Here is an example that I recently found, most PR checkers will say this domain is PR8 or will say "cannot analyze PR".
The example is domain "bonserotica.com" view Google's cache of the homepage and you'll see as in the picture below, it lists a different URL, which means they used a redirect to a high PR site to fool you and the PR checkers.
Just manage your domain in Enom and choose "Host Records"
Choose "URL Redirect" as the record type.
As shown below choose the URL and add "?redir_mode=301" to the end of it.
To test the 301 and make sure it is a 301 (unlike Godaddy which really did a 302 when I chose 301!).
