expense based on the Company's projected effective tax rate offset by an increase of $ 0.7 million in tax from discrete items related to stock based compensation awards. The Company recorded income tax expense of $ 5.7 million and $ 8.7 million for the three and six months ended June 30, 2022, respectively.

Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted (Generally Accepted Accounting Principles or “U.S. GAAP”) in the United States (“U.S.”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. All adjustments, which, in the opinion of management, are considered necessary for a fair presentation of the results of operations for the periods shown, are of a normal, recurring nature and have been reflected in the condensed consolidated financial statements. The results of operations for the periods presented are not necessarily indicative of results to be expected for any other interim periods or for the full year. The information included in these condensed consolidated financial statements should be read in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations” contained in this report and the condensed consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022 .
Foreign Currency Translation	Forei gn Currency Translation The functional currency of the Company’s major foreign subsidiaries is generally the local currency. Adjustments resulting from translating foreign functional currency financial statements into U.S. dollars are recorded as a separate component on the Condensed Consolidated Statement of Comprehensive Income as an element of accumulated other comprehensive income (loss). Foreign currency transaction gains and losses are included in interest and other income (expense), net in the Condensed Consolidated Statement of Income. All assets and liabilities denominated in foreign currency are translated into U.S. dollars at the exchange rate on the balance sheet date. Revenue and expenses are translated at the average exchange rate during the period.
Use of Estimates	Use of Estimate s The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. On an ongoing basis, the Company evaluates its estimates, including those related to revenue, long-lived assets, goodwill, the allowance for doubtful accounts, stock-based compensation, earnouts, self-insurance accruals, the allocation of purchase price to intangibles and goodwill, and income taxes. The Company reduces its accounts receivable for an allowance for doubtful accounts based on its best estimate of the amount of probable credit losses. Estimates of the carrying value of certain assets and liabilities are based on historical experience and on various other assumptions that the Company believes to be reasonable. Actual results could differ from those estimates.
Revenue Recognition	Revenue Recognition The Company generates its revenue from the sale of targeted marketing and advertising campaigns, which it delivers via its network of websites, webinar and virtual events channels, and our data analytic services and solutions. Revenue is recognized when performance obligations are satisfied by transferring promised goods or services to customers, as determined by applying a five-step process consisting of: a) identifying the contract, or contracts, with a customer, b) identifying the performance obligations in the contract, c) determining the transaction price, d) allocating the transaction price to the performance obligations in the contract, and e) recognizing revenue when, or as, performance obligations are satisfied.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly liquid investments with original or remaining maturities of three months or less on the purchase date to be cash equivalents. Cash and cash equivalents carrying value approximate fair value and consist primarily of bank deposits and government backed money market funds.
Accounts Receivable	Accounts Receivable We maintain an allowance for credit losses for expected uncollectible accounts receivable, which is recorded as an offset to accounts receivable and changes in such are classified as general and administrative expense in the Condensed Consolidated Statements of Income and Comprehensive Income. We assess collectability by reviewing accounts receivable on an individual basis when we identify specific customers with known disputes, overdue amounts or collectability issues and also reserve for losses on all accounts based on historical information, current market conditions and reasonable and supportable forecasts of future economic conditions to inform adjustments to historical loss data. In determining the amount of the allowance for credit losses, we consider historical collectability based on past due status and make judgments about the creditworthiness of customers based on ongoing credit evaluations. At June 30, 2023 , the Company’s collectability assessment includes the business and market disruptions caused by macro-economic uncertainty currently being experienced in the technology sector and estimates of expected emerging credit and collectability trends. The continued volatility in market conditions and evolving shifts in credit trends are difficult to predict, causing variability and volatility that may have a material impact on our allowance for credit losses in future periods.
Fair Value of Financial Instruments	Fair Value of Financial Instruments Financial instruments consist of cash and cash equivalents, short-term investments, accounts receivable, accounts payable, long-term debt and contingent consideration. Due to their short-term nature and liquidity, the carrying value of these instruments, with the exception of contingent consideration and long-term debt, approximates their estimated fair values. The Company classifies all of its short-term and long-term investments in debt securities as available-for-sale. The fair value of contingent consideration was estimated using a discounted cash flow method.
Business Combinations and Valuation of Goodwill and Acquired Intangible Assets	Business Combinations and Valuation of Goodwill and Acquired Intangible Assets The Company uses its best estimates and assumptions to allocate fair value to the net tangible and identifiable intangible assets acquired and liabilities assumed at the acquisition date. Any residual purchase price is recorded as goodwill. The Company’s estimates are inherently uncertain and subject to refinement and can include but are not limited to, the cash flows that an asset is expected to generate in the future, and the appropriate weighted-average cost of capital. During the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the fair value of these tangible and intangible assets acquired and liabilities assumed, with the corresponding offset to goodwill. In addition, uncertain tax positions and tax-related valuation allowances are initially recorded in connection with a business combination as of the acquisition date. The Company continues to collect information and reevaluates these estimates and assumptions quarterly and records any adjustments to the Company’s preliminary estimates to goodwill provided that the Company is within the measurement period. Upon the conclusion of the measurement period or final determination of the fair value of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the Company’s Condensed Consolidated Statement of Income and Comprehensive Income.
Recent Accounting Pronouncements	Recen t Accounting Pronouncements Recently Adopted Accounting Guidance In October 2021, the FASB issued ASU 2021-08, “Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers,” which requires entities to apply Topic 606 to recognize and measure contract assets and contract liabilities in a business combination as if it had originated the contracts. The standard is effective for public companies for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022. Early adoption is permitted. We adopted the new standard effective January 1, 2023 and the guidance did not have a material impact on our consolidated financial statements.

[1] The Company's time deposits consist of domestic deposits which mature within nine months (Level 2). Level 2 investments are priced using observable inputs, such as quoted prices in markets that are not active and yield curves. Contingent consideration liabilities are measured using the income approach and discounted to present value based on an assessment of the probability that the Company would be required to make such future payments. The contingent consideration liabilities are measured at fair value using significant Level 3 (unobservable) inputs, such as discount rates and probability measures. Remeasurement of the contingent consideration to fair value is expensed through the income statement in the period remeasured. Contingent consideration–current is included in accrued expenses and other current liabilities on the balance sheet.

Additionally, in calculating diluted net income per share, we excluded the impact of interest expense and amortization of note costs relating to the shares issuable upon conversion of our outstanding convertible notes from net income and included the weighted average of 3.9 million common shares under the if-converted method for each of the three and six months ended June 30, 2023 and for each of the three and six months ended June 30, 2022, respectively. The interest expense including amortization of note issuance costs, related to convertible notes was $ 0.6 million for each of the three months ended June 30, 2023 and June 30 2022, and $ 1.3 million for the six months ended June 30, 2022 . For the six months ended June 30, 2023, the interest expense and amortization of note costs relating to the shares issuable upon conversion of our outstanding convertible notes were excluded from the calculation as they would have been anti-dilutive.
