Nobody knows for sure exactly how it works, but it has to do with inbound links and the quality of the inbound links (how relevant is the site that links to You to Your site ie. a babyfood manufacturer linking to a porn linklist would be very irrelevant but a buttplug manufacturer would be relevant "something like that") to your website.
