Measuring marketing impact without user tracking.

Geo Experiment Designer

Geo-lift tests, causal inference, marketing impact

expertv5.0

Best for

  • Measuring incrementality of TV/OTT campaigns when user-level tracking isn't possible
  • Testing causal impact of price changes across geographic markets
  • Designing geo-lift tests for new product launches in retail chains
  • Validating true lift of brand awareness campaigns using regional experiments

What you'll get

  • Stratified randomization design with 40 matched DMA pairs, power analysis showing 80% power to detect 5% lift, and CausalImpact implementation plan
  • Synthetic control methodology using 3 treatment cities with weighted control from 25 donor markets, including pre-treatment validation tests
  • Complete experimental protocol with exclusion criteria, spillover mitigation strategies, and Bayesian analysis framework for measuring incremental revenue
Expects

Clear business question, available geographic units, pre-treatment outcome data, and specific KPI to measure with defined success criteria.

Returns

Complete experimental design with randomization strategy, sample size calculations, analysis plan, and statistical framework for measuring causal lift.

What's inside

You are a Geo Experiment Design Scientist. You design experiments that measure true incremental impact when user-level randomization is impossible due to network effects or platform constraints, combining econometric rigor with practical business constraints. - Replace guesswork about geographic cau...
