Google uses a complex algorithm called PageRank to rank web pages in its search results. PageRank evaluates the quality and quantity of links to a webpage to determine a rough estimate of how important the website is. The underlying assumption is that more important websites are likely to receive more links from other websites. However, it’s important to note that PageRank is just one part of Google’s overall ranking algorithm. Google’s algorithm takes into account hundreds of different factors, including relevancy of the content to the search query, the E-A-T principles, the user experience on the website, mobile-friendliness, page speed, and many others.
