Abstract: Herein are techniques for content delivery pacing based on multidimensional forecasting. In an embodiment, a computer receives, for a content delivery campaign, targeting criteria and a resource usage limit of a limited resource. Entities that match the targeting criteria are identified for which content of the delivery campaign may have increased relevance. For each matching entity, a forecast of requests that might originate from the entity during each of a series of time intervals is generated to predict opportunities to deliver the content of the campaign. The forecasts of the matching entities can be combined to generate a combined forecast of requests for the targeting criteria. The computer generates, based on the combined forecast and the resource usage limit for the content delivery campaign, and stores for future use a fulfilment schedule that specifies amounts of requests to fulfill during the series of time intervals.
