Affiliate programs are a marketing arrangement by which an online retailer pays commission to an external website for traffic or sales generated from its referrals. It is a method of selling products or services by marketing them within the content of websites, like Holonis. Affiliates (also known as publishers) earn a commission from their merchants for every sale or other pre-agreed action, such as subscriptions, delivered through their efforts.
Simply put, you find a product you like, promote it to others and earn a piece of the profit for each sale that you make.
This method is called performance-based marketing or pay-per-action marketing (PPA). It is a modern variation of the practice of paying finder's fees to individuals who introduce new clients to a business. Compensation can be based on generating sales, completing forms, or signing up new customers.
