How is Page Rank created?

I see a lot of tools that can check page rank of links and such...how do they et
incorporate those into their programs?

Is there a formula that you can use to calculate Page Rank? I'm thinking about slapping together a simple tool to do something like this because I'm broke so I can't afford tools just y

they dont calculat anything, its like alexa rank check it from alexa itself so i think they check the PR from Google too, but i dont know why there is no formal website for the PR from Google!

There is an article on wikipedia. It says somewhere that it was a patent created by Stanford and licenced to google.

But google changed the algorithm and they havent revealed the exact method.

You can gather a sample of ranked pages and check pre-made algorithms to see which works (comes closer to Google PR) better. It will always be an approximation i suppose.

I am not allowed(yet) to post urls so google pagerank wikipedia to find the article.There are some ideas for potential algorithms.

If you succeed I'd love to use it.

Well the closest you can probably get is to use the original PR formula. Google has modified it over the years in an effort to keep webmasters from gaming the system, but the original formula should still be good enough for what your looking for.

Here is the best article I know of to help you with what your looking for
