Affiliate marketing has been a heavily used buzz word around the cyber world for a while now, but there is a reason for that. It has consistently been one of the easiest, and quickest, ways to generate passive income. In a nutshell, affiliate marketing is a way to share revenue between someone who owns a website and someone who has an online business or product. The website owner places the ads for the business and they share the profits from any resulting sales. It is a way to help online marketers generate cash flow so that they can stay in business.
