This method is very effective and I've been using this way to make money for over a year now. It will take time at first, if you don't invest in a program or have any knowledge in developing a small youtube program to help you get started faster. I don't make 50 dollars a day, but a few hundred dollars ever couple of months yes. Like ferma321 said, uploading many videos will get you more results. Just make sure each one is unique and professional, best advice I can give
