Install the google toolbar and in options select page rank. Straight from the horse's mouth
Use a valid pagerank checker and afterwards make sure the page is also cached- those two things will give you the best results in determining fake or real pr.
One simple way is to check to see how many backlinks the site has. If a site has no (or very few) backlinks, then it should not have a high pagerank.
- Another way to check is to use Google's info: operator.
In Google type: info:domainname.com
If the site info that is returned doesn't match the site that you searched for, then it's probably faked. Otherwise, it's most likely fine.
Use google toolbar for page rank, it show orignal page rank
