Systems and methods for providing an actionable object within a third-party content slot of an information resource of a content publisher. A processor receives an indication of interest in providing, for display, a creative within at least one third-party content slot of an information resource of a content publisher. The information resource includes third-party content slots available to be reserved to serve creatives. The processor identifies, on the information resource, at least one third-party content slot available to be reserved to serve one or more creatives. The processor inserts an actionable object within the identified third-party content slot, the actionable object configured to generate a request to provide an interface for reserving the identified third-party content slot to display the creative responsive to an action being taken on the actionable object. The processor renders the information resource including the inserted actionable object within the identified third-party content slot.
