An affiliate marketing company is an online business model in which an individual or organization (the affiliate) earns a commission for marketing another person or organization's products, services or platforms.

Affiliate marketing companies bring together merchants who want to sell their products or services and affiliates who market these products. These companies are responsible for connecting the two parties, tracking sales and paying the affiliate their commissions. The affiliate marketing company acts as a middleman, tracking customer activity and giving merchants the opportunity to reach a larger audience while giving affiliates access to thousands of products and services to market.
