What is affiliate marketing? Simply put, affiliate marketing is when you advertise some product or service, and get paid a commission for every sale that is made through your affiliate link.
An affiliate link is a special link you get from a person or company, whose service or product you will be advertising. That link belongs only to you. So when someone clicks on it, a so-called “cookie” is stored on the person’s computer. And whenever that person makes a purchase, that cookie will show that it was you who helped to make the purchase.
