Google Page Rank - How is it calculated???

The secret of Google Page Rank (PR) is finally out...
And I feel proud to bring the original version, directly from the horse's mouth (i.e. from Amit Singhal, Google Fellow in charge of the ranking team at Google)!!

Google ranking is a collection of algorithms used to find the most relevant documents for a user query. We do this for hundreds of millions of queries a day, from a collection of billions and billions of pages. These algorithms are run for every query entered into most of Google's search services. While our web search is the most used Google search service and the most widely known, the same ranking algorithms are also used - with some modifications - for other Google search services, including Images, News, YouTube, Maps, Product Search, Book Search, and more.

There are basically 3 main philosophies behind Google PR:
  1. Best locally relevant results served globally.
  2. Keep it simple.
  3. No manual intervention.

No discussion of Google's ranking would be complete without asking the common - but misguided question: "Does Google manually edit its results?" Let me just answer that with our third philosophy: no manual intervention. Isn't that a good news guys??!!!
