Affiliate marketing has become one of the most effective ways to advertise online. It is also one of the easiest ways for anyone with a website to make a profit online. Affiliate Marketing is an agreement between a merchant and a website owner. The website owner, or the affiliate, allows the use of their site for the promotion of the merchant's products by linking to the merchant's website. In exchange, the merchant pays a commission to the affiliate on all sales generated by the affiliate. Every time someone clicks on the link on the affiliate website and proceeds to make a purchase, the affiliate gets a commission. The merchant will pay the affiliate only when a customer clicks on the product link and makes a purchase.
