Recently a thread at Cre8asite restarted the discussion on the long standing issue of whether the age of the domain significant in obtaining a good rank with Google. Some time back Jim Boykin tried to explain the relevance of age.
The thread did not bag many responses but a couple of them stated that age was one of the factor. Another reply stated, “If you're looking to purchase an old domain simply to get out of the "sandbox" / "trustbox" then look for one that has links going to it still and has had content on it for some time through archive.org. That will increase your chances… but "buyer beware"… some old domains are being resold because they've been blacklisted or have been part of spam schemes and those domains are worse off than a brand new domain.”
Another reply expressed, “I also believe (and google's mentioned in a patent) that they record the date that they find any new link to your site (as well as the text used in that link). So if you have an old site, but there's only been 10 links to it over 5 years that might not be worth much….not nearly as much as a site that has a good history of "a natural resource page link growth."
The debate still goes on whether it is the age that matters or the rank id affected by the content.
