Affiliate marketing is an advertising model in which a company compensates third-party publishers to generate traffic or leads to the company’s products and services. The third-party publishers are affiliates, and the commission fee incentivizes them to find ways to promote the company.
The Internet has increased the prominence of affiliate marketing. Amazon popularized the practice by creating an affiliate marketing program whereby websites and bloggers put links to the Amazon page for a reviewed or discussed product to receive advertising fees when a purchase is made. In this sense, affiliate marketing is essentially a pay-for-performance marketing program where the act of selling is outsourced across a vast network.
