Mpire has rolled out an ad option for its WidgetBucks ad network, reports MediaPost.

The network, YieldSense, displays ads based on the content of the site. Next, the system determines what sorts of ads work best, then deliver new ads appropriately.

Ad delivery will also be determined by visitor's location.

Mpire sells YieldSense solely on a PPC basis. It includes widget-based ad products that alternate between PPC and CPM models.

The range of choices does not belong to the advertiser. Instead, WidgetBucks determines the best options for its clients, based on past performance.
