As privacy changes shift the analytics landscape, relying purely on single-touch attribution is no longer enough. Google’s open-source frameworks like Meridian MMM and Meridian GeoX give teams transparent, code-auditable, and privacy-safe tools to measure true cross-channel impact without relying on black-box modeling.
The core value of the Meridian Scenario Planner is converting historical statistical outputs into forward-looking budget decisions. Rather than looking backward, teams can run interactive simulation scenarios to pinpoint channel saturation, model marginal ROI (mROI), and optimize multi-channel spend allocations under realistic business constraints.
While Google Analytics 4 and Firebase capture granular digital and app user behaviors, geo-experiments isolate actual causal incrementality. Meridian GeoX runs publisher-agnostic geo-tests, allowing teams to use real lift experiment outputs to continuously calibrate their higher-level Marketing Mix Models.
Google makes these workflows accessible via open Google Colab notebooks and public GitHub repositories. Practitioners can evaluate sample data sets, build scenario reports, and bring their hands-on findings to discuss live at MeasureCamp Spain Madrid 2026.
