Affiliate marketing is performance-based marketing in which a business rewards one or more affiliates for each visitor or customer brought by the affiliate’s marketing efforts. For example, the company might pay the affiliate a certain percentage of any sale resulting from the customer clicking on the affiliate’s link. Businesses should consider affiliate marketing because it effectively drives traffic to their website and generates leads. It also costs less than advertising, as the company only pays the affiliate when a sale is made. Furthermore, because affiliates are only paid when their marketing efforts produce results, it is an effective way to ensure the business receives a high return on investment. Finally, affiliate marketing offers access to an extensive network of websites, allowing the company to reach a broad audience.
