Dayparting
Scheduling ad delivery to specific hours of the day.
Dayparting is the practice of restricting campaign delivery to specific hours / days when the target audience converts best. Native networks (Taboola, Outbrain) and DSPs all support hour-of-day and day-of-week scheduling. Most ROI comes from killing the worst-converting overnight hours rather than from finding magic windows; data takes 4+ weeks to be statistically meaningful.
Example
Insurance lead-gen campaign: pause all delivery 1am–6am US-Eastern (call-center is closed → leads go cold → advertiser scrubs payouts). CPL drops 24%.
