What Dominique is saying is true Google’s page rank has nothing to do with where you site will rank on Google.
Basically Page Rank has nothing to do with the relevance of your pages to specific keywords or searches. But it should be noted Page Rank is one of the criteria big businesses look for. Lots of interesting offers can be given for a high PR.
Although my own concern is with serps because this is what brings traffic. But I speculate PR gives your site credibility. greek39
