Abstract: An analysis system may receive a request to determine a cause of underdelivery for an ad (“query content item”). Properties of the query content item can be processed through a matching model to determine properties of a bid request, thereby generating a bid request. The generated bid request also includes a request for the content server to return a report in response to the bid request regarding ad selection decisions. The bid request may be submitted to the content server, which causes the content server to define a set of candidate content items and select at least one of the candidate content items to submit bids on behalf of in response to the bid request. The content server also provides a report in regarding ad selection decisions. Thus, if the query content item is one of the ads that were not selected, the report may include factors contributing to the query content item not being selected.

Abstract: A computing device is configured to display content using a set of rules for individual content campaigns. The set of rules are provided with parameters determined from a simulated budget. Simulated bidding traffic is provided. Weighted bid traffic is generated based on evaluating the simulated bidding traffic with the set of rules. Qualified bid requests are provided from using the weighted bid traffic and updates to the parameters of the simulated budget. The qualified bid requests are applied to content servers to secure content slots for displaying content.
