Google's exact match domain SEO boost is well publicised (including in a recent Stack Exchange podcast). But is there any evidence that an "exact match subdomain" gets any kind of boost?
I'm talking about the difference between word.example.com vs wordexample.com (and maybe word.com/example) in a search for "word example".
(Note: I'm not actually considering using this technique, I just heard someone mention it and am interested if there is any evidence for it.)
