    According to Sergey Brin and Lawrence (Larry) Page, Co-founders of Google, the PR of a webpage is calculated using this formula:

    PR(A) = (1 - d) + d * SUM ((PR(I->A)/C(I))

    Where:

    PR(A) is the PageRank of your page A.
    d is the damping factor, usually set to 0,85.
    PR(I->A) is the PageRank of page I containing a link to page A.
    C(I) is the number of links off page I.
    PR(I->A)/C(I) is a PR-value page A receives from page I.
    SUM (PR(I->A)/C(I)) is the sum of all PR-values page A receives from pages with links to page A..

    Good formula, but where did you find that, do you have any official proof about legitimate of this formula ?

    This was a valid formula for computing public PR until 2008-2009. Since then a lot of things happened which proved that Google has twicked the public PR algorithm in order to stop massive link purchases just for the sake of getting PR.
    Currently and due to the above, public PR sometimes shows unexplainable values for many websites. There are rumors that Google still keeps the real "internal PageRank" computed by the old formula for internal purposes, and you cannot access this internal PR via GoogleToolbar or any other means.

    backlinks are useless, i have a pr2 domain with no backlinks or no content on it at all.
    I have a pr1 with a few thousands back links and its only pr1
    and i have another pr1 with like 38 backlinks

    Im guessing its massively to-do with the quality off the content, if its unique ect

    They change the formula every day.

    I think the most important factors are relevant URL, URL age and incoming links in the same niche.

    URL or URL age has nothing to do with page rank...
    it's ALL BASED ON BACKLINKS

    that's it
    get backlinks, you'll get the little green bar

    Thats the truth. I have many customers that have high PR from a few good links.

    The algorithm may be applied to any collection of entities with reciprocal quotations and references. The numerical weight that it assigns to any given element E is also called the PageRank of E and denoted by PR(E).
    [​IMG]

    Page C has a higher PageRank than Page E, even though it has fewer links to it; the link it has is of a much higher value. A web surfer who chooses a random link on every page is going to be on Page E for 8.1% of the time. ( damping factor of 85%.) Without damping, all web surfers would eventually end up on Pages A, B, or C, and all other pages would have PageRank zero. Page A is assumed to link to all pages in the web, because it has no outgoing links.

    Try to read the Google Corporate Information. Google considers many factors for Page Rank. But what is the use of PR, why people still talking about that,
