I just saw a site (http://www.rustybrick.com/pagerank-prediction.php) which tells about the future PR. I have a site with pr3 and tested it. See what result i got Google PageRank Prediction This tool attempts to determine a future Google PageRank value of a particular site. In other words, we try to determine the PageRank value of the URL you enter below, as it would be after the next Google PageRank update. The tools does several calculations to come to this figure. We estimate the value of the future PageRank and then round up or down as Google would. This is an estimation and should not be considered factual, please use with the intention of entertainment purposes only. This site is not affiliated with Google. Enter the URL below and click submit to find out your future Google PageRank. Note: The URL must match the URL you want to check the PR exactly. So please include the "www" if that is what you want to check. Results: Your current Google PageRank is 3. Based on our calculations, we predict your future PageRank after the next Google update will be 10.
yes its really useful atleast it made me smile and came to know predicted pr10 for my site which has hardly 30 unique visitors per day.
I have never seen it predicting a site will have its PR decrease... It seems to the PR always increases
Just for "giggles and grins" I ran the page url this tool is on, through the PR prediction tool ... seems humble, if not honest and potentially accurate:
LOL, the same for one of my sites xD Results: Your current Google PageRank is 4. Based on our calculations, we predict your future PageRank after the next Google update will be 10.
This site has a pagerank prediction based on some rare google numbers: searchengineengine.com (sorry, can't post a live link yet)
Sorry, but I think the tool is crap. I used it off and on several months ago and it was dead wrong on all URL's I submitted through it. Its fun for entertainment purposes, but dont let it take you beyond that.
