In 1996, Larry Page and Sergey Brin began developing a search engine at Stanford University. They named the project BackRub because it checked backlinks to determine site importance. The team operated out of Susan Wojcicki's garage in Menlo Park during those early days. By 2004, Google had grown enough to move into its first office space. In August 2009, engineers introduced Caffeine, a new architecture that updated indexes continuously rather than periodically. This change allowed results to be fifty percent fresher by the 8th of June 2010. Danny Sullivan announced the Medic update in August 2018 to improve medical content quality. Hummingbird arrived on the 26th of September 2013, shifting focus from keywords to natural language meaning.
Algorithmic Evolution And Ranking Systems
PageRank remains the core patent behind Google's ranking system today. It computes recursive scores based on weighted sums of incoming links from other pages. Robin Li developed RankDex in 1996, which influenced PageRank before Li created Baidu in 2000. Over years, Google added over two hundred fifty different indicators to refine rankings. Eric Schmidt stated in 2007 that the goal was helping users decide what job to take or what to do tomorrow. In mid-2016, the engine began relying on deep neural networks for processing queries. The Knowledge Graph launched in May 2012 to answer roughly one-third of monthly searches by then. By 2024, AI Overviews replaced older summary methods with generative responses.
