What frequency measures

Meta defines frequency as The average number of times each Meta Account saw your ad. It is calculated as impressions divided by reach, so it comes from two other metrics:

• Reach is the number of Meta Accounts that saw your ads at least once.
• Impressions is the number of times your ads were on screen. Meta counts an ad that is on screen for someone twice in a day as two impressions, but scrolling away and straight back to the same ad counts once.

So 10,000 impressions across 4,000 accounts is a frequency of 2.5. Because it is an average, some people will have seen the ad once and others many more times. Meta labels frequency an estimated metric and says it is calculated using sampled data, and reach is estimated too. Treat it as a guide to exposure, not an exact count of people.

You find it in Ads Manager under Columns: Delivery, next to Reach (our Ads Manager reporting guide covers columns and presets). Meta's own page on awareness results points there, and calls reach and frequency important measures of the success of any brand campaign.

What a normal frequency looks like

Meta does not give one right number. Its frequency page says it may average 1 to 2 per ad set or may be much higher, depending on your budget, audience size and schedule. That gives three levers. A bigger budget on the same audience pushes frequency up. A smaller audience reaches its limit sooner, so the same people see the ad again. A longer schedule adds more chances to see it.

Repetition is not bad in itself. Meta says frequency helps to build awareness and recall by showing a message to the same audience more than once, and its reservation page says a high-frequency strategy may suit new brands with a low market share or shorter campaigns. The question is whether results hold up as the number climbs, which is covered below.

Where you can control frequency

Meta has two buying types, and they handle frequency differently. Meta's buying-type comparison sets them side by side for awareness and engagement campaigns:

	Auction	Reservation
Frequency controls	Frequency cap	Target frequency (default) or frequency cap
Performance goals	Reach (default), impressions, ad recall lift, ThruPlay, 2-second continuous video view	Reach (default), ad recall lift, ThruPlay
Price	Changes in the auction	Fixed CPM once booked, unless paused
Prediction	Daily reach only	Reach, frequency distribution, spend per day and placements
Placements	Facebook, Instagram, Messenger and Audience Network	Facebook and Instagram

Meta's pages describe frequency controls only for the awareness and engagement objectives. For sales, leads, traffic or app campaigns, the tools Meta points to are the ones further down: watching the frequency column, refreshing creative, widening the audience and automated rules. The old reach objective has been folded into the awareness objective, where you can choose to maximise reach or impressions.

Reservation: target frequency vs frequency cap

Reservation (called reach and frequency until October 2023) lets you book awareness and engagement campaigns in advance at a fixed CPM, with a prediction of reach and frequency. Meta says it is for advertisers who want to reach more than 200,000 people, want predictable reach, want to control how often people see their ads and want to plan ahead. You can book up to six months in advance. Delivery is predicted, not guaranteed, and Meta charges only for ads delivered.

Inside a reservation campaign you pick one of two controls. Both are supported for the reach and ThruPlay performance goals in the awareness and engagement objectives.

• Target frequency (the default) is the average number of times per week you want people to see your ads. The campaign must run at least 7 days, and Meta says it works best for campaigns of 2 to 4 weeks. It spreads delivery evenly: in Meta's example, a target of 1 impression every 7 days over six weeks produces an even frequency across the campaign.
• Frequency cap is the maximum number of times you want people to see your ads, with no minimum duration. The glossary gives the default as 2 impressions every 7 days. Meta calls it ideal when you want to avoid reaching the same people too many times and put broad reach first. In Meta's five-week example with a cap of 2 every 5 days, delivery was heavy at the start and the end of the campaign.

Two practical points from Meta's pages. First, with a cap of 2 every 7 days on a 14-day campaign, the average frequency is expected to land below the cap, with most people seeing the ad once or twice. Second, raising the average frequency means fewer people reached, because the same budget goes on showing the ads again to the same people. Every change to the frequency settings creates a new prediction and can change the cost, so compare a few settings in the reservation estimates before you book.

Signs that frequency is too high

Meta's advice on the frequency page is to watch it together with results and ad relevance diagnostics: If performance begins to drop as your frequency numbers rise, your target audience may be experiencing ad fatigue, and it may be time to change the creative or the targeting. In practice, look for these signs:

• Creative limited or Creative fatigue in the Delivery column. Meta looks at recent exposures of the same image or video, including in other campaigns from your Page, and at cost per result. If cost per result is higher than your past ads but less than twice as much, the status is Creative limited. At twice as much or more, it is Creative fatigue. Meta says this feature is only available for ad sets with one creative (with some exceptions), and it may also warn you before launch if fatigue is likely in the first 7 days.
• Audience saturation. Meta's delivery troubleshooting page describes it as a high share of your audience having seen your ads without acting, and suggests a larger audience.
• Falling relevance diagnostics. Quality, engagement rate and conversion rate rankings compare your ad with ads competing for the same audience. They need at least 500 impressions and are meant for diagnosing ads that are not meeting their goal.

Meta's fixes for creative fatigue are to create another ad with a materially different image or video, to expand the audience, or, for traffic and sales campaigns with a website destination, to try Advantage+ creative. Meta notes that keeping the original ad running rather than pausing it may maximise results.

Pausing ad sets automatically

Outside reservation there is no hard cap, but you can stop an ad set when frequency passes a number you choose. Meta's example uses an automated rule:

1. In Ads Manager, open Ad sets, click More, and under Automated rules choose Create a new rule.
2. Select Custom rule, then Next, and give the rule a name.
3. Under Apply rule to, select the ad sets. Under Action, choose Turn off ad sets.
4. In Conditions, set Frequency to greater than 2 (or your own number).

The number 2 is Meta's example, not a recommendation. A rule like this stops delivery; it does not fix the cause. If the ad set should keep running, a new creative or a larger audience is usually the better answer. Google Ads has a similar tool, covered in our automated rules guide.

How we watch frequency

This part is our own practice, not Meta's guidance:

• We add Reach and Frequency to the column set we use for every account, so frequency is visible next to cost per result instead of in a separate view.
• We read frequency for the same date range as the results, because a lifetime number hides when the change started.
• For small local audiences we plan creative in sets from the start, so a fresh ad is ready when Creative limited appears.
• We use reservation only when a client runs a brand campaign big enough to meet Meta's audience size, and use auction campaigns for everything else.

Frequently asked questions

How is frequency calculated in Meta Ads Manager?

Frequency is impressions divided by reach: the average number of times each Meta Account saw your ad. Meta labels it an estimated metric based on sampled data.

Can I set a frequency cap on a Meta sales or leads campaign?

Meta's frequency controls are listed for awareness and engagement campaigns. For other objectives you watch frequency and manage it through audience size, budget, creative or an automated rule that turns off an ad set above a set frequency.

What is the default frequency cap in Meta reservation campaigns?

Meta's glossary gives the default frequency cap as 2 impressions every 7 days. Target frequency is now the default control in reservation campaigns, with a minimum campaign length of 7 days.

Why is my average frequency lower than my frequency cap?

A cap is a maximum per person, while frequency is an average across everyone reached. Meta says that with a cap of 2 every 7 days on a 14-day campaign, the average is expected to be lower than the cap.

What does Creative fatigue mean in the Delivery column?

Your audience has seen the same image or video too many times and cost per result is at least twice that of your past ads. A smaller rise shows as Creative limited.
