shaunm, i think the Problem is that the adwords tool shows also similar searches ( on the left side u have to uncheck "similar") and only 1 key searches. Most poeple donīt search only one word.
SO your site might be usefull for the keyword itself but in regard of the query / search history / physical and psychical constitution of the searcher ( what i think Google might think it could guess ) your site does not match.
Theres is a lot of adwords/Shopping ads on the Google page too.
