adMarketplace's pay-per-click ad management service, AMPkeywords.com, is no longer exclusively for eBay sellers. The service now offers all online advertisers the opportunity to advertise on its network of web site publishers, as well as remaining integrated with eBay for the benefit of eBay sellers advertising with them.

AMPkeywords.com also announced a unique feature that helps protect against click fraud by using conversion data (the ratio of clicks to sales) to monitor the traffic sent through to advertisers.

AMPkeywords.com had a three year exclusive relationship with eBay which ended in October 2006. They provided a service called eBay Keywords which enabled eBay sellers to advertise on eBay itself using keyword-targeted cost-per-click advertisements. eBay no longer shows ads from eBay sellers.
