One SEO opportunity that most stores are not capitalizing on the ability to rank well for your actual product names. These tend to be less competitive terms and have a very high conversion rate. One thing that helps to rank well for your exact product names is to have lots of links pointing to each of your product pages, something a default Yahoo! Store does not have. This product adds links at the bottom of each product page to every other product in the same section. That way every product gets links to it from every other product in the same section, helping your product pages to rank better.
