Affiliate marketing involves a business tapping into the audiences of affiliate websites by providing content like voucher codes or cashback offers to be promoted. Affiliates are rewarded with commission for each sale driven. Traditionally, voucher code sites have built large followings by offering discounts and savings. Cashback sites also form a major part of affiliate marketing, passing a percentage of commissions back to customers. More recently, retargeting affiliates that remind visitors of abandoned carts or serve ads after site visits have proven effective at securing last click conversions. Bloggers have also become prominent affiliates but often do not earn commission due to savvy readers using cashback sites for deals. At its core, affiliate marketing rewards third parties for securing last click conversions
