Affiliate marketing is the promoting of products that other people make or for businesses like travel, finance, credit, etc. Marketers publish links online on multiple sites. Affiliates promote your products, and once they make a sale, they earn commissions. Affiliate marketing is successful because many new customers see your products. The customers' interest is peaked when he or she sees a product over and over again. There are two ways of doing affiliate marketing. Either start your affiliate program or become another company's affiliate. For every sale that you make because of affiliate efforts, you pay a commission. Should you opt to have your affiliate program, every purchase means that you pay a commission.
