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.
How does Forged Google Rank work?
PageRank is faked, when a website uses a 301 redirection to redirect their domain to a higher ranked site. 301 redirect is search spider talk for moved permanently. When a search bot reads this, it considers page has moved permanently and that the redirect will stay.
The script, with such redirects, is written on the stealing website that automatically redirects any inward requests from Google's crawler to another site with high PageRank. This efficiently confuses the Google robot into thinking the site's are the same and the stealing site finally inherits the other site's PR.
How can you protect yourself from Fake PR?
There are factually hundreds of websites on the net that will tell you what Page Rank a site has. The difficulty is that only some of them can tell you if that Page Rank is really valid. Our Pagerank Fraud tool can verify if a site has a valid or fake Page Rank.
Is Google detecting fake PR?
Many of the bloggers that paid for blogging just got their PR down to a zero. It could mean that their blogs are no longer passing any factual link value for SEO purposes. One thing we know for sure, the blog that had PR5 or PR6 yesterday that is now a PR0 did not loose all the links value.
Really, these blogs are not really PR0s, Google just injured these blogs to destroy their value in selling links or content on them. Most of these blogs are still getting a lot of traffic from Google, so Google just publishes a fake zero to further their own agenda.
