    Hey,
    I know this is much complicated than what I post here. But thats all I could find with 5 hrs of searching the net with Yahoo, MSN, Altavista and some others. There were some other articles but they did not have any formula.

    Maybe this is useless but I still would like to share this with you.

    :) :)

    GoogScore = (KW Usage Score * 0.3) + (Domain Strength * 0.25) + (Inbound Link Score * 0.25) + (User Data * 0.1) + (Content Quality Score * 0.1) + (Manual Boosts) - (Automated & Manual Penalties)

    KW Usage Factors:

    KW in title tag
    KW in header tags
    KW in document text
    KW in internal links pointing to the page
    KW in domain and/or URL
    Domain Strength

    Registration history
    Domain age
    Strength of links pointing to the domain
    Topical neighborhood of domain based on inlinks & outlinks
    Historical use & links pattern to domain
    Inbound Link Score

    Age of links
    Quality of domains sending links
    Quality of pages sending links
    Anchor text of links
    Link quantity/weight metric (Pagerank or a variation)
    Subject matter of linking pages/sites
    User Data

    Historical CTR to page in SERPs
    Time users spend on page
    Search requests for URL/domain
    Historical visits/use of URL/domain by users GG can monitor (toolbar, wifi, analytics, etc.)
    Content Quality Score

    Potentially given by hand for popular queries/pages
    Provided by Google raters (remember Henk?)
    Machine-algos for rating text quality/readability/etc

    I think this probably gives a good summary of the main factors.

    But in my opinion the "content quality" should be the most important factor of all, if there were just a good way to measure it.

    Content quality is very important but a lot of the other factors are theoretically a symtpom of good content quality. For example, if more people click thru to a page or spend longer on the page then Google might presume the content is good/ worth ranking well.

    That blog post is a bit old now, they will have changed the Algorithm a lot since then.

    Good find anyway.
