I don't understand is it some kind of link exchange that you have to add some html markup to your website? And also pay a monthly fee? I didn't understand that from the video. Also, what are the estimates of traffic you're going to get? Is it connected how many times you show other people's ads on your site etc? And what does the 17 year old Africans have to do with the link? It's not a news article about their success story but their product. (I assume)
