I found strange words, (have, here, imagery, sorry) that were supposed not to be on my site, being taken as keywords by the crawler from Google
Did you try to add spider meta tags , it really helps a lot try this out in the head section.
The spider will now index your whole website, also will not only index the first webpage of your website but also all your other webpages.
Also try to make you description more unique! much more powerful but not to overdose those keys.
thanks
