We dive into what that really means. In the original form of PageRank, the sum of PageRank over all pages was the total number of pages on the web at that time, so each page in this example would have an initial value of 1. Since D had three outbound links, it would transfer one third of its existing value, or approximately 0.083, to A. In a nutshell, it considers links to be like votes. At the completion of this iteration, page A will have a PageRank of approximately 0.458. PageRank (PR) + Java Example.

This means that the more outbound links a page T has, the less will page A benefit from a link to it on page T. The weighted PageRank of pages Ti is then added up. It uses the quality of other websites, and how many links from external sites the site has to calculate the site's rank.
