Ad Fatigue
Ad fatigue happens when the same people see your ad so often that they stop paying attention, so results drop and costs rise.
Example
An ad that brought cheap leads for three weeks starts costing twice as much per lead as frequency climbs.
How to read it
Rising frequency plus rising cost per result is the classic sign of fatigue.
Why it matters
Fresh creative keeps campaigns working. Spotting fatigue early saves budget.
Common mistakes
- Waiting until results collapse before making new ads.
- Changing the audience when the real problem is the creative.
- Pausing winning campaigns instead of adding new ads to them.
How to improve Ad fatigue
- Launch new creative on a regular schedule.
- Test new hooks and formats, not just new colours.
- Watch frequency and cost per result together.
- Add new ads to working campaigns instead of pausing them.
