If your site is geared around health related products, then DON'T have resources geared towards web design. It just won't fly. Keep graphics to a minimum. Remember that these surfers are very impatient. They want a page to load fast.
Graphics slow it down considerably.
If you use images on your site, be sure to optimize them. This does not affect the size of the graphic, just the file. If your main page is lengthy and takes a while to load, you may need to break it up into 2 or more pages. Be sure each page in your site has links to ALL the other pages. Make navigation easy.
