PageRank
PageRank is an algorithm used by Google Search to rank web pages in their search engine results.
Description
PageRank was developed by Larry Page and Sergey Brin at Stanford University and is one of the algorithms behind Google's search engine. It works by counting the number and quality of links to a page to determine a rough estimate of the website's importance. The underlying assumption is that more important websites are likely to receive more links from other websites. While the original PageRank algorithm has undergone many changes and improvements, the fundamental idea of using links as a metric for importance and relevance remains central to Google's ranking system. PageRank is not the only factor used by Google to rank pages, but it is one of the more well-known components of their ranking algorithm.
Examples
- A blog post on 'The New York Times' might have a high PageRank because it is linked to by numerous reputable websites such as 'The Guardian', 'BBC', and 'CNN'.
- A product page on 'Amazon' for a popular item like the latest iPhone could also have a high PageRank due to the large number of backlinks from tech review sites, news articles, and social media shares.
Additional Information
- PageRank is only one of over 200 factors that Google uses to rank pages.
- The exact details of the PageRank algorithm are proprietary and have evolved significantly since its inception.
