The best time to run Facebook Ads is not one universal hour. It depends on audience behavior, funnel stage, campaign objective, time zone, and when conversions actually happen.

Start with your own account data. Review performance by hour and day, then compare CPA, conversion rate, ROAS, and revenue—not just clicks or engagement. Industry benchmarks can guide testing: B2B campaigns often perform well during working hours, while e-commerce and lifestyle brands may see stronger results in the evening or on weekends.

Timing should also match the funnel. Awareness campaigns can benefit from lower-cost reach during quieter periods. Retargeting often works better during lunch breaks or evening browsing. Conversion campaigns should run when users have enough time and intent to complete the action.

Avoid restricting delivery too early. Narrow schedules can reduce the volume Meta needs to optimize, especially during the learning phase. Start broad, collect enough data, then remove consistently weak time windows.

Remember that Meta schedules ads using the ad account time zone. Global campaigns may need separate regional ad sets to reach users at the right local hours.

The goal is not to find a magic hour. It is to identify when profitable customer journeys begin and allocate more budget to those windows.
