Google has launched Scenario Planner, a no-code interface built on top of its open-source Meridian marketing mix model (MMM).
Announced on February 19, 2026, by Harikesh Nair, Senior Director of Data Science & Engineering at Google, the tool is designed to close one of the most persistent gaps in modern marketing operations: the disconnect between advanced analytics and the marketers who need to act on them.
According to a Harvard Business Review Analytic Services report from October 2025, nearly 40% of organisations say they struggle to translate MMM outputs into real-world business decisions — Scenario Planner is Google’s direct answer to that problem.
What Is Google Meridian Scenario Planner and How Does It Work?
Scenario Planner operates as a user interface layer on top of Meridian’s Bayesian statistical framework, which models how different marketing channels contribute to sales over time.
Previously, extracting insights from Meridian required data scientists comfortable with Python, R, or complex regression outputs.
Scenario Planner eliminates that requirement entirely.
Marketers can now access a code-free interface inside Looker Studio, test budget allocation scenarios across channels, and view real-time ROI projections without writing a single line of code.
The tool supports both fixed and flexible budget optimisation modes, allowing teams to test “what-if” scenarios — for example, reallocating 15% of YouTube spend to Performance Max — and immediately visualise projected revenue impact.
Traditional MMM projects historically take 8 to 12 weeks from data collection to actionable insight.
Scenario Planner compresses this to real-time analysis, fundamentally transforming MMM from a retrospective audit into a live planning instrument.

Why Scenario Planner Is a Game-Changer for Marketing Teams
The competitive significance of Scenario Planner extends beyond usability.
It represents Google’s broader strategy of building a horizontal data infrastructure that ties analytics, advertising, and cloud services into a tightly integrated ecosystem.
Brands already running Google Ads and Google Cloud have a natural integration advantage — Scenario Planner becomes a unified budget command centre rather than an isolated analytics tool.
For CMOs managing multi-million dollar media budgets, this means faster decisions with greater confidence, fewer dependencies on external data science consultants, and tighter alignment between campaign performance and P&L targets.
Major brands, including Asos, Urban Outfitters, and Shopify, are already running Meridian models, signalling commercial traction.
As third-party cookie deprecation continues fragmenting digital attribution, MMM is becoming the primary cross-channel measurement methodology for enterprise marketing teams in 2026 — and Scenario Planner makes it more accessible than ever.
