3 of my sites still the same ranking. Doesn't have any different from previous . Seem if it really have minor changes, it might be the new update is coming . It seem fast while Google Panda and Penguin just updated .
No dear I nothing got any PR update for my websites. My Website PR is 3 and just now also at 3 PR position in Google. So i think not pr update.
Bro PR is still an important factor in deciding your Google search engine rankings. You will get your site page instantly indexed if you have pr of 1 and 2.
btw, because of recent penguin update my site dropped from PR 2 to 1. Hope can make it move higher again this time.
