subdomain.mydomain.com or www.mydomain.com/subfolder

Is there any benefit of a subdomain over just using a subfolder?

Hi seoerer, welcome to Webmaster World!

I think it looks more professional to have the subdomain in front, but that's just an opinion.

It might matter to search engines but I'll leave that to the other SEO people on the forum.
