Ever wonder how Google's site ranking works? Wonder no more. Google recently filed United States Patent Application 20050071741 on March 31, 2005. This patent reveals a great deal of information about Google's site ranking algorithm and makes very good reading. For example, one of the criteria that they use is the number of years that your site has been registered. If your site has been registered for less than a year, then it counts against you. A site registered for a longer period of time means that the owner is probably serious about the site, and the site is probably legitimate. Google's Site Ranking algorithms reveal how hard they are making it for spam sites to get listed (on Google). This information will also make it easier for you to make sure that you get listed well in Google.
