Frequency
Frequency is the average number of times each person in your audience saw your ad, calculated as impressions divided by reach.
Some repetition aids recall, but too much causes fatigue and wasted spend. For example, a frequency climbing past comfortable levels for the same viewers often signals it is time to refresh creative or widen the audience. Monitoring it keeps campaigns from annoying their audience.
Frequency is a curve, not a number: too little and the message never lands, too much and cost per result climbs while sentiment falls. The workable practice is watching frequency against results decay weekly, when cost per outcome starts rising as frequency climbs, the audience is saturating, and the fixes are ordered: refresh creative first, widen or rotate audiences second, cap frequency directly only where the platform allows it cleanly. Small audiences saturate fast, which is why remarketing pools need caps most, the people most worth reaching are the easiest to exhaust.
Example
An awareness campaign runs four weeks. Week one, frequency 2.1 and cost per result stable. Week four, frequency 9.4: the same people seeing the same creative daily, results per baht down 60%, and hide-ad feedback climbing. Refreshing creative and widening the audience resets it to 3. The metric flagged the fatigue two weeks before anyone would have noticed in revenue.
Frequently asked questions
- What is the ideal ad frequency?
- Enough repetitions to be remembered, stopping before waste: awareness tends to build to a handful of exposures, remarketing tolerates more within short windows. The signal to watch is cost per result rising as frequency climbs, that is saturation announcing itself.
- How do I fix high frequency?
- Refresh creative first, fatigue is often message-level, then widen or rotate audiences, and cap frequency directly where the objective supports it. Small retargeting pools saturate fastest, so exclusions and time-windows matter most there.
