Formula
Frequency = defined numerator / defined denominator over a consistent reporting period- Numerator
- The primary counted outcome or cost used in Frequency.
- Denominator
- The population, event count or time period used to normalize Frequency.
- Reporting window
- The date range used consistently across inputs.
Worked example
If 250,000 impressions reach 80,000 unique people, average frequency is 3.125. Frequency can be much higher for specific audience segments than the campaign average.
Healthy frequency depends on campaign goal, creative fatigue, purchase cycle and channel. Compare it with reach, CPM, CTR and creative fatigue signals.
How it works
Frequency gives teams a named way to govern spend, creative and conversion quality. In the Marketing Refs graph, it links definitions to adjacent metrics, workflows and operating choices instead of leaving the term as isolated vocabulary.
