Organization, Consolidation and Presentation of Financial Statements [Abstract]
The Company and Summary of Significant Accounting Policies	The Company and Summary of Significant Accounting Policies Description of Company Web.com Group, Inc. ("Web.com" or "the Company") provides a full range of Internet services to small businesses to help them compete and succeed online. Web.com meets the needs of small businesses anywhere along their lifecycle with affordable, subscription-based solutions including domains, hosting, website design and management, search engine optimization, online marketing campaigns, local sales leads, social media, mobile products and eCommerce solutions. The Company has reviewed the criteria of Accounting Standards Codification (“ASC”) 280-10, Segment Reporting, and has determined that the Company is comprised of only one segment, web services and products. Use of Estimates The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Foreign Currency Translation The functional currency of the Company’s United Kingdom-based operations acquired in July 2014 is the British Pound. The Company translates the financial statements of this subsidiary to U.S. dollars using month-end rates of exchange for assets and liabilities, historical rates of exchange for equity and average rates of exchange for revenues, costs, and expenses. Translation gains and losses are recorded in accumulated other comprehensive (loss) income as a component of stockholders’ equity. In addition, the Company’s foreign operations include a customer service center and an outbound sales center in Canada and a technology center in Argentina. The Company records foreign currency transaction gains and losses, realized and unrealized and measurement of local currencies of these foreign subsidiaries where the foreign currency is different from the local currency in the consolidated statements of income (loss). During the years ended December 31, 2015, 2014 and 2013, the Company recorded approximately $0.4 million , $0.3 million and $0.2 million , respectively. Principles of Consolidation The Company’s consolidated financial statements include the assets, liabilities and the operating results of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated. Revenue Recognition and Deferred Revenue The Company recognizes revenue in accordance with ASC 605, Revenue Recognition . The Company recognizes revenue when all of the following conditions are satisfied: (1) there is persuasive evidence of an arrangement; (2) the service has been provided to the customer; (3) the amount of fees to be paid by the customer is fixed or determinable; and (4) the collection of our fees is reasonably assured. Thus, the Company recognizes subscription revenue on a daily basis, as services are provided. Customers are billed for the subscription on a monthly, quarterly, semi-annual, annual or on a multi-year basis, at the customer’s option. For all of the Company’s customers, regardless of the method the Company uses to bill them, subscription revenue is recorded as deferred revenue in the accompanying consolidated balance sheets. As services are performed, the Company recognizes subscription revenue on a daily basis over the applicable service period. When the Company provides a free trial period, the Company does not begin to recognize subscription revenue until the trial period has ended and the customer has been billed for the services. The Company accounts for our multi-element arrangements in accordance with ASC 605-25, Revenue Recognition: Multiple-Element Arrangement. The Company may sell multiple products or services to customers at the same time. For example, we may design a customer website and separately offer other services such as hosting and marketing or a customer may combine a domain registration with other services such as private registration or e-mail. In accordance with ASC 605-25, each element is accounted for as a separate unit of accounting provided the following criteria is met: the delivered products or services has value to the customer on a standalone basis; and for an arrangement that includes a general right of return relative to the delivered products or services, delivery or performance of the undelivered product or service is considered probable and is substantially controlled by the Company. The Company considers a deliverable to have standalone value if the product or service is sold separately by us or another vendor or could be resold by the customer. Our products and services do not include a general right of return relative to the delivered products. In cases where the delivered products or services do not meet the separate unit of accounting criteria, the deliverables are combined and treated as one single unit of accounting for revenue recognition. The Company assigns value to the separate units of accounting in multiple-element arrangements using the relative selling price method which is calculated by taking the standalone selling price of each unit to the total selling price of the arrangement, multiplied by the total sales price. Typically, the deliverables within multiple-element arrangements are provided over the same service period, and therefore revenue is recognized over the same period. To determine the selling price in multiple-element arrangements, the Company establishes vendor-specific objective evidence of the selling price using the price of the deliverable when sold separately. If we are unable to determine the selling price because vendor-specific objective evidence does not exist, the Company will first look to third party evidence, and if that is not sufficient, it will determine an estimated sales price through consultation with and approval by the Company’s management, taking into consideration the Company’s relative costs, target profit margins, and any other information gathered during this process. The Company incurs direct costs, primarily related to outbound and inbound sales call centers, to acquire new customers. Frequently, these new customers purchase products that result in the deferral of revenue by the Company. All direct costs related to acquiring new customers are expensed in the period incurred and not deferred over the related deferred revenue contract term. Cash and Cash Equivalents Cash and cash equivalents include cash on hand and bank demand deposit accounts. For purposes of presentation in the Consolidated Balance Sheets, the Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents. Concentrations of Credit Risk Financial instruments that potentially subject the Company to concentration of credit risk consist principally of cash and cash equivalents and trade receivables. The Company invests its cash in cash and credit instruments of highly rated financial institutions; three institutions hold 95% of the Company's total cash and cash equivalents. Concentrations of credit risk with respect to trade accounts receivable are limited due to the large number of customers comprising the Company’s customer base and their geographic dispersion. The Company has not incurred any significant credit related losses. Accounts Receivable Accounts receivable are recorded on the balance sheet at net realizable value. The Company’s management uses historical collection percentages and customer-specific information, when available, to estimate the amount of trade receivables that are uncollectible and establishes reserves for uncollectible balances based on this information. Generally receivables are classified as past due after 60 days . Trade receivables are written off once collection efforts are exhausted. The Company does not generally require deposits or other collateral from customers. Bad debt expense reported in operating expenses excludes provisions made to the allowance for doubtful accounts for anticipated refunds and automated clearinghouse returns that are recorded as an adjustment to revenue. Included in the accounts receivable line item in the Consolidated Balance Sheets as of the year ended December 31, 2015 and 2014 is approximately $1.1 million and $2.4 million , respectively, of miscellaneous receivables primarily due from the Canadian government for job creation incentive rebates and for sales and use tax. Deferred Expenses Deferred expenses primarily consist of prepaid domain name registry fees that are paid in full at the time a domain name is registered. The registry fees are recognized on a straight-line basis over the term of the domain registration period. Goodwill and Other Intangible Assets The Company continued to perform the quantitative tests to determine if it is more likely than not that the carrying value of our goodwill and indefinite-lived intangible assets are impaired for our annual test at December 31, 2015 . The Company tests goodwill and intangible assets for impairment using one reporting unit. A market approach is used to test goodwill for impairment, while our intangible asset test uses the income approach. The following is not a complete discussion of the Company’s calculations, but outlines the general assumptions and steps for testing goodwill and intangible assets for impairment: Goodwill The first step involves comparing the fair value of our reporting unit to its carrying value, including goodwill. The Company uses a market capitalization approach after considering an estimated control premium. If the carrying value exceeds its fair value, the second step of the test is performed by comparing the carrying value of goodwill to its implied fair value. An impairment charge is recognized for the excess of the carrying value over its implied fair value. Intangible Assets The Company estimates the fair value of indefinite-lived intangibles using the relief-from-royalty method, a form of the income approach. It is based on the principle that ownership of the intangible asset relieves the owner of the need to pay a royalty to another party in exchange for rights to use the asset. Key assumptions in estimating the fair value include, among other items, forecasted revenue, royalty rates, tax rate, and the benefit of tax amortization. The Company employs a weighted-average cost of capital approach to determine the discount rates used in our projections. The determination of the discount rate includes certain factors such as, but not limited to, the risk-free rate of return, market risk, size premium, and the overall level of inherent risk. If the carrying value of the intangibles exceeds its fair value, an impairment charge is recognized. The results of these analyses indicated that the Company’s goodwill and indefinite-lived intangible assets were not impaired at December 31, 2015 . Technology and Development Costs The Company expenses technology and development costs as incurred. Property and Equipment Property and equipment, including software, are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are provided over the estimated useful lives of the assets using the straight-line method. Depreciation expense includes the amortization of assets recorded under capital leases. The asset lives used are presented in the table below: Average Life in Years Computer equipment 3 - 5 Software 2 - 3 Furniture and fixtures 5 Other equipment 5 - 6 Buildings 30 Building improvements 15 Leasehold improvements Shorter of asset’s life Advertising Advertising costs are expensed as incurred. Included in advertising are general marketing, corporate sponsorships as well as online marketing and banner advertisements. Total advertising expense was $50.1 million , $55.9 million and $64.7 million for the years ending December 31, 2015 , 2014 and 2013 , respectively. Income Taxes The Company accounts for income taxes under the provisions of ASC 740, Income Taxes , using the liability method. ASC 740 requires recognition of deferred tax liabilities and assets for the expected future tax consequences of events that have been included in the financial statements or tax returns. Under this method, deferred tax liabilities and assets are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the difference is expected to reverse. Further, deferred tax assets are recognized for the expected realization of available deductible temporary differences and net operating loss and tax credit carry forwards. ASC 740 requires companies to assess whether a valuation allowance should be established against deferred tax assets based on consideration of all available evidence using a “more likely than not” threshold. In making such assessments, the Company considers the expected reversals of our existing deferred tax liabilities within the applicable jurisdictions and carry forward periods, based on our existing Section 382 limitations. The Company does not consider deferred tax liabilities related to indefinite lived intangibles or tax deductible goodwill as a source of future taxable income. Additionally, the determination of the amount of deferred tax assets which are more likely than not to be realized is also dependent on projections of future earnings, which are subject to uncertainty and estimates that may change given economic conditions and other factors. A valuation allowance is recorded to reduce our deferred tax assets to the amount that is “more likely than not” to be realized based on the above methodology. The Company reviews the adequacy of the valuation allowance on an ongoing basis and adjusts our valuation allowance in the appropriate period, if applicable. The Company records liabilities for uncertain tax positions related to federal, state and foreign income taxes in accordance with ASC 740. These liabilities reflect the Company’s best estimate of its ultimate income tax liability based on the tax code, regulations, and pronouncements of the jurisdictions in which we do business. Estimating our ultimate tax liability may involve significant judgments regarding the application of complex tax regulations across many jurisdictions. If the Company’s actual results differ from estimated results, our effective tax rate and tax balances could be affected. As such, these estimates may require adjustment in the future as additional facts become known or as circumstances change. If applicable, the Company will adjust the income tax provision in the appropriate period. Stock-Based Employee Compensation The Company grants to our employees and directors options to purchase common stock at exercise prices equal to the quoted market values of the underlying stock at the time of each grant. The fair value of each option award as of the grant date is determined using the Black-Scholes option pricing valuation model in accordance with ASC 718, Compensation-Stock Compensation . In addition, the Company grants performance-based share equity awards that contain service, performance and market conditions. The performance conditions are assessed at each reporting period and compensation expense is recorded to reflect the probable attainment of each condition. The market conditions are valued using a Monte Carlo simulation model. The valuation is prepared with the assistance of a third-party specialist to estimate the grant date fair value of the award. The fair value of all stock awards is recognized in compensation expense on a straight-line basis over the requisite service period for awards expected to vest. Net Income (Loss) Per Common Share The Company computes net income (loss) per common share in accordance with ASC 260, Earnings Per Share . Basic net income (loss) per common share includes no dilution and is computed by dividing net loss attributable to common stockholders by the weighted average number of common shares outstanding for the period. Diluted net income (loss) per common share includes the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock.

New Accounting Standards	New Accounting Standards Recently Adopted Accounting Standards In November 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2015-17, Income Taxes (Topic 740), Balance Sheet Classification of Deferred Taxes . This standard eliminates the current requirement for organizations to present deferred tax assets and liabilities as current and noncurrent in a classified balance sheet. Instead, organizations will be required to classify all deferred tax assets and liabilities as noncurrent. The pronouncement is effective for annual reporting periods beginning after December 15, 2016, and interim periods within those annual periods. As permitted, the Company has elected to early-adopt these standards on a prospective basis beginning in the fourth quarter of fiscal 2015. Prior periods in our Consolidated Financial Statements were not retrospectively adjusted. In April 2015 and August 2015, the FASB issued ASU No. 2015-03, Interest-Imputation of Interest (Subtopic 835-30), Simplifying the Presentation of Debt Issuance Costs and ASU No. 2015-03 , Interest-Imputation of Interest (Suptopic 835-30), respectively. ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts and provides guidance on the application of these requirements to line-of-credit arrangements. As permitted, the Company has elected to early-adopt these standards in the fourth quarter of fiscal 2015. This guidance was applied on a retrospective basis. The impact of the early adoption on our Consolidated Balance Sheet for the year ended December 31, 2014 was a decrease to other assets and a decrease to long-term debt of $0.8 million and a decrease to other current assets and a decrease to the current portion of debt of $4 thousand . The adoption had no impact on the statement of earnings or statement of cash flows. The additional guidance provided in ASU 2015-15 had no material financial statement impact. Accounting Standards Issued Not Yet Adopted In September 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2015-16, Business Combinations (Topic 805), Simplifying the Accounting for Measurement-Period Adjustments . The new standard requires an entity recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The standard also requires that the acquirer record, in the same period's financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provision amounts, calculated as if the accounting had been completed at the acquisition date. For public companies, ASU 2015-16 is effective for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years. ASU 2015-16 is not expected to have a material effect on the Company's consolidated financial statements and footnote disclosures. In August 2014, the FASB issued new guidance related to the disclosures around going concern. The new standard provides guidance around management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Early adoption is permitted. The adoption of this standard is not expected to have an impact on our consolidated financial statements or disclosures. In May 2014, the FASB and International Accounting Standards Board ("IASB") issued ASU 2014-09 Revenue from Contracts with Customers (Topic 606), a converged standard on revenue recognition which supersedes previous revenue recognition guidance. Some of the main areas of transition to the new standard include, among others, transfer of control (revenue is recognized when a customer obtains control of a good or service), allocation of transaction price based on relative standalone selling price (entities that sell multiple goods or services in a single arrangement must allocate the consideration to each of those goods or services), contract costs (entities sometimes incur costs, such as sales commissions or mobilization activities, to obtain or fulfill a contract), and disclosures (extensive disclosures are required to provide greater insight into both revenue that has been recognized, and revenue that is expected to be recognized in the future from existing contracts). In August 2015, the FASB issued ASU 2015-14 Revenue from Contracts with Customers (Topic 606), Deferral of the Effective Date , which defers the effective date of the new standard by one year, resulting in the new standard being effective for fiscal years, and interim periods within those years, beginning after December 15, 2017 with early adoption as of the original effective date permitted. The Company will use one of two methods of adoption: (i) retrospective to each prior reporting period presented, with the option to elect certain practical expedients as defined within the standard; or (ii) retrospective with the cumulative effect of initially applying the standard recognized at the date of initial application inclusive of certain additional disclosures. The Company is currently evaluating and has not determined the impact of ASU 2014-09 on its consolidated financial statements.

Earnings Per Share [Abstract]
Net Loss Per Common Share	Net Income (Loss) Per Common Share Basic net income (loss) per common share is calculated using net income (loss) and the weighted-average number of shares outstanding during the reporting period. Diluted net income (loss) per common share includes the effect from the potential issuance of common stock, such as common stock issued pursuant to the exercise of stock options or vesting of restricted shares. During the first quarter of 2015, the Company issued an equity award with performance, service and market conditions. These awards will be included in basic shares outstanding once all criteria have been met and the shares have vested. Prior to the end of the vesting period, the number of contingently issuable shares included in diluted EPS is based on the number of shares, if any, that would be issuable under the terms of the arrangement if the end of the reporting period were the end of the contingency period, using the treasury stock method and assuming the result would be dilutive. As of December 31, 2015, the performance criteria for the first tranche was satisfied and the equity award has been included in the diluted share calculation. See Note 11, Stock-Based Compensation and Stockholders' Equity , for additional information on this award. During the years ended December 31, 2015 , 2014 and 2013, 1.6 million , 6.9 million and 7.7 million share-based awards, respectively, have been excluded from the calculation of diluted common shares because including those securities would have been anti-dilutive. The Company's potentially dilutive shares also include incremental shares issuable upon the conversion of the Senior Convertible Notes due August 15, 2018 ("2018 Notes"). Upon conversion or maturity of the 2018 Notes, the Company may settle the notes with either cash, shares of our common stock or a combination of cash and shares of our common stock, at our election. The Company has adopted a current policy to settle the principal amount in cash and any excess conversion value in shares of our common stock. Because the principal amount of the 2018 Notes will be settled in cash upon conversion, only the conversion spread relating to the 2018 Notes is included in our calculation of diluted net income per common share. When the market price of our stock exceeds the conversion price, as applicable, we will include, in the diluted net income per common share calculation, the effect of the additional shares that may be issued upon conversion using the treasury stock method. There were no incremental common shares from the 2018 Notes that were included in the calculation of diluted shares because the Company's common stock did not exceed the conversion price during the years ended December 31, 2015, 2014 and 2013. See Note 4, Long-term Debt , for information on these notes. The following table sets forth the computation of basic and diluted net loss per common share (in thousands, except per share amounts): 2015 2014 2013 Net income (loss) $ 89,961 $ (12,458 ) $ (65,664 ) Basic weighted average common shares 50,243 50,920 48,947 Dilutive effect of stock options 1,757 — — Dilutive effect of restricted shares 426 — — Dilutive effect of performance shares 16 — — Dilutive effect of the assumed conversion of the 2018 Notes — — — Diluted weighted average common shares 52,442 50,920 48,947 Basic earnings (loss) per share: Net income (loss) $ 1.79 $ (0.24 ) $ (1.34 ) Diluted income (loss) per share: Net income (loss) $ 1.72 $ (0.24 ) (1.34 )

Long-term Debt

Debt Disclosure [Abstract]
Long-term Debt	Long-term Debt 1% Senior Convertible Notes due August 15, 2018 In August 2013, the Company issued $258.8 million aggregate principal amount of 1.00% Senior Convertible Notes due August 15, 2018 ("2018 Notes"). The 2018 Notes bear interest at a rate of 1.00% per year, payable semiannually in arrears, on February 15 and August 15 of each year, beginning on February 15, 2014. The conversion price for the 2018 Notes is equivalent to an initial effective conversion price of approximately $35.00 per share of common stock. Proceeds, net of original issuance discounts of $252.3 million were received from the 2018 Notes. The net proceeds were used to pay down $208.0 million of the First Lien Term Loan and $43.0 million of the Revolving Credit Facility. The refinancing of the First Lien Term Loan was treated as debt extinguishment within the scope of ASC 470, Debt. As such, the Company recorded a $1.1 million loss during the year ended December 31, 2013, from accelerating debt issuance costs and loan origination discounts. The Company may not redeem the 2018 Notes prior to August 20, 2016 . On or after August 20, 2016, the Company may redeem for cash any or all of the 2018 Notes, at its option, if the last reported sale price of our common stock exceeds 130% of the applicable conversion price on each applicable trading day as defined by the indenture. The redemption price will equal 100% of the principal amount of the 2018 Notes to be redeemed, plus accrued and unpaid interest to, but not including, the redemption date. Holders of the 2018 Notes may also convert their notes at any time prior to May 15, 2018 if the sale price of our common stock exceeds 130% of the applicable conversion price on each applicable trading day as defined by the indenture. In addition, holders may also convert their 2018 Notes any time prior to May 15, 2018 , (i) if during the five business days after any five consecutive trading day period in which the trading price of the 2018 Notes was less than 98% of the product of the last reported sale price of the Company's common stock and the conversion rate, (ii) if the Company calls the 2018 Notes for redemption; or (iii) upon the occurrence of specified corporate events. Prior to August 20, 2016, the 2018 Notes are redeemable or convertible upon certain fundamental changes, as defined in the indenture, which may require the Company to purchase the 2018 Notes in whole or in part for cash at a price equal to 100% of the principal amount of the 2018 Notes to be purchased, plus any accrued and unpaid interest to, but not including, the purchase date. The 2018 Notes are senior unsecured obligations and will be effectively junior to any of the Company's existing and future secured indebtedness. The Company determined that the embedded conversion option in the 2018 Notes is not required to be separately accounted for as a derivative under Accounting Standards Codification ("ASC") 815, Derivatives and Hedging . The 2018 Notes are within the scope of ASC 470, Topic 20, Debt with Conversion and Other Options, which requires the Company to separate a liability component and an equity component from the proceeds received. The carrying amount of the liability component at the time of the transaction of $204.4 million was calculated by measuring the fair value of a similar debt instrument that does not have an associated equity component. The fair value of the liability component was subtracted from the initial proceeds and the remaining amount of $47.8 million was recorded as the equity component. The excess of the principal amount of the liability component over its carrying amount will be amortized to interest expense over the expected life of 5 years using the effective interest method. Upon conversion or maturity of the 2018 Notes, the Company may settle the notes with either cash, shares of its common stock or a combination of cash and shares of its common stock, at its election. The Company has adopted a current policy to settle the $258.8 million of principal amount in cash and any excess conversion value in shares of our common stock. Because the principal amount of the 2018 Notes will be settled in cash upon conversion, only the conversion spread relating to the 2018 Notes may be included in the Company's calculation of diluted net income per common share. When the market price of the Company's stock exceeds the conversion price, it will include, in the diluted net income per common share calculation, the effect of the additional shares that may be issued upon conversion using the treasury stock method. As such, the 2018 Notes have no impact on diluted net income per common share until the price of the Company's common stock exceeds the conversion price (approximately $35.00 per common share) of the 2018 Notes. As of December 31, 2015 and 2014, the carrying value of the debt and equity component was $228.0 million and $47.8 million and $217.8 million and $47.8 million , respectively. The unamortized debt discount of $30.7 million as of December 31, 2015 will be amortized over the remaining life of 2.6 years using the effective interest method. Credit Agreement On September 9, 2014, the Company entered into a Credit Agreement with JPMorgan Chase Bank, N.A. and SunTrust Bank, as co-syndication agents, Regions Bank, Fifth Third Bank, Bank of America, N.A., Barclays Bank plc, Wells Fargo Bank, National Association, Royal Bank of Canada, Deutsche Bank Securities Inc. and Compass Bank, as co-documentation agents, the lenders from time to time party thereto and JPMorgan Chase Bank, N.A., as administrative agent (the "Credit Agreement"). The Credit Agreement provides for (i) a five -year $200 million secured term loan facility (the “Term Loan”) and (ii) a five -year secured revolving credit facility that provides up to $150 million of revolving loans (the “Revolving Credit Facility”). The Credit Agreement replaced the First Lien Credit Agreement, dated as of October 27, 2011 amended and restated as of November 20, 2012, further amended and restated March 6, 2013, and further amended as of April 25, 2014 (the "Predecessor Credit Agreement"). The Company used the proceeds of the Term Loan and initially borrowed $109 million of loans under the Revolving Credit Facility, together with cash on hand, to repay existing loans under the Predecessor Credit Agreement in their entirety and to pay related fees and expenses. In connection with the repayment, the Company terminated the Predecessor Credit Agreement. The Term Loan and loans under the Revolving Credit Facility initially bore interest at a rate equal to either, at the Company’s option, the LIBOR rate plus an applicable margin equal to 2.25% per annum, or the prime lending rate plus an applicable margin equal to 1.25% per annum. The applicable margins for the Term Loan and loans under the Revolving Credit Facility are subject to reduction or increase based upon the Company’s consolidated first lien net leverage ratio as of the end of each fiscal quarter. Effective November 2015, the Company's interest rate on these loans was reduced to the LIBOR rate plus the applicable margin of 1.50% per annum or the prime lending rate plus an applicable margin equal to 0.50% per annum, as a result of reaching certain financial covenant ratios. During the quarters ended June 30, 2015 and September 30, 2015, respectively, the Company benefited from a 0.50% and 0.25% rate reduction on our Term Loan and Revolving Credit Facility resulting from our favorable financial covenant ratios resulting in an interest rate of LIBOR plus an applicable margin of 1.50% per annum as of December 31, 2015. The Company also benefited from a reduced commitment fee of 0.30% per annum on the actual daily amount by which the revolving credit commitment exceeds then-outstanding usage under the Revolving Credit Facility. In addition, the Company pays a letter of credit fee equal to the applicable margin that applies to LIBOR loans under the Revolving Credit Facility and a fronting fee of 0.125% per annum, calculated on the daily amount available to be drawn under each letter of credit issued under the Revolving Credit Facility. The Company is permitted to make voluntary prepayments with respect to the Revolving Credit Facility and the Term Loan at any time without payment of a premium. The Company is required to make mandatory prepayments of the Term Loan with (i) net cash proceeds from certain asset sales (subject to reinvestment rights) and (ii) net cash proceeds from certain issuances of debt. The Company is also required to maintain certain financial ratios under the Credit Agreement and there are customary covenants that limit the incurrence of debt, the payment of dividends, the disposition of assets, and making of certain payments. Substantially all of the Company's and certain of its domestic subsidiaries' tangible and intangible assets are pledged as collateral under the Credit Agreement. The refinancing of the Predecessor Credit Agreement was partially accounted for as debt extinguishment in accordance with ASC 470, Debt, with the remaining amounts not considered extinguished, treated as a modification of the existing credit agreement. As a result of the extinguishment, the Company recorded a $1.8 million loss for the portion of the debt that was extinguished from accelerating unamortized deferred financing fees and loan origination discounts during the year ended December 31, 2014. Approximately $3.7 million of additional loan origination discounts and deferred financing fees were capitalized in 2014 in connection with the refinancing. Predecessor Credit Agreement On October 27, 2011, the Company entered into credit facilities, pursuant to (i) the Predecessor Credit Agreement and (ii) a Second Lien Credit Agreement (the "Second Lien Credit Agreement"). The Predecessor Credit Agreement originally provided for (i) a six -year first lien term loan (the “Predecessor First Lien Term Loan”) and (ii) a five -year first lien revolving credit facility (the “Predecessor Revolving Credit Facility”). The Second Lien Credit Agreement originally provided for a seven -year second lien term loan (the “Second Lien Term Loan”). On March 6, 2013, the Company repriced its Predecessor Lien Term Loan and increased the outstanding balance to $660.0 million . In addition, the Company increased the maximum amount of available borrowings under the Predecessor Revolving Credit Facility to $70 million . The proceeds received from the additional Predecessor First Lien Term Loan were used to extinguish the Second Lien Term Loan's outstanding balance of $32.0 million . The repricing of the Predecessor First Lien Term Loan and the payoff of the Second Lien Term Loan, in connection with the issuance of the 2018 Notes discussed above, were both accounted for as debt extinguishments in accordance with ASC 470, Debt . As a result of the extinguishments, the Company recorded a $20.7 million lo ss from debt extinguishment from accelerating unamortized deferred financing fees and loan origination discounts during the twelve months ended December 31, 2013. Included in the loss is $7.2 million of prepayment penalties that were paid during the first quarter of 2013 related to the extinguishment of the Second Lien Term Loan and repricing of the Predecessor First Lien Term Loan. The Compan y has $143.0 million of av ailable borrowings under the Revolving Credit Facility as of December 31, 2015. In April 2015 and August 2015, the FASB issued ASU No. 2015-15, Interest-Imputation of Interest (Subtopic 835-30), Simplifying the Presentation of Debt Issuance Costs and ASU No. 2015-03 , Interest-Imputation of Interest (Suptopic 835-30), respectively. ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts and provides guidance on the application of these requirements to line-of-credit arrangements. The following table reflects the implementation of ASU 2015-03 in the year ended December 31, 2015. In addition, as required by ASU 2015-03, the 2014 debt issuance costs have been retrospectively adjusted to be presented in the balance sheet as a direct deduction from the carrying amount of the debt liability. The impact of the adoption for the year ended December 31, 2014 was a decrease to the Revolving Credit Facility of $0.4 million , a decrease to the Term Loan of $0.1 million , and a decrease to the Senior Convertible Notes of $0.3 million , for a total decrease in long-term debt of $0.8 million . Also, the current portion of debt was decreased $4 thousand for the year ended December 31, 2014. Outstanding long-term debt and the effective interest rates at December 31, 2015 and 2014 consist of the following (in thousands): December 31, December 31, Revolving Credit Facility maturing 2019, 1.71%, based on LIBOR plus 1.50%, less unamortized discount of $1,563 at December 31, 2015 $ 3,437 $ 92,013 Term Loan due 2019, 1.71%, based on LIBOR plus 1.50%, less unamortized discount of $1,391 at December 31, 2015, effective rate of 1.93% 191,109 196,940 Senior Convertible Notes, maturing 2018, 1.00%, less unamortized discount of $30,718 at December 31, 2015, effective rate of 5.88% 228,032 217,502 Total Outstanding Debt, less unamortized discount of $33,672 at December 31, 2015 422,578 506,455 Less: Current Portion of Long-Term Debt, less unamortized discount of $81 at December 31, 2015 (11,169 ) (6,193 ) Long-Term Portion, less unamortized discount of $33,591 at December 31, 2015 $ 411,409 $ 500,262 Debt discount and issuance costs The Company recorded $11.4 million , $10.9 million and $5.4 million of interest expense from amortizing debt issuance costs and discounts during the years ended December 31, 2015 , 2014 and 2013 , respectively. Total estimated principal payments due for the next five years as of December 31, 2015 are as follows (in thousands): 2016 $ 11,250 2017 16,250 2018 278,750 2019 150,000 2020 — Total principal payments $ 456,250 On August 15, 2018, the aggregate principal balance of the Senior Convertible Notes (the 2018 Notes) becomes due. The remaining principal requirements reflect quarterly payments under the Term Loan with the remaining balance payable in September 2019. The Revolving Credit Facility matures in September 2019.

Business Combinations	Business Combinations Acquisition of SnapNames On February 28, 2014, the Company completed the acquisition of substantially all of the assets and certain liabilities of SnapNames.com, Inc. ("SnapNames"), an Oregon corporation, from KeyDrive S.A., which primarily consisted of intangible assets, including trade names, customer relationships and developed technology. The activities of the acquired business include daily auctions, premium auctions, and brokerage transactions related to domain names (the "SnapNames Business"). The Company paid $7.4 million for this business during the first quarter of 2014. The Company also recorded a $0.5 million holdback liability which was paid to KeyDrive S. A. during the year ended December 31, 2015. The Company has accounted for the acquisition of the SnapNames Business using the acquisition method as required in ASC 805, Business Combinations ("ASC 805"). As such, fair values have been assigned to the assets acquired and liabilities assumed and the excess of the total purchase price over the fair value of the net assets acquired is recorded as goodwill. The Company, with the assistance of independent valuation professionals, has estimated the fair value of certain intangible assets. The goodwill recorded from this acquisition represents business benefits the Company anticipates realizing from optimizing resources and cross-sale opportunities. The goodwill from the acquisition is deductible for tax purposes. Acquisition of Scoot On July 31, 2014, the Company completed the acquisition of 100% of the equity interests in Touch Local Limited (“Scoot”), the operator of an online business directory network in the United Kingdom. The Company believes that the acquisition further enhances its position as a leading provider of online marketing and web services to small businesses and positions its local expansion in the United Kingdom. Consideration for the acquisition included $11.9 million , which is net of cash acquired, $11.0 million of which was paid to the sellers in July 2014 and $0.9 million that was placed in an escrow account for one year and subsequently released and paid on July 31, 2015. The Company also recorded a $0.9 million holdback liability that was also paid in July 2015. In addition, the Company issued an aggregate of 213,200 shares of Web.com common stock, with an aggregate acquisition date value of $5.7 million , to the sellers. Finally, $0.3 million of accounts receivable due from Scoot was forgiven by the Company, for total consideration of $18.7 million . The Company has also accounted for the acquisition of Scoot using the acquisition method as required in ASC 805. Based on the acquisition method of accounting, the consideration was allocated to the assets and liabilities acquired based on their fair values as of the acquisition date and the remaining amount of the purchase price allocation was recorded as goodwill. The goodwill represents business benefits the Company anticipates realizing from optimizing resources and cross-sale opportunities and is not deductible for tax purposes.

Fair Value Disclosures [Abstract]
Fair Value	Fair Value The Company defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company applies the following fair value hierarchy, which prioritizes the inputs used to measure fair value into three levels as follows: Level 1 -Quoted prices in active markets for identical assets or liabilities. Level 2 -Observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 -Inputs that are generally unobservable and typically reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability. The Company has financial assets and liabilities that are not required to be remeasured to fair value on a recurring basis. The Company’s cash and cash equivalents, accounts receivable, accounts payable, and accrued expenses approximates fair market value as of December 31, 2015 and December 31, 2014 due to the short maturity of these items. As of December 31, 2015 , the fair value and carrying value of the Company’s 2018 Notes totaled $243.2 million and $228.0 million , respectively. As of December 31, 2014 the fair value and carrying value of the Company's First Lien Term Loan and the Company's 2018 Notes was $237.7 million and $217.8 million , respectively. The fair value of the First Lien Term Loan and the 2018 Notes, including the equity component, were calculated by taking the quoted market price for the instruments multiplied by the principal amount. This is based on a Level 2 fair value hierarchy calculation obtained from quoted market prices for the Company’s long-term debt instruments that may not be actively traded at each respective period end. The Revolving Credit Facility's fair value as of December 31, 2014 also approximates the carrying value. The Revolving Credit Facility and Term Loan that were refinanced in September 2014 are variable rate debt instruments indexed to 1-Month LIBOR that resets monthly, as such, the fair value of the Term Loan and Revolving Credit Facility approximates the carrying value as of December 31, 2015.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	Stock-Based Compensation and Stockholders' Equity The Company records compensation expense for employee and director stock-based compensation plans based upon the fair value of the award in accordance with ASC 718, Compensation-Stock Compensation. Equity Incentive Plans At December 31, 2015 , the Company has the 2014 Equity Incentive Plan for the issuance of stock-based compensation, including but not limited to, common stock options and restricted shares to employees. In addition, the Company’s plan provides for grants of non-statutory stock options and restricted shares awards (“RSA’s”) to non-employee directors. The Company issues shares out of treasury stock, if available, otherwise new shares of common stock are issued upon the exercise of stock options and the granting of restricted shares. At December 31, 2015 , approximately 3.7 million shares remain available for future issuance under this plan. In addition, the Company has additional equity incentive plans that are established in conjunction with its acquisitions. These plans are considered one-time, inducement awards of incentive stock options, non-statutory stock options and restricted shares. Once the inducement awards are granted, no additional shares, including forfeitures and cancellations, are available for future grant under these plans. Incentive stock options and non-statutory stock options issued generally vest ratably over three to four years, are contingent upon continued employment and expire ten years from the grant date. Restricted share awards generally vest 25 percent each year over a four year period. The Board of Directors or a committee thereof, administers all of the equity incentive plans and establishes the terms of options granted, including the exercise price, the number of shares subject to individual option awards and the vesting period of options, within the limits set forth in the plans. Options have a maximum term of 10 years and vest as determined by the Board of Directors. Performance Shares During the first quarter of 2015, the Compensation Committee of the Board of Directors approved a performance share equity award. The targeted number of shares under a 100 percent payout scenario are 0.2 million common shares over the 3 years vesting period, with one-third vesting each year. The actual number of shares that may be earned and issued, if any, may range from 0-200% of the target number of shares granted. The range is based upon (1) the number of shares earned based upon the over achievement or under achievement of the financial measures for the annual performance period and (2) the number of shares earned being adjusted higher or lower depending on the performance of the Company's total shareholder return, compared against the Company's peer group. Compensation expense related to the performance share stock plan for the year ended December 31, 2015 , was approximately $1.0 million . As of December 31, 2015 , there was approximately $0.1 million of unrecognized compensation expense related to the 2015 tranche of performance shares, which is expected to be recognized over a weighted average period of 0.1 years . The 2015 tranche of the performance share award resulted in a payout of 159% of the target shares, or approximately 92 thousand shares. The unamortized expense for the 2016 and 2017 performance share award is not known as of December 31, 2015 as the material terms of the award have not been determined and approved by the Compensation Committee of the Board of Directors. Stock Options Compensation expense related to the Company's stock option plans were $10.4 million , $12.0 million and $10.0 million for the years ended December 31, 2015 , 2014 and 2013 , respectively. As of December 31, 2015 , the Company had $11.9 million of unrecognized compensation expense related to stock options, which is expected to be recognized over a weighted average period of 2.2 years . During the years ended December 31, 2015 , 2014 and 2013 , 0.7 million , 1.0 million and 1.6 million common shares were issued from options exercised, respectively. The total intrinsic value of options exercised during the years ended December 31, 2015 , 2014 , and 2013 was $7.4 million , $23.4 million , and $25.7 million , respectively. The fair value of shares vested during the years ended December 31, 2015 , 2014 , and 2013 was $11.3 million , $12.4 million , and $11.7 million , respectively. The weighted-average grant-date fair value of an option granted during the years ended December 31, 2015 , 2014 , and 2013 was $9.36 , $15.81 , and $10.01 , respectively. The fair value of each option award is estimated on the date of the grant using the Black-Scholes option valuation model and the assumptions noted in the following table. Expected volatility rates are based on the Company’s historical volatility on the date of the grant. The Company estimates the expected term based on the historical exercise experience of our employees, which we believe is representative of future behavior. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of the grant. Below are the assumption ranges used in calculating the fair value of options granted during the following periods: Year Ended December 31, 2015 2014 2013 Risk-free interest rate 1.52 - 1.60 % 1.51 - 1.69 % 0.70 - 1.40 % Dividend yield — % — % — % Expected life (in years) 4.96 - 4.99 4.95 - 4.98 5.07 - 5.31 Volatility 55 - 57 % 56 -62 % 69 - 70 % The following table summarizes option activity for all of the Company’s stock options: Shares Covered by Options Exercise Price per Share Weighted- Average Exercise Price Weighted- Average Remaining Contractual Term (in years) Aggregate Intrinsic Value (in thousands) Balance, December 31, 2014 5,670,270 $ 3.43 to $36.45 $ 14.60 Granted 642,625 $18.07 to $24.88 $ 18.89 Exercised (763,271 ) $ 3.43 to $21.95 $ 11.41 Forfeited (237,445 ) $8.73 to $36.45 $ 22.02 Expired (49,387 ) $5.66 to $33.78 $ 26.02 Balance, December 31, 2015 5,262,792 $ 3.43 to $36.45 $ 15.15 5.90 $ 34,927 Exercisable at December 31, 2015 4,085,563 $ 3.43 to $32.56 $ 13.15 5.21 $ 32,768 Price ranges of outstanding and exercisable options as of December 31, 2015 are summarized below: Outstanding Options Exercisable Options Exercise Price Number of Options Weighted- Average Remaining Life (Years) Weighted- Average Exercise Price Number of Options Weighted- Average Exercise Price $3.43 - $8.74 1,087,338 3.56 $ 6.54 1,087,338 $ 6.54 $8.90 - $13.24 1,056,227 3.72 $ 10.14 1,054,182 $ 10.13 $13.29 - $15.96 1,641,799 6.56 $ 14.68 1,334,642 $ 14.47 $17.07 - $32.56 1,463,628 8.42 $ 25.50 609,401 $ 27.31 $36.45 - $36.45 13,800 8.16 $ 36.45 — $ — 5,262,792 4,085,563 Restricted Stock Restricted stock is not transferable until vested.

Income Taxes	Income Taxes The provision (benefit) for income taxes consisted of the following for the years ended December 31, (in thousands): 2015 2014 2013 Current expense (benefit): Federal $ 1,000 $ 401 $ — State 835 223 (31 ) Foreign 147 676 489 Total current tax expense 1,982 1,300 458 Deferred expense (benefit): Federal (49,301 ) 17,395 16,679 State (820 ) 2,954 4,229 Foreign (121 ) (105 ) (39 ) Total deferred tax (benefit) expense (50,242 ) 20,244 20,869 Total income tax expense (benefit) $ (48,260 ) $ 21,544 $ 21,327 As of December 31, 2015 and 2014 , the Company had federal net operating loss carry forwards (“NOLs”) of $265.3 million and $315.4 million , respectively, which expire in varying amounts beginning in 2020 through 2033. Included in the amount of NOLs as of December 31, 2015 and 2014 is $74.0 million and $72.0 million of stock-based compensation tax deductions in excess of book compensation expense (“APIC NOLs”), respectively, which will be credited to additional paid-in-capital when such deductions reduce taxes payable as determined on a “with-and-without” basis. Accordingly, these APIC NOLs will reduce federal taxes payable if realized in future periods, but NOLs related to such benefits are not included in the table below. The NOLs are subject to various limitations under Section 382 of the Internal Revenue Code. Accordingly, the Company estimates that at least $137.7 million and $189.8 million of the NOLs at December 31, 2015 and 2014 , respectively, will be available during the carry forward period. The deferred tax asset related to the net federal NOL carry forward values of $137.7 million and $189.8 million related to December 31, 2015 and 2014 , respectively, is included in the table below. As of December 31, 2015 , the Company had state NOLs of $303.2 million , the substantial portion of which expires in varying amounts beginning in 2020 through 2035. As of December 31, 2014 , the Company had state NOLs of $327.0 million . As of December 31, 2015 and December 31, 2014, the Company had foreign NOLs in the United Kingdom of $63.8 million and $62.2 million , respectively, which do not expire. As of December 31, 2015 and 2014 , the Company had a Foreign Tax Credit (“FTC”) carry forward of $1.2 million . The FTCs are related to taxes paid in Canada and begin to expire in 2017 . As of December 31, 2015 and 2014 , the Company had Research & Development (“R&D”) Tax Credit carry forwards of $0.5 million . The R&D credits begin to expire in 2028 . As of December 31, 2015 and 2014 , the Company had Alternative Minimum Tax (“AMT”) Credit carry forwards of approximately $3.0 million and $2.0 million , respectively, which do not expire. In establishing its deferred tax assets and liabilities, the Company makes judgments and interpretations based on the enacted tax laws and published tax guidance that are applicable to its operations. Deferred tax assets and liabilities are measured and recorded using currently enacted tax rates, which the Company expects will apply to taxable income in the years in which those temporary differences are recovered or settled. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of the Company’s deferred tax assets and liabilities are as follows at December 31 (in thousands): 2015 2014 Deferred tax assets: Current: NOLs $ — $ 19,271 Deferred revenue — 40,022 Other current deferred tax assets — 5,176 — 64,469 Less: valuation allowance — (30,761 ) Net current deferred tax assets — 33,708 Noncurrent: Deferred revenue 74,265 33,543 NOLs 74,121 71,673 Other deferred tax assets 26,284 14,710 174,670 119,926 Less: valuation allowance (26,581 ) (62,753 ) Net noncurrent deferred tax assets 148,089 57,173 Deferred tax liabilities: Current: Other liabilities — 10,232 Total current deferred tax liabilities — 10,232 Noncurrent: Intangible basis 158,788 147,543 Discount on 2018 Notes 10,966 14,249 Other liabilities 15,942 6,734 Total noncurrent deferred tax liabilities 185,696 168,526 Net current deferred tax asset — 23,750 Net current deferred tax liability — (274 ) Net noncurrent deferred tax asset 233 150 Net noncurrent deferred tax liability (37,840 ) (111,503 ) Net deferred tax liability $ (37,607 ) $ (87,877 ) In 2015 balances above were classified as noncurrent pursuant to the early adoption of ASU No. 2015-17. Please refer to Note 2, New Accounting Standards for discussion. In 2014, noncurrent DTLs increased $0.5 million , related to the Scoot acquisition, consisting of $0.6 million recorded at the purchase date, offset by $0.1 million associated with foreign currency translation adjustments during 2014 recorded in AOCI. The valuation allowance decreased by $66.9 million during the year ended December 31, 2015. In December 2015, after weighing all evidence available, the Company determined that it was more likely than not that the Company would be able to realize substantially all its net U.S. Federal deferred tax assets and a portion of its net U.S. state deferred tax assets. As a result, the Company reversed $68.8 million of its beginning of the year valuation allowance related to these deferred tax assets, which was partially offset by current year increases of $1.9 million related to certain foreign and state deferred tax assets for which it was determined that a valuation allowance was still required. The positive evidence that outweighed the negative evidence used in the Company’s assessment of the portion of the valuation allowance released in the fourth quarter of 2015 included, but was not limited to, the following: • The Company was no longer in a 3-year cumulative pre-tax book loss position as of the fourth quarter of 2015; • Strong positive trend in financial performance over the last two fiscal years, including each of the previous four quarters; and • Forecasted 2016 and future period taxable income. During the year ended December 31, 2014, the valuation allowance increased by $25.2 million . The change in valuation allowance for 2014 includes a net increase of $11.2 million related to the Scoot acquisition, consisting of $11.6 million recorded at the purchase date, an increase of $0.9 million related to foreign currency translation adjustments and a $0.5 million decrease related to activity subsequent to the purchase date. The change in valuation allowance for 2013 includes a decrease of $18.4 million that was recorded as an adjustment to APIC related to the initial recognition of the tax basis difference associated with the 2018 Notes. The valuation allowance at December 31, 2015 of $26.6 million includes $12.2 million and $13.2 million related to foreign and certain state net deferred tax assets, respectively, and $1.2 million related to its U.S. Federal FTC carry forwards, that are not more likely than not to be realized based on the expected reversals of our DTLs and estimated future taxable income within the applicable carry forward periods. The Company will continue to evaluate its ability to realize our deferred tax assets. If future evidence suggests that any changes are required to reflect the amount of our deferred tax asset that is more likely than not to be realized, the Company will adjust its valuation allowance, as needed in the appropriate period. The provision (benefit) for income taxes differs from the amount computed by applying the statutory U.S. federal income tax rates as a result of the following for the years ended December 31: 2015 2014 2013 U.S. statutory rate 35.0 % 34.0 % (34.0 ) % State income taxes (net of federal tax benefit) 2.8 0.3 (7.8 ) Stock-based compensation 4.7 17.5 1.7 Change in valuation allowance (160.5 ) 159.2 74.3 Prior year adjustments (0.4 ) 0.1 1.7 Foreign rate differential 2.0 6.9 — Non-deductible compensation costs 2.0 10.7 3.1 Change in tax rate (0.6 ) 3.9 9.4 Unremitted foreign earnings and profits 0.7 3.5 (0.7 ) Other (1.5 ) 1 0.4 Income tax expense (benefit) (115.8 ) % 237.1 % 48.1 % The Company applies ASC 740, Income Taxes, which clarifies the accounting for uncertainty in income tax positions recognized in financial statements. The Company is subject to audit by the IRS and various states generally for all years since inception. The Company is subject to audit in Canada generally for four years and the United Kingdom since its inception. The IRS concluded an examination of the Company's 2011 U.S. income tax return in the first quarter of 2015 without any material impact on the consolidated financial statements. The Company’s policy is that it recognizes interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense. The Company’s unrecognized tax benefits are summarized as follows (in thousands): Balance at December 31, 2012 $ 2,476 Additions in unrecognized tax benefits – prior year tax positions 337 Additions in unrecognized tax benefits – current year tax positions 287 Foreign exchange gains and losses — Balance at December 31, 2013 $ 3,100 Additions in unrecognized tax benefits – prior year tax positions 31 Additions in unrecognized tax benefits – current year tax positions 300 Balance at December 31, 2014 $ 3,431 Additions in unrecognized tax benefits – prior year tax positions 73 Additions in unrecognized tax benefits – current year tax positions 300 Settlements (62 ) Lapse of statute of limitations (248 ) Balance at December 31, 2015 $ 3,494 As of December 31, 2015 and 2014 , the Company had $2.9 million and $0.7 million , respectively, of total unrecognized tax benefits, which could favorably affect the effective rate. In addition, the Company recorded net interest and penalties benefit of $0.2 million , and net expense of $0.1 million , and $0.1 million during 2015 , 2014 , and 2013 , respectively, on the unrecognized tax benefits. The total amount of accrued interest and penalties as of December 31, 2015 and December 31, 2014 , was $0.1 million and $0.4 million , respectively. The Company’s undistributed foreign earnings of $2.7 million as of December 31, 2015 related to its Canadian subsidiary, Web.com Canada, Inc., and its Argentine subsidiary, NCIT S.R.L., are considered to be indefinitely reinvested into these foreign jurisdictions. Accordingly, the Company has not provided deferred taxes on these earnings. If these earnings were repatriated, the incremental US tax liability would not be material given the Company’s current US tax position.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Company	Description of Company Web.com Group, Inc. ("Web.com" or "the Company") provides a full range of Internet services to small businesses to help them compete and succeed online. Web.com meets the needs of small businesses anywhere along their lifecycle with affordable, subscription-based solutions including domains, hosting, website design and management, search engine optimization, online marketing campaigns, local sales leads, social media, mobile products and eCommerce solutions. The Company has reviewed the criteria of Accounting Standards Codification (“ASC”) 280-10, Segment Reporting, and has determined that the Company is comprised of only one segment, web services and products.
Use of Estimates	Use of Estimates The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
Foreign Currency Translation	Foreign Currency Translation The functional currency of the Company’s United Kingdom-based operations acquired in July 2014 is the British Pound. The Company translates the financial statements of this subsidiary to U.S. dollars using month-end rates of exchange for assets and liabilities, historical rates of exchange for equity and average rates of exchange for revenues, costs, and expenses. Translation gains and losses are recorded in accumulated other comprehensive (loss) income as a component of stockholders’ equity. In addition, the Company’s foreign operations include a customer service center and an outbound sales center in Canada and a technology center in Argentina. The Company records foreign currency transaction gains and losses, realized and unrealized and measurement of local currencies of these foreign subsidiaries where the foreign currency is different from the local currency in the consolidated statements of income (loss). During the years ended December 31, 2015, 2014 and 2013, the Company recorded approximately $0.4 million , $0.3 million and $0.2 million , respectively.
Principles of Consolidation	Principles of Consolidation The Company’s consolidated financial statements include the assets, liabilities and the operating results of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated.
Revenue Recognition and Deferred Revenue	Revenue Recognition and Deferred Revenue The Company recognizes revenue in accordance with ASC 605, Revenue Recognition . The Company recognizes revenue when all of the following conditions are satisfied: (1) there is persuasive evidence of an arrangement; (2) the service has been provided to the customer; (3) the amount of fees to be paid by the customer is fixed or determinable; and (4) the collection of our fees is reasonably assured. Thus, the Company recognizes subscription revenue on a daily basis, as services are provided. Customers are billed for the subscription on a monthly, quarterly, semi-annual, annual or on a multi-year basis, at the customer’s option. For all of the Company’s customers, regardless of the method the Company uses to bill them, subscription revenue is recorded as deferred revenue in the accompanying consolidated balance sheets. As services are performed, the Company recognizes subscription revenue on a daily basis over the applicable service period. When the Company provides a free trial period, the Company does not begin to recognize subscription revenue until the trial period has ended and the customer has been billed for the services. The Company accounts for our multi-element arrangements in accordance with ASC 605-25, Revenue Recognition: Multiple-Element Arrangement. The Company may sell multiple products or services to customers at the same time. For example, we may design a customer website and separately offer other services such as hosting and marketing or a customer may combine a domain registration with other services such as private registration or e-mail. In accordance with ASC 605-25, each element is accounted for as a separate unit of accounting provided the following criteria is met: the delivered products or services has value to the customer on a standalone basis; and for an arrangement that includes a general right of return relative to the delivered products or services, delivery or performance of the undelivered product or service is considered probable and is substantially controlled by the Company. The Company considers a deliverable to have standalone value if the product or service is sold separately by us or another vendor or could be resold by the customer. Our products and services do not include a general right of return relative to the delivered products. In cases where the delivered products or services do not meet the separate unit of accounting criteria, the deliverables are combined and treated as one single unit of accounting for revenue recognition. The Company assigns value to the separate units of accounting in multiple-element arrangements using the relative selling price method which is calculated by taking the standalone selling price of each unit to the total selling price of the arrangement, multiplied by the total sales price. Typically, the deliverables within multiple-element arrangements are provided over the same service period, and therefore revenue is recognized over the same period. To determine the selling price in multiple-element arrangements, the Company establishes vendor-specific objective evidence of the selling price using the price of the deliverable when sold separately. If we are unable to determine the selling price because vendor-specific objective evidence does not exist, the Company will first look to third party evidence, and if that is not sufficient, it will determine an estimated sales price through consultation with and approval by the Company’s management, taking into consideration the Company’s relative costs, target profit margins, and any other information gathered during this process. The Company incurs direct costs, primarily related to outbound and inbound sales call centers, to acquire new customers. Frequently, these new customers purchase products that result in the deferral of revenue by the Company. All direct costs related to acquiring new customers are expensed in the period incurred and not deferred over the related deferred revenue contract term.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include cash on hand and bank demand deposit accounts. For purposes of presentation in the Consolidated Balance Sheets, the Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents.
Concentrations of Credit Risk	Concentrations of Credit Risk Financial instruments that potentially subject the Company to concentration of credit risk consist principally of cash and cash equivalents and trade receivables. The Company invests its cash in cash and credit instruments of highly rated financial institutions; three institutions hold 95% of the Company's total cash and cash equivalents. Concentrations of credit risk with respect to trade accounts receivable are limited due to the large number of customers comprising the Company’s customer base and their geographic dispersion. The Company has not incurred any significant credit related losses.
Accounts Receivable	Accounts Receivable Accounts receivable are recorded on the balance sheet at net realizable value. The Company’s management uses historical collection percentages and customer-specific information, when available, to estimate the amount of trade receivables that are uncollectible and establishes reserves for uncollectible balances based on this information. Generally receivables are classified as past due after 60 days . Trade receivables are written off once collection efforts are exhausted. The Company does not generally require deposits or other collateral from customers. Bad debt expense reported in operating expenses excludes provisions made to the allowance for doubtful accounts for anticipated refunds and automated clearinghouse returns that are recorded as an adjustment to revenue. Included in the accounts receivable line item in the Consolidated Balance Sheets as of the year ended December 31, 2015 and 2014 is approximately $1.1 million and $2.4 million , respectively, of miscellaneous receivables primarily due from the Canadian government for job creation incentive rebates and for sales and use tax.
Deferred Expenses	Deferred Expenses Deferred expenses primarily consist of prepaid domain name registry fees that are paid in full at the time a domain name is registered. The registry fees are recognized on a straight-line basis over the term of the domain registration period.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets The Company continued to perform the quantitative tests to determine if it is more likely than not that the carrying value of our goodwill and indefinite-lived intangible assets are impaired for our annual test at December 31, 2015 . The Company tests goodwill and intangible assets for impairment using one reporting unit. A market approach is used to test goodwill for impairment, while our intangible asset test uses the income approach. The following is not a complete discussion of the Company’s calculations, but outlines the general assumptions and steps for testing goodwill and intangible assets for impairment: Goodwill The first step involves comparing the fair value of our reporting unit to its carrying value, including goodwill. The Company uses a market capitalization approach after considering an estimated control premium. If the carrying value exceeds its fair value, the second step of the test is performed by comparing the carrying value of goodwill to its implied fair value. An impairment charge is recognized for the excess of the carrying value over its implied fair value. Intangible Assets The Company estimates the fair value of indefinite-lived intangibles using the relief-from-royalty method, a form of the income approach. It is based on the principle that ownership of the intangible asset relieves the owner of the need to pay a royalty to another party in exchange for rights to use the asset. Key assumptions in estimating the fair value include, among other items, forecasted revenue, royalty rates, tax rate, and the benefit of tax amortization. The Company employs a weighted-average cost of capital approach to determine the discount rates used in our projections. The determination of the discount rate includes certain factors such as, but not limited to, the risk-free rate of return, market risk, size premium, and the overall level of inherent risk. If the carrying value of the intangibles exceeds its fair value, an impairment charge is recognized. The results of these analyses indicated that the Company’s goodwill and indefinite-lived intangible assets were not impaired at December 31, 2015 .
Research and Development Costs	Technology and Development Costs The Company expenses technology and development costs as incurred.
Property and Equipment	Property and Equipment Property and equipment, including software, are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are provided over the estimated useful lives of the assets using the straight-line method. Depreciation expense includes the amortization of assets recorded under capital leases. The asset lives used are presented in the table below: Average Life in Years Computer equipment 3 - 5 Software 2 - 3 Furniture and fixtures 5 Other equipment 5 - 6 Buildings 30 Building improvements 15 Leasehold improvements Shorter of asset’s life
Advertising	Advertising Advertising costs are expensed as incurred. Included in advertising are general marketing, corporate sponsorships as well as online marketing and banner advertisements.
Income Taxes	Income Taxes The Company accounts for income taxes under the provisions of ASC 740, Income Taxes , using the liability method. ASC 740 requires recognition of deferred tax liabilities and assets for the expected future tax consequences of events that have been included in the financial statements or tax returns. Under this method, deferred tax liabilities and assets are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the difference is expected to reverse. Further, deferred tax assets are recognized for the expected realization of available deductible temporary differences and net operating loss and tax credit carry forwards. ASC 740 requires companies to assess whether a valuation allowance should be established against deferred tax assets based on consideration of all available evidence using a “more likely than not” threshold. In making such assessments, the Company considers the expected reversals of our existing deferred tax liabilities within the applicable jurisdictions and carry forward periods, based on our existing Section 382 limitations. The Company does not consider deferred tax liabilities related to indefinite lived intangibles or tax deductible goodwill as a source of future taxable income. Additionally, the determination of the amount of deferred tax assets which are more likely than not to be realized is also dependent on projections of future earnings, which are subject to uncertainty and estimates that may change given economic conditions and other factors. A valuation allowance is recorded to reduce our deferred tax assets to the amount that is “more likely than not” to be realized based on the above methodology. The Company reviews the adequacy of the valuation allowance on an ongoing basis and adjusts our valuation allowance in the appropriate period, if applicable. The Company records liabilities for uncertain tax positions related to federal, state and foreign income taxes in accordance with ASC 740. These liabilities reflect the Company’s best estimate of its ultimate income tax liability based on the tax code, regulations, and pronouncements of the jurisdictions in which we do business. Estimating our ultimate tax liability may involve significant judgments regarding the application of complex tax regulations across many jurisdictions. If the Company’s actual results differ from estimated results, our effective tax rate and tax balances could be affected. As such, these estimates may require adjustment in the future as additional facts become known or as circumstances change. If applicable, the Company will adjust the income tax provision in the appropriate period.
Stock-Based Employee Compensation	Stock-Based Employee Compensation The Company grants to our employees and directors options to purchase common stock at exercise prices equal to the quoted market values of the underlying stock at the time of each grant. The fair value of each option award as of the grant date is determined using the Black-Scholes option pricing valuation model in accordance with ASC 718, Compensation-Stock Compensation . In addition, the Company grants performance-based share equity awards that contain service, performance and market conditions. The performance conditions are assessed at each reporting period and compensation expense is recorded to reflect the probable attainment of each condition. The market conditions are valued using a Monte Carlo simulation model. The valuation is prepared with the assistance of a third-party specialist to estimate the grant date fair value of the award. The fair value of all stock awards is recognized in compensation expense on a straight-line basis over the requisite service period for awards expected to vest.
Net Income (Loss) Per Common Share	Net Income (Loss) Per Common Share The Company computes net income (loss) per common share in accordance with ASC 260, Earnings Per Share . Basic net income (loss) per common share includes no dilution and is computed by dividing net loss attributable to common stockholders by the weighted average number of common shares outstanding for the period. Diluted net income (loss) per common share includes the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock.
