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?
thanks

Why don't you check the Whois information where you can find the exact information about age of domain. Use WHOIS Lookup and Domain Name Search | DomainTools.com

Go to the Firefox homepage and download SEOQuake and SEMRush plug-ins (might have to go to SEMRush website, can't quite remember). Possibly the best toolbar to use.

just go to opensiteexplorer.com to check your domain authority....

SEO Quake tool shows the age of a site.
