Hi forum folks,
I use to think that domain age was important to, until lately. I was building a site for my employer and he dabbled on the domain name. 2 weeks ago we bought the domain name and now the site is listed on page 5 without any submitions, sitemap, or any SEO. I noticed this as well on another site when the domain name was less than 1 week old and listed high in google. This kind of abnormalities do make you ponder.

However, in answer to health2u I do agree with all the above comments and say that the domain name will help you bump up a little in the SERP, but do not forget all the fun SEO stuff. And for now let your domain name age a little.
