Do search engines prioritize blogs more with age?

[Jake]

A brand new site does have to earn respect, realistically a new site doesn't have much of a following, and because few people are visiting it, there are relatively few links being made to the site, active SEO campaigns have to go easy those first 6 months or so.

Some people buy aged domain names at auctions so they can start with a site that appears to already have age.

The age factor applies to any site, blogs in particular are liked because they are assumed to have regular new content additions, you need to stay on the job to grow search raking.
