It’s worth noting that domain age isn’t referring just to how long you have owned a given domain name, but instead how long it has been since Google first indexed that domain, or saw a link to the domain. Because of this many companies purchase “aged” domains that have been around for a while for the extra bit of Google oomph. Of course just because a domain has been registered for 10 years doesn’t mean that Google considers it 10 years old — it has to have actually had a site indexed by Google.In other words a domain that’s been registered for 10 years but has no actual site up, or nothing that Google has ever found, is the same as a domain that you bought yesterday.
