At GML 2026 Google announced three new Meridian surfaces: Meridian in GA360 (turnkey MMM in Google Analytics 360), Meridian Studio (a Google Cloud enterprise platform with native agentic AI for data quality and scenario planning), and Meridian GeoX (an open-source geo-based incrementality calibration engine). Product Manager Katie Munro and Developer Relations Engineer Jeff Li discussed the math, use cases, and implementation paths. The post was authored by Cory Liseno of Google’s Advertising and Measurement Developer Relations team.
