Google Pagerank Status - carefully explained and what you can do with it - written by top SEO experts
Google’s PageRank is an influential algorithm that uses a model of Web use that is dominated by its link structure in order to rank pages by their estimated value to the Web community. This paper reports on the outcome of applying the algorithm to the Web sites of three national university systems in order to test whether it is capable of identifying the most important Web pages. The results are also compared with simple inlink counts. It was discovered that the highest inlinked pages do not always have the highest PageRank, indicating that the two metrics are genuinely different, even for the top pages.
More significantly, however, internal links dominated external links for the high ranks in either method and superficial reasons accounted for high scores in both cases. It is concluded that PageRank is not useful for identifying the top pages in a site and that it must be combined with a powerful text matching techniques in order to get the quality of information retrieval results provided by Google.
Don’t get so involved in Google visible PR.
They are not showing too much consistancy on it. Some sites with 400 relevant (incoming only) links will have a PR5, whereas a site with 40 reciprocated links will have a PR6. My theory is that the “viisible” PR, or the PR that the public sees has no relevance at all. When you look at it from a Google Business model perspective, what does the Google PR toolbar do unless you are trying to optimize your site? It certainly does not help Searchers, which is what Google is geared to, in their quest for information.
