Fake Page rank is becoming a very serious problem. When somebody is offering a domain name for sale, they can synthetically increase the domain’s PageRank. It is achieved when fraud domains use a 301 or 302 redirects which point their websites to sites with a high PR. This is a well-known trick in the SEO world, but people who aren’t familiar with Search Engine Optimization are most likely to fall for this.
A website can have a fake PR when the Page Rank returned from the Google servers is actually the Rank of a other site. A website with fraud PR has mainly tricked Google into believing it’s really another website on the net and then Google assigns both sites a identical PageRank score.
