Google Meridian MMM: A Powerful Tool, But Is It Right for You?
Marketing Mix Modeling (MMM) is making a big comeback. With third-party cookies disappearing, iOS privacy changes limiting tracking, and ad platform reporting becoming less reliable, marketers are looking for privacy-safe ways to measure true channel performance.
In 2023, Google launched Meridian, a free, open-source MMM solution. It promises a transparent, flexible way to understand what is really driving sales across your marketing mix. But here is the catch: while the software is free, the setup can be costly in time, resources, and expertise.
So, is Google Meridian the right MMM solution for your e-commerce brand? And if not, what is the better alternative? Let’s break it down.
What is Google Meridian MMM?
Google Meridian is an open-source Marketing Mix Modeling framework designed to help marketers:
- Measure the incremental lift of each channel
- Understand long-term and cross-channel effects
- Operate in a privacy-first environment without user-level tracking
How it works:
- Aggregates historical marketing and business data such as spend, impressions, clicks, conversions, and revenue
- Incorporates external variables like seasonality, promotions, and market trends
- Uses Bayesian modeling to estimate each channel’s contribution to sales and ROI
- Outputs results that inform budget allocation decisions

The Challenges of Using Meridian Alone
While Meridian is free to download, it is not “plug and play.” Here are the most common challenges marketers face:
1. Complex Setup
- Requires manual API connections to all your ad platforms
- Needs at least two years of clean, organized historical data
- Involves data cleaning, transformation, and formatting before you can even start modeling
You can read more about MMM data requirements here: What Data Do You Need for Marketing Mix Modeling Success?
2. Resource Requirements
- You will need analysts or data scientists who can write code, run Bayesian models, and interpret the results
- Even experienced teams can spend weeks or months just preparing the dataset
3. Limited Actionability
- Meridian outputs strategic insights, but does not directly integrate with your campaign management tools
- No real-time optimization, meaning you still have to manually implement changes based on the model’s results
Who Meridian Works Best For
Meridian in its raw form is best suited for:
- Large enterprise brands with in-house data science teams
- Agencies offering MMM as a managed service
- Organizations already running MMM that want to customize the model code
If that is not you, the costs in time and labor can outweigh the benefits.
