Google's Approach to Searching the Internet
Google Search Services
About Google Inc.
The Meaning of Google
Google's mission is to organize the world's information, making it universally accessible and useful.
Google focuses exclusively on delivering the best search experience on the World Wide Web. Through innovative advances in search technology, Google helps its users find the information they're looking for with unprecedented levels of ease, accuracy, and relevancy. The company delivers its services to individuals and enterprises through its own public destination site, www.google.com, and through co-branding its WebSearch and SiteSearch services.
Google was founded in 1998 by Larry Page and Sergey Brin, two Stanford Ph.D. candidates, who developed a technologically advanced methodology for finding information on the Internet. Based on years of research into large-scale data mining in general, and into analysis of the link structure of the World Wide Web in particular, Larry and Sergey determined that by using a complex mathematical analysis they could estimate the quality or importance -- and thus the relevancy -- of the web pages returned by a search.
Their combined research efforts resulted in the creation of a sophisticated, next-generation search engine that uses complex mathematical algorithms to determine importance and relevancy of web pages. This fully automated and scalable approach to search enables Google to get better as the Internet gets bigger. The benefit to Google users is the accurate and fast return of high-quality, highly relevant search results.
The Internet's growth as a massive, dynamic repository of the world's information continues at an unprecedented rate. Forrester Research estimates that 1.5 million pages are added to the Internet each day. According to a recent NEC Research Institute report, the publicly indexable web contains about 800 million pages, encompassing about 6 terabytes of text data, on about 3 million servers.
Because Internet users must rely on search technology to help find and sort through vast amounts of information, search engines have been widely recognized as critical components to Internet use. The Graphic, Visualization, and Usability Center estimates that about 85 percent of Internet users access search engines to find information, and according to MediaMetrix, today's popular search engines are consistently ranked among the top 10 sites accessed on the web. These first-generation search engines have become universal features on portals and commercial websites, as users strive to find information on the ever-expanding, increasingly unorganized Internet.
Google's innovative search technology and elegant user interface design set Google apart from today's first-generation search engines. Rather than using only keyword or metasearch technology, Google is based on advanced patent-pending technology, which ensures that the most important results always come up first. Google's distinctive approach to searching the Internet is based on the following features:
An Elegant, Easy-to-Use Interface: Google's clean,
uncluttered interface is designed to make it easy for users to
enter search queries and interpret results. Results are
presented with context sensitive summaries so users can easily
tell if the corresponding web pages will satisfy their need.
Users can also enter a query and click the "I'm Feeling
LuckyTM" button, which takes users directly to the
website of the first search result. For example, entering
smithsonian into Google search field and clicking
the "I'm Feeling Lucky" button takes the user directly to
www.si.edu, the official homepage of the Smithsonian
Sophisticated Text-Matching: Unlike conventional search engines, Google is hypertext-based. It analyzes all the content on each web page and factors in fonts, subdivisions, and the precise positions of all terms on the page. Google also factors in the content of neighboring web pages. All of this data enables Google to return results that are more relevant to user queries.
Patent-Pending PageRankTM Technology: Core to Google's search engine is its patent-pending PageRank technology. PageRank performs an objective measurement of the importance of web pages and is calculated by solving an equation of 500 million variables and more than 2 billion terms. PageRank uses the vast link structure of the web as an organizational tool. In essence, Google interprets a link from Page A to Page B as a "vote" by Page A for Page B. Google assesses a page's importance by the votes it receives. Google also analyzes the page that casts the vote. Votes cast by pages that are themselves "important" weigh more heavily and help to make other pages "important." Important, high-quality pages receive a higher PageRank and are ordered higher in the results. Google's technology uses the collective intelligence of the web to determine a page's importance. Google does not use editors or its own employees to judge a page's importance.
Results are delivered in order of importance and relevance: Google helps users get to the results they're looking for by delivering the most relevant and important results first, and by providing an excerpt from the web page with search terms highlighted in boldface type.
Integrity in Search Results: Google delivers only true search results, based on the objective, automated PageRank and text-matching measures. Our technology prevents manipulation of returned results by spammers and marketers, and we never alter the rank of our results based on advertising.
Google offers its advanced search technology to individual users through the company's search destination site, www.google.com. Google also offers the same high-quality search capabilities to portals and commercial websites with its Google SiteSearch and Google WebSearch services.
Google SiteSearch is designed to search for information contained within a specific website. For example, RedHat, Inc., a leading developer and provider of open source Linux-based operating system, uses Google's SiteSearch capability to enable visitors to its site to search for information contained only within the RedHat.com website.
Google WebSearch offers web-wide search capabilities to commercial websites. Netscape's Netcenter portal uses Google's WebSearch capability to enable its visitors to search the entire web from the Netcenter portal.
Google offers special searches for users who want to find information pertaining to a special topic. For example, users who want to search the web for information on the popular Linux operating system can use the special Linux Search feature located on the Google search destination site. Similarly, Google offers special search engines for users looking for information on the U.S. Government and on Stanford University. These special search engines help to narrow a query by searching only a subset of the web, providing pages that are even more likely to be relevant to a users needs.
Google provides its search technologies commercially to customers through its Google WebSearch and Google SiteSearch services. Google's commercial products are hosted by Google, alleviating the need for organizations to manage their own costly search software and resources. Google SiteSearch is designed to search for information contained within a specific website. For example, RedHat, Inc. uses the Google SiteSearch capability to enable its visitors to search for information contained only on its RedHat.com website. Google WebSearch offers web-wide search capabilities to commercial websites. Netscape's Netcenter portal uses the Google WebSearch service to enable its visitors to search the entire web from the Netcenter portal.
With more than 3.5 million searches per day, Google also offers advertisers a highly trafficked web location to attract customers. Unlike current generation search engines, Google's advertising is precisely targeted and graphically designed to enhance a user's overall search experience. Google's distinctive approach to advertising offers the same elegant, clean interface that characterizes the Google search experience.
Google is based in Mountain View, Calif. The company currently offers search solutions through its own destination site at www.google.com. The company also offers co-branded web search and site search solutions for information content providers.
Google is privately held. The company's funding partners include Kleiner Perkins Caufield & Byers and Sequoia Capital. The company announced in June 1999 that Michael Moritz, general partner of Sequoia Capital, and John Doerr, general partner of Kleiner Perkins Caufield & Byers, joined Google's Board of Directors. Moritz is currently director of numerous companies, including Yahoo, eToys, Quote.com, eGroups, PlanetRx, Flextronics, and WebVan. Doerr was a co-founder of @Home, and is a director of several high-growth Internet companies, including Amazon.com, DrugStore.com, Handspring, Healtheon/WebMD, Homeshop.com, Intuit, and Sun Microsystems.
Other investors include Stanford University; Andy Bechtolsheim, co-founder of Sun Microsystems and current vice president at Cisco Systems; and Ram Shriram, who has held the positions of president of Junglee and vice president of Business Development at Amazon.com.
Google is a play on the word googol, which was coined by Milton Sirotta, nephew of American mathematician Edward Kasner, to refer to the number represented by 1 followed by 100 zeros. Google's use of the term reflects the company's mission to organize the immense amount of information available on the web and in the world.
