PageRank is a technology that calculates page ranking in a search engine based on links between pages. PageRank is a way Google identifies the rank or importance of a web page. Its level from 1 to 10, the higher the PR value, indicating that the web is more popular (the more important). PageRank approximates the likelihood that a user will click a link randomly on Internet to reach a particular web page. In general, pages that can be reached from more places are more important, and therefore have higher PageRank.
