Domain with directories or new domains?

what is better, a domain with subdirectories or whole new domains for those directories?

I have a website divided by 12 directories which are the main purpose of the website开发者_如何学JAVA like: example.com/subject1

example.com/subject2

I was wondering what is better for me, new domains for subject1 and subject2, like subject1.com and subject2.dom etc or keep it as folders?

or new domains that points to the main domain /directory?

Thanks,

Joe

Depends if you want to keep them as separate entities or not, which would depend on your goals.

subject1.example.com and subject2.example.com both point to example.com, so any marketing efforts all serve to build up example.com, but you only have one site.

If you want to build them up as separate entities, then subject1.com and subject2.com are the way to go, but that means your marketing efforts are split between them.

On the back end, it's no more difficult to point the directories on your space to separate domains than it is to point them to subdomains of one common domain.
