The differences between XXX.domain.com and domain.com/XXX?

[andzon]

hi guys i would like to know which seo value is better?

for example if i would put a link in xxx.domain.com or domain.com/XXX which one will give me a better seo value? does it give the same? assuming that domain.com have a huge PR RANK itself.

why do people bother making XXX.domain.com instead?

hope for clarification thanks!

domain.com/XXX is a subfolder while XXX.domain.com is a subdomain

domain.com/xxx is generally better for seo purposes. People use the subdomain as an alternative to creating a new site .

Yeah, couldn't have said it anyway better. domain.com/xxx will be better for your SEO. I would strongly suggest to keep everything on a single subdomain, if you are to look further into the case, Moz did some pretty good experiments on this post: http://moz.com/community/q/moz-s-official-stance-on-subdomain-vs-subfolder-does-it-need-updating
