How can I link subdomains to my main domain to get the SEO benefit? I've seen examples using all sorts of clever redirects and PHP where you get the subdomain's content on the main site...but what I want is for the subdomain to be linked with the main domain; I don't mind it sitting by itself, but I'd just like to get the SEO benefit of it. I'm aware that Google see subdomains as separate domains but can change / help them to be seen more as one site?
