Hi! I have a blog with PR changes this week. I was notified by a PR-based ad sistem that told me that I now earn more because of that. It was originally PR 2, yesterday it was PR 5 and today again its PR 2. Why? Some page rank webs detected PR 5, and some PR 2... I know it is not very important but I have curiosity about this matter. Anybody had something like this? Thanks!
