Google has officially launched Meridian, its open-source Marketing Mix Model (MMM) designed to help marketers make data-driven budget decisions. Alongside this, Google is introducing a partner program with over 20 certified measurement partners to assist with implementation.

Why Meridian?
Traditional MMMs struggle to measure performance media, like Search Ads and AI-powered campaigns. Meridian, however, leverages Bayesian causal inference to provide more accurate, granular insights into marketing impact.
Key Benefits of Meridian:
✅ Better Performance Measurement: Understand the true impact of Google Ads, including Search and YouTube.
✅ Customizable & Transparent: As an open-source framework, businesses can modify the code to suit their needs.
✅ Smarter Budget Allocation: Optimize budgets by analyzing sales, conversions, and profit KPIs.
✅ Accurate Reach & Frequency Insights: Goes beyond impressions to assess true audience engagement.
✅ Integration with Experiments: Uses incrementality experiments for real-world validation of marketing impact.
Getting Started with Meridian
Marketers can download Meridian’s code on GitHub or work with Meridian Certified Partners for expert support.
With continuous improvements and new features on the horizon, Meridian is set to redefine how marketers approach data-driven decision-making.
Here is the official announcement: Meridian is now available to everyone!
