This is the affiliate program of the world’s leading auction site. Ebay’s affiliate program was previously run via Commission Junction, but they split from their umbrella affiliate partner in 2008 to launch their own affiliate program. Ebay pays a hosting web-site each time a visitor to the site “clicks-thru” and makes a bid or purchase on Ebay, or registers as an Ebay user. The program offers affiliates multiple ways by which they can make money via Ebay.
