Promoting affiliate programs is the least costly and least stressful of all types of home Internet businesses and makes an excellent starting point for Internet marketing novices. It is also one of the best ways to earn revenue from your web site if you don't have a product of your own to sell. In fact, there are some 'super affiliates' out there that make their living online doing nothing but promoting other online merchant's products or services through affiliate programs. So, just what is an affiliate program? An affiliate> is someone who partners with another online merchant to help drive targeted business to that merchant's web site in order to increase sales. An affiliate program is an inexpensive marketing strategy used by an online merchant in which a monetary incentive is offered to webmasters (affiliates) to drive traffic to that merchant's web site. The monetary incentive is usually in the form of a percentage-based commission or a fixed dollar amount. Affiliate programs are sometimes referred to as associate programs or referral programs. Affiliates are also referred to as publishers in many cases.
