I have a blog currently hosted at mydomain.wordpress.com but reachable by blog.mydomain.com and have been told this is not helping my SEO credibility. I've been told to switch to mydomain.com/blog but don't know if I can point a subdirectory at a site hosted elsewhere. Is this possible? Will it actually improve my SEO ranking/credibility?
Current Setup
//Hosted at:
mydomain.wordpress.com
//Domain Mapped to:
blog.mydomain.com
Desired Setup
//Hosted at:
mydomain.wordpress.com
//Domain Mapped to:
mydomain.com/blog
