What is affiliate marketing? Affiliate marketing is simply a way to make money online by promoting a service, product or a site that isn’t yours. As an affiliate, you are rewarded on a performance-based structure that allows you to earn money based on your advertising efforts. For example: If you promote a product from Amazon and someone makes the purchase by clicking on your link, you earn a percentage off the total sale. They have an affiliate program called Amazon Associates, and you can promote any product. You basically get a link that has your specific affiliate code on the end of it.
