If you're aiming at the
PR Algorithm, no there isn't. But, if you're
aiming at achieving a fake
PR, yes that's possible. This is called
cloaking. Tho, it's pretty easy to detect whether a
PR is real or fake.
Most newbie
SEO's, companies, regular webmasters, etc. don't know
it's possible to fake
PR, which is why cloaking could be used for link
sales to earn money and link exchanges to achieve quality backlinks.
But, of course, a lot of webmasters know about this trick and won't
fall for this.
Cloaking is pretty easy, you're able to get any
PR
for your website, from 0 to 10 wihout doing
SEO.
Google uses a spider to index websites, these
spiders are using known IPs and User-Agents.
Create a .htaccess file or edit your current .htaccess file.
Set your .htaccess file to 301 redirect Google Spiders
to a different website (the website with the
PR you want to copy)
and other visitors to your own website. Now, when Google
spiders your website it's being redirected to a different website.
Google's Spider copies the PageRank of the target website
to your website. Please note that Google strictly disallows this
and they will penalize your website when they find out you're cloaking.
