Hi I've read somewhere that Google looks at the length of time a domain is registered for and uses that in their ranking algorithm. If a domain has already been registered, will extending the lenth of registration make any difference? Bill
Yes, they'll look at both how long it has been registered for, and how much time is left on the registration. It's debatable how much influence this has on a site's ranking; content and backlinks are more important, but it won't hurt to extend your site's registration as it shows you're serious about the domain.
