Google feature that helps determine the rank of a site in our search results. PageRank relies on the uniquely democratic nature of the web by using its vast link structure as an indicator of an individual page’s value. Important, high-quality sites receive a higher PageRank, which Google remembers each time it conducts a search. Google combines PageRank with sophisticated text-matching techniques to find pages that are both important and relevant to your searches. Webmaster Help Center

When 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. Google 101

How often does Google crawl the web? Google’s spiders regularly crawl the web to rebuild our index. Crawls are based on many factors such as PageRank, links to a page, and crawling constraints such as the number of parameters in a URL. Any number of factors can affect the crawl frequency of individual sites. Webmaster Help Center
