I place emphasis on the “interested” aspect, as you may end up sticking with this topic for an extended period of time. As we’ve said previously, successful affiliate marketers are more likely to receive opportunities to sell other products in the future. In the same way you don’t want to build up a resume full of jobs you hate, don’t sell products for an industry that means nothing to you.
Affiliate marketing is commonly confused with referral marketing, as both forms of marketing use third parties to drive sales to the retailer. The two forms of marketing are differentiated, however, in how they drive sales, where affiliate marketing relies purely on financial motivations, while referral marketing relies more on trust and personal relationships.
