Determining Age of a Domain

I recently bought a domain name that turned out to be an expired domain. This was not something I was expecting and SEO Quake shows the domain age to be 2003. From what I can tell, it looks like the domain was let go in the last part of 2008 and before then it looks as if it was just parked.

The wayback machine shows a couple of different versions of the site in 2003 and 2004, but nothing since then. The two versions looked like they where just a thought and not really built all the way out.

Does anyone know how Google will see the age of this domain. Will it be a brand new domain since I just bought it or could it perhaps be considered 6 years old since it was registered before?

I'm just curious as I've never ran across this type of scenario before.

I believe when the domain expires it loses that age, but i'm not positive on that so I would like to hear some other input on this

if it had any established backlinks then its better than a new one ..
i read somewhere go00gle figures age as 15% in its ranking algorithm
..compared to 15% on authority and remaining other stuff, kws, content, etc.

Well there are no backlinks to speak of other than the few I've built. I'm mainly wondering on this to see if I can get aggressive with building those links without winding up in the sandbox. I'm seriously considering dumping about 10K worth of fresh content in this site and /i'm not interested in getting it sandboxed for six months so I won't be able to get my money back out for over a year

try dnstools.com to check on the domains.

I've looked at a couple of registrars and they are reporting the original date from the first time it was registered. I added privacy on this, so that may be helping with this. I guess I'll just load up senuke and slam hell out of it to see what happens in the serps.

I read somewhere advise do not change the information such as name, address and email at the same time when you buy a domain about to expire since g00g1e will aware of that the owner has been changed if you change all the information at the same time, and they will clear the original rank, external links and PR.

I bought a domain 1 month ago, but it's age shows it is more than 7 years old!!!!!

age does not go back to 0 when domain expires

i use that too..
