    Pay attention to this "In the present invention, it is possible, therefore, for a document with only one backlink (from a very highly ranked page) to have a higher rank than another document with many backlinks (from very low ranked pages). This is not the case with simple citation ranking."

    Quality, not quantity!

    "Consistent with the present invention, there are several ways that this method can be adapted or altered for various purposes. As already mentioned above, rather than including the random linking probability α equally among all nodes, it can be divided in various ways among all the sites by changing the 1 matrix to another matrix. For example, it could be distributed so that a random jump takes the surfer to one of a few nodes that have a high importance, and will not take the surfer to any of the other nodes. This can be very effective in preventing deceptively tagged documents from receiving artificially inflated relevance. Alternatively, the random linking probability could be distributed so that random jumps do not happen from high importance nodes, and only happen from other nodes. This distribution would model a surfer who is more likely to make random jumps from unimportant sites and follow forward links from important sites. A modification to avoid drawing unwarranted attention to pages with artificially inflated relevance is to ignore local links between documents and only consider links between separate domains. Because the links from other sites to the document are not directly under the control of a typical web site designer, it is then difficult for the designer to artificially inflate the ranking. A simpler approach is to weight links from pages contained on the same web server less than links from other servers. Also, in addition to servers, internet domains and any general measure of the distance between links could be used to determine such a weighting."

    This means that if google finds an indication that a website linking to your site is in someway affiliated with your website then they will factor this into your ranking. (reduce the power of the backlink)

    Additional modifications can further improve the performance of this method.Rank can be increased for documents whose backlinks are maintained by different institutions and authors in various geographic locations. Or it can be increased if links come from unusually important web locations such as the root page of a domain.

    Root domains, geographical location. Any feel the .edu arguement rising up again?

    I can't believe nobody's replied to this.

    Great info. Not a lot of it is 'new' knowledge, but it dispels anybody's statements about things like the quality of backlinks and such.
