Unfortunately, the 2Checkout dashboard is a bit limited in scope, making it difficult to get any metrics on conversion rates or even sorting by commission payouts. The workaround is to go to the Avangate store, which does list their best-selling products, and then search for these on the affiliate dashboard. That being said, 2Checkout does offer products from more than 4,000 different vendors, making it the leading affiliate network for software and digital products.
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.
