The last PR update or Page Rank update happened about two weeks ago. Only a very small percentage of all the sites looking for this PR update actually had their site’s updated where as the Majority of the websites remained the same. A 100% of all my sites remained the same and I have over a dozen.
People are thinking, and I am also thinking that the past PR update was a Selective PR Update. Google only updated certain sites by picking them out or selecting them out some how, hopefully it was random and not just sites that they feel is good. But the next PR update isn’t supposed to happen for a few months and then we’ll see if Google touches all that we need.
