hey does anyone know if there is a site like archive.org that lets you see the google pr history of any site? i think this would be quite useful for those looking to purchase sites and/or domains.
SEOmoz has a tool that is free with registration and does this for you. Just type in SEOMoz in Google and it should be the first thing that comes up.
actually after testing it with more than a few domains its not 100% accurate. the pr's from a month ago are pretty much the same as they are today on a few domains where i know the pr just increase last week.
I really don't think anything's going to be 100% accurate. Best thing to do is try different tools and compare the results. Then go with the one that's most effective.
