They usually update from time to time I guess. Even if it's not the PR, sometimes, the inbound links are being updated. I noticed that on the sites that I am handling before. It's normal, and a good thing if your IBLs increase. :P
that's why google is the best, they update their databases from time to time most of the websites increased backlink but there are cases that website decreasing its backlinks.
what are some good suggestions to up my pr on google right now i am paying about $10,000 a month for google adwords
