Scheduling ads to run during specific hours of the day or days of the week.
Dayparting (also called ad scheduling) is the practice of running ads only during specific times when your audience is most likely to convert. Instead of running 24/7, you concentrate budget during peak performance windows.
Not all hours perform equally. A B2B advertiser may see most conversions during business hours (9am-5pm weekdays), while an e-commerce brand may peak during evenings and weekends. Dayparting focuses spend where it works best.
