From September 1st 2009 for new publishers and October 1st 2009 for existing publishers, eBay Partner Network will replace the current CPA (Cost Per Action) system of directly paying for new users and bids or revenue with a new payment model called Quality Click Pricing.
With Quality Click Pricing, we will pay publishers for clicks sent to eBay sites and the amount paid per click (EPC) on a daily basis will depend on the traffic's quality. The quality of traffic will be assessed using a number of different factors, including revenue from sales and the long term value of new users, as today, but also eBay advertising and PayPal revenue and other user behavior factors. Essentially, the more incremental revenue your traffic generates for eBay, the more you'll be paid per click.
