I've thought for quite a while now that the age of a domain (if it's been on the same IP and hasn't changed ownership) plays a large role in how a website ranks. (The influence of this fluctuates month to month, though, I think.) Anyway, do you think by now they've gotten this to the page level? That is, if a single page has been around a long time with the same URL, is it given more weight by Google in the algo in your opinion? Thanks.
Yes its proven. Thats why people pay alot of money for old domains in the buy sell trade section. Like iBoy's sig says: Old Is Gold!
If you do a Nslookup for www.google.com. I got Name: www.l.google.com Addresses: 66.249.93.99, 66.249.93.104, 66.249.93.147 Aliases: www.google.com For every region there is a different ipadress. I think Ipadress doesn't matter but Domain age is very important.
