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
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.)
