Welcome to the Q&A Forum

I agree with Andy, except that I would set the categories and the navigation bar for usability over pleasing the search engines. Blasphemy, I know on an SEO Q&A forum. Seriously, though, your #1 goal is to keep it as simple and uncomplicated as possible for users to find your products. SEO aids that, but it is not the goal in and of itself. The goal is more clients/sales/users. If you haven't done this already, put your categories/navigation sections on 3x5 cards or sticky notes, and then arrange them on a table or wall. Cross-reference the navigation words you are using with the search terms by which people look for this product to make sure they are user-friendly What taxonomy works and would make sense to your users in terms of getting to your products the easiest and fastest? Then use that one. A complicated taxonomy that makes sense to robots but not to people will increase your bounce rates and not your sales. So...go for the users. -- Jewel
