A content scheduler for scheduling content publication is provided. The content scheduler may include instructions to generate a time window and a quota. For example, the instructions may cause a processor to generate a first time window for placing a first article of content. The instructions may also include a first quota indicating a first total number of impressions. The content scheduler may also include an analyzer configured to be run by the processor. The analyzer may be configured to determine when first and second articles of content should be scheduled to be published. The analyzer may be configured to determine a first average number of impressions per unit of time needed to deliver the total number of impressions required by the first quota. The analyzer may be configured to determine whether there is a period of overlapping time between the first and second articles of content.
