Paid ads should be your last step in marketing your range of affiliate products. You want to make sure you’re in a money-making niche and have a roster of products proven to sell, as well as proven sales funnel that compels your prospects to buy. That way when you invest the money in a paid ad, which can cost hundreds and thousands of dollars, you’ll see a decent return on investment.
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.
