How much does the age of an active domain really matter in seo rankings? Or perhaps that is just one of many variables you have to consider so its hard to estimate? Maybe if you are targeting really competitive keywords, than the aged domain might give you a little bit of an edge? I register a lot of domains for my web design clients and some of them will cancel after a while and not want their site or domain any longer so I just let the domains expire. Usually they are not anything special but some have had sites up for 5 or more years. I see people sometimes asking for or selling aged domains so wondering if maybe there is something I could do with these domains instead of just letting them expire?
