Search engines consider links as "votes" for the suitability of web pages to show up in the search results. If you're serious about making money from your lists, you have to do linkdev (link development). Link to your lists from your blog, your profile pages, your personal sites. Share your list with friends who have blogs, and tell them to link to it. Submit it to sites like Digg and Stumbleupon. DO whatever you can to create buzz, links, and traffic for your lists.
