well the first thing Im seeing right off the bat is google seems to prefer the address you just gave me however that redirects to a subdomain reflecting your desired keyword. When did you do this? I would
A) make sure that you are redirecting properly
B) if its only been a short while give google time to figure out whats going on here
C) make sure that any links that previously pointed to the root domain be switched to your preferred address.
Edit: Take a look at this...
