Affiliate Marketing is a revenue sharing venture between a website owner and an online merchant. The website owner will place advertisements on his websites to either help sell the merchant’s products or to send potential customers to the merchant’s website, all in exchange for a share of the profits.

Affiliate marketing is an online advertising channel in which advertisers (online merchants that sell products or services) pay publishers (independent parties that promote the products or services of an advertiser on their Web site) only for results, such as a visitor making a purchase or filling out a form, rather than paying simply to reach a particular audience. This “pay-for-performance” model is in essence the modern version of the “finders’-fee” model, where individuals who introduce new clients to a business are compensated. The difference in the case of affiliate marketing is that advertisers only pay their publishers when the new client introduction results in a sale or a lead, making it a low-risk, high-reward environment for both parties.
Webopedia
Affiliate marketing is the term used to describe a revenue-sharing plan where an online automated marketing program lets Webmasters place an advertiser’s banner ads or buttons on their own Web site. Webmasters will receive a referral fee or commission from conversions when a customer has clicked the affiliate link and performs the desired action, such as make a purchase or opt-in for downloads or newsletters on the advertiser’s site. Advertisers invest in affiliate programs for lead generation, and, of course, sales.
