However, even now our Backlink Checker often gets lucky to harvest more than 1,000 backlinks. Use it for multiple sites and you'll see.
You're right. MOST of such tools are just for fun. But our Backlink Checker really predicts future Google PR for any web page with 95% accuracy. Note: it only predicts future PR with 95% accuracy when a site has LESS than 1,000 backlinks. If the site has more than 1,000 backlinks, then accuracy is lower. The more links a site has, the less is the accuracy.
We studied Google PR Formula very well and developed an algorithm which is absolutely same to Google PR. Our Backlink Checker already proven its high accuracy on a huge number of checked websites. Our tool already checked hundreds of thousands of sites, and for 95% of them it predicted the PR correctly.
For me, its working 'right'. Great tool.
