Affiliate marketing has become one of the most reliable methods to advertise online. It is also among the simplest ways for anybody with a site to earn a profit online. Affiliate Marketing is a contract between a website and a merchant owner. The site owner, or the affiliate, permits the usage of their site for the promotion of the merchant's products by connecting to the merchant's site. In exchange, the merchant pays a commission to the affiliate on all sales generated by the affiliate. Whenever someone clicks the link on the affiliate website and continues to buy, the affiliate gets a commission. The merchant will pay the affiliate only when a customer clicks the item link and buys. Are you a web designer who needs funds to keep your site running?
