"News Brief
AMP Keywords No Longer Exclusive To eBay
Tuesday, Apr 10, 2007 6:00 AM ET
BEGINNING TODAY, ADMARKETPLACE'S PAY PER Click management service, http://www.ampkeywords.com, ends its exclusivity with eBay and offers all online advertisers the ability to gain customers from its conversion-optimized inventory.


AMPkeywords.com is the first automated service to use conversion data from all clicks it delivers to protect against click fraud and to ensure that it delivers high-quality traffic to advertisers at the lowest cost. For small and mid-size advertisers particularly, this Cost Per Action-style optimization service is a cost-effective way to obtain SEM services ordinarily provided only to large marketers with high monthly budgets.

While AMPkeywords.com remains fully integrated with eBay, it now allows any online marketer to send customers to their own Web site."
