Question about Adsense and Keywords
 

You need to make sure that all your produces are represented on your home page in the way of text within the body of the page. Also, mention your products in the H1 heading at the top of the page. Next, make seperate pages loaded with your product keyword and make the url represent the product as well. Seperate pages with url mentioning your individual products should help with getting the proper ads. The H1 title and URL plus the page text seems to be major components in the ads on your pages.
