Embodiments are directed towards modifying when to publish content to a channel for distribution based on monitored actions associated with previously published content. A plurality of publishing slots may be determined from a plurality of time slots. Each publishing slot may indicate a time to publish content to the channel. Content may be published to the channel at each of the plurality of publishing slots. User actions associated with the published content may be monitored. The plurality of publishing slots may be ranked based on these monitored actions. At least one of the plurality of publishing slots may be modified to a different time slot based on the rankings of the publishing slots. The publication of content at a publishing slot may be delayed based on a success of other content published at a previous publishing slot being above a threshold.
