Finally Google has release Google tool bar page rank but i have notice that this page rank is effected by Panda 2.2 update . and many site has gone it own good page rank and some website gain very little improvement so it is right that June page rank update is effected by Pand update 2.2
Strange things going on with this update with many sites seeing steep rise in PR unlike what it used to be.... I guess the update is not stable.....
How can you be so sure? You can't be sure unless you know the inner workings of Google. Of course they can tweak PR any way they please and if they choose to incorporate penalties it wouldn't be the first time. fark.com are now PR8 but they were stuck at PR4 for the longest time to the puzzlement of SEO's worldwide and the only conclusion anyone could draw was that it was affected by a penalty. I wouldn't be surprised if 2.2 accelerates PR degradation.
mine from pr3 to pr2 in one of my sites but everything is looks normal to my other sites! Unfortunatly not so much defferent on Google search engine!
Google assigns PR to the site after adjudging the quality of their backlinks.... Panda had nothing to do with PR update. It is just concerned with duplicate and poor quality content and SERP rankings.
Actually, it does. From a June 30 post on the Official Google Webmaster Central Blog. Emphasis mine. On top of these assumptions, remember that we only update the PageRank displayed on the Google Toolbar a few times a year, and we may lower the PageRank displayed for some sites if we believe they’re engaging in spammy practices.
