Most of my sites turned PR0

I have same problem,PR changing . My site was PR3 ,after week PR2.

 

I agree with this point. The incoming links may be not ranked or spam or not original. These are the reasons for drawn to PR0.

 

Ya as someone said in first reply it happens in 3 months

 

Yeh, a lot of site's PR went down after this update. My favorite forum PromoJunkie's pr drops from 6 to 5. And my friend Raihan's forum's PR turns into 0 from 1.

 

PR on my domain is still in place, but I have deindex domain

 

What were they before they were PR0? Just keep on working on them adding content at least every week. It will come back up. You just need to make sure all the links are okay, maybe get a free review here and see what other webmasters think.

 

It's the PR update man.

Hold tight and prepare for a new storm coming.
