The idea behind this is very simple, just copy a code on your site and submit your site on it. Your link will be displayed on every site that is using the promotion box. So when 100 people are using this promotionbox, and they all have 50 visitors a day, your site can get 5000 visitors a day. Just think about what can happen when 1000 webmasters use this tool :) Just place the code on your site for 1 week, and see your visitor count grow everyday!
