How do I optimize a db-driven e-commerce site for search engines? The merchant knows that a search for, say, "widget" will get 1000&#039s of results on Yahoo, but is hoping that in a search for "red super-mega-widget", or his less-common products, his site will have a better chance. Is there any way to get web crawlers to rate the product info and other content that is in the db? Is there something I can do with text files?
