How do I estimate the value of domain age?

[mhdoc]

I have many domains coming up for renewal with creation dates three or four years ago. Most are not great name since they have hyphens and/or are not dot coms.

For example, Automobile-Repair.net was created in 2006 and I never got around to putting a site on it. I am not really looking for an appraisal of that particular name. What I hope to get are general comments about the importance of age to the value of non-premium domains.

As a enduser age is not important to me if i like the domain and i want use it for years.

I've ready Google is giving a "pagerank bonus" for domains indexed for more than 5 years within the same keyword area.

So I'd give a similar valuation bonus for domains that reach that threshold...

I would check of course that domains have not been parked or used with different keyword profile during that time...
