Meta frequency controls: target frequency vs frequency cap, in Meta's words

Meta has two frequency controls, target frequency and frequency cap. Which goals, budgets and buying types get each, and where Meta's pages disagree.

Meta offers two frequency controls. Target frequency "aims to deliver a specific number of impressions per person per week", and in auction campaigns it needs a Reach or ThruPlay performance goal, a lifetime budget, no bid control and a campaign of 7 to 90 days. A frequency cap "limits the maximum number of times your ad is shown to each person" (another Meta page words it as an average), and Meta says it stays available for the three goals that exclude target frequency. You set either one at the campaign level, if Advantage+ campaign budget is on, or at the ad set level, if it is off, never both. Reservation campaigns get the same two controls, with target frequency as the default.

Another Meta page says auction campaigns get a frequency cap only. That claim does come from Meta, but it is out of step with the page that documents the controls.

What does "About frequency controls for auction" say?

Meta's article About frequency controls for auction is short. It names the two controls in one list:

Target frequency: Aims to deliver a specific number of impressions per person per week, helping you build frequency toward the same audience.

Frequency cap: Limits the maximum number of times your ad is shown to each person, helping you prioritize broad reach.

The difference is the direction. Target frequency pushes delivery toward a number, so more of your audience sees the ad that many times. A cap only stops delivery past a number, and Meta calls it "ideal when you don't have a specific frequency goal and want to prioritize broad reach". Meta's choosing your frequency controls page words the cap as an average instead: "the maximum number of times, on average, a person will be shown your ad within a set period of time."

Frequency itself is "the average number of times each Meta Account saw your ad", calculated as "impressions divided by reach", in the words of Meta's Frequency metric page. Both controls steer that average. None of Meta's frequency-control pages presents either one as a fix for tired creative; Meta's creative fatigue status is measured on cost per result, not frequency.

Target frequency vs frequency cap: when each one is available

In an auction campaign, Meta lists two conditions for target frequency:

Campaigns and ad sets that use Reach or ThruPlay as the performance goal, have lifetime budgets, and that don't have a bid control.

Campaigns that are between 7-90 days.

A notice at the top of the same page rules out three goals by name: "Target frequency is not currently available when using the ad recall lift, 2-second continuous video views, or post engagement performance goals. Frequency cap remains available for these goals."

The auction page doesn't list objectives. The goals it names are awareness and engagement goals; it says nothing about frequency controls on sales, leads, traffic or app promotion campaigns.

Campaign level or ad set level?

Either, depending on one switch. Meta's page:

Campaign level: Available with the auction buying type when you turn on Advantage+ campaign budget (also known as Campaign budget, or Budget with Advantage+ on). Campaign-level frequency controls apply across all ad sets within the campaign.

Ad set level: Available when Advantage+ is turned off. Your frequency control settings apply to individual ad sets.

Meta's example for the campaign level: with a cap of 2 impressions per 7 days, "a person will see no more than 2 impressions from the entire campaign during that period — even if they fall into the audience of multiple ad sets." And the two levels don't combine: "Campaign-level and ad set-level frequency controls can't be used at the same time."

So the level follows the budget. If you run Advantage+ campaign budget, the control sits on the campaign and covers overlapping ad sets. With ad set budgets, the settings "apply to individual ad sets", so each ad set has its own. Either way the control ends at the campaign: Meta's example counts impressions "from the entire campaign", not from your other campaigns.

Frequency controls in reservation campaigns

Reservation is Meta's other buying type (it was called reach and frequency until October 2023). Meta's About reservation page says it is for advertisers who want to "Reach an audience of more than 200,000 people", "Control how many times people see their ads" and book "up to six months in advance", at a fixed CPM.

Meta's frequency controls for reservation page makes target frequency the default:

Target frequency is a new frequency control and the default frequency control for reservation campaigns. Target frequency will be replacing increased average frequency as a frequency control.

It is "for campaigns that are 7 days or longer" and "best for campaigns between 2 to 4 weeks". Its example compares the two controls set to one impression every 7 days: the cap "may deliver a higher percentage of reach", while target frequency "may produce an average weekly frequency that's closer to one impression every 7 days". For a 14-day target frequency campaign, Meta's projected spread is "44% of people … to see your ad four times, 15% three and five times, 12% once and twice, and 3% six times". With a cap of 2 every 7 days over 14 days, "the average cumulative frequency is expected to be lower than the frequency cap you set", and more ads may be "delivered at 1 to 2 times".

Meta's choosing your frequency controls page adds the availability table for reservation:

ControlObjectivePerformance goalCampaign duration
Target frequencyAwareness, EngagementReach, ThruPlayMinimum 7 days
Frequency capAwareness, EngagementReach, ThruPlayNo minimum

Its illustration makes the delivery difference concrete: a cap of 2 per 5 days over five weeks gave "high delivery of ads in the beginning and at the end of the campaign", while target frequency at 1 per 7 days over six weeks gave "an even distribution of frequency". The same page says "Your frequency control choices impact the cost of your reservation campaign", and that after any change the system "will generate a new prediction before you proceed with booking."

Two Meta pages that contradict the frequency articles

Two of Meta's pages don't match the frequency-controls articles.

Auction and target frequency. Meta's Choose the right buying type for your brand campaign page compares the two buying types in a table. Its "Frequency controls" row reads "Target frequency (default), Frequency cap" for reservation and "Frequency cap" alone for auction. The auction article above says auction campaigns can use target frequency with a Reach or ThruPlay goal. The auction article is the one written about the controls, and it carries a notice about current availability, so it is the likelier of the two to be up to date. But the buying-type page is live, and it is a Meta page.

Awareness only, or engagement too? Meta's Set up a reservation campaign page says "Target frequency and frequency cap are supported in awareness campaign objective's reach and ThruPlay performance goals." The choosing-controls table lists Awareness and Engagement, and the same setup page says reservation supports "an engagement objective with the performance goal of maximizing ThruPlay views for video."

If a control is missing from your setup, check the goal, the budget type, the bid control and the campaign dates against the auction article's list before reading either line as a removal.

How to choose

  1. Start from the goal. If you want people to see the ad a set number of times a week (a launch, a story told over several ads), target frequency is built for it. If you want as many different people as possible and just don't want anyone flooded, use a cap.
  2. Check Meta's two conditions for target frequency in auction: a Reach or ThruPlay goal with a lifetime budget and no bid control, and a campaign of 7 to 90 days.
  3. Decide the level with your budget. Advantage+ campaign budget on means a campaign-level control that spans ad sets; off means one per ad set.
  4. Don't use a cap to fix fatigue. Meta's fatigue recommendations don't include one, and the frequency number can't see repetition across ads that use the same image.

Feature availability is per account, and Meta revises these pages without notice, so check the source before acting on any of it.

Terrads makes new image and video ads that differ in concept and layout, so a higher frequency target has more than one picture to spread across.
