Is your Facebook ad frequency too high?
Frequency is impressions divided by reach, and on its own it tells you almost nothing. The useful question is how much of your audience is left. Put both numbers in below and find out. Nothing you type ever leaves your browser.
Your numbers
Where you are
These bands are rules of thumb, not measurements. Meta publishes no fatigue threshold, and the right frequency depends on your audience size, your buying cycle, and your creative. Use them to decide what to look at next, never as a rule to act on.

What this tool does
Every frequency tool on the internet will tell you that 3.0 is the danger line. None of them will tell you where that number came from, because it did not come from anywhere. Meta publishes no threshold. There is no study that generalises across a jewellery retargeting pool in December and a cold prospecting campaign in its first week, and those two things are not the same problem wearing different clothes.
Frequency is not a disease. It is a symptom, and usually a symptom of one thing: you have run out of people. When your audience is small and your budget is not, Meta has nowhere to put your impressions except in front of the same people again. The frequency climbing is the platform telling you the pool is drying up.
So the number this page leads with is not frequency, it is saturation: what share of the audience you targeted have actually seen this. That is arithmetic rather than folklore, and it explains the frequency instead of just measuring it. Reach 8 percent of your pool at frequency 3 and you have a targeting problem. Reach 80 percent of it and you simply need more people.
It is free, there is no signup, and the whole thing runs in your browser.
How to read your frequency properly
The number itself takes two seconds. Knowing what to do about it is the part worth having.
- 1Take reach and impressions from the same reportSame campaign, same date range. Ads Manager reports both by default. Mixing a lifetime reach with a seven day impression count is the fastest way to a wrong answer that looks fine.
- 2Add your audience sizeIt is optional here and it is the most useful thing you can type. Frequency without it is a number with no context. With it, you can see whether the frequency is because the ad is tired or because the pool is empty.
- 3Read saturation before frequencyHigh frequency with low saturation means Meta is showing your ad to the same slice of a big audience, which is a delivery or targeting question. High frequency with high saturation means you have simply used the audience up. Different problems, opposite fixes.
- 4Check your cost per result trend, not the frequencyFatigue shows up as your cost per result climbing while frequency climbs. If frequency is 4 and your cost per result is flat, nothing is wrong, whatever a band on some website says.
- 5Change one thingWiden the audience, refresh the creative, or lower the budget. Doing all three at once means you learn nothing about which one was the problem.
Why nobody can tell you a safe frequency
If you searched this, you have seen a confident 3.0 in a dozen articles. Here is why it is not a real number.
- 1Meta does not publish oneThere is no official threshold. The 3.0 that everyone repeats traces back to old media research about television, not to anything Meta has ever said about its own auction.
- 2Prospecting and retargeting are not comparableA cold audience at 4 is a warning. A warm retargeting pool at 8 in the run up to Christmas is a campaign working exactly as designed. One number cannot cover both, which is why the picker above changes the bands.
- 3It depends on your buying cycleSomeone buying a $9 phone case and someone buying a $4,000 sofa need very different amounts of exposure. Frequency that is fatigue for one is barely consideration for the other.
- 4So use it to ask a questionThe honest use of frequency is as a prompt to look at saturation and cost per result. It is never the answer. Anyone giving you a threshold to act on is guessing with confidence.
What frequency tells you, and what it does not
It is one division. It is genuinely useful in context and actively misleading without it.
What this tells you
- How much of the pool is goneSaturation is the number that actually explains a rising frequency, and almost no frequency tool bothers to ask for it.
- Whether the audience is too smallHigh frequency and high saturation is not a creative problem. It is a maths problem, and no new ad fixes it.
- Whether your numbers are wrongReach above impressions is impossible, and it catches the most common paste error: swapping the boxes or mixing date ranges.
- A sense of scale, per campaign typeProspecting and retargeting get different bands, because treating them the same is how people kill a working retargeting campaign.
What it cannot tell you
- Whether your ad is actually tiredThis is the big one. Fatigue is a cost per result trend over time, not a number on one day. Frequency correlates with it and is not it.
- Any real thresholdThere isn't one. Meta publishes nothing, the famous 3.0 is folklore from television research, and the bands here are conversation starters.
- Who saw it more than the averageFrequency is a mean. Some people saw it once and someone saw it forty times, and the average hides both.
- Your creativeA great ad survives a high frequency and a bad one was never going to work at 1.2. The number says nothing about the thing itself.
- SeasonalityEveryone's frequency rises in Q4 because everyone's audience is being fought over. That is the auction, not your campaign.
- What the ad looks like by nowThe fourth time someone sees your ad, they may also be seeing four days of comments underneath it. Frequency counts the impressions and has no idea what is attached to them.
Frequency vs what is under the ad
Frequency measures how often people see your ad. It has nothing to say about what they see when they do. Here is the split.
| This calculator | Sweep Inbox | |
|---|---|---|
| Price | Free, no signup | Paid, with a 7 day free trial |
| What it measures | How many times people saw the ad | What was underneath it when they did |
| The fourth impression | Counted | Cleaned up, so it does not come with a week of scam replies attached |
| What it can act on | Nothing. It is a division | Hides the comment within seconds |
| When it runs | When you open it | Around the clock |
Questions people actually ask
- Impressions divided by reach, for the same campaign and the same date range. If your ad served 120,000 impressions to 40,000 people, your frequency is 3.0, meaning the average person saw it three times. Both numbers are in Ads Manager by default.
