Matched Market Testing (MMT) uses a robust statistical framework to measure the true causal impact of marketing campaigns. By pairing markets based on historical performance and creating a synthetic control group, we can isolate the effect of a marketing intervention from natural market fluctuations
What is Matched Market Testing?
Matched Market Testing (MMT), also known as geo-testing, is a causal inference technique used to measure the incremental lift of a marketing campaign. We divide a set of geographic markets (e.g., DMAs, states) into two groups:
Test Markets: A group of markets where we apply a specific marketing treatment (e.g., increased ad spend, a new channel, or withheld spend).
Control Markets: A group of similar markets where we do not apply the treatment.
By comparing the performance of the test markets to the control markets during the campaign period, we can determine the marketing intervention’s causal effect, or lift.
Why MMT Matters for Your Business
Unlike platform attribution, which often overstates performance, MMT provides true incrementality measurement. This controlled experimental approach ensures you understand what revenue and conversions are actually driven by your marketing investments versus what would have happened naturally.
