Developed by Google’s founders Larry Page & Sergey Brin at Stanford University, PageRank is essentially Google’s way of ranking a web page. Developed on a logarithmic scale from 0-10 SEO’s used to be able to use Google’s PageRank toolbar to understand the “rank” of a given page which used to be particularly valuable when trying to identify high “authority” pages or pages where they wanted to gain a link.
Fast forward to today & PageRank is no longer a visible metric making it harder for SEO’s to use it effectively. As a result, many have turned to other tools such as AHREF’s Domain Rank or Majestic’s TrustFlow to understand how Google may view their website – both offering valuable insight in to the performance of any given website, allowing SEO’s to draw effective competitor analysis & identify key gaps or areas within the market on specific keyword targets.
