This document describes a system and method in which signals from a third-party content provider are used to help select content items in the content item campaign of the third-party content provider. The selected content items are then presented to a resource. The signals may be used to help select between content items for which there are known metrics and content items for which there are no metrics. The signals indicate trends or preferences that may indicate that one content item or type of content item is a better choice compared to other content items.
