When you type a query into a search engine's search bar, it crawls through all of the web pages it has indexed to find the pages that best match your query.<\/p>\n\n\n\n<p>There are several key steps in how a search engine works:<\/p>\n\n\n\n<ul class=\"wp-block-list\" type=\"1\">\n<li><strong>The exploration of web pages:<\/strong> Web crawlers, also known as \"spiders\" or \"crawlers\", continually crawl the web to find new pages and to update existing pages. The robots follow the links from one page to another and add the pages they discover to their index.<\/li>\n\n\n\n<li><strong>Indexing web pages:<\/strong> The content of each crawled page is then analyzed to extract key information, such as keywords and images. This information is then added to a giant index, which is used to route users to the pages most relevant to their search query.<\/li>\n<\/ul>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>Google is a text obsessive <\/p>\n<\/blockquote>\n\n\n\n<ul class=\"wp-block-list\" type=\"1\">\n<li><strong>Ranking of web pages: <\/strong>Search engines use a ranking system to determine the order in which search results should be displayed.
