Overview

Google is a global technology leader focused on improving the ways people connect with information. Our innovations in web search and advertising have made our web site a top internet property and our brand one of the most recognized in the world. Our mission is to organize the world's information and make it universally accessible and useful. We serve three primary constituencies:

• Users. We provide users with products and services that enable people to more quickly and easily find, create and organize information that is useful to them.

• Advertisers. We provide advertisers with cost-effective ways to deliver online ads, as well as offline ads on television, to customers across Google sites and through the Google Network, which is the network of online and offline third parties that use our advertising programs to deliver relevant ads with their search results and content.

• Google Network Members and Other Content Providers. We provide the online and offline members of our Google Network with our Google AdSense programs. These include programs through which we distribute our advertisers' AdWords ads for display on the web sites of our Google Network members as well as programs to deliver ads on television broadcasts. We share most of the fees these ads generate with our Google Network members, thereby creating an important revenue stream for them. In addition, we have entered into arrangements with other content providers under which we distribute or license their video and other content, and we may display ads next to or as part of this content on the pages of our web sites and our Google Network members' web sites. We share most of the fees these ads generate with these content providers and our Google Network members, thereby creating an important revenue stream for these partners.

How We Generate Revenues

Advertising revenues made up 97% of our revenues for the three and six months ended June 30, 2008 and 2009. We derive most of our additional revenues from offering internet ad serving and management services to advertisers and ad agencies and the license of our enterprise products, search solutions, and web search technology.

Google AdWords is our automated online program that enables advertisers to place targeted text-based and display ads on our web sites and our Google Network members' web sites. Most of our AdWords customers pay us on a cost-per-click basis, which means that an advertiser pays us only when a user clicks on one of its ads. We also offer AdWords on a cost-per-impression basis that enables advertisers to pay us based on the number of times their ads appear on our web sites and our Google Network members' web sites as specified by the advertiser. For advertisers using our AdWords cost-per-click pricing, we recognize as revenue the fees charged advertisers each time a user clicks on one of the ads that appears next to the search results on our web sites or next to the search results or content on our Google Network members' web sites. For advertisers using our AdWords cost-per-impression pricing, we recognize as revenue the fees charged advertisers each time their ads are displayed on our web sites or the Google Network members' web sites. Our AdWords agreements are generally terminable at any time by our advertisers.

Google AdSense refers to the online programs through which we distribute our advertisers' AdWords ads for display on the web sites of our Google Network members as well as programs to deliver ads on television. Our AdSense programs include AdSense for search and AdSense for content.

AdSense for search is our online service for distributing relevant ads from our advertisers for display with search results on our Google Network members' sites. To use AdSense for search, most of our AdSense for search partners add Google search functionality to their web pages in the form of customizable Google search boxes. When visitors of these web sites search either the web site or the internet using these customizable search boxes, we display relevant ads on the search results pages, targeted to match user search queries. Ads shown through AdSense for search are text ads.

AdSense for content is our online service for distributing ads from our advertisers that are relevant to content on our Google Network members' web sites. Under this program, we use automated technology to analyze the meaning of the content on the web page and serve relevant ads based on the meaning of such content. For example, a web page on an automotive blog that contains an entry about vintage cars might display ads for vintage car parts or vintage car shows. These ads are displayed in spaces that our AdSense for content partners have set aside on their web sites. AdSense for content allows a variety of ad types to be shown, including text ads, image ads, Google Video Ads, link units (which are sets of clickable links to topic pages related to page content), themed units (which are regular text ads with graphic treatments that change seasonally and by geography), and gadget ads (which are customized "mini-sites" that run as ads on AdSense publisher web sites).

For our online AdSense program, our advertisers pay us a fee each time a user clicks on one of our advertisers' ads displayed on our Google Network members' web sites or, for those advertisers who choose our cost-per-impression pricing, as their ads are displayed. To date, we have paid most of these advertiser fees to our Google Network members, and we expect to continue doing so for the foreseeable future. We recognize these advertiser fees as revenue and the portion of the advertiser fee we pay to our Google Network members as traffic acquisition costs under cost of revenues. In some cases, we guarantee our Google Network members minimum revenue share payments based on their achieving defined performance terms, such as number of search queries or advertisements displayed. Google Network members do not pay any fees associated with the use of our AdSense program on their web sites.

Our agreements with Google Network members consist largely of uniform online "click-wrap" agreements that members enter into by interacting with our registration web sites. The standard agreements have no stated term and are terminable at will. Agreements with our larger members are individually negotiated. Both the standard agreements and the negotiated agreements contain provisions requiring us to share with the Google Network member most of the advertiser fees generated by users clicking on ads on the Google Network member's web site or, for advertisers who choose our cost-per-impression pricing, as the ads are displayed on the Google Network member's web site.

Google TV Ads enables advertisers, operators, and programmers to buy, schedule, deliver and measure ads on television. We recognize as revenue the fees charged advertisers each time an ad is displayed on television.

DoubleClick provides us with a platform for delivering display advertising. DoubleClick offers online ad serving and management services to advertisers, ad agencies and web site publishers. Fees derived from hosted or web-based applications are recognized as licensing and other revenues in the period the advertising impressions are delivered.

We have entered into arrangements with certain content providers under which we distribute or license their video and other content. Our agreements with content providers are typically standard agreements with no stated term and are terminable at will. Agreements with our larger members are individually negotiated. Both the standard agreements and the negotiated agreements contain provisions requiring us to pay the content providers for the content we license. In a number of these arrangements, we display ads on the pages of our web sites and our Google Network members' web sites from which the content is viewed and share most of the fees these ads generate with the content providers and Google Network members. We recognize these advertiser fees as revenue. We recognize the portion of the advertiser fees we pay to our content providers as content acquisition costs under cost of revenues and the portion we pay to our Google Network members as traffic acquisition costs. In some cases, we guarantee our content providers minimum revenue share or other payments.

We believe the factors that influence the success of our advertising programs include the following:

• The relevance, objectivity, and quality of our search results and the relevance and quality of ads displayed with each search results page.

• The number of searches initiated at our web sites and our Google Network members' web sites and the underlying purpose of these searches (for instance, whether they are for academic research, to find a news article, or to find a product or service).

• The number and prominence of ads displayed on our web sites and our Google Network members' web sites.

• The advertisers' return on investment from advertising campaigns on our web sites or our Google Network members' web sites compared to other forms of advertising.

• The total advertising spending budgets of each advertiser.

• The number of advertisers and the breadth of items advertised.

• The amount we ultimately pay our Google Network members, distribution partners, and our content providers for traffic, access points, and content compared to the amount of revenue we generate.

Trends in Our Business

Our business has grown rapidly since inception, resulting in substantially increased revenues, and we expect that our business will continue to grow. However, our revenue growth rate has generally declined over time, and we expect it will continue to do so as a result of a number of factors including increasing competition, the difficulty of maintaining growth rates as our revenues increase to higher levels and increasing maturity of the online advertising market in certain countries. In addition, the continuing weak economic conditions have adversely impacted our revenue growth rate and may result in fewer commercial queries by our users and may cause advertisers to reduce the amount they spend on online advertising, including the amount they are willing to pay for each click or impression, which could negatively affect the growth rate of our revenues.

The main focus of our advertising programs is to provide relevant and useful advertising to our users, reflecting our commitment to constantly improve their overall web experience. As a result, we expect to continue to take steps to improve the relevance of the ads displayed on our web sites and our Google Network members' web sites. These steps include not displaying ads that generate low click-through rates or that send users to irrelevant or otherwise low quality sites and terminating our relationships with those Google Network members whose web sites do not meet our quality requirements. We may also continue to take steps to reduce the number of accidental clicks by our users. These steps could negatively affect the growth rate of our revenues.

Both seasonal fluctuations in internet usage and traditional retail seasonality have affected, and are likely to continue to affect, our business. Internet usage generally slows during the summer months, and commercial queries typically increase significantly in the fourth quarter of each year. These seasonal trends have caused, and will likely continue to cause, fluctuations in our quarterly results, including fluctuations in sequential revenues, as well as paid click and average cost-per-click growth rates.

The operating margin we realize on revenues generated from ads placed on our Google Network members' web sites through our AdSense program is significantly lower than the operating margin we realize from revenues generated from ads placed on our web sites because most of the advertiser fees from ads served on Google Network members' web sites are shared with our Google Network members. For the past five years, growth in advertising revenues from our web sites has generally exceeded that from our Google Network members' web sites. This trend has had a positive impact on our operating margins, and we expect that this will continue for the foreseeable future, although the relative rate of growth in revenues from our web sites compared to the rate of growth in revenues from our Google Network members' web sites may vary over time.

We continue to invest in building the necessary employee and systems infrastructures required to manage our growth and develop and promote our products and services, and this may cause our operating margins to decrease. We have generally experienced and expect to continue to experience growth in our operations as we build our research and development programs, expand our base of users, advertisers, Google Network members, and content providers, and increase our presence in international markets. Also, we have acquired and expect to continue to acquire businesses and other assets from time to time. These acquisitions generally enhance the breadth and depth of our expertise in engineering and other functional areas, our technologies and our product offerings. Our full-time employee headcount was 19,604 at June 30, 2008 and 19,786 at June 30, 2009. We have recently made efforts to improve the discipline of our hiring process and to focus on better managing our expense growth. However, we expect to continue to invest in our business, and this may cause our operating margins to decrease.

We expect our cost of revenues to increase in dollars and may increase as a percentage of revenues in future periods, primarily as a result of forecasted increases in traffic acquisition costs, data center costs and credit card and other transaction fees, as well as content acquisition costs. In particular, traffic acquisition costs as a percentage of

advertising revenues may increase in the future if we are unable to continue to improve the monetization or generation of revenues from traffic on our web sites and our Google Network members' web sites, particularly with those members to whom we have guaranteed minimum revenue share payments.

Our international revenues have grown as a percentage of our total revenues from 52% in the three months ended June 30, 2008 to 53% in the three months ended June 30, 2009. This increase in the portion of our revenues derived from international markets results largely from increased acceptance of our advertising programs, and our continued progress in developing localized versions of our products in these international markets. The increase in the proportion of international revenues derived from international markets increases our exposure to fluctuations in foreign currency to U.S. dollar exchange rates. For example, in the second quarter of 2009, the general strengthening of the U.S. dollar relative to foreign currencies (primarily the British pound and the Euro) as compared to the second quarter of 2008 had an unfavorable impact on our revenues. We have a foreign exchange risk management program that is designed to reduce our exposure to fluctuations in foreign currencies; however, this program will not fully offset the effect of fluctuations on our revenues and earnings.

The growth in our advertising revenues from the three months ended June 30, 2008 to the three months ended June 30, 2009, and from the six months ended June 30, 2008 to the six months ended June 30, 2009 resulted from an increase in the number of paid clicks generated through our advertising programs as well as hedging gains recognized from our foreign currency risk management program, partially offset by a decrease in the average cost-per-click paid by our advertisers. The increase in the number of paid clicks generated through our advertising programs was due to an increase in aggregate traffic, certain monetization improvements, and the continued global expansion of our products, our advertiser base, and our user base. The decrease in the average cost-per-click paid by our advertisers was primarily the result of the general strengthening of the U.S. dollar relative to foreign currencies (primarily the British pound and the Euro), as well as changes in geographical mix due to traffic growth in emerging markets compared to more mature markets. In addition, the decrease in the average cost-per-click was due to how we believe advertisers managed their advertising costs in response to continuing weak economic conditions. Specifically, we believe that as a result of the general economic downturn, advertisers, in aggregate, have lowered their bids for keywords in response to a decrease in the sales they are able to make per paid click.

From the three months ended June 30, 2008 to the three months ended June 30, 2009, advertising revenue growth for Google web sites and Google Network members' sites resulted primarily from an increase in aggregate traffic, certain monetization improvements, and the continued global expansion of our products, our advertiser base and our user base. From the six months ended June 30, 2008 to the six months ended June 30, 2009, advertising revenue growth for Google web sites resulted primarily from an increase in aggregate traffic, certain monetization improvements, and the continued global expansion of our products, our advertiser base and our user base. From the six months ended June 30, 2008 to the six months ended June 30, 2009, revenues generated from Google Network members' sites were relatively unchanged.

Improvements in our ability to ultimately monetize increased traffic primarily relate to enhancing the end user experience, including providing end users with ads that are more relevant to their search queries or to the content on the Google Network members' web sites they visit. These improvements have included, for instance, continued enhancements to the web search results page, a reduction in minimum cost-per-click to show more good quality ads, a change to the formula used to determine which ads appear at the top of our search results pages, and a change to the clickable area around our AdSense for content text-based ads to only the title and URL to reduce the number of accidental clicks. In addition, these improvements have included certain changes to further enhance the accuracy of our quality scoring, which is our measurement of an ad's click-through rate and other relevancy factors.

Aggregate paid clicks on Google web sites and our Google Network members' web sites increased 15% from the three months ended June 30, 2008 to the three months ended June 30, 2009 and 16% from the six months ended June 30, 2008 to the six months ended June 30, 2009 and decreased 2% from the three months ended March 31, 2009 to the three months ended June 30, 2009. Average cost-per-click on Google web sites and our Google Network members' web sites decreased 13% from the three and six months ended June 30, 2008 to the three and six months ended June 30, 2009 and increased 5% from the three months ended March 31, 2009 to the three months ended June 30, 2009. The rate of change in aggregate paid clicks and average cost-per-click, and their correlation with the rate of change in revenues, has fluctuated or may in the future fluctuate because of various factors including the revenue growth rates on our web sites compared to those of our Google Network members, advertiser competition for keywords, changes in foreign currency exchange rates, seasonality, the fees advertisers are willing to pay based on how they manage their advertising costs, and the recent economic downturn. In addition, traffic growth in emerging markets compared to more

mature markets and across various advertising verticals also contributes to these fluctuations. Changes in aggregate paid clicks and average cost-per-click may not be indicative of our performance or advertiser experiences in any specific geographic market, vertical, or industry.
