I have an enhanced listing at the landing page for my category, watches. Because search is so bad (try to find watch in search) the only way to find a watch is to drill down through Avatar Accessories categories to watches. And there I am, top row! I have had the enhanced listing for my top seller since Marketplace opened and it has proved very successful to me. I tried a few short term enhancements around Christmas. Ones on the Watch category landing page produced results. Otside the category, not so much.
