A thread in Digital point forum reports changes in Backlinks and PageRank. Some webmasters even say that Google Webmaster Tools have altered their PR from 7 to 6. As many wait for an update in Google PageRank, the time could be this weekend.
"In some sites where I link dropped from PR 7 to PR 6! Maybe big Google is in the process of PR update. My blog is showing PR 4 then goes back to PR 1. Hoping that this next update give positive results to my sites!
This is interesting. I paid for links from one of the blog networks here a couple of months ago. Every link from that network has been dropped from Webmaster Tools for my site. All other backlinks still show up, and links from that network still show in a link: query on Yahoo.
I just lost over 600 backlinks, 1500 is now 876 backlinks, I have not done anything to it, my other sites seem ok though, I have seen this happen before, only temporary though."
Discussion continues at Digital point forum.
