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, 2021, 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 does business for the 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, 2021 . 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. 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. 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 March 31, 2022 , the Company’s collectability assessment continues to include the business and market disruptions caused by COVID-19 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 debt investments 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. Recent Accounting Pronouncements Accounting Guidance Not Yet Adopted In October 2021, the FASB issued ASU 2021-08 "Accounting for Contract Assets and Contract Liabilities from Contracts with Customers," which clarified the accounting for acquired revenue contracts with customers in a business combination. ASU 2021-08 requires acquirers to measure contract assets and contract liabilities acquired in a business combination in accordance with ASC 606. As a result, it is generally expected that an acquirer will recognize and measure contract assets and liabilities in a manner consistent with how they were recognized by the acquiree in its preacquisition financial statements. The guidance is effective for interim and annual periods beginning after December 15, 2022, with early adoption permitted. Early adoption in an interim period requires that the amendments be applied retrospectively to all business combinations for which the acquisition occurs on or after the beginning of the fiscal year including the interim period and prospectively to all business combinations that occur on or after the date of initial application. We are currently evaluating the impact of the new guidance on our consolidated financial statements.

Revenue Recognition [Abstract]
Revenue	3. Revenue Disaggregation of Revenue The following table depicts the disaggregation of revenue according to categories consistent with how the Company evaluates its financial performance and economic risk. International revenue consists of international geo-targeted campaigns, which are campaigns targeted at an audience of members outside of North America. For the Three Months Ended 2022 2021 North America $ 43,587 $ 33,038 International 24,578 19,931 Total $ 68,165 $ 52,969 Contract Liabilities Timing may differ between the satisfaction of performance obligations and the invoicing and collections of amounts related to the Company’s contracts with customers. 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 $ 2.5 million and $ 2.6 million at March 31, 2022, and December 31, 2021, respectively. Contract Liabilities Year-to-Date Activity Balance at December 31, 2021 $ 30,492 Billings 75,380 Revenue Recognized ( 68,165 ) Balance at March 31, 2022 $ 37,707 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 March 31, 2022 Quoted Prices Significant Significant Assets: Short-term investments (1) $ 20,020 $ — $ 20,020 $ — Total assets $ 20,020 $ — $ 20,020 $ — Liabilities: Contingent consideration - current (2) $ 3,209 $ — $ — $ 3,209 Total liabilities $ 3,209 $ — $ — $ 3,209 Fair Value Measurements at December 31, 2021 Quoted Prices Significant Significant Assets: Short-term investments (1) $ 20,076 $ 15,000 $ 5,076 $ — Total assets $ 20,076 $ 15,000 $ 5,076 $ — Liabilities: Contingent consideration - current (2) $ 5,200 $ — $ — $ 5,200 Contingent consideration - non-current (2) 2,779 — — 2,779 Total liabilities $ 7,979 $ — $ — $ 7,979 (1) Short-term investments consist of money market funds (Level 1) and pooled bond funds (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 and contingent considerations–non-current is included in other liabilities on the balance sheet.

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 March 31, 2022 , 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 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 convert ible dates, 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 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 the applicable 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. The conversion features of the 2025 Notes was triggered as of December 31, 2021 as the last reported trading price of our common stock was greater than or equal to 130 % of the conversion prices for at least 20 trading days in the period of 30 consecutive trading days ending on, and including, the last trading day of the quarter ended December 31, 2021 and therefore the 2025 Notes were convertible, in whole or in part, at the option of the holders from January 1, 2022 through March 31, 2022. After March 31, 2022, the 2025 Notes were no longer convertible at the option of the holder. The 2026 Notes have not become convertible. Whether the 2026 Notes or 2025 Notes will be convertible prior to September 14, 2025 in the case of the 2025 Notes or September 14, 2026 for the 2026 Notes will depend on the satisfaction of the trading price condition or another conversion condition specified in the Indentures in the future.

The 2021 Loan Agreement provides for a $ 75 million revolving credit facility with a $ 5 million letter-of-credit sublimit and matures on October 29, 2023 . The 2021 Loan Agreement is secured by substantially all of the Company’s assets. Borrowings under the 2021 Loan Agreement bear interest at a rate equal to one (1) month U.S. LIBOR, plus a spread based upon the Company’s leverage (as defined by 2021 Loan Agreement), which may vary between 2.00 % and 2.75 %. As of March 31, 2022, the interest rate was 2.98 % . The 2021 Loan Agreement is subject to various leverage and non-financial covenants.

Lessee Disclosure [Abstract]
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, 2021. 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 2022 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 March 31, 2022, operating lease assets were $ 22.4 million and operating lease liabilities were $ 27.1 million. The maturities of the Company’s operating lease liabilities as of March 31, 2022 were as follows: Minimum Lease Years Ending December 31: Payments 2022 (April 1 – December 31) $ 3,373 2023 4,650 2024 4,591 2025 3,801 2026 3,793 Thereafter 9,930 Total future minimum lease payments 30,138 Less imputed interest 3,042 Total operating lease liabilities $ 27,096 Included in the Consolidated Balance Sheet: Current operating lease liability $ 4,157 Non-current operating lease liability 22,939 Total operating lease liabilities $ 27,096 For the three months ended March 31, 2022 and 2021, the total lease cost was comprised of the following amounts: Three Months Ended 2022 2021 Operating lease expense $ 1,141 $ 1,142 Short-term lease expense 9 76 Total lease expense $ 1,150 $ 1,218 The following summarizes additional information related to operating leases: As of March 31, 2022 Weighted-average remaining lease term — operating leases 4.1 Weighted-average discount rate — operating leases 3 % 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 March 31, 2022 and December 31, 2021 , the Company did no t have any pending 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.

Disclosure Of Compensation Related Costs Sharebased Payments [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 37,500 shares of common stock that remain subject to outstanding stock grants under the 2007 Plan as of March 31, 2022. 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 1,657,449 shares of common stock that remain subject to outstanding stock-based grants under the 2017 Plan as of March 31, 2022 . A total of 3,056,185 shares of common stock remain available for issuance under the 2017 Plan as of March 31, 2022. 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 three months ended March 31, 2022 is presented below: Three Month Activity Options Weighted- Weighted- Aggregate Options outstanding at December 31, 2021 125,000 $ 25.49 — — Granted 2,500 88.32 — — Exercised — — — — Forfeited — — — — Cancelled — — — — Options outstanding at March 31, 2022 127,500 $ 26.72 6.17 $ 6,974 Options exercisable at March 31, 2022 105,000 $ 17.60 5.51 $ 6,687 Options vested or expected to vest at March 31, 2022 127,005 $ 26.54 6.16 $ 6,969 There were no options exercised during the three months ended March 31, 2022 and March 31, 2021.

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 $ 2.9 million for the three months ended March 31, 2022. The tax expense for the three months ended March 31, 2022 increased by approximately $ 2.2 million, as compared to the same period in 2021, primarily due to $ 7.6 million increase in pretax income offset by an approximate $ 0.1 million increase in excess tax benefits of stock-based compensation.

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 does business for the BrightTALK webinar and virtual event platform.
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, 2021 .
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. 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.
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 March 31, 2022 , the Company’s collectability assessment continues to include the business and market disruptions caused by COVID-19 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 debt investments 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	Recent Accounting Pronouncements Accounting Guidance Not Yet Adopted In October 2021, the FASB issued ASU 2021-08 "Accounting for Contract Assets and Contract Liabilities from Contracts with Customers," which clarified the accounting for acquired revenue contracts with customers in a business combination. ASU 2021-08 requires acquirers to measure contract assets and contract liabilities acquired in a business combination in accordance with ASC 606. As a result, it is generally expected that an acquirer will recognize and measure contract assets and liabilities in a manner consistent with how they were recognized by the acquiree in its preacquisition financial statements. The guidance is effective for interim and annual periods beginning after December 15, 2022, with early adoption permitted. Early adoption in an interim period requires that the amendments be applied retrospectively to all business combinations for which the acquisition occurs on or after the beginning of the fiscal year including the interim period and prospectively to all business combinations that occur on or after the date of initial application. We are currently evaluating the impact of the new guidance on our consolidated financial statements.

(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 and contingent considerations–non-current is included in other liabilities on the balance sheet.
