Catch ad fatiguebefore it costs you.
When the same people see the same ad too many times, CTR falls and CPMs climb, you pay more for less. Get your frequency and a clear read on whether you're in the safe zone or already burning money.

How much you can pour in before fatigue
Impressions ceiling

Spend to reach it
$4,320
A cold / prospecting audience of 120,000 can absorb about 360,000 impressions before fatigue sets in — roughly $4,320 at a $12 CPM. Past that, the fix is fresh creative or a bigger audience, not more spend on the same ad.
Sensitivity · the same frequency, judged by audience
Why context decides fatigue
| Audience | Ceiling | Verdict at your frequency |
|---|---|---|
| Cold / prospecting | 3 | Fatigue territory |
| Warm / engagers | 5 | Healthy frequency |
| Retargeting | 7 | Healthy frequency |
Your frequency of 3.3 is the same number for everyone — but it's healthy for a warm retargeting pool and fatiguing for cold prospects. Always judge frequency against who's seeing the ad.

Fresh creative beats fatigue. That's my whole game.
Frequency 3.3 vs a Cold / prospecting ceiling of 3 — fatigue territory.
Ad fatigue is a creative volume problem, and producing enough genuinely different concepts is exactly what I build. Send me your account and I'll show you how to keep frequency healthy and costs flat.
Plain English
Frequency is how often, fatigue is what it costs.
Ad frequency is the average number of times each person in your audience saw your ad, total impressions divided by unique reach. A frequency of 3 means the average person saw it three times.
A little repetition helps; too much triggers ad fatigue. As frequency climbs past your audience's tolerance, click through rate drops, cost per click and CPM rise, and negative feedback (hides, 'see fewer') increases. You end up paying more to reach the same people with an ad they're tired of.
Tolerance isn't fixed, it depends on the audience. Cold prospects fatigue fast, around a frequency of 2 to 3. Warm audiences handle 4 to 5. Retargeting audiences who already know you can run to 5 to 7. The fix is almost always fresh creative, not a smaller audience.
The formula
Frequency = Impressions ÷ Reach
400,000 impressions across 120,000 unique people = a frequency of 3.3. For a cold prospecting audience (tolerance ~3), that's already at the fatigue line. Time to refresh creative or widen the pool.
Where fatigue tends to start
Healthy weekly frequency varies by platform and audience temperature. Rough guides for when to watch for fatigue:
| Platform / placement | Healthy frequency |
|---|---|
| Meta prospecting | ~3.5 / week |
| Meta retargeting | 4–7 / week |
| TikTok | ~5 / week |
| Google Display | 1.5–3 / week |

Reading your frequency
Frequency past audience tolerance.
You're in fatigue territory. Ship fresh creative now, new hooks reset frequency far more effectively than shrinking the audience.
Rising frequency + falling CTR.
The classic fatigue signature. CPMs are about to climb. Rotate creative and consider expanding the audience to dilute frequency.
Cold audience above 2 to 3.
Strangers tire fast. Either broaden targeting to lower frequency or move them to a fresh concept before performance rolls over.
Retargeting above 7.
Even warm audiences burn out eventually. Cap frequency, refresh the offer, or exclude people who've seen it too many times.
Keep frequency healthy
01Refresh creative on a schedule
Rotate every 7 to 14 days depending on audience; new creative resets fatigue.
02Run multiple hooks per ad set
Four to six fresh angles keep frequency healthy 2 to 4× longer than a single creative.
03Broaden the audience
A bigger pool spreads impressions across more people, lowering frequency.
04Exclude over exposed users
Cap frequency or exclude people who've already seen the ad many times.
05Watch CTR and CPM together
Falling CTR with rising CPM is your early warning system for fatigue.
06Sequence the message
Show different ads to the same audience so repetition feels like a story, not a loop.

Ad frequency questions
Divide total impressions by unique reach. 400,000 impressions seen by 120,000 people is a frequency of about 3.3, the average person saw the ad just over three times.
