I know that it's not really reliable but why comes the following: I have a site with PR3, which was downsized from PR4 last week. And another site which rose from PR2 to PR4 last week. Since the last google update nothing was changed on these two sites. But now pagerank prediction predicts PR5 and PR6 for those two sites. Sorry if it was recently discussed but I wanted to know how these services operate... why do they predict such high ranks? What are their sources?
Im not sure which tool you are using but the one I know of predicts PR by looking at the site's PR at different data centers (there are more then twenty). When G is doing an update some datacenters will update before the others so the tool checks to see if any are different as an indication of future PR. Aside from that I don't think anyone could guess accurately.
I remember using some pr tool prediction before and it said that Google will be giving me a pr 4 but google just give me a pr 2. they aren't accurate.
never relay on any prediction tools, if they would be accurate then there won't be need of Google Toolbar and we would have just given time in maintaining site and concentrate in SEO.
Like the previous posters said PR prediction doesn't work. Noone has access to Google algorithms. The safest bet is not to pay attention on your PR only but to keep eye on how many relevant backlinks you have to your site. So far the most accurate tool for checking backlinks for me has been yahoo's site:domain.name/page.html You have no idea how many sites rank 1st or second in SERP for some phrases that have only 1 or 2 PR but hundreds and thousands of backlinks.
Just keep getting quality do follow back links and it will all click for you, I wouldn't rely on PageRank "predictions". Good luck with your site!
Hello... come on now... PR update is gone and another wont be around for 3-6 months (not that its important) and those tools are a joke with 10% accuracy at best. Go get some traffic to your site and stop worrying about PR laterz malcolm
Basically they use their own algo to determine the amount of backlinks and then calculate the corresponding expected PR. Btw, this will never be accurate.
I don't think these things work to well, i've read a lot of people have gotten wrong predictions althou it predicted my site correctly Jason Don't waste to much time worrying about it, just keep building backlinks.
I didnt know you could get PageRank predictions! I am a slave to pr - rightly or wrongly - we wont get into that now but I can never get my pr higher and it drops for no reason. so its all about backlinks and finger crossing
