Simulating bid requests for content underdelivery analysis

A computing system, comprising:

• at least one computing device processor;
• and
• a memory device including instructions that, when executed by the at least one computing device processor, cause the computing system to:
• determine properties of a bid request based at least in part on the properties of a content item;
• submit the bid request to a content server, the content server determining one or more factors that contributed to whether the content item is a selected content item or an unselected content item in response to the bid request;
• generate, based at least in part on the one or more factors, a recommendation for improving delivery of the content item;
• and
• adjust, based on the recommendation, at least one property of the content item.
