Website affiliates are what drive Internet marketing. Companies run affiliate programs to generate leads and sales from other Websites. They pay the sites who host their ads a commission for products sold through the links on their sites. For example, if a site owner signs up for Amazon.com's affiliate program, he will receive ad banners or links from Amazon.com that he can place anywhere on his site. Then, if a visitor clicks on the Amazon.com banner or a link on his site and buys something, he will receive a commission. Unfortunately for Website owners, affiliate commissions are seldom above 5%, since most Web sales are made with small profit margins.
