I came accross a website selling high PR domains of PR4, PR3, PR2 etc. I decided to check the age of some of the domains and it turned out most of them have been registered about 20 days ago, owned by one person, have either just few backlinks from bookmarking sites or don't have backlinks at all... In the first place I thought the PR is fake, so I checked google with a dork Code: info:domain.com to see if result will be the same domain and they all passed this check. After that I checked the domains with a fake PR checker tool... again the fake PR checker tool gave the PR is Valid... Finally when I checked google dork Code: cache:domain.com ...to see what content each domain has had (currently they are parked), all they have had just a plain html, a paragraph of about 200/300 words and a title... I'm sure the owner of these domains knows a solid technique to achieve high PR very quickly... C'mon guys it's been just 20 days and hop... PR4... How is that possible?
