Google how does it search




















However, this page focuses on web pages. Google follows three basic steps to generate results from web pages:. The first step is finding out what pages exist on the web. There isn't a central registry of all web pages, so Google must constantly search for new pages and add them to its list of known pages. Some pages are known because Google has already visited them before.

Other pages are discovered when Google follows a link from a known page to a new page. Still other pages are discovered when a website owner submits a list of pages a sitemap for Google to crawl.

If you're using a managed web host, such as Wix or Blogger, they might tell Google to crawl any updated or new pages that you make. Once Google discovers a page URL, it visits, or crawls , the page to find out what's on it. Google renders the page and analyzes both the text and non-text content and overall visual layout to decide where it can appear in Search results. The better that Google can understand your site, the better we can match it to people who are looking for your content.

After a page is discovered, Google tries to understand what the page is about. This process is called indexing. Google analyzes the content of the page, catalogs images and video files embedded on the page, and otherwise tries to understand the page. This information is stored in the Google index , a huge database stored in many computers. The best way to make sure your Web page is high on Google's search results is to provide great content so that other sites will link to your page. The more links your page gets, the higher its PageRank score will be.

If you attract the attention of sites with a high PageRank score, your score will grow faster. A search engine spider does the search engine's grunt work: It scans Web pages and creates indexes of keywords. Once a spider has visited, scanned, categorized and indexed a page, it follows links from that page to other sites. The spider will continue to crawl from one site to the next, which means the search engine's index becomes more comprehensive and robust.

The frequency and location of keywords within the Web page: If the keyword appears only once within the body of a page, it will receive a low score for that keyword. How long the Web page has existed: People create new Web pages every day, and not all of them stick around for long. Google places more value on pages with an established history. The number of other Web pages that link to the page in question: Google looks at how many Web pages link to a particular site to determine its relevance.
