You Just Ran an MMM, Now What? Understanding Media Mix Modeling for Advanced Marketing Leaders
‍

Introduction

Media Mix Modeling (MMM) is a powerful tool for understanding how different marketing channels contribute to business performance. But running an MMM is only the beginning. Once you have your results, the real challenge is translating them into actionable marketing strategies. Without a clear understanding of how to apply these insights, MMM can feel like just another complex data project with no tangible impact.

In this guide, we’ll explore how to effectively leverage MMM insights, make strategic adjustments, and determine when to update your model for ongoing success.
‍

Interpreting Your MMM Results

MMM results can be overwhelming, but breaking them down into key elements will help make them more actionable.

1. Channel Contribution

Examine the percentage of total sales or key performance indicators (KPIs) attributed to each media channel. This insight helps identify which channels drive the most impact. For example, a DTC brand might discover that influencer marketing contributes more to customer acquisition than expected, leading them to shift budget allocations accordingly.

2. Return on Investment (ROI)

MMM provides a clearer picture of the ROI for each marketing channel. If paid social campaigns show diminishing returns while email marketing maintains strong efficiency, a strategic budget reallocation may be necessary.

3. Optimal Media Mix

The model suggests an ideal budget distribution across channels based on past performance. However, blindly following these suggestions without validation can be risky. Testing incremental budget shifts before making large reallocations is key.

Taking Action on MMM Insights

Once you understand your results, it’s time to optimize your marketing approach.

1. Reallocate Budgets

Shift spending from underperforming channels to those with higher ROI. If display ads show a lower return compared to paid search, reduce display investment and increase PPC spending.

2. Adjust Channel Strategy

MMM can reveal unexpected synergies between channels. If search and social ads perform better together, aligning messaging across both can amplify results.

3. Improve Targeting

Refining audience segments based on MMM insights helps improve conversion rates. If a particular demographic responds better to video content, adjust targeting parameters accordingly.

4. Optimize Creative and Messaging

MMM highlights which creative formats perform best in different channels. Use this information to tailor messaging, visuals, and ad placements for maximum impact.

5. Refine Timing

If seasonality plays a significant role in performance, schedule campaigns accordingly. A travel brand, for example, may use MMM to identify peak booking periods and optimize ad spend for those windows.
‍

Continuous Learning and Validation

MMM is not a one-and-done exercise. Regular testing ensures continued accuracy and effectiveness.

1. A/B Testing

MMM provides directional insights, but controlled experiments validate changes. Run A/B tests on budget reallocations and messaging to confirm findings.

2. Monitor Short-Term Impact

Keep an eye on short-term performance metrics like CPA, ROAS, and conversion rates after implementing MMM recommendations.

3. Adjust Based on Market Conditions

If external factors such as economic downturns or competitor moves change the playing field, re-run MMM to adjust strategy accordingly.

When to Update Your MMM

Keeping your model current ensures its recommendations remain relevant.

• Annually or Semi-Annually: Most businesses should update their MMM at least once a year, or more frequently in fast-changing industries.
• After Major Campaigns: Running an MMM post-campaign helps refine future media planning.
• In Response to Market Changes: If there are major shifts in consumer behavior or competitor activity, updating your MMM can reveal new strategic opportunities.
• When Data Availability Increases: The more high-quality data you have, the more accurate your MMM will be. If significant new data becomes available, it’s time for a refresh.

Why Many MMMs Fail (And How to Avoid It)

MMM has a reputation for being complex and, in some cases, unreliable. Here’s why:

1. Manipulated Insights

Many agencies tweak MMM results to justify pre-existing assumptions. This leads to inflated channel effectiveness and poor decision-making. Stella eliminates this by using transparent, AI-driven modeling.

2. Misinterpreted Results

MMM outputs require proper interpretation. Many marketers struggle with this, leading to poor execution. Stella acts as your AI Data Scientist, explaining what the results mean and how to act on them.

3. High Costs and Gatekeeping

Most MMM solutions cost anywhere from $15,000 to $80,000, making them inaccessible for many businesses. These prices exist because agencies know most marketers don’t fully understand MMM, so they charge premium fees. Stella is the most affordable MMM on the market, offering the same level of accuracy without the excessive costs.
