which is better?

[goneinthesun]

hope i am posting in the right place. Want to thanks admin ahead of time for moving it to the right location if i am wrong.

I am thinking of add a forum and blog to my directory site.

is domain.com/forum or forum.domain.com better for seo reason?

any advice is great.

forum.domain.com will be treated as a completely different site to www.domain.com

www.domain.com/forum will mean that it is all treated as one site.

So horses for courses, depends on what you are trying to achieve
