I have a site about month old that I built about 200 backlinks from do follow PR 0-4 blog comments. I have about 1-2 comments from PR4 blogs, about 10 or more from PR3 blogs, lot's from PR 2 and 1 and 0 also. How is it possible that my pagerank is 4 now? Is there some bug atm? I check it with chrome extension, firrefox extension, with checkpagerank net and they all say the PR is 4. My page is not even RANKING. If it ranked it was between places 50-70. The competition was ridiculously low but the page is not ranking and now my PR is 4? How is it possible..
