Affiliate marketing is an online sales tactic that lets a product owner increase sales by allowing others targeting the same audience—“affiliates”—to earn a commission by recommending the product to others. At the same time, it makes it possible for affiliates to earn money on product sales without creating products of their own.

Simply put, affiliate marketing involves referring a product or service by sharing it on a blog, social media platforms, or website. The affiliate earns a commission each time someone makes a purchase through the unique link associated with their recommendation. Done well, this performance-based opportunity can become an important part of your business by netting you a healthy income.
