It is actually possible to fake PageRank by setting up redirection.
Just a quick search amongst the domain name sellers in Australia actually found people doing this.
To check whether a domain is truly reflecting it’s own PageRank, simply Google:
info:exampledomainname.com
If the result shows another domain not as per the one you typed in search, you know there is redirection set up and the searched domain’s PageRank is actually the one you see being ‘reflected’ by the redirect. You would be a fool to be buying a domain thinking it has a high page rank when it has zero
A quick search in Google:
link:exampledomainname.com
Will also reveal some back-links Google recognise to the searched domain name. The more authoritative the back links to the domain, the more valuable the domain.
