There has finally been a Google PR update. It’s been almost a year since the last one, so it’s about time.
From what I see, it’s only a public update for the PR, but I suspect that PR is changing on a daily basis. This means that if your sites dropped in PR, that drop in PR was likely internalized in Google for a long time already, it’s just being made public now.
I don’t think it’s anything to worry about, but just keeping you updated on the latest SEO happenings.
Oh! i went from pr0 – pr2, have you seen any changes for your sites?
