With the new update some of the sites that got barelly links and have been barely promoted got PR2 and 1 and one of my main sites that I was building hundreds of links daily just got PR1? I also have bought some sites with PR4 that has about 2 links showing in yahoo explorer and it got dropped to PR3 but still has some PR. I totally don't understand how google evaluates the site and gives the PR. Any reliable info would be appriated. THanks..
