Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Background	Organization and Background Organization We are the sole managing member of Desert Newco, and as a result, we consolidate its financial results and report non-controlling interests representing the economic interests held by its other members. Non-controlling interests excludes any net income (loss) attributable directly to GoDaddy Inc. We owned approximately 92% of Desert Newco's limited liability company units (LLC Units) as of June 30, 2018 . Basis of Presentation Our financial statements have been prepared in accordance with generally accepted accounting principles in the United States (GAAP), and include our accounts and the accounts of our subsidiaries. All material intercompany accounts and transactions have been eliminated. Our interim financial statements are unaudited, and in our opinion, include all adjustments of a normal recurring nature necessary for the fair presentation of the periods presented. The results for the interim periods are not necessarily indicative of the results to be expected for any subsequent period or for the year ending December 31, 2018 . These financial statements should be read in conjunction with our audited consolidated financial statements and related notes included in our Annual Report on Form 10-K for the year ended December 31, 2017 (the 2017 Form 10-K). Prior Period Reclassifications Reclassifications of certain immaterial prior period amounts have been made to conform to the current period presentation. Use of Estimates GAAP requires us to make estimates and assumptions affecting amounts reported in our financial statements. Our more significant estimates include: • the determination of the relative stand-alone selling price of the indicated performance obligations included in revenue arrangements with multiple performance obligations; • the fair value of assets acquired and liabilities assumed in business acquisitions; • the assessment of recoverability of long-lived assets, including property and equipment, goodwill and intangible assets; • the estimated reserve for refunds; • the estimated useful lives of intangible and depreciable assets; • the grant date fair value of equity-based awards; • the fair value of financial instruments; • the recognition, measurement and valuation of current and deferred income taxes; • the recognition and measurement of amounts payable under TRAs or as tax distributions to Desert Newco's owners; and • the recognition and measurement of loss contingencies, indirect tax liabilities and certain accrued liabilities. We periodically evaluate these estimates and adjust prospectively, if necessary. We believe our estimates and assumptions are reasonable; however, actual results may differ from our estimates. Segment and Reporting Unit As of June 30, 2018 , our chief operating decision maker function was comprised of our Chief Executive Officer who reviews financial information presented on a consolidated basis for purposes of allocating resources and evaluating financial performance for the entire company. Accordingly, we have a single operating segment and reporting unit.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Revenue Recognition Adoption of New Standard on Revenue from Contracts with Customers On January 1, 2018, we adopted the Financial Accounting Standards Board's (FASB) new revenue recognition standard using the modified retrospective method applied to those contracts not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under the new standard, while prior period amounts were not adjusted and continue to be reported in accordance with our historic accounting. The adoption of the new standard did not have a material impact to our financial statements. Revenue Recognition Revenue is recognized when control of the promised services is transferred to our customers, in an amount reflecting the consideration we expect to be entitled to in exchange for those services. We typically receive payment at the time of sale, the purpose of which is to provide our customers with a simplified and predictable way of purchasing our services. We have determined that our contracts do not include a significant financing component. Payments received in advance of our performance are recorded as deferred revenue. Revenue is recognized net of allowances for returns and applicable transaction-based taxes collected from customers. Our products are generally sold with a right of return within our policy, which are accounted for as variable consideration when estimating the amount of revenue to recognize. Refunds are estimated at contract inception using the expected value method based on historical refund experience and updated each reporting period as additional information becomes available and only to the extent it is probable a significant reversal of any incremental revenue will not occur. Refunds result in a reduced amount of revenue recognized over the contract term of the applicable product or service. Our revenue is categorized and disaggregated as reflected in our statements of operations, as follows: Domains . Domains revenue primarily consists of domain registrations and renewals, domain privacy, domain application fees, domain back-orders, aftermarket domain sales and fee surcharges paid to ICANN. Consideration is recorded as deferred revenue when received, which is typically at the time of sale, and revenue, other than for aftermarket domain sales, is recognized over the period in which the performance obligations are satisfied, which is generally over the contract term. Aftermarket domain revenue is recognized when ownership of the domain is transferred to the buyer. Hosting and presence . Hosting and presence revenue primarily consists of website hosting products, website building products and services, website security products, an online shopping cart and online visibility products. Consideration is recorded as deferred revenue when received, which is typically at the time of sale, and revenue is recognized over the period in which the performance obligations are satisfied, which is generally over the contract term. Business applications . Business applications revenue primarily consists of third-party productivity applications, email accounts and email marketing tools. Consideration is recorded as deferred revenue when received, which is typically at the time of sale, and revenue is recognized over the period in which the performance obligations are satisfied, which is generally over the contract term. See Note 6 for additional information regarding our deferred revenue. See Note 14 for our revenue disaggregated by geography. Performance Obligations Our contracts with customers may include multiple performance obligations, including a combination of some or all of the following products or services: domain registrations, website hosting products, website building products and services, website security products and other cloud-based products. Judgment may be required in determining whether products or services are considered distinct performance obligations that should be accounted for separately or as one combined performance obligation. Revenue is recognized over the period in which the performance obligations are satisfied, which is generally over the contract term. For each domain registration or renewal we provide, we have one performance obligation to our customers consisting of two promises: 1) to ensure the exclusive use of the domain during the applicable registration term and 2) to ensure the domain is accessible and appropriately directed to its underlying content. After the contract term expires, unless renewed, the customer can no longer access or use the domain. We have determined these promises are not distinct within the context of our contracts as they are highly interdependent and interrelated and are inputs to a combined benefit. Accordingly, we concluded that each domain registration or renewal represents one service offering and is a single performance obligation. We may also offer specific arrangements, such as GoCentral, in which we include promises to transfer multiple performance obligations in a single service offering. For such arrangements, we allocate the transaction price to each of the underlying distinct performance obligations based on its relative stand-alone selling price (SSP), as described below. We have determined that generally each of our other products and services constitutes an individual service offering to our customers, and therefore have concluded that each is a single performance obligation. For arrangements with multiple performance obligations, we allocate revenue to each distinct performance obligation based on its relative SSP. We use judgment to determine SSP based on prices charged to customers for individual products and services, taking into consideration factors including historical and expected discounting practices, the size, volume and term length of transactions, customer demographics, the geographic areas in which our products and services are sold and our overall go-to-market strategy. Principal versus Agent Considerations We sell our products and services directly to customers and also through a network of resellers. In certain cases, we act as a reseller of products provided by others. The determination of gross or net revenue recognition is reviewed on a product-by-product basis and is dependent on our determination as to whether we act as principal or agent in the transaction. Revenue associated with sales through our network of resellers, for certain aftermarket domain sales and for third-party offerings is recorded on a gross basis as we have determined that we control the product before transferring it to end customers. Assets Recognized from Contract Costs Commissions paid to our resellers represent an incremental cost of obtaining a contract with a customer. We capitalize and amortize such amounts to cost of revenue consistent with the pattern of transfer of the service to which the asset relates. Amounts capitalized and amortized were not material during any of the periods presented. Fees paid to various registries at the inception of a domain registration or renewal represent costs to fulfill a contract. We capitalize and amortize these prepaid domain name registry fees to cost of revenue consistent with the pattern of transfer of the service to which the asset relates. During the three months ended June 30, 2018 and 2017, amortization expense of such asset was $148.7 million and $138.6 million , respectively. During the six months ended June 30, 2018 and 2017, amortization expense of such asset was $294.0 million and $264.4 million , respectively. No other material contract costs were capitalized during any of the periods presented.

No material adjustments were made to the fair values of our Level 3 contingent consideration liabilities during any of the periods presented. We have no other material assets or liabilities measured at fair value on a recurring basis. Recent Accounting Pronouncements In February 2016 , the FASB issued new guidance related to accounting for leases. The new standard requires the recognition of assets and liabilities arising from lease transactions on the balance sheet and the disclosure of key information about leasing arrangements. For leases with a term of 12 months or less, a lessee can make an accounting policy election by class of underlying asset to not recognize an asset and corresponding liability. We will adopt the new standard on January 1, 2019 . Lessees will be required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. While we continue to evaluate the effect of adopting this guidance, we expect the accounting for our operating leases to be the most significant change as a result of the new guidance. We will recognize right-of-use assets and lease liabilities in our consolidated balance sheets upon adoption, which will increase our total assets and liabilities. In June 2016 , the FASB issued new guidance for the accounting for credit losses on instruments that will require entities to measure all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions and reasonable supportable forecasts. This replaces the existing incurred loss model and is applicable to the measurement of credit losses on financial instruments measured at amortized cost and also applies to some off-balance sheet credit exposures. The guidance is effective for annual and interim reporting periods beginning after December 15, 2019 , with early adoption permitted. We are currently evaluating the timing of our adoption and the expected impact of this new guidance. In November 2016 , the FASB issued new guidance requiring amounts generally described as restricted cash and restricted cash equivalents to be included with cash and cash equivalents when reconciling the amounts shown on the statement of cash flows. Our adoption of this new guidance on January 1, 2018 did not have a material impact. In January 2017 , the FASB issued new guidance simplifying the goodwill impairment test, eliminating the requirement for an entity to determine the fair value of its assets and liabilities (including unrecognized assets and liabilities) at the impairment testing date following the procedure that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Instead, an entity will be required to perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity will be required to recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to the reporting unit. The guidance is effective for annual and interim reporting periods beginning after December 15, 2019 , with early adoption permitted. We are currently evaluating the timing of our adoption and the expected impact of this new guidance. In May 2017 , the FASB issued new guidance to amend the scope of modification accounting for share-based payment arrangements. The amendment provides guidance on the types of changes to the terms or conditions of share-based payment awards which would require an entity to apply modification accounting. Our adoption of this new guidance on January 1, 2018 did not have a material impact. In June 2018 , the FASB issued new guidance to simplify the accounting for nonemployee share-based payment transactions, aligning most of the guidance with the requirements for share-based payments granted to employees. This guidance is effective for annual and interim reporting periods beginning after December 15, 2018 , with early adoption permitted. We are currently evaluating the timing of our adoption and the expected impact of this new guidance.

Stockholders' Equity	Stockholders’ Equity Secondary Offerings We have completed two underwritten public offerings in which certain stockholders, including KKR, SLP, YAM and certain of our executive officers, sold shares of our Class A common stock. We did not sell any shares in these offerings and did not receive any proceeds from the shares sold by the selling stockholders. Each offering included the exchange of LLC Units (together with the corresponding shares of Class B common stock) for Class A common stock by the selling stockholders, which resulted in increases in additional paid-in capital, with offsetting reductions in non-controlling interests, and material increases to the liability under the TRAs (see Note 12 ).

Equity-Based Compensation Plans	Equity-Based Compensation Plans As of December 31, 2017 , 16,024 shares of Class A common stock were available for issuance as future awards under the 2015 Equity Incentive Plan (the 2015 Plan). On January 1, 2018 , an additional 6,720 shares were reserved for issuance pursuant to the automatic increase provisions of the 2015 Plan. As of June 30, 2018 , 19,876 shares were available for issuance as future awards under the 2015 Plan. As of December 31, 2017 , 2,551 shares of Class A common stock were available for issuance under the 2015 Employee Stock Purchase Plan (the ESPP). On January 1, 2018 , an additional 1,000 shares were reserved for issuance pursuant to the ESPP. As of June 30, 2018 , 3,265 shares were available for issuance under the ESPP. We grant options at exercise prices equal to the fair market value of our Class A common stock on the grant date. We grant both options and restricted stock units (RSUs) vesting solely upon the continued employment of the recipient as well as awards vesting upon the achievement of annual or cumulative financial-based targets. We recognize the grant date fair value of equity-based awards as compensation expense over the required service period of each award, taking into account the probability of our achievement of associated performance targets.

We currently believe the performance targets related to the vesting of performance awards will be achieved. If such targets are not achieved, or are subsequently determined to not be probable of being achieved, we will not recognize any compensation expense for performance awards not expected to vest, and will reverse any previously recognized expense on such awards.

Credit Facility Our secured credit agreement (the Credit Facility) includes an aggregate of $2,497.5 million in seven -year term loans (the Term Loans) and a $200.0 million five -year revolving credit facility (the Revolving Credit Loan). The Term Loans mature on February 15, 2024 and bear interest at a rate equal to, at our option, either (a) LIBOR plus 2.25% per annum or (b) 1.25% per annum plus the highest of (i) the Federal Funds Rate plus 0.5% , (ii) the Prime Rate or (iii) one-month LIBOR plus 1.0% . We are eligible for a 0.25% reduction in the interest rate margins upon improvement in our corporate credit rating. A portion of the Term Loans are hedged by an interest rate swap. See Note 9 for discussion of this hedging instrument. The Revolving Credit Loan matures on February 15, 2022 and bears interest at a rate equal to, at our option, either (a) LIBOR plus a margin ranging from 2.00% to 2.50% per annum or (b) the higher of (i) the Federal Funds Rate plus 0.5% , (ii) the Prime Rate or (iii) the one-month LIBOR rate plus 1.0% plus a margin ranging from 1.00% to 1.50% per annum, with the margins determined based on our first lien net leverage ratio. At June 30, 2018 , we had $200.0 million available for borrowing under the Revolving Credit Loan and were not in violation of any covenants of the Credit Facility. The estimated fair value of the Term Loans was $2,479.1 million at June 30, 2018 based on observable market prices for these loans, which are traded in a less active market and therefore classified as a Level 2 fair value measurement. Future Debt Maturities Aggregate principal payments, exclusive of any unamortized original issue discount and debt issuance costs, due on long-term debt as of June 30, 2018 are as follows: Year Ending December 31: 2018 (remainder of) $ 12.5 2019 25.0 2020 25.0 2021 25.0 2022 25.0 Thereafter 2,357.3 $ 2,469.8

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging	Derivatives and Hedging We are exposed to changes in foreign currency exchange rates, primarily relating to debt and certain forecasted sales transactions denominated in currencies other than the U.S. dollar, as well as to changes in interest rates as a result of our variable-rate debt. Consequently, we use derivative financial instruments to manage and mitigate such risk. We do not enter into derivative transactions for speculative or trading purposes. The following table summarizes our outstanding derivative instruments, all of which are designated as cash flow hedges, on a gross basis: Notional Amount Fair Value of Derivative Assets (2) Fair Value of Derivative Liabilities (2) June 30, 2018 December 31, 2017 June 30, 2018 December 31, 2017 June 30, 2018 December 31, 2017 Derivative Instrument: Level 2: Foreign exchange forward contracts $ 118.9 $ 241.3 $ 3.4 $ — $ — $ 4.4 Cross-currency swap (1) 1,430.2 1,478.3 — — 159.8 182.9 Interest rate swap 1,308.9 1,315.5 11.0 — — 19.1 Total hedges $ 2,858.0 $ 3,035.1 $ 14.4 $ — $ 159.8 $ 206.4 (1) The notional values of the cross-currency swap have been translated from Euros to U.S. dollars at the foreign currency rates in effect at June 30, 2018 and December 31, 2017 of approximately 1.16 and 1.20 , respectively. (2) In our consolidated balance sheets, all derivative assets are recorded within prepaid expenses and other current assets and all derivative liabilities are recorded within accrued expenses and other current liabilities.

As of June 30, 2018 , we estimate that approximately $20.4 million of net deferred gains related to our cash flow hedges will be recognized in earnings over the next 12 months. No amounts were excluded from our effectiveness testing during any of the periods presented. Risk Management Strategies Foreign Exchange Forward Contracts We enter into foreign exchange forward contracts with financial institutions to hedge certain forecasted sales transactions denominated in foreign currency. We designate these forward contracts as cash flow hedges, which are recognized as either assets or liabilities at fair value. At June 30, 2018 , the total notional amount of such contracts was $118.9 million , all having maturities of six months or less. Cross-Currency Swap Contract In April 2017 , in order to manage variability due to movements in foreign currency rates related to a Euro-denominated intercompany loan, we entered into a five -year cross-currency swap arrangement (the Cross-Currency Swap). The Cross-Currency Swap, which matures on April 3, 2022 , had an amortizing notional amount of €1,243.3 million at inception (approximately $1,325.4 million ). It converts the 3.00% fixed rate Euro-denominated interest and principal receipts on the intercompany loan into fixed U.S. dollar interest and principal receipts at a rate of 5.44% . Pursuant to the contract, the Euro notional value will be exchanged for the U.S. dollar notional value at maturity. The Cross-Currency Swap has been designated as a cash flow hedge. Accordingly, it is recognized as an asset or liability at fair value and the unrealized gains and losses on the contract are included in gain (loss) on swaps and foreign currency hedging, net within AOCI. Gains and losses are reclassified to interest income or expense over the period the hedged loan affects earnings. As such, amounts recorded in other comprehensive income (loss) (OCI) will be recognized in earnings within or against interest expense when the hedged interest payment is accrued each month. In addition, an amount is reclassified from AOCI to other income (expense), net each reporting period, to offset the earnings impact of the hedged instrument. Interest Rate Swap Contract In April 2017 , we entered into a five -year pay-fixed rate, receive-floating rate interest rate swap arrangement (the Interest Rate Swap) to effectively convert a portion of the variable-rate debt to fixed. The Interest Rate Swap, which matures on April 3, 2022 , had an amortizing notional amount of $1,325.4 million at inception and swaps the variable interest rate on our LIBOR-based borrowings for a fixed rate of 5.44% . The objective of the Interest Rate Swap, which is designated as a cash flow hedge and recognized as an asset or liability at fair value, is to manage the variability of cash flows in the interest payments related to the portion of the variable-rate debt designated as being hedged. The unrealized gains and losses on the contract are included in gain (loss) on swaps and foreign currency hedging, net within AOCI. Amounts recorded in OCI will be recognized in earnings within or against interest expense when the hedged interest payment is accrued each month.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Litigation From time-to-time, we are a party to litigation and subject to claims incident to the ordinary course of business, including intellectual property claims, putative class actions, commercial and consumer protection claims, labor and employment claims, breach of contract claims and other asserted and unasserted claims. We investigate claims as they arise and accrue estimates for resolution of legal and other contingencies when losses are probable and estimable. The amounts currently accrued for such matters are not material. While the results of such normal course claims and legal proceedings cannot be predicted with certainty, management does not believe, based on current knowledge and the likely timing of resolution of various matters, any additional reasonably possible potential losses above the amounts accrued for such matters would be material. Regardless of the outcome, legal proceedings may have an adverse effect on us because of defense costs, diversion of management resources and other factors. Indemnifications In the normal course of business, we have made indemnities under which we may be required to make payments in relation to certain transactions, including to our directors and officers to the maximum extent permitted under applicable state laws and indemnifications related to certain lease agreements. In addition, certain advertiser and reseller partner agreements contain indemnification provisions, which are generally consistent with those prevalent in the industry. We have not incurred material obligations under indemnification provisions historically, and do not expect to incur material obligations in the future. Accordingly, we have not recorded any liabilities related to such indemnities as of June 30, 2018 and December 31, 2017 . We include service level commitments to our customers guaranteeing certain levels of uptime reliability and performance for our hosting and premium DNS products. These guarantees permit those customers to receive credits in the event we fail to meet those levels, with exceptions for certain service interruptions including but not limited to periodic maintenance. We have not incurred any material costs as a result of such commitments during any of the periods presented, and have not recorded any liabilities related to such obligations as of June 30, 2018 and December 31, 2017 . Indirect Taxes We are subject to indirect taxation in some, but not all, of the various states and foreign jurisdictions in which we conduct business. Laws and regulations attempting to subject communications and commerce conducted over the Internet to various indirect taxes are becoming more prevalent, both in the U.S. and internationally, and may impose additional burdens on us in the future. Increased regulation could negatively affect our business directly, as well as the businesses of our customers. Taxing authorities may impose indirect taxes on the Internet-related revenue we generate based on regulations currently being applied to similar, but not directly comparable, industries. There are many transactions and calculations where the ultimate indirect tax determination is uncertain. In addition, domestic and international indirect taxation laws are complex and subject to change. We may be audited in the future, which could result in changes to our indirect tax estimates. We continually evaluate those jurisdictions in which nexus exists, and believe we maintain adequate indirect tax accruals. As of June 30, 2018 and December 31, 2017 , our accrual for estimated indirect tax liabilities was $19.8 million and $18.8 million , respectively, reflecting our best estimate of the probable liability based on an analysis of our business activities, revenues subject to indirect taxes and applicable regulations. Although we believe our indirect tax estimates and associated liabilities are reasonable, the final determination of indirect tax audits, litigation or settlements could be materially different than the amounts established for indirect tax contingencies.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We are subject to U.S. federal, state and foreign income taxes with respect to our allocable share of any taxable income or loss of Desert Newco, as well as any stand-alone income or loss we generate. Desert Newco is treated as a partnership for U.S. income tax purposes and for most applicable state and local income tax purposes and generally does not pay income taxes in most jurisdictions. Instead, Desert Newco's taxable income or loss is passed through to its members, including us. Despite its partnership treatment, Desert Newco is liable for income taxes in certain foreign jurisdictions in which it operates, in those states not recognizing its pass-through status and for certain of its subsidiaries not taxed as pass-through entities. We have acquired the outstanding stock of various domestic and foreign entities taxed as corporations, which are now wholly-owned by us or our subsidiaries. Where required or allowed, these subsidiaries also file and pay tax as a consolidated group for U.S. federal and state income tax purposes and internationally, primarily within the United Kingdom and Germany. We anticipate this structure to remain in existence for the foreseeable future. Based primarily on our limited operating history and our historical losses, we believe there is significant uncertainty as to when we will be able to utilize our net operating losses (NOLs), credit carryforwards and other deferred tax assets (DTAs). Therefore, we have recorded a valuation allowance against the DTAs for which we have concluded it is more-likely-than-not they will not be realized. Based on our analysis of tax positions taken on income tax returns filed, we have determined no material liabilities related to uncertain income tax positions were required. Although we believe the amounts reflected in our tax returns substantially comply with applicable U.S. federal, state and foreign tax regulations, the respective taxing authorities may take contrary positions based on their interpretation of the law. A tax position successfully challenged by a taxing authority could result in an adjustment to our provision or benefit for income taxes in the period in which a final determination is made. Tax Cuts and Jobs Act of 2017 On December 22, 2017 , the Tax Cuts and Jobs Act of 2017 (the TCJA) was signed into law making significant changes to the Internal Revenue Code. Changes include, but are not limited to, a U.S. federal corporate tax rate decrease from 35% to 21% effective for tax years beginning after December 31, 2017 , the transition of U.S international taxation from a worldwide tax system to a territorial system and a one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings. We recorded the estimated impact in accordance with our understanding of the TCJA and guidance available as of December 31, 2017 , as shown in the 2017 10-K. On December 22, 2017 , the SEC issued guidance to address the application of 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 TCJA. The completion of our 2017 income tax returns, future guidance and additional information and interpretations with the respect to the TCJA may cause us to adjust the recorded provisional amounts in a future period. We made no such adjustments during the six months ended June 30, 2018 . In January 2018, the FASB released guidance on the accounting for the global intangible low-taxed income (GILTI) provisions of the TCJA. The GILTI provisions impose a tax on foreign income in excess of a deemed return on tangible assets of foreign corporations. The guidance allows an accounting policy election either to account for deferred taxes related to GILTI inclusions or to treat any taxes on GILTI inclusions as period costs. We have not yet made a policy election with respect to GILTI and have determined its impact to be immaterial.

Related Party Transactions [Abstract]
Payable to Related Parties Pursuant to the TRAs	Payable to Related Parties Pursuant to the TRAs As of December 31, 2017 , our liability under the TRAs was $153.0 million , representing approximately 85% of the calculated tax savings based on the portion of the original basis adjustments we anticipated being able to utilize in future years. During the six months ended June 30, 2018 , we increased this liability primarily through an aggregate $26.1 million reduction in additional paid-in capital resulting from the exchanges of LLC Units in the secondary offerings discussed in Note 4 . As of June 30, 2018 , our liability under the TRAs was $179.2 million . The projection of future taxable income involves significant judgment. Actual taxable income may differ from our estimates, which could significantly impact the liability under the TRAs. We have determined it is more-likely-than-not we will be unable to utilize all of our DTAs subject to the TRAs; therefore, we have not recorded a liability under the TRAs related to the tax savings we may realize from the utilization of NOL carryforwards and the amortization related to basis adjustments created by exchanges of LLC Units. If utilization of these DTAs becomes more-likely-than-not in the future, at such time, we will record liabilities under the TRAs of up to an additional $942.1 million as a result of basis adjustments under the Internal Revenue Code and up to an additional $328.4 million related to the utilization of NOL and credit carryforwards, which will be recorded through charges to our statements of operations. However, if the tax attributes are not utilized in future years, it is reasonably possible no amounts would be paid under the TRAs. In this scenario, the reduction of the liability under the TRAs would result in a benefit to our statements of operations.

Earnings Per Share [Abstract]
Income (Loss) Per Share	Income (Loss) Per Share Basic income (loss) per share is computed by dividing net income (loss) attributable to GoDaddy Inc. by the weighted-average number of shares of Class A common stock outstanding during the period. Diluted income (loss) per share is computed giving effect to all potentially dilutive shares unless their effect is antidilutive. A reconciliation of the numerator and denominator used in the calculation of basic and diluted net income (loss) per share is as follows: Three Months Ended June 30, Six Months Ended June 30, 2018 2017 2018 2017 Numerator: Income from continuing operations $ 20.2 $ 23.4 $ 24.4 $ 20.3 Loss from discontinued operations, net of income taxes — (5.3 ) — (5.3 ) Net income 20.2 18.1 24.4 15.0 Less: net income (loss) attributable to non-controlling interests 2.1 (2.7 ) 3.0 (6.4 ) Net income attributable to GoDaddy Inc. $ 18.1 $ 20.8 $ 21.4 $ 21.4 Denominator: Weighted-average shares of Class A common stock outstanding—basic 152,577 101,800 145,249 95,734 Effect of dilutive securities: Class B common stock 18,662 64,759 24,933 71,579 Stock options 7,409 9,019 7,564 9,384 RSUs and ESPP shares 2,233 1,138 2,209 1,099 Weighted-average shares of Class A Common stock outstanding—diluted 180,881 176,716 179,955 177,796 Net income (loss) attributable to GoDaddy Inc. per share of Class A common stock—basic Continuing operations $ 0.12 $ 0.25 $ 0.15 $ 0.28 Discontinued operations — (0.05 ) — (0.06 ) Net income (loss) attributable to GoDaddy Inc. $ 0.12 $ 0.20 $ 0.15 $ 0.22 Net income (loss) attributable to GoDaddy Inc. per share of Class A common stock—diluted (1) : Continuing operations $ 0.11 $ 0.13 $ 0.14 $ 0.11 Discontinued operations — (0.03 ) — (0.03 ) Net income attributable to GoDaddy Inc. $ 0.11 $ 0.10 $ 0.14 $ 0.08 (1) The diluted income (loss) per share calculations exclude the allocation of net income (loss) to the non-controlling interests. The following number of weighted-average potentially dilutive shares were excluded from the calculation of diluted income (loss) per share because the effect of including such potentially dilutive shares would have been antidilutive: Three Months Ended June 30, Six Months Ended June 30, 2018 2017 2018 2017 Options and RSUs 822 2,755 876 2,792 Shares of Class B common stock do not share in our earnings and are not participating securities. Accordingly, separate presentation of income (loss) per share of Class B common stock under the two-class method has not been presented.

Related Party Transactions [Abstract]
Related Party Transactions	Payable to Related Parties Pursuant to the TRAs As of December 31, 2017 , our liability under the TRAs was $153.0 million , representing approximately 85% of the calculated tax savings based on the portion of the original basis adjustments we anticipated being able to utilize in future years. During the six months ended June 30, 2018 , we increased this liability primarily through an aggregate $26.1 million reduction in additional paid-in capital resulting from the exchanges of LLC Units in the secondary offerings discussed in Note 4 . As of June 30, 2018 , our liability under the TRAs was $179.2 million . The projection of future taxable income involves significant judgment. Actual taxable income may differ from our estimates, which could significantly impact the liability under the TRAs. We have determined it is more-likely-than-not we will be unable to utilize all of our DTAs subject to the TRAs; therefore, we have not recorded a liability under the TRAs related to the tax savings we may realize from the utilization of NOL carryforwards and the amortization related to basis adjustments created by exchanges of LLC Units. If utilization of these DTAs becomes more-likely-than-not in the future, at such time, we will record liabilities under the TRAs of up to an additional $942.1 million as a result of basis adjustments under the Internal Revenue Code and up to an additional $328.4 million related to the utilization of NOL and credit carryforwards, which will be recorded through charges to our statements of operations. However, if the tax attributes are not utilized in future years, it is reasonably possible no amounts would be paid under the TRAs. In this scenario, the reduction of the liability under the TRAs would result in a benefit to our statements of operations. Related Party Transactions As of June 30, 2018 , affiliates of KKR held $10.5 million of the outstanding principal balance of our Term Loans as part of the lending syndicate.

Summary of Significant Accoun26

Summary of Significant Accounting Policies (Policies)	6 Months Ended

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation Our financial statements have been prepared in accordance with generally accepted accounting principles in the United States (GAAP), and include our accounts and the accounts of our subsidiaries. All material intercompany accounts and transactions have been eliminated. Our interim financial statements are unaudited, and in our opinion, include all adjustments of a normal recurring nature necessary for the fair presentation of the periods presented. The results for the interim periods are not necessarily indicative of the results to be expected for any subsequent period or for the year ending December 31, 2018 . These financial statements should be read in conjunction with our audited consolidated financial statements and related notes included in our Annual Report on Form 10-K for the year ended December 31, 2017 (the 2017 Form 10-K).
Prior Period Reclassifications	Prior Period Reclassifications Reclassifications of certain immaterial prior period amounts have been made to conform to the current period presentation.
Use of Estimates	Use of Estimates GAAP requires us to make estimates and assumptions affecting amounts reported in our financial statements. Our more significant estimates include: • the determination of the relative stand-alone selling price of the indicated performance obligations included in revenue arrangements with multiple performance obligations; • the fair value of assets acquired and liabilities assumed in business acquisitions; • the assessment of recoverability of long-lived assets, including property and equipment, goodwill and intangible assets; • the estimated reserve for refunds; • the estimated useful lives of intangible and depreciable assets; • the grant date fair value of equity-based awards; • the fair value of financial instruments; • the recognition, measurement and valuation of current and deferred income taxes; • the recognition and measurement of amounts payable under TRAs or as tax distributions to Desert Newco's owners; and • the recognition and measurement of loss contingencies, indirect tax liabilities and certain accrued liabilities. We periodically evaluate these estimates and adjust prospectively, if necessary. We believe our estimates and assumptions are reasonable; however, actual results may differ from our estimates.
Segment and Reporting Unit	Segment and Reporting Unit As of June 30, 2018 , our chief operating decision maker function was comprised of our Chief Executive Officer who reviews financial information presented on a consolidated basis for purposes of allocating resources and evaluating financial performance for the entire company. Accordingly, we have a single operating segment and reporting unit.
Revenue Recognition	Revenue Recognition Adoption of New Standard on Revenue from Contracts with Customers On January 1, 2018, we adopted the Financial Accounting Standards Board's (FASB) new revenue recognition standard using the modified retrospective method applied to those contracts not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under the new standard, while prior period amounts were not adjusted and continue to be reported in accordance with our historic accounting. The adoption of the new standard did not have a material impact to our financial statements. Revenue Recognition Revenue is recognized when control of the promised services is transferred to our customers, in an amount reflecting the consideration we expect to be entitled to in exchange for those services. We typically receive payment at the time of sale, the purpose of which is to provide our customers with a simplified and predictable way of purchasing our services. We have determined that our contracts do not include a significant financing component. Payments received in advance of our performance are recorded as deferred revenue. Revenue is recognized net of allowances for returns and applicable transaction-based taxes collected from customers. Our products are generally sold with a right of return within our policy, which are accounted for as variable consideration when estimating the amount of revenue to recognize. Refunds are estimated at contract inception using the expected value method based on historical refund experience and updated each reporting period as additional information becomes available and only to the extent it is probable a significant reversal of any incremental revenue will not occur. Refunds result in a reduced amount of revenue recognized over the contract term of the applicable product or service. Our revenue is categorized and disaggregated as reflected in our statements of operations, as follows: Domains . Domains revenue primarily consists of domain registrations and renewals, domain privacy, domain application fees, domain back-orders, aftermarket domain sales and fee surcharges paid to ICANN. Consideration is recorded as deferred revenue when received, which is typically at the time of sale, and revenue, other than for aftermarket domain sales, is recognized over the period in which the performance obligations are satisfied, which is generally over the contract term. Aftermarket domain revenue is recognized when ownership of the domain is transferred to the buyer. Hosting and presence . Hosting and presence revenue primarily consists of website hosting products, website building products and services, website security products, an online shopping cart and online visibility products. Consideration is recorded as deferred revenue when received, which is typically at the time of sale, and revenue is recognized over the period in which the performance obligations are satisfied, which is generally over the contract term. Business applications . Business applications revenue primarily consists of third-party productivity applications, email accounts and email marketing tools. Consideration is recorded as deferred revenue when received, which is typically at the time of sale, and revenue is recognized over the period in which the performance obligations are satisfied, which is generally over the contract term. See Note 6 for additional information regarding our deferred revenue. See Note 14 for our revenue disaggregated by geography. Performance Obligations Our contracts with customers may include multiple performance obligations, including a combination of some or all of the following products or services: domain registrations, website hosting products, website building products and services, website security products and other cloud-based products. Judgment may be required in determining whether products or services are considered distinct performance obligations that should be accounted for separately or as one combined performance obligation. Revenue is recognized over the period in which the performance obligations are satisfied, which is generally over the contract term. For each domain registration or renewal we provide, we have one performance obligation to our customers consisting of two promises: 1) to ensure the exclusive use of the domain during the applicable registration term and 2) to ensure the domain is accessible and appropriately directed to its underlying content. After the contract term expires, unless renewed, the customer can no longer access or use the domain. We have determined these promises are not distinct within the context of our contracts as they are highly interdependent and interrelated and are inputs to a combined benefit. Accordingly, we concluded that each domain registration or renewal represents one service offering and is a single performance obligation. We may also offer specific arrangements, such as GoCentral, in which we include promises to transfer multiple performance obligations in a single service offering. For such arrangements, we allocate the transaction price to each of the underlying distinct performance obligations based on its relative stand-alone selling price (SSP), as described below. We have determined that generally each of our other products and services constitutes an individual service offering to our customers, and therefore have concluded that each is a single performance obligation. For arrangements with multiple performance obligations, we allocate revenue to each distinct performance obligation based on its relative SSP. We use judgment to determine SSP based on prices charged to customers for individual products and services, taking into consideration factors including historical and expected discounting practices, the size, volume and term length of transactions, customer demographics, the geographic areas in which our products and services are sold and our overall go-to-market strategy. Principal versus Agent Considerations We sell our products and services directly to customers and also through a network of resellers. In certain cases, we act as a reseller of products provided by others. The determination of gross or net revenue recognition is reviewed on a product-by-product basis and is dependent on our determination as to whether we act as principal or agent in the transaction. Revenue associated with sales through our network of resellers, for certain aftermarket domain sales and for third-party offerings is recorded on a gross basis as we have determined that we control the product before transferring it to end customers. Assets Recognized from Contract Costs Commissions paid to our resellers represent an incremental cost of obtaining a contract with a customer. We capitalize and amortize such amounts to cost of revenue consistent with the pattern of transfer of the service to which the asset relates. Amounts capitalized and amortized were not material during any of the periods presented. Fees paid to various registries at the inception of a domain registration or renewal represent costs to fulfill a contract. We capitalize and amortize these prepaid domain name registry fees to cost of revenue consistent with the pattern of transfer of the service to which the asset relates. During the three months ended June 30, 2018 and 2017, amortization expense of such asset was $148.7 million and $138.6 million , respectively. During the six months ended June 30, 2018 and 2017, amortization expense of such asset was $294.0 million and $264.4 million , respectively. No other material contract costs were capitalized during any of the periods presented.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In February 2016 , the FASB issued new guidance related to accounting for leases. The new standard requires the recognition of assets and liabilities arising from lease transactions on the balance sheet and the disclosure of key information about leasing arrangements. For leases with a term of 12 months or less, a lessee can make an accounting policy election by class of underlying asset to not recognize an asset and corresponding liability. We will adopt the new standard on January 1, 2019 . Lessees will be required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. While we continue to evaluate the effect of adopting this guidance, we expect the accounting for our operating leases to be the most significant change as a result of the new guidance. We will recognize right-of-use assets and lease liabilities in our consolidated balance sheets upon adoption, which will increase our total assets and liabilities. In June 2016 , the FASB issued new guidance for the accounting for credit losses on instruments that will require entities to measure all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions and reasonable supportable forecasts. This replaces the existing incurred loss model and is applicable to the measurement of credit losses on financial instruments measured at amortized cost and also applies to some off-balance sheet credit exposures. The guidance is effective for annual and interim reporting periods beginning after December 15, 2019 , with early adoption permitted. We are currently evaluating the timing of our adoption and the expected impact of this new guidance. In November 2016 , the FASB issued new guidance requiring amounts generally described as restricted cash and restricted cash equivalents to be included with cash and cash equivalents when reconciling the amounts shown on the statement of cash flows. Our adoption of this new guidance on January 1, 2018 did not have a material impact. In January 2017 , the FASB issued new guidance simplifying the goodwill impairment test, eliminating the requirement for an entity to determine the fair value of its assets and liabilities (including unrecognized assets and liabilities) at the impairment testing date following the procedure that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Instead, an entity will be required to perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity will be required to recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to the reporting unit. The guidance is effective for annual and interim reporting periods beginning after December 15, 2019 , with early adoption permitted. We are currently evaluating the timing of our adoption and the expected impact of this new guidance. In May 2017 , the FASB issued new guidance to amend the scope of modification accounting for share-based payment arrangements. The amendment provides guidance on the types of changes to the terms or conditions of share-based payment awards which would require an entity to apply modification accounting. Our adoption of this new guidance on January 1, 2018 did not have a material impact.
