I was just wondering, does a longer URL registration period have a positive effect on a site’s search engine ranking?
Google has confirmed in the past that both domain age and ownership history may impact the way a site is handled by the algorithm, albeit slightly. But what you’re asking is whether registering a domain for a longer period of time makes a difference to the site’s ranking?
I haven’t researched this for other search engines, but I recall that a couple of people have asked this question in the Google Webmaster forum in the past.
Google staff member John Mu responded that the length of a domain’s registration period does NOT impact how Google ranks the site. As he states, many registrars don’t publish expiration details and so if Google can’t adequately determine when a site expires, they can’t compare it to other sites so they don’t include that as a ranking factor. Besides which, a registration period for a domain doesn’t reveal much about a site.
The content on the domain is much more important from a search engine perspective than how many years it has been registered for.
