How to earn by affilate marketting?

Affiliate marketing is something looks easy at first view. Basicaly, you promote and try to sell a product which you didn't make it, you didn't pay for it, you don't have it and is not yours in any way. Simple send potential buyers to where the product is for sale. In reality is not so simple and the best short program to learn affiliate marketing and how to use it is a 30 days course I once buy it with PLR. The main problem is that "briefly", "shortly", "work 1 hour a week and earn 3 billions every 5 minutes", all those are hypes or ... scams. There is no "overnight" and there is no "free" and there is no "do nothing". If you want more details, ask me in private.
