In its simplest definition, it is a relationship between an online merchant or retailer, who has products to sell, and his affiliates, who are willing to promote the merchant's product on their website.

In a typical affiliate marketing set up, the merchant provides his affiliates with banners and text ads that link to his site. They will then get these ads posted on their website and they get paid whenever traffic or sales is directed to the merchant's website.

Affiliates are often paid on commission basis, although other online merchants would opt to pay a fixed fee for the affiliates compensation.

There are actually a number of ways for you to earn money as an affiliate, and most of these ways depends on the type of program you have gotten into. Some affiliate marketing programs are two-tier programs and some are one tier programs.

Starting to make money online with affiliate marketing is relatively quick and easy. All that one has to do is to sign up as an affiliate for an online company that offers affiliate programs. After signing up with an affiliate program and being an actual affiliate, you are now ready to start making a lot of money by selling other people's product online.

With a lot of options available and a lot of ways to earn money, affiliate marketing is undoubtedly the most popular and the easiest way to make money by selling other people's products online.
