a score out of ten assigned by Google to each indexed web page. The visible result of the algorithm, but note that the 'public' PR is not the same as the 'true' PR and is only updated infrequently. PR0 ( PageRank = 0 ), PR1 ( pageRank = 1 ), PR2 ( PagrRank = 2 )... The higher the PR, the more valuable the website.
