By quite a large margin Amazon has the largest affiliate marketing program out there, with products from more than 1.5 million sellers. Amazon has the most easy-to-use technology of all the affiliate programs I will be reviewing today. Beginners to affiliate marketing with even the most limited technical expertise will have no problems in getting up and running with the Amazon associates program, while more experienced marketers can create custom tools and websites with the APIs and advanced implementations available to them. The great thing about Amazon is that anything from kids toys to laptops can generate sales if they are purchased through any Amazon affiliate link.
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.
