For those new to this powerful online merchandising concept, affiliate programs work as intermediaries between the affiliate marketers who will sell products and services and the merchant who provides those products and services as well as the affiliates programs. Merchants work with affiliates to help get their products or services to their consumers.
In addition, you must know how much you want to earn by joining affiliate programs. Will it be your main source of income or just an additional one? For the first scenario, you should consider promoting products that are expensive and, consequently, that can bring you a good profit. If you plan on the second scenario, you can opt for affiliate programs that pay for sign ups or affiliate programs that pay daily.
