How to Run a Geo Lift Test

What is a Geo Lift Test?

A geo lift test is a marketing experiment that helps measure the incremental impact of a marketing campaign by comparing performance across different geographic regions. One group of regions, called the test regions, is exposed to the campaign, while the control regions remain unexposed. By analyzing the differences in performance between the test and control regions, marketers can determine the incremental lift—the additional value created by the campaign that wouldn’t have happened naturally.

Geo lift testing is particularly effective for geographically targeted campaigns, such as regional advertising, localized promotions, or product launches. This testing method helps marketers isolate the true impact of a campaign, providing more reliable insights than simply comparing total sales or conversions.

Why Run a Geo Lift Test?

Running a geo lift test allows marketers to:

Measure the true impact of a campaign in specific regions.
Isolate incremental lift, meaning you can determine how much additional value was created by the marketing activity.
Optimize regional strategies, tailoring campaigns to regions where they perform best.
Make data-driven decisions about future campaigns based on real-world results.

Steps to Run a Geo Lift Test

Here is a step-by-step guide on how to run a geo lift test for your marketing campaigns:

1. Define Your Campaign Objectives

The first step in running a geo lift test is to clearly define your campaign goals. What do you want to measure? Are you aiming to increase sales, drive website traffic, or boost engagement in specific regions? Defining the key performance indicators (KPIs) you want to track will help you measure the success of the campaign.

Example: A retail brand launching a new product may want to measure whether their advertising campaign increases product sales in certain regions.

2. Select the Test and Control Regions

Once your goals are defined, the next step is to select the test and control regions for the geo lift test. The test regions are the areas where your campaign will be active, while the control regions will remain unaffected by the campaign. It's important to choose control regions that are as similar as possible to the test regions in terms of demographics, behavior, and purchasing patterns.

Example: A restaurant chain may choose two similar metropolitan areas—one as the test region where they run targeted ads and promotions, and the other as the control region where no campaign will be introduced.

3. Set Up the Marketing Campaign in the Test Regions

Once the regions are selected, the campaign is launched in the test regions. This could involve running digital ads, placing billboards, sending direct mail, or using other marketing tactics. Ensure that the control regions are not exposed to any elements of the campaign to maintain the integrity of the test.

Pro Tip: Use geo-targeting tools in digital ad platforms to control where your ads are served, ensuring that only the selected test regions are exposed to the campaign.

4. Track Performance Data Across Both Regions

During the campaign, track performance data in both the test and control regions. You’ll want to monitor key metrics such as sales, conversions, website traffic, or other KPIs defined at the start of the campaign. It's important to collect data over the entire duration of the campaign to ensure an accurate comparison between the regions.

Example: If you are running digital ads, you can track metrics like click-through rates (CTR), cost per acquisition (CPA), and total sales attributed to the campaign in the test regions.

5. Analyze the Incremental Lift

After the campaign has concluded, it's time to analyze the results. Compare the performance of the test regions (exposed to the campaign) with the control regions (not exposed) to determine the incremental lift—the additional value generated by the marketing campaign. This can be done by calculating the difference in performance between the two regions.

Incremental Lift Formula:

Incremental Lift=(Test Region Performance−Control Region PerformanceControl Region Performance)×100\text{Incremental Lift} = \left( \frac{\text{Test Region Performance} - \text{Control Region Performance}}{\text{Control Region Performance}} \right) \times 100Incremental Lift=(Control Region PerformanceTest Region Performance−Control Region Performance)×100

This formula helps calculate the percentage lift achieved by the campaign in the test regions compared to what would have happened without the campaign.

6. Integrate the Results with Other Marketing Models

Once the geo lift analysis is complete, you can integrate the results with broader marketing measurement models. Combining the insights from the geo lift test with models like Marketing Mix Modeling (MMM) and Multi-Touch Attribution (MTA) helps you get a unified view of how your campaign performed across regions and channels.

At Rockerbox, we integrate geo lift testing into our comprehensive unified measurement solution, ensuring that your marketing performance is viewed from every angle and helping you make more informed decisions about future campaigns.

7. Optimize Future Campaigns Based on Insights

The final step is to use the insights gained from the geo lift test to refine your future marketing efforts. By identifying which regions or tactics delivered the highest incremental lift, you can optimize your strategy, allocate budgets more effectively, and drive better results in future campaigns.

Example: If the geo lift test shows that your ads performed exceptionally well in one region but not in another, you can reallocate your marketing budget to focus on high-performing areas or adjust your strategy in the underperforming regions.
