What is frequency?

FormulaFrequency = impressions ÷ reach (unique people)

As frequency rises, the same people see the same ad again and again. Beyond a certain point interest falls and costs rise.

In 14ads

• The frequency reported by the platform is used; if it does not arrive, it is calculated as impressions ÷ reach. If neither is available, no value is made up; it stays empty.
• When combining days, an impression-weighted average is used, not a simple average.
