Clicks don’t tell you if your video campaign worked. Measuring brand lift reveals how your creative actually changes perception and intent, the stuff that matters. You need a systematic approach inside Google Ads, using the specific tools and methods they provide, to actually quantify what your video ads are doing.

Key Takeaways

  • Find Brand Lift in Google Ads under “Tools and Settings” > “Measurement” to get started.
  • Use a minimum of 1,000 users for both your target audience and control group to get statistically valid data.
  • Pick metrics like ad recall or consideration that actually match your campaign’s main goal.
  • Expect to run your campaign for at least 7 days and hit 2 million impressions before you see any reliable brand lift data.
  • In the Brand Lift dashboard, analyze the reports by comparing the exposed and control groups for statistically significant differences.

Accessing the Brand Lift Measurement Tool

You have to start measuring your video campaign’s impact inside the Google Ads interface. Google has built-in tools to measure these exact shifts in consumer perception, and to get started on a brand lift study, you just need to find the right section in your account.

  1. Navigate to Tools and Settings

    From your main Google Ads dashboard, you’re looking for the “Tools and Settings” icon, it’s the wrench in the top right. Clicking it opens a dropdown menu that lists all the operational and measurement tools available to you.

  2. Select Brand Lift Under Measurement

    In the “Tools and Settings” menu, find the “Measurement” column and click on “Brand Lift.” This brings you to the Brand Lift Studies overview page, which is basically the dashboard for all your past and current studies. If you don’t see this option, don’t panic. It’s not always on by default for every account, so you may need to check your permissions or contact Google support to get it activated.

Setting Up a New Brand Lift Study

Once you’re on the Brand Lift Studies overview page, you’ll see it’s a guided process to create a new study. Getting the setup right from the start is absolutely essential because accurate setup is what makes your data useful later on. It all comes down to linking the right campaigns and defining the parameters for what you want to measure.

  1. Create a New Study

    Find and click the big blue “+ New Study” button on the Brand Lift Studies page. This launches a setup wizard that will guide you through everything. Make sure you name your study something descriptive so you can find it later, I usually include the campaign name and the date.

  2. Link Your Video Campaign

    First thing the wizard will ask is for you to link the specific video campaign you want to measure. You can pick one or more from your account, but they have to be eligible, which usually means they’re running on YouTube and its partner network using brand-friendly formats like skippable/non-skippable in-stream ads, bumper ads, or outstream ads. Don’t even try to run a brand lift study on a campaign that’s only focused on conversions or app installs. It’s the wrong tool for the job.

  3. Define Your Target Metrics

    Now you have to decide what parts of brand lift you’re actually trying to measure. Google has a few standard options:

    • Ad Recall: Measures whether users remember seeing your ad.
    • Brand Awareness: Gauges familiarity with your brand.
    • Consideration: Indicates whether users would consider your product or service.
    • Favorability: Reflects positive sentiment towards your brand.
    • Purchase Intent: Quantifies the likelihood of users purchasing your product.

    You get to pick up to three metrics for each study. It’s smart to pick the ones that line up with what the campaign is supposed to be doing. For instance, if you’re launching something new, brand awareness and consideration are probably your best bets, whereas for a retargeting campaign, purchase intent makes a lot more sense.

  4. Set Up Survey Questions

    Google will then automatically generate the survey questions that get shown to your audience (and the control group) based on the metrics you just picked. For example, selecting “Ad Recall” might create a question like, “Which of these brands have you seen advertised online recently?” with your brand listed among competitors. You get to review these questions and can sometimes make small edits, but you can’t really change them much because Google needs to keep the survey methodology consistent platform-wide for the results to be valid. Just make sure they make sense and aren’t confusing.

Understanding Control and Exposed Groups

Any reliable measurement has to be based on a comparison. For brand lift studies, this is done by creating control and exposed groups. This method is absolutely essential for accurate attribution. Without it, you’re just guessing.

  1. Automatic Group Allocation

    As soon as you set up the study, Google automatically splits your target audience into two buckets: the exposed group (they see your video ads) and the control group (they don’t). Since the control group is pulled from the exact same audience, this setup is what lets you isolate your advertising’s actual impact.

  2. Ensuring Statistical Significance

    For your results to be statistically valid, both groups have to be large enough. Google’s recommendation is a bare minimum of 1,000 users per group before you can expect to see reliable data, though honestly, bigger sample sizes will always give you stronger insights. You absolutely have to budget enough to get the impressions needed to build these sample sizes, otherwise, the whole study is a waste. A Nielsen study (nielsen.com/insights/2023/the-power-of-brand-lift-studies-quantifying-marketing-effectiveness) really drives this home, pointing out that this control group method is what makes it genuine impact measurement instead of just looking at correlation.

  3. Pro Tip: Monitor Group Sizes

    As the campaign is running, keep an eye on how impressions are being delivered to each group. If the groups become unbalanced, with one being much smaller or not getting enough impressions, it can completely skew your results. You might have to jump in and tweak your campaign’s budget or targeting to get a more balanced delivery.

Running Your Video Campaign for Brand Lift

Running the actual video campaign isn’t that different from what you’re used to, but there are some specific things to keep in mind for brand lift measurement. You have to be patient. The data for these studies builds up over time.

  1. Minimum Campaign Duration and Impressions

    Google has some hard minimums here: your campaign has to run for at least seven days and generate a minimum of 2 million impressions across YouTube and its partners. This is the floor required for the survey system to get enough exposure to actually collect responses from both your exposed and control groups. If you try to run a campaign with a budget that can’t deliver that kind of volume, you will get zero brand lift data. It’s that simple.

  2. Budget Allocation for Surveys

    Be aware that Google automatically reallocates a small slice of your campaign budget to serve the brand lift surveys. This isn’t an extra charge. It’s just a portion of your existing budget being used for measurement. This budget allocation is absolutely necessary for the study to work because without it, you have no way to collect user responses.

  3. Common Mistake: Premature Optimization

    Here’s a common mistake I see all the time: people start tweaking the campaign too soon. You absolutely cannot make big changes to your video creative, your targeting, or your bidding strategy during the first week of a brand lift study. Why? Because every change you make muddies the water, making it impossible to say what actually caused the results. You have to let the campaign run for at least those first seven days without messing with it.

Analyzing Brand Lift Report Data

After your campaign has run long enough and hit the impression minimums, the data will start to appear in the Brand Lift dashboard. This is where you get to find out if your campaign actually worked.

  1. Accessing the Brand Lift Dashboard

    Go back to where you started: “Tools and Settings,” then “Measurement,” and click on “Brand Lift.” From there, you just select the study you want to look at. The dashboard shows all your results, usually with easy-to-read charts and the statistical breakdown.

  2. Interpreting Key Metrics

    The main number you care about is called “Brand Lift.” It’s simply the difference in how the exposed group responded compared to the control group for whatever metrics you chose. For example, if 30% of your exposed group recalled the ad and only 20% of the control group did, that’s a 10 percentage point lift in ad recall. The dashboard will also show you the statistical significance, usually with a confidence interval which is just a way of confirming that the difference you’re seeing isn’t a random fluke.

  3. Segmenting Your Data

    Inside the Brand Lift dashboard, you can break down your results by dimensions like demographics, device type, or even the ad groups in your campaign. This segmentation is how you find out which audiences actually responded best to your video creative. For example, you might discover that your ad recall was through the roof for users aged 25-34 on mobile, which is a powerful signal that your message really connected with that specific group.

  4. Expected Outcomes: Positive Lift vs. No Lift

    A good brand-building video campaign should produce a positive and statistically significant brand lift in one or more of the metrics you chose. That’s how you know your ads actually changed how people perceive your brand. If you see no significant lift, it just means your creative or targeting didn’t resonate, and you need to rethink your approach for the next one. And if you see no lift, learn from it. It’s valuable feedback. As the IAB’s 2024 Video Advertising Report (iab.com/insights/iab-2024-video-advertising-report) notes, even small, consistent lifts can build up into serious brand equity over the long haul.

  5. Pro Tip: Look Beyond the Average

    The overall brand lift number is fine, but you have to dig into the segments. I’ve seen plenty of campaigns that post a boring 5% average lift, but when you look closer, a specific demographic is showing a 15% lift. That granular data is where the gold is, telling you exactly how to refine your creative and targeting for the next round. I always recommend hunting for those outlier segments, because they’re often the key to making the next campaign a much bigger success.

Measuring brand lift gives you critical insight that click-through rates will never show you, giving you a much clearer picture of how your creative actually influences perception and intent. When you take the time to set up and analyze these studies correctly in Google Ads, you get hard data you can use to refine your future campaigns and build a brand that actually resonates with people.

What’s the minimum budget for a Google Ads Brand Lift Study?

Google doesn’t list a minimum dollar amount, but you have to budget enough to hit at least 2 million impressions in 7 days. The actual cost to get there depends entirely on your targeting and bidding, so you’ll have to do the math for your specific campaign.

How long until I see brand lift data?

You should start seeing data populate in the dashboard after your campaign has been running for at least seven days and has hit that 2 million impression minimum. You might see some numbers trickle in sooner, but you need to wait for the full run and impression volume to get statistically significant data you can actually trust.

Can I write my own survey questions?

Not really. Google generates standard questions based on the metrics you pick, like ad recall or brand awareness. Sometimes you can make very minor tweaks, but you can’t rewrite the core questions because that would break the platform’s standardized methodology and make your results invalid.

What’s a good brand lift percentage?

There’s no single “good” number because it completely depends on your industry, your campaign goal, and the metric you’re measuring. For a big campaign, even a 1-3 percentage point lift in something like ad recall can be a huge win. The key is to focus on lifts that are statistically significant, not just some arbitrary number, and to check them against industry benchmarks if you can find them.

What if my study shows no significant lift?

It means your campaign probably didn’t work to change people’s minds. Use it as a clear signal to go back and analyze your creative, targeting, and messaging. It’s time to A/B test some new ad creative or get more specific with your audience segmentation to see if you can get better results next time.
