Affiliate Marketing works well if are you are doggedly persistent, very disciplined and know exactly the strategies that work. You have to treat this as a business and it requires a good deal of study to get it right. The key is to get the right information and not be led down a blind alley by scam artists who only make money selling garbage information and whose only purpose in life is to separate you from you money. Some of the best, most comprehensive courses I have seen on affiliate marketing are written by a fellow named Saj P. His materials tell the truth, and tells you what works, but it's not for beginners. Some of his courses are Affiliate Payload, Affiliate Funnel System, The Site Rush, see below.
