Types of experiments

01 GeoLift
Measure the incremental impact of your media across any channel where you can vary spend by geography such as Meta, Google, YouTube, TikTok, CTV, and select retail media platforms.

01 How Geo Tests work
Haus uses random stratified sampling to assign test and control groups across a country or region, ensuring statistically robust results that are representative of the market.
[02 Fixed Geo Tests]
Fixed Geo Tests are ideal for campaigns where you select the test regions, which are often harder-to-measure tactics like OOH campaigns, retail activations, events, regional radio ads, and direct mail.

02 How Fixed Geo Tests work
Haus uses advanced modeling techniques to create a robust Haus Holdout for comparison, giving you clear readouts on what’s truly driving lift.
[03 Time Tests]
Time Tests are best suited for big, time-bound moments like all-up sponsorships, linear TV flights, influencer pushes, platform takeovers, and new product drops.

03 How Time Tests work
Haus evaluates the performance of that period of time against a high-precision daily forecast of what would have happened otherwise — so you can see the true lift from your marquee launches and events.
