Glossary Term
Site Age refers to the amount of time during which a domain has existed. Site age is a factor in SEO ranking only as far as content is concerned. If a site has been around for a long time it is assumed that it is constantly being worked on and producing new content. If this is not the case then site age would mean nothing as no credibility was being built. Just because your site is older does not mean it will rank better.
