2 week old website with PR4?

This is the other way to fake PR, but you risk ruining your site if you use this method. Google doesn't like cloaks too much. You risk getting penalized or worse for this, and while doing it your site has no hope of ranking. Google sees it as if it is a 301 redirect, and everything passes through.

If you want to check a few things to determine if a site is faking PR, you know how to do that now. If you want to check to see if the site is permanently redirecting SE bots using a cloak and php redirect, then you can check two different scenarios...

First, do a regular search in Google for the domain in question (after checking it with the info: operator). You'll notice that the same site comes up that you searched for with the "info:" operator, and additionally, you will see the domain that you actually searched for listed afterwards. This indicates that the redirect isn't in place.

Next, check the backlinks separately of each of those sites. The reason for this is that if a redirect is in place, it should forward all backlinks to the redirect site as well. If the site you are searching for has backlinks separate of the target site, then it is most likely not redirected. In this case, getmentocommit.com has a backlink of its own.

To check if a php redirect is currently in place, you can also check the cached pages in Google after doing a search for the domain name. It will show the cache of site it is redirected to in this case. However, you'll notice that these sites are cached of their own content.

I had checked both early on when I was checking to see if the PR was faked. This is how I deduced that is was faked, and that there is no redirect in place any longer - 301 or cloaked.
