As far as I can tell there is only one site that can still predict accurately your future page rank from Google. Their used to be iwebtool but that has stopped working and Page Rank Prediction is the only one standing.
The site itself is very simple, its just a box in which users can input their urls and then the predictor accurately predicts what your new page rank is going to be at the next update.
Page Rank Prediction is predicting that Crenk will be a page rank 5 at the next update, which is great news for us if it is true. Only time will tell and we are expecting to see a new page rank update in the next few days.
Not too long ago the guys over at Killerstartups launched a new service called Dataopedia. Dataopedia is a basic solution that allows users to type in any url and find quickly key metrics from various sources.
Metrics that are measured include Google PR, Alexa Numbers, Compete and Quantcast analysis, Social media breakdowns, Twitter news, Technorati links, Friendfeed and url registration information. Currently, Dataopedia pulls in all this information from various partners including Crunchbase, Compete, Digg, Getsatisfaction and more.
There’s also something interesting buried at the bottom of the site profiles: an ability to comment on the site using Disqus. While that’s not likely to have the reach of a Google Search Wiki, it provides yet another way to gather details about the site and its reputation.
Dataopedia does a great job of pulling all the key quantitative and qualitative site measures required in todays world of web 2.0. There is still a lot of improvements that can be made with the user interface, but over it is probably already leading in this specific market, even thought market is very small.
