Summary
Ad recall is the Brand Lift metric that directly measures whether people remember a campaign. It compares survey responses from an exposed group against a randomised control group, so the lift you see is attributable to your ads. Purchase intent, favourability and frequency measure other things entirely.

When a brand wants to know whether people remember seeing their campaign, the Ad recall metric in a Brand Lift study measures it directly by comparing recall between an exposed group and a randomised control group.
- Purchase intent
- Frequency
- Ad recall
- Favorability
The correct answer is: Ad recall
Key Takeaways
- – Ad recall is the Brand Lift metric that directly measures whether people remember seeing your campaign.
- – Brand Lift compares a randomised exposed group against a control group and reports lifted users, lift percentage and cost per lifted user.
- – Ad recall sits at the top of the funnel, so it usually reaches statistical significance faster and on a smaller budget than consideration or purchase intent.
- – Frequency is a delivery metric from your campaign report, not a Brand Lift survey metric, so a high frequency does not prove people remember the ad.
How does Google actually calculate ad recall lift?
Google splits your eligible audience into an exposed group and a randomised control group that is held back from your ad. Both groups get a survey question asking whether they remember seeing an ad for your brand in the last two days. The difference in positive responses between the two groups is the lift, and Google reports it as absolute lift, relative lift and cost per lifted user.
Where do I set up a Brand Lift study in Google Ads?
Go to Tools in the left navigation, then Measurement, then Brand Lift. You create the study, choose the metric such as Ad recall, add the campaigns you want included, and confirm the survey questions and brand name. Studies need a minimum spend commitment over the measurement window, so check the budget requirement before you launch.
Is ad recall the same as brand awareness in a Brand Lift study?
No, and this is a common mix up. Ad recall asks whether the person remembers seeing your advertisement. Brand awareness asks whether they know the brand exists at all. A user can be aware of a brand for years and still fail an ad recall question, which is exactly why the two are reported separately.
Why might a Brand Lift study return no measurable ad recall lift?
The usual reasons are insufficient budget, too short a measurement window, or too few survey responses to reach statistical significance. Very broad targeting also dilutes results because the exposed group gets spread thin. Fix it by concentrating spend, extending the study period and keeping the campaign creative consistent while the study is running.
