Are domains really "Aged" if they are just parked?
 

What if the domain is just "registered" and not even parking page? How does that help anything if there is no content there? Someone please explain!

Content is one factor and length of registration is another of many.

Matt Cutts kind of dances around the topic imo here...sounds like he is talking more about the length of registration vs age of domain...??

They are not aged if they are not indexed. A domain can be 10 years old, and if it was never indexed it won't matter. The problem is Google is erratic on how it indexes domains that are on a parked page, especially if it's the registrar's parked pages...

The Age of a domain in current SEO, has almost no weight at all. It used to, tho.

age of domain helps to index site fast ,i mean millions of pages can be indexed within a month with aged domain.

and

indexed domain is another thing, it will help you rank ......

Wouldn't bank on it, bro.
