    The three key processes in delivering search results to youare:Crawling: Does Google know about your site? Can we find it?Indexing: Can Google index your site?Serving: Does the site have good and useful content that is relevant to the user's search?CrawlingCrawling is the process by which Googlebot discovers new and updated pages to be added to the Google index.We use a huge set of computers to fetch (or "crawl") billions of pages on the web. The program that does the fetching is called Googlebot (also known as a robot, bot, or spider). Googlebot uses an algorithmic process: computer programs determine which sites to crawl, how often, and how many pages to fetch from each site.Google's crawl process begins with a list of web page URLs, generated from previous crawl processes, and augmented with Sitemap data provided by webmasters. As Googlebot visits of each these websites it detects links on each page and adds them to its list of pages tocrawl. New sites, changes to existing sites, and dead links are noted and used to update the Google index.IndexingGooglebot processes each of the pages it crawls in order to compile a massive index of all the words it sees and their location on each page. In addition, we process information included in key content tags and attributes, such as Title tags and ALT attributes. Googlebot can process many, but not all, content types. For example, wecannot process the content of most Flash files or dynamic pages.Serving resultsWhen a user enters a query, our machines search the index for matching pages and return the results we believe are the most relevant to the user. Relevancy is determined by over 200 factors, one of which is the PageRank for a given page. PageRank is the measure of the importance of a page based on the incoming links from other pages. In simple terms, each link to a page on your site from another site adds to your site's PageRank.
