Many users previously purchased expired domain names that used to house an older popular web site in the interest of tricking search engines into thinking a site is not new. Search engines are now aware of this practice and reset the "aging-value" of any site that is housed by an expired domain name, as well as devalue its preexisting links. In fact, there many also be a penalty applied to such expired domain names. There are still opportunities, however, in buying domains directly from users with old existing web sites.
Time-based factors that are used as ranking factors are the site and page age, and the age of the links refering to it. The registration length of a domain name may also influence rangkings.
