On last 6th October PR were Updated. It changed in few sites. I had seen it. On 7th I check a post the writer of the post had asked about PR, because he found his sites down. I just replied yes PR update. But few reply came to me telling me "No PR not update, my pr still unchanged". I am not getting the point. when PR of all the sites will drop down or PR of all the sites will up from PR0 to PR5 then only PR Updation can be countable OR what? Once PR updation was happened after each 3 or 4 months, but now a days it not fixed to 3 or 4 months. you can search it in Google also. Regards Noor Alam
Most of my sites either dropped by 1 PR, or they stayed exactly the same. I didn't see any changes in keyword rankings though.
