Seems fine to me....just dont clutter it up with ads like alo of sites do...makes it hard to find ne thing.
looks nice, just would be good to have the images clickable to different pages on the left - good luck!
Would help if the images on the left were links. Also, the navigation bar could be better. How about instead of turning orange, have it underlined.
Looks well laid out. Key words are in place. You dont need adsense because you are looking for customers, not ad revenue. There's nothing really sexy about refrigeration equipment - is there?
