• APPROACH THE AFFILIATES -- With affiliate networks, you promote a product or service from an advertiser on your site through banner advertising and earn a commission every time a user on your site purchases that product or service. Companies like American Express, Bank of America, McDonald's and Barnes & Noble place ads through affiliate networks. This is also known as the cost-per-action revenue model. Commissions to publishers from top affiliate networks usually run between 3 percent and 15 percent of the sale, but they can run as high as 50 percent on some affiliate networks. Check out affiliate programs run by Commission Junction, LinkShare or Amazon to learn more.
