eBay runs an affiliate program under the name eBay Partner Network.[59] eBay affiliate marketers were originally paid a percentage of the eBay seller's transaction fees, with commissions ranging from 50% to 75% of the fees paid for an item purchased. In October 2009, eBay changed to an affiliate payout system that it calls Quality Click Pricing, in which affiliates are paid an amount determined by an undisclosed algorithm. The total earnings amount is then divided by the number of clicks the affiliate sent to eBay and is reported as Earnings Per Click, or EPC.
