Affiliate Marketing is the process by which a person or company called an “affiliate” earns a commission for marketing another person’s or company’s products. Affiliates are “commissioned” independent sales people that simply search for products they like or enjoy, then promote that product typically on a blog or a website. For their promotion, they earn a piece of the profit from each sale they make. Sales made by affiliates are tracked via something called “affiliate links” from one website to another.
