Affiliate marketing is the process of earning a commission by promoting other products. Affiliate marketing is the king of all money-making sources for almost every blogger and marketer. Once you master the art of turning your traffic into sales, affiliate marketing helps you make money even while you sleep. You don't have to work very hard for every dollar you make unlike any other source. Once you set up your own traffic conversion funnel, it sends you payments whenever someone buys from your affiliate links. That's the beauty of affiliate marketing.
