Pay-Per-Click is also considered as widespread and common affiliate agreement. Under this agreement, the affiliate marketers will get fixed rates depending on the number of clients who click on the links placed on the affiliate website that leads to the merchant website. Here a purchase is not necessary to earn commissions, all that has to be done is that the client clicks the link and stays at least thirty seconds on the merchant website. Regardless of what the visitor does on the merchant site, this will not affect the commission.
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.
