Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies The accompanying consolidated financial statements reflect the application of certain significant accounting policies as described below and elsewhere in these Notes to Consolidated Financial Statements. The Company’s critical accounting policies are those that affect its more significant judgments used in the preparation of its 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, 2017, and in this note to the consolidated financial statements. There were no material changes to the Company’s critical accounting policies and use of estimates during the first three months of 2018, other than those related revenue recognition resulting from the adoption of a new accounting pronouncement, as described in this Note 2 under “Revenue Recognition”. Principles of Consolidation The accompanying 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 (Beijing) Information Technology Consulting Co. Ltd. (“TTGT Consulting”), TechTarget (Australia) Pty Ltd., TechTarget (Singapore) Pte Ltd., E-Magine Médias SAS (“LeMagIT”) and TechTarget Germany GmbH. 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. Additionally, through its wholly-owned subsidiaries, TTGT HK and TTGT Consulting, the Company effectively controls a variable interest entity (“VIE”), Keji Wangtuo Information Technology Co., Ltd., (“KWIT”), which was incorporated under the laws of the People’s Republic of China (“PRC”). In 2018, TechTarget began modifying its PRC operations and consolidating its activities with other TechTarget locations. 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. PRC laws and regulations prohibit or restrict foreign ownership of internet-related services and advertising businesses. To comply with these foreign ownership restrictions, the Company operates its websites and provides online advertising services in the PRC through KWIT. The Company entered into certain exclusive agreements with KWIT and its shareholders through TTGT HK, which obligated TTGT HK to absorb all of the risk of loss from KWIT’s activities and entitled TTGT HK to receive all of its residual returns. In addition, the Company entered into certain agreements with the authorized parties through TTGT HK, including Management and Consulting Services, Voting Proxy, Equity Pledge and Option Agreements. TTGT HK assigned all of its rights and obligations to the newly formed wholly foreign-owned enterprise, TTGT Consulting. TTGT Consulting is established and existing under the laws of the PRC, and is wholly owned by TTGT HK. Based on these contractual arrangements, the Company consolidates the financial results of KWIT as required by Accounting Standards Codification (“ASC”) subtopic 810-10, Consolidation: Overall, because the Company holds all the variable interests of KWIT through TTGT Consulting, which is the primary beneficiary of KWIT. Despite the lack of technical majority ownership, there exists a parent-subsidiary relationship between the Company and the VIE through the aforementioned agreements, whereby the equity holders of KWIT assigned all of their voting rights underlying their equity interest in KWIT to TTGT Consulting. In addition, through the other aforementioned agreements, the Company demonstrates its ability and intention to continue to exercise the ability to obtain substantially all of the profits and absorb all of the expected losses of KWIT. All significant intercompany accounts and transactions among the Company, its subsidiaries, and KWIT have been eliminated in consolidation. Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted (Generally Accepted Accounting Principles or “ ” “U.S.” Use of Estimates The preparation of consolidated financial statements in conformity with 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 consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, the Company evaluates its estimates, including those related to revenues, long-lived assets, goodwill, the allowance for doubtful accounts, stock-based compensation, earnouts, self-insurance accruals, 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 substantially all of its revenues from the sale of targeted marketing and advertising campaigns, which it delivers via its network of websites, data analytics solutions, and, historically, events. 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) i dentifying 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 Recent Accounting Pronouncements Recently Adopted Accounting Guidance In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“Topic 606”), which supersedes the revenue recognition requirements in ASC 605, Revenue Recognition (“Topic 605”). Topic 606 is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Topic 606 provides that an entity should apply a five-step approach for recognizing revenue, as described above in this Note 2 under “Revenue Recognition.” This guidance also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. The Company adopted the standard effective January 1, 2018, using the modified retrospective approach. Under this method, the Company evaluated contracts that were in effect at the beginning of fiscal 2018 as if those contracts had been accounted for under Topic 606. Under the modified retrospective approach, periods prior to the adoption date were not adjusted and continue to be reported in accordance with historical, pre-Topic 606 accounting. The adoption of the standard did not have a material effect on the Company’s consolidated financial statements, systems, processes, or internal controls. Accounting Guidance Not Yet Adopted In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”). ASU 2016-02 establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the Consolidated Statements of Operations and Comprehensive Income. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company is currently evaluating the impact that this guidance will have on its consolidated financial statements and disclosures. However, the Company anticipates that this standard will have a material impact on its financial position, primarily due to office space operating leases, for which the Company will be required to recognize lease assets and lease liabilities on its Consolidated Balance Sheets. The Company will continue to assess the potential impacts of this standard, including the impact the adoption of this guidance will have on its results of operations or cash flows, if any. In January 2017, the FASB issued ASU No. 2017-04, Intangibles-Goodwill and Other (Topic 350), Simplifying the Test for Goodwill Impairment ("ASU 2017-04"). ASU 2017-04 eliminates the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge (step 2 of the goodwill impairment test) and instead requires only a one-step quantitative impairment test, performed by comparing the fair value of goodwill with its carrying amount. ASU 2017-04 is effective on a prospective basis effective for goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for goodwill impairment tests performed on testing dates after January 1, 2017. The Company is currently evaluating the impact that this guidance will have on its consolidated financial statements and disclosures.

Revenue Recognition [Abstract]
Revenues	3. Revenues Revenue Recognition On January 1, 2018, the Company adopted Topic 606 and, as such, recognizes revenue when performance obligations are satisfied by transferring promised goods or services to customers in an amount the Company expects to receive in exchange for those goods or services. The Company enters into contracts that can include various combinations of its offerings, which are generally capable of being distinct and accounted for as separate performance obligations. The Company’s offerings consist of IT Deal Alert and Core Online categories. IT Deal Alert provides a suite of products that leverages detailed purchase intent data that we collect about end-user IT organizations. Through proprietary scoring methodologies, we use this insight to help our customers identify and prioritize accounts. We provide this insight through Priority Engine TM TM TM TM TM Core Online consists primarily of demand solutions, brand solutions, and custom content. Demand solutions offerings provide the Company’s customers the opportunity to maximize return on investment by capturing sales leads from the distribution and promotion of content to its audience. Demand solutions may contain the following components: White Papers, Webcasts, Podcasts, Videocasts and Virtual Trade Shows, and Content Sponsorship, which the Company may utilize at its discretion. Brand Solutions provide the Company’s customers to target audiences of IT and business professionals actively researching information related to their products and services. This can be accomplished through on-network or off-network branding as well as through the hosting of Microsites. The Company will at times create white papers, case studies, webcasts, or videos to our customers’ specifications through its Custom Content team (“custom content”). Revenue from demand solutions is primarily recognized when the transfer of control occurs. For certain demand solutions, the Company generates revenue on a cost per lead basis and the transfer of control occurs at the point in time each lead is generated. Certain of the contracts within demand solutions are duration-based campaigns which, in the event of customer cancellation, provide the Company with an enforceable right to a proportional payment for the portion of the campaign based on services provided. Accordingly, revenue from duration-based campaigns are recognized using a time-based measure of progress, which the Company believes best depicts how it satisfies its performance obligations in these arrangements as control is continuously transferred throughout the contract period. Revenue from brand solutions is primarily recognized when the placement of the branding impression appears. Revenue from Microsites is recognized ratably over the life of the contract. The Company’s offerings can be sold separately but the Company’s contracts often involve multiple offerings. The Company evaluates all contracts with customers at inception to determine whether they contain separate performance obligations. If the contract contains a single performance obligation, the entire transaction price is allocated to that performance obligation. If the contract contains multiple performance obligations, the transaction price is allocated to each performance obligation based on a relative standalone selling price. The Company has concluded that each of the performance obligations described above are distinct. To determine standalone selling price for the individual performance obligations in the arrangement, the Company uses an estimate of the observable selling prices in separate transactions. The Company establishes best estimates considering multiple factors including, but not limited to, class of client, size of transaction, available inventory, pricing strategies and market conditions. The Company uses a range of amounts to estimate stand-alone selling price when it sells the goods and services separately and needs to determine whether a discount is to be allocated based upon the relative stand-alone selling price to the various goods and services. Disaggregation of Revenue The following table depicts the disaggregation of revenue according to categories consistent with how the Company evaluates its financial performance: Three Months Ended March 31, Percent 2018 2017 Change ($ in thousands) Total Online $ 27,299 $ 23,409 17 % Total Online by Geographic Area: North America: North America IT Deal Alert 10,006 8,168 23 % North America Core Online 8,844 8,078 9 % Total North America Online 18,850 16,246 16 % International: International IT Deal Alert 3,607 2,203 64 % International Core Online 4,842 4,960 (2 )% Total International Online 8,449 7,163 18 % Total Online by Product: IT Deal Alert: North America IT Deal Alert 10,006 8,168 23 % International IT Deal Alert 3,607 2,203 64 % Total IT Deal Alert 13,613 10,371 31 % Core Online: North America Core Online 8,844 8,078 9 % International Core Online 4,842 4,960 (2 )% Total Core Online 13,686 13,038 5 % Total Events $ — $ 168 (100 )% Total Revenues $ 27,299 $ 23,577 16 % Deferred Revenue and Contract Balances Timing may differ between the satisfaction of performance obligations and the invoicing and collection 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. Deferred revenue is included in contract liabilities on the accompanying Consolidated Balance Sheets and was $1.8 million and $4.9 million at March 31, 2018 and December 31, 2017, respectively. The Company’s adoption of ASC 606 reduced the Company’s deferred revenue by $3.4 million as of March 31, 2018. 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 customers 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 amounts included in contract liabilities on the accompanying Consolidated Balance Sheets were $2.8 million and $2.7 million at March 31, 2018 and December 31, 2017, respectively. During the first quarter of 2018, revenues of $4.7 million were recognized that had been included in the contract liabilities balance at December 31, 2017. Contract Liabilities Year-to-Date Activity (in thousands) Balance at December 31, 2017 $ 4,088 Deferral of revenue 1,643 Recognition of previously unearned revenue (1,146 ) Balance at March 31, 2018 $ 4,585 The Company reduced its accounts receivable by $3.5 million from $29.6 million to $26.1 million as of January 1, 2018 as a result of the adoption of Topic 606. There was a corresponding reduction of $3.5 million to its deferred revenue balance from $7.6 million to $4.1 million as of January 1, 2018 as a result of the adoption of Topic 606. Payment terms and conditions vary by contract type, although terms generally include requirement of payment within 30 to 90 days. In instances where the timing of revenue recognition differs from the timing of invoicing, the Company has determined its contracts do not contain a financing component as they are generally less than one year. The Company increased its allowance for doubtful accounts by $0.2 million and had direct write-offs of $17, net of recoveries, during the three months ended March 31, 2018. The Company elected to apply the following practical expedients and exemptions: • The Company does not disclose the value of unsatisfied performance obligations for contracts with an original expected duration of one year or less. • The Company expenses, as incurred, contract costs consisting of sales commissions and sales bonuses because the amortization period of the contract asset that would have otherwise been recognized would have been one year or less.

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 cash equivalents, short-term and long-term investments and contingent consideration. 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 and liabilities carried at fair value and measured on a recurring basis is as follows: Fair Value Measurements at Reporting Date Using March 31, 2018 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Assets: Money market funds (1) $ 9,721 $ 9,721 $ — $ — Short-term investments(2) 5,617 — 5,617 — Total assets $ 15,338 $ 9,721 $ 5,617 $ — Fair Value Measurements at Reporting Date Using December 31, 2017 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Assets: Money market funds(1) $ 7,155 $ 7,155 $ — $ — Short-term investments(2) 7,650 — 7,650 — Long-term investments(2) 496 — 496 — Total assets $ 15,301 $ 7,155 $ 8,146 $ — (1) Included in cash and cash equivalents on the accompanying Consolidated Balance Sheets; valued at quoted market prices in active markets.

Cash, Cash Equivalents, and Investments	5. Cash, Cash Equivalents, and Investments Cash and cash equivalents consist of highly liquid investments with maturities of three months or less at date of purchase. Cash equivalents are carried at cost, which approximates their fair market value. Cash and cash equivalents consisted of the following: March 31, 2018 December 31, 2017 Cash $ 15,701 $ 18,811 Money market funds 9,721 7,155 Total cash and cash equivalents $ 25,422 $ 25,966 The Company’s short-term and long-term investments are accounted for as available for sale securities. These investments are recorded at fair value with the related unrealized gains and losses included in accumulated other comprehensive gain, a component of stockholders’ equity, net of tax.

Stock-Based Compensation	10. Stock-Based Compensation Stock Option and Incentive Plans In April 2007, the Board 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 ISOs, 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. At the inception of the plan, t he Company reserved for issuance an aggregate of 2,911,667 shares of common stock under the 2007 Plan, which expired in May 2017. The 2007 Plan was subject to an automatic annual increase of shares on January 1 of each year, beginning on January 1, 2008, equal to the lesser of (a) 2% of the outstanding number of shares of common stock (on a fully-diluted basis) on the immediately preceding December 31 and (b) such lower number of shares as may be determined by the compensation committee of the Board. The number of shares available for issuance under the 2007 Plan was subject to adjustment in the event of a stock split, stock dividend or other change in capitalization. Approximately 8,224,334 shares were added to the 2007 Plan in accordance with the automatic annual increase and other provisions. 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. In March 2017, the Board 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 that date, approximately 3,000,000 shares of 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. 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. 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 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”), they would be subject to the same vesting and forfeiture provisions as the underlying award. There is a total of 680,000 shares of common stock that remain subject to outstanding stock grants under the 2017 Plan as of March 31, 2018. 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 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, 2018 is presented below: Year-to-Date Activity Options Outstanding Weighted- Average Exercise Price Per Share Weighted- Average Remaining Contractual Term in Years Aggregate Intrinsic Value Options outstanding at December 31, 2017 344,090 $ 6.41 Granted — — Exercised (74,375 ) 5.46 $ 825 Forfeited — — Cancelled — — Options outstanding at March 31, 2018 269,715 $ 6.67 3.31 $ 3,564 Options exercisable at March 31, 2018 249,715 $ 6.37 2.82 $ 3,373 Options vested or expected to vest at March 31, 2018 267,755 $ 6.65 3.26 $ 3,545 During the three months ended March 31, 2018, the total intrinsic value of options exercised (i.e. the difference between the market price at exercise and the price paid by the employee to exercise the options) was $0.8 million. During the three months ended March 31, 2017, the total intrinsic value of options exercised was not material. The total amount of cash received from exercise of these options was approximately $0.4 million and $0.1 million during the three months ended March 31, 2018 and 2017, respectively. 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 three months ended March 31, 2018 is presented below: Year-to-Date Activity Shares Weighted- Average Grant Date Fair Value Per Share Aggregate Intrinsic Value Nonvested outstanding at December 31, 2017 1,414,000 $ 9.37 Granted — — Vested — — Forfeited — — Nonvested outstanding at March 31, 2018 1,414,000 $ 9.37 $ 28,110 There were no restricted stock units that vested during the three months ended March 31, 2018 or 2017.

Common Stock Repurchase Program In June 2016, the Company announced that the Board had authorized a $20.0 million stock repurchase program (the “Repurchase Program”), whereby the Company was authorized to repurchase the Company’s common stock from time to time on the open market or in privately negotiated transactions at prices and in the manner determined by the Board. On May 5, 2017, the Company’s Board reauthorized the common stock repurchase program to allow the Company to use the remaining balance of the unused authorization under the Repurchase Program after its original expiration in June 2017. The reauthorized program allows the Company to repurchase its common stock from time to time on the open market or in privately negotiated transactions at prices and in the manner that may be determined by management. The reauthorized program has no time limit and may be suspended at any time. Additionally, the Company may establish, from time to time, 10b5-1 trading plans that will provide flexibility as it buys back its shares. Pursuant to the Repurchase Program, the Company repurchased 112,303 and 161,147 shares of common stock for an aggregate purchase price of $1.6 million and $1.4 million in the three months ended March 31, 2018 and 2017, respectively.

The Company recognized income tax benefits for discrete items of $0.4 million and $0.1 million during the three months ended March 31, 2018 and 2017, respectively. 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.

Changes include, but are not limited to, a corporate tax rate decrease from 35% to 21% effective for tax years beginning after December 31, 2017 and a one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings as of December 31, 2017. On December 22, 2017, Staff Accounting Bulletin No. 118 was issued to address the application of US GAAP in situations when a registrant does not have the necessary information available, prepared or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Act. For the three months ended March 31, 2018, the Company obtained additional information affecting the provisional amount initially recorded for the transition tax for the three months ended December 31, 2017. As a result, the Company recorded an immaterial adjustment to the transition tax. Additional investigation is necessary to do a more detailed analysis of historical foreign earnings as well as potential correlative adjustments. Any subsequent adjustment to the amount will be recorded to current tax expense in the quarter of 2018 when the analysis is complete. In the first quarter of 2017, the Company adopted ASU 2016-09, which requires that all excess tax benefits and tax deficiencies related to stock compensation be recognized as income tax expense or benefit in the Consolidated Statement of Operations and Comprehensive Income in the period incurred. 0 As part of adopting ASU 2016-09, the Company recorded deferred tax assets for the federal and state excess tax benefit net operating losses in the amount of $0.2 million, with an offsetting entry to retained earnings.

Ltd. (“TTGT Consulting”), TechTarget (Australia) Pty Ltd., TechTarget (Singapore) Pte Ltd., E-Magine Médias SAS (“LeMagIT”) and TechTarget Germany GmbH. 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. Additionally, through its wholly-owned subsidiaries, TTGT HK and TTGT Consulting, the Company effectively controls a variable interest entity (“VIE”), Keji Wangtuo Information Technology Co., Ltd., (“KWIT”), which was incorporated under the laws of the People’s Republic of China (“PRC”). In 2018, TechTarget began modifying its PRC operations and consolidating its activities with other TechTarget locations. 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. PRC laws and regulations prohibit or restrict foreign ownership of internet-related services and advertising businesses. To comply with these foreign ownership restrictions, the Company operates its websites and provides online advertising services in the PRC through KWIT. The Company entered into certain exclusive agreements with KWIT and its shareholders through TTGT HK, which obligated TTGT HK to absorb all of the risk of loss from KWIT’s activities and entitled TTGT HK to receive all of its residual returns. In addition, the Company entered into certain agreements with the authorized parties through TTGT HK, including Management and Consulting Services, Voting Proxy, Equity Pledge and Option Agreements. TTGT HK assigned all of its rights and obligations to the newly formed wholly foreign-owned enterprise, TTGT Consulting. TTGT Consulting is established and existing under the laws of the PRC, and is wholly owned by TTGT HK. Based on these contractual arrangements, the Company consolidates the financial results of KWIT as required by Accounting Standards Codification (“ASC”) subtopic 810-10, Consolidation: Overall, because the Company holds all the variable interests of KWIT through TTGT Consulting, which is the primary beneficiary of KWIT. Despite the lack of technical majority ownership, there exists a parent-subsidiary relationship between the Company and the VIE through the aforementioned agreements, whereby the equity holders of KWIT assigned all of their voting rights underlying their equity interest in KWIT to TTGT Consulting. In addition, through the other aforementioned agreements, the Company demonstrates its ability and intention to continue to exercise the ability to obtain substantially all of the profits and absorb all of the expected losses of KWIT. All significant intercompany accounts and transactions among the Company, its subsidiaries, and KWIT have been eliminated in consolidation.
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted (Generally Accepted Accounting Principles or “ ” “U.S.”
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with 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 consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, the Company evaluates its estimates, including those related to revenues, long-lived assets, goodwill, the allowance for doubtful accounts, stock-based compensation, earnouts, self-insurance accruals, 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 substantially all of its revenues from the sale of targeted marketing and advertising campaigns, which it delivers via its network of websites, data analytics solutions, and, historically, events. 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) i dentifying 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
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recently Adopted Accounting Guidance In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“Topic 606”), which supersedes the revenue recognition requirements in ASC 605, Revenue Recognition (“Topic 605”). Topic 606 is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Topic 606 provides that an entity should apply a five-step approach for recognizing revenue, as described above in this Note 2 under “Revenue Recognition.” This guidance also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. The Company adopted the standard effective January 1, 2018, using the modified retrospective approach. Under this method, the Company evaluated contracts that were in effect at the beginning of fiscal 2018 as if those contracts had been accounted for under Topic 606. Under the modified retrospective approach, periods prior to the adoption date were not adjusted and continue to be reported in accordance with historical, pre-Topic 606 accounting. The adoption of the standard did not have a material effect on the Company’s consolidated financial statements, systems, processes, or internal controls. Accounting Guidance Not Yet Adopted In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”). ASU 2016-02 establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the Consolidated Statements of Operations and Comprehensive Income. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company is currently evaluating the impact that this guidance will have on its consolidated financial statements and disclosures. However, the Company anticipates that this standard will have a material impact on its financial position, primarily due to office space operating leases, for which the Company will be required to recognize lease assets and lease liabilities on its Consolidated Balance Sheets. The Company will continue to assess the potential impacts of this standard, including the impact the adoption of this guidance will have on its results of operations or cash flows, if any. In January 2017, the FASB issued ASU No. 2017-04, Intangibles-Goodwill and Other (Topic 350), Simplifying the Test for Goodwill Impairment ("ASU 2017-04"). ASU 2017-04 eliminates the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge (step 2 of the goodwill impairment test) and instead requires only a one-step quantitative impairment test, performed by comparing the fair value of goodwill with its carrying amount. ASU 2017-04 is effective on a prospective basis effective for goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for goodwill impairment tests performed on testing dates after January 1, 2017. The Company is currently evaluating the impact that this guidance will have on its consolidated financial statements and disclosures.
