One of the most exciting developments of Internet marketing that is making many entrepreneurs rich is affiliate marketing. Affiliate marketing could be the future of marketing and replacement for much of traditional paid advertising because affiliate marketing only cost the advertiser when the advertising is effective. In any affiliate program there is a host web site and affiliates. Affiliates advertise for the host web site using banners, text links, and e-mails with embedded text links and when a web search surfer clicks through from an affiliate link to the host site and makes a purchase the affiliate is paid either a set fee or a commission based on the affiliate agreement.
