I have purchased a domain 7 years old in age, PR 1 from godaddy auctions, Web designing niche. Now if i put a 301 redirect to it, & apply for a change of address using webmaster tools, Will it pass the domain age of 7 years to my 2year old domain? What do you think is the SEO benefit of doing this? Is it worth doing it? or should i build a site on the 7 year old domain? Do Godaddy expired domains that are auctioned pass on any value?
