How Google Search organizes information When you Search, Google looks through hundreds of billions of webpages and other content stored in our Search index to find helpful information — more information than all of the libraries of the world. Three people sorting information on cards Finding information by crawling Most of our Search index is built through the work of software known as crawlers. These automatically visit publicly accessible webpages and follow links on those pages, much like you would if you were browsing content on the web. They go from page to page and store information about what they find on these pages and other publicly-accessible content in Google's Search index.
