Commission Junction — This site serves as a clearinghouse for thousands of companies and small businesses looking to get into the affiliate business. It offers myriad affiliate programs, but you must apply separately to each one. Payout rates vary wildly, up to 50 percent, and some commissions are based on leads or clicks vs. sales. Frustratingly, Commission Junction deducts $10 from your accrued earnings for every month in which you don’t actively earn commissions; if you let your account lapse, your income could get wiped out.
Affiliate marketing currently lacks industry standards for training and certification. There are some training courses and seminars that result in certifications; however, the acceptance of such certifications is mostly due to the reputation of the individual or company issuing the certification. Affiliate marketing is not commonly taught in universities, and only a few college instructors work with Internet marketers to introduce the subject to students majoring in marketing.
Affiliate marketing overlaps with other Internet marketing methods to some degree, because affiliates often use regular advertising methods. Those methods include organic search engine optimization (SEO), paid search engine marketing (PPC – Pay Per Click), e-mail marketing, content marketing, and (in some sense) display advertising. On the other hand, affiliates sometimes use less orthodox techniques, such as publishing reviews of products or services offered by a partner.
