Google's Patent Application contains a lot to read and reading it may take some time, but if you own any type of website, this is all information you need to know. It also brings some interesting points up. While I go over some of the important points, know that no one knows which of these factors is given more weight than the others.

Domain Name Registration - Google is now going to track when a domain is registered among other things. An older domain will get a higher ranking. No more throw away domain names. No more jump to the top of Google results in thirty days.They will also be tracking the length of renewal on the theory that a person that renews for ten years will be more likely to build a worthwhile site than someone who only holds their domain for a year.
