PR

PR is the abbreviation of Page Rank. Page Rank is the system for ranking web pages. A page with a higher Page Rank is deemed more important and is more likely to be listed above a page with a lower Page Rank. Page Rank relies on the uniquely democratic nature of the web by using its vast link structure as an indicator of an individual page’s value.

Page Rank is a numeric value that represents how important a page is on the web. When one page links to another page, it is effectively casting a vote for the other page. The more votes that are cast for a page, the more important the page must be.

Page Rank is the way to determine a page's importance. It matters because it is one of the factors that determine a page's ranking in the search results.
