What does PR4 mean when it comes to web ranking? This means that Google views the website as a good website. PR means Page Rank and is named after Google co-founder Larry Page. The higher the PR, the higher the web site ranks in the Google search.

Larry Page was interested in exploring the mathematical properties of the World Wide Web and understanding its link structure. He focused on the problem of finding out which web pages link to a given page, considering the number and nature of such backlinks to be valuable information about that page. He developed the PageRank algorithm, and realized that it could be used to build a search engine that is superior to existing ones. In 1996 the initial version of Google was made available. Through this PR algorithm, websites are ranked in the Google.

When linking to a website, it is best to link to one that has a higher PR on the home page.
