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.

Key takeaways

  • Use Frequency when the decision depends on paid acquisition economics and measurable channel performance.
  • Pair Frequency with related concepts before changing strategy, budget or execution.

Where it is used

  • Forecasting
  • Budget allocation
  • Performance diagnosis

Used by Marketing teams · Growth teams · Students

Examples

  • A growth team reviews Frequency by cohort so acquisition, conversion and retention decisions use the same reporting window.
  • A channel owner compares Frequency against related metrics before changing budget, creative or funnel priorities.

Common mistakes

  • Comparing Frequency across channels without matching the reporting window.
  • Optimizing Frequency alone without checking downstream quality or customer value.
