Google patent indicates domain registration length a factor

Google's patent indicates that the length that a domain name is registered for can be a factor in determining the ranking of your site.

Although this is only one of many factors that are in Google's patent it still plays a part in how Google evaluates a website. According to Google if a domain name is registered for a long period it shows the owner tends to be more serious about their venture.

Often domain speculators, the use of doorway pages and other nefarious activities will more likely be associated with domains registered for a short period such as a year.
