Quick answer: Frequency is impressions divided by reach. Impressions add up across campaigns. Reach does not, because one person reached by two campaigns is counted once in the account. So account frequency can sit above every campaign's frequency. The account number is closest to what your customer actually sees.
Why the account number is higher
Here is an illustrative account (about ₹6 lakh spend, ratios modelled on a real account we audited). Every campaign looks comfortable. The account does not.
| Level | Frequency |
|---|---|
| Campaign A | 2.7 |
| Campaign B | 2.4 |
| Campaign C | 2.5 |
| Campaign D | 1.8 |
| Account | 3.0 |
Same impressions on top, smaller reach underneath. If nobody overlapped, the account would show about 2.6. The gap between 2.6 and 3.0 is overlap showing up in frequency. To measure the overlap directly, see account reach vs campaign reach.
What it costs you
CPM is the price of 1,000 impressions, not 1,000 people. The price of reaching 1,000 different accounts is CPM times frequency.
| Measure | Value |
|---|---|
| CPM | ~₹210 |
| Cost per 1,000 accounts reached (CPM x 3.0) | ~₹640 |
| Same figure using summed campaign reach | ~₹545 |
Using summed reach understates the real cost of reaching a unique person by about 15%.
Always read frequency with a date window
Frequency only rises as the window gets longer. 3.0 over a month is mild. 3.0 in one week is heavy. Use the same window every time. For fatigue, use 7 days.
On cold audiences we start watching CTR and CPM closely once weekly frequency passes about 3 to 4. It is a trigger to look, not a rule. See creative fatigue signs.
Which frequency to track
| Type | What it tells you |
|---|---|
| Campaign frequency | Is one campaign wearing out its own audience |
| Account frequency | What a person sees across everything you run |
| Cold vs warm frequency | Retargeting pools are small, so frequency runs higher. Judge warm audiences by cost per purchase trend |

Likely causes, and the fix for each:
| Cause | Fix |
|---|---|
| Several cold campaigns hitting the same people | Consider merging campaigns with similar targeting if CPM is rising week on week and CTR is dropping. If both are stable, hold off and decide once the data supports it |
| Retargeting stacked on prospecting | Exclude purchasers and cap retargeting spend |
| One campaign on a small audience | Widen the audience |
| CTR falling as frequency rises | Rotate in a genuinely new concept |
Diagnose in order. First check for overlap. Then check CTR and CPM trend against frequency. If fresh creative does not help, the audience may be the limit. See creative fatigue vs audience fatigue.
Common mistakes
| Mistake | Why it matters |
|---|---|
| Reading frequency with no date range | The number cannot be judged |
| One threshold for every account | Fine for a high-ticket product, heavy for a low-priced one |
| Only checking campaign frequency | Each can look healthy while the customer sees you constantly |
| Calling fatigue from frequency alone | Check CTR and CPM first |
FAQ
What is a good frequency on Meta ads? There is no single number. On cold audiences, start watching closely at about 3 to 4 per week. Warm audiences run higher, so judge them by cost per purchase.
Why is account frequency higher than every campaign's frequency? Impressions add across campaigns, reach does not. Shared people count once in the account, which lifts the average.
Does high frequency always hurt performance? No. It hurts when extra impressions land on people who have already decided. If CTR, CPM and cost per purchase hold, it is fine.
Can I cap frequency on sales campaigns? Direct caps are limited on auction campaigns. Use audience size, budget and creative rotation instead.
Where do I find account frequency? In Ads Manager, read the totals row at the bottom with all campaigns in view and your date range set.
The takeaway
Read frequency at account level, always with a date window, and compare it with your campaigns. If the account runs higher than every campaign, you have overlap. Convert it to cost per 1,000 accounts reached to see what it costs, then merge, exclude or refresh creative.
