Affiliate Marketing is an Internet-based marketing practice in which a business rewards one or more affiliates for each visitor or customer brought about by the affiliate's marketing efforts. It is an application of crowdsourcing.[citation needed] Examples include rewards sites, where users are rewarded with cash or gifts, for the completion of an offer, and the referral of others to the site.

The affiliate marketing industry has four core players: the merchant (also known as 'retailer' or 'brand'), the network, the publisher (also known as 'the affiliate') and the customer. The market has grown in complexity to warrant a secondary tier of players, including affiliate management agencies, super-affiliates and specialized third parties vendors.
