Are there any advantages to having sub domains?

[emmy]

Hello folks,

I have been wondering and thinking if there is an advantage of using a sub-domain in your forum vs sub-directories in terms of ranking? I know Google and other search engines treat the sub-domains as separate sites and rank them separately, but the sub-domains could help your main domain for already established sites. Any opinion will be appreciated

Thank you

I don't use subdomains unless I am using a blog (IE: blog.yoursite.com) I prefer sub-directories I have never been dinged by google for this either. Then again I have never used sub-domains for anything else. That is just me however.

Google treats directories and subdomains basically the same now. So just use whatever you prefer.
