How come the age of the domain doesn't show up in google SEO for firefox?

[Minestoned]

I'm thinking of buying an aged domain. Never done it before. I'm looking at http://www.aged-domain-finder.com and also the godaddy domain auctions, they have a list of aged domains, but when u check it in google using SEO for firefox, it doesn't show up. How can i get a real aged domain so i can rise in page rank faster?

usually one uses the whois data to determine the age of a site, the form is different for different domainers making it tougher to automatically extract it.

There's a paid domain auction monitoring service that has a free trial period, sorry the name's not in front of me. Google domain auctions is one it watches.

The rather pricey tutorial package, Commission Blueprint II that went into some detail on buying pr-3 domains for an average cost of under $30.
