What is ad recall lift in Meta ads?
Ad recall lift estimates how many people would remember seeing your ad if asked within two days. Meta labels it estimated and in development, projects it with machine learning calibrated by polls, and says to compare it only across campaigns running at the same time. It is an estimate, not a count of people.
Ad recall lift rate = ad recall lift ÷ reach
Ad recall lift is Meta’s estimate of how many people would say they remember your ad if they were asked within two days. It appears for ads that use the ad recall lift performance goal inside the awareness objective. Meta labels it estimated and in development, so treat each figure as a model output, as checked on 2 Oct 2026, and compare it only with campaigns that ran at the same time.
What does ad recall lift measure?
Meta defines ad recall lift as the incremental number of people who would answer “yes” to the question “Do you recall seeing an ad from [brand] in the last few days?” The incremental number comes from asking an exposed group, who saw the ad, and a control group, who did not, the same question and taking the difference between the two.
Meta says it uses machine learning to project the result of a full ad recall survey from its own data for this approximate metric. It says it chooses people using more than a thousand signals, including their existing relationship with your Page, their likelihood of interacting with the ad and demographic characteristics. It calibrates its predictions by running thousands of polls a day on a random sample of campaigns.
Where do you find it in Ads Manager?
- Open Ads Manager.
- Go to Columns: Performance in the top right and choose Customize columns.
- Search for Ad recall lift and Cost per ad recall lift, and select both.
- Select Apply.
- Open the Columns menu again and choose Delivery to add reach and frequency beside them.
How are the rate and the cost defined?
| Metric | Meta’s definition |
|---|---|
| Ad recall lift (people) | The estimated number of people likely to remember your ads within two days |
| Ad recall lift rate | The estimated incremental number of people who recall your ad, divided by the number of people your ad reached, shown as a percentage |
| Cost per ad recall lift | The average cost per incremental person Meta estimates will recall seeing your ad if asked |
| Reach | The number of people who were served an impression |
A high rate can look good, but Meta warns that if the ad did not reach many people it is unlikely to create many recallers. An ad set that reaches many people creates more incremental recallers, so Meta’s optimisation favours it. An ad set that is not reaching people does not deliver.
Why does Meta say to compare only simultaneous campaigns?
Because the metric is labelled estimated and in development, Meta says it is continuously improving the calculation. Its advice is to compare ad recall lift only across campaigns running at the same time, and not across campaigns with different targeting or from different periods. Meta also says results measured with the old method, roughly before December 2017, should not be compared with newer campaigns.
How can you use it to compare creatives or audiences?
Meta’s guide gives two set-ups, both run simultaneously:
- Creatives: put each creative in its own ad set, target the same broad audience, and compare cost per ad recall lift for an indication of which creative may be more memorable.
- Audiences: use the same creative in two ad sets that target different audiences, and compare cost per ad recall lift for an indication of which audience found it more memorable.
Meta recommends a relatively wide audience for this goal, and says testing is the best way to find a good targeting strategy.
How is it different from a brand lift test?
Meta says a brand lift test is required for the most accurate measurement of ad recall. If your campaign does not meet the criteria for a full study, it describes ad recall lift as an affordable, accessible alternative. It also says eligibility depends on multiple factors and availability is not guaranteed. Third-party studies such as Nielsen Brand Effect may deliver different numbers. Meta says Nielsen Brand Effect studies are based on poll responses, while its metric is an estimate based on data and signals from the campaign, using poll responses for calibration.
FAQ
Is ad recall lift a count of people who remembered my ad?
No. Meta calls it an estimate. It is the estimated number of people likely to remember your ads within two days, projected from signals and calibrated with polls. Meta says it may be imprecise, and that it is best to use a brand lift study to measure it accurately.
Why is my ad recall lift rate high when few people saw the ad?
The rate is a percentage of the people reached, so it does not tell you how many people that is. Meta says a high percentage might look good, but an ad that did not reach many people is unlikely to create many recallers. Check reach beside the rate.
Can I compare this month’s ad recall lift with last month’s?
Meta advises against it. Because the metric is in development and varies by audience, it recommends comparing only campaigns running at the same time with the same targeting. To compare creatives or audiences, run them side by side and look at cost per ad recall lift.
