The key here is getting people to sign up. How do you do that? By showing their video to people who are looking for a way to earn some extra cash. And that's it. But as with any online business opportunity, that is where most people fail. They don't know how to generate the necessary traffic needed to watch the video. And that is where the wealthy are set apart from those who don't make money online. They know how to generate enough traffic to succeed, no matter what business they choose to promote.
