An affiliate marketer is someone who promotes a product or service to potential customers, in exchange for a commission on the sale when one occurs.

For example, letís say Alan is an avid gardener. He buys a great eBook through Bob's online bookstore about growing bigger roses, and wants to recommend it to others. He signs up for a free affiliate account with Bob's online bookstore, then finds the eBook about roses in the product promotion page and creates a customized link. He posts this link in places where he thinks people would be interested in the eBook, such as a gardening forum heís a member of, his gardening blog, his Facebook profile, even in an email to some of his gardener friends. The possibilities really are limitless.

If someone clicks on his link to learn more about the eBook and ends up purchasing it, Alan gets a generous commission on the saleó as much as 75%, depending on the product
