What Is Brand Lift? Meaning, Measurement Methods, and Examples
Shusaku Yosa

When it comes to the effectiveness of ads and campaigns, results tend to be measured by “behavior” such as clicks and purchases. Yet how people’s awareness and impression of a brand changed after being exposed to an ad is also an important outcome. The metric that captures this is “brand lift.” This article organizes the meaning of brand lift, then explains representative measurement methods, points to watch when measuring, and use cases—all in a way that is easy for beginners to understand.
What Is Brand Lift?
Brand lift is a metric that expresses how much awareness, attitude, purchase intent, and the like toward a brand improved (lifted) as a result of exposure to an ad or campaign. It compares the awareness of “people who saw the ad” with “people who did not,” and uses that difference to visualize the effect on the brand.
Its characteristic is the ability to measure changes in attitude and awareness—“how much more favorably the brand came to be received”—which are hard to capture with direct behavioral metrics like clicks or conversions.
The Main Metrics Brand Lift Measures
Brand lift mainly measures changes in items such as the following.
- Awareness: How much the number of people who know the brand or product increased.
- Ad recall: Whether people remember having seen the ad.
- Favorability and brand image: Whether people came to have a better impression of the brand.
- Purchase intent (consideration/intent): Whether the feeling of “wanting to buy or use it” grew stronger.
Why Brand Lift Matters
The significance of measuring brand lift includes the following.
- Captures effects invisible to behavioral metrics: Even if it does not immediately lead to a purchase, gains in awareness and favorability become the foundation for future buying.
- Visualizes the results of branding ads: You can explain, in numbers, the value of ads that are not aimed at direct conversions.
- Connects to improvement: By grasping which creative or media drove the attitude change, you can apply it to your next initiative.
- Useful for explaining to management and stakeholders: You can share, with objective data, “how the ad affected the brand.”
How to Measure Brand Lift
Brand lift is measured by comparing “the group exposed to the ad” with “the group not exposed.” Let’s look at the representative methods.
Brand Lift Survey
The most common approach is measurement by survey. You pose the same questions to a group exposed to the ad (the test group) and a group not exposed (the control group), and compare the differences in answers on awareness, favorability, purchase intent, and so on. That difference is regarded as the “lift” created by the ad.
Ad platforms such as YouTube and Meta provide brand lift measurement features that use this mechanism, letting you run surveys in tandem with delivery.
Search Lift
A method that looks at how much searches for the brand or product name increased as a result of ad exposure. Rather than relying on surveys, it infers rising interest from the actual change in search behavior.
The Idea of Test and Control Groups
In either method, the key is to appropriately compare “people who saw the ad” with “people who did not.” By aligning the conditions of both groups as closely as possible and then looking at the difference, you suppress the influence of factors other than the ad and get closer to the pure ad effect. The design of this comparison greatly affects the accuracy of measurement.
Points and Cautions When Measuring
- Decide the purpose and metrics first: Clarify whether you want to raise awareness or lift purchase intent, and narrow down the metrics you should measure.
- Design the comparison carefully: Align the conditions of the test and control groups so you can compare them fairly.
- Secure a sufficient sample size: With too few respondents, you cannot judge whether a difference is mere chance. Secure a reliable scale.
- Align the timing: Survey at the same time—during or right after the campaign—to suppress discrepancies from external factors.
- Look at it alongside behavioral metrics: Evaluate not only attitude change but also subsequent behavior (searches, visits, purchases).
Brand Lift Use Cases (by Pattern)
Brand lift is used in various ways depending on the campaign’s purpose. Here are some representative patterns.
Raising Awareness for a New Product or Brand
A pattern where, at the launch of a not-yet-known product or brand, you deliver video ads and the like and measure how much awareness and ad recall rose. You confirm “how many people came to know it” as the result.
Comparing Creatives and Media
A pattern where you compare multiple ad creatives or delivery media and verify which most lifted favorability or purchase intent. Based on the results, you shift budget toward the higher-performing patterns.
Proving the Effect of Branding Initiatives
A pattern where, for branding ads not aimed at direct purchases, you show gains in awareness, favorability, and recall in numbers to explain the initiative’s value inside and outside the company. It visualizes contributions that sales alone cannot measure.
Summary
Brand lift is a metric that expresses how much awareness, favorability, purchase intent, and the like improved as a result of exposure to an ad or campaign. Its characteristic is the ability to visualize “changes in awareness and attitude”—which are hard to see with behavioral metrics like clicks or purchases—by comparing the exposed and non-exposed groups. Measurement uses brand lift surveys and search lift, and a design that appropriately compares the test and control groups determines the accuracy. Start by defining, for your own ads, “what awareness you want to change, and by how much,” and measure effectiveness with metrics that match your purpose.
