Imagine investing millions into marketing campaigns without knowing how much Revenue or Gross Profit they drive for our company. Shockingly, over 60% of companies admit they cannot confidently measure the ROI of their marketing efforts. This isn't just a minor oversight—it's a critical pain point leading to wasted resources, misallocated budgets, and untapped revenue potential. For most companies, especially in the mid-market space where we mostly operate, every dollar of OPEX counts. The inability to quantify marketing impact is not just a minor inconvenience, it's dangerous long-term if we don't address it.

Traditional measurement methods are failing us. Outdated models like last-touch attribution offer a fragmented and misleading view of the customer journey, ignoring the complex web of interactions across multiple channels and touchpoints. This leaves marketing and other commercial teams in the dark, making strategic decisions based on incomplete or inaccurate data.

But what if there was a relatively straightforward way to understand the impact of your marketing investments and help you optimize your marketing budget? 

Enter Marketing Mix Modeling (MMM), a statistics and machine-learning-based approach enjoying a renaissance in how companies understand and optimize their marketing investments. MMM doesn't just report ROI numbers; it deciphers the intricate dynamics of marketing efforts, providing a holistic and actionable framework for maximizing revenue growth across omnichannel marketing investments.

Our latest article follows our popular webinar in November on In-Sourcing Your Marketing Mix Modeling. It shows you how to leverage popular, open-source toolkits to build your own MMM capability to drive measurable marketing returns. We'll discuss the evolution of marketing analytics, dissect the core components of MMM, and provide you with actionable steps on building this capability inside your companies.

But why are we talking about Marketing Mix Modeling in the context of Revenue Growth Analytics & Management? 

Revenue Growth Management (RGM) is often mistakenly reduced to just pricing & promotional strategies. While pricing is undeniably a cornerstone of RGM, it’s only one piece of the puzzle. True RGM is about driving sustainable, profitable growth across all commercial activities—and that includes the strategic alignment of sales and marketing excellence.

This is where Marketing Mix Modeling (MMM) becomes a critical enabler. By analyzing the incremental impact of different marketing activities on sales, MMM empowers organizations to optimize marketing spend, quantify ROI across channels, and make data-driven decisions that directly boost Sales and Gross Profit. It’s not just about understanding what works in your marketing mix—it’s about identifying where your next dollar will deliver the greatest impact.

A holistic approach to RGM recognizes that growth doesn’t happen in silos. Pricing strategies, promotional effectiveness, sales enablement, and marketing optimization are all interconnected. Advanced tools like MMM provide the analytics foundation to break down these silos, offering actionable insights that align marketing efforts with broader revenue goals.

Ultimately, RGM is about building a growth engine that integrates pricing, marketing, and sales into a seamless strategy. With MMM as part of your Revenue Growth Analytics toolkit, you can transform marketing from an expenditure into a powerful driver of sustainable, long-term profitability.

Understanding Marketing Mix Modeling Fundamentals

Marketing measurement has come a long way since the 1950s when academic researchers first introduced the concept of Marketing Mix Modeling. The initial models were rudimentary, often relying on simple correlations between lagged sales and marketing spending. However, the advent of big data in the 1990s marked a significant turning point. Companies began investing heavily in data collection and analysis, transforming marketing from an art into a science. This shift enabled businesses to gain deeper insights into customer behaviors, preferences, and the effectiveness of various marketing channels.

In recent years, the rise of digital marketing and the increasing focus on data privacy have accelerated the adoption of MMM. Traditional attribution models, particularly last-touch attribution, have proven insufficient in capturing the complex, multi-channel customer journey. A survey revealed that 61.4% of marketers now prioritize better and faster media mix modeling as their primary measurement strategy. 

Companies of all sizes are turning to MMM to navigate the intricate digital landscape and drive sustainable growth.

Core Components of Marketing Mix Models

Modern Marketing Mix Models combine frequentist or Bayesian statistics, augmented with machine learning and optimization algorithms. At its core, a MMM is a demand model (typically predicting revenues) that dissects and analyzes a host of factors that influence sales. The factors influencing sales can be generally categorized into “Base” and “Incremental” drivers.

“Base” drivers represent the foundational elements contributing to sales without any marketing activity (i.e. What would my revenue be in the absence of any marketing spend?). “Incremental” drivers capture the short—and medium-term sales variations resulting from marketing efforts. 

By analyzing these components, MMM dissects the total sales figures to attribute contributions, isolating the effects of various marketing activities from other influencing factors.

Key Benefits for Profitable Revenue Growth

Implementing Marketing Mix Modeling offers several critical advantages for commercial leaders who want to optimize their marketing spend:

1. Enhanced ROI Measurement: While MMM is not ideal for campaign-level ROI analysis, it is preferred over basic attribution models that often deal with signal loss and are most often based on “last touch” approaches for near-term, channel-level ROIs. When done right, the appropriate MMM provides a clear, quantifiable link between marketing efforts and revenue generation. Companies can accurately (or at least, directionally accurately) measure the return on investment for each marketing channel and sub-channel, justifying expenditures and making insights-driven budgetary decisions.

2. Smarter Budget Planning: With insights into the diminishing returns and saturation points of each marketing channel, businesses can allocate budgets more effectively. MMM identifies the most efficient ways to distribute spending across channels, reducing waste and maximizing impact towards achieving your revenue goals.

3. Improved Forecasting: By understanding how different marketing and other factors interact and contribute to sales, companies can develop more accurate sales forecasts. This integrated view better supports strategic planning and helps anticipate the impact of market changes (i.e. changes in competitor pricing strategies).

For instance, recent MMM projects in the nonprofit space have uncovered that digital channels often perform better than traditional, last-touch attribution methods suggest (based on “last-touch” attribution). Companies leveraging these insights have restructured their marketing investments, leading to improved results across all channels. 

Building a Business Case for MMM

Developing a compelling business case for Marketing Mix Modeling (MMM) starts with understanding current measurement gaps, assessing the complexity of your marketing mix, and highlighting the potential return on investment. Our recent webinar discussed that most companies still struggle with effective measurement strategies. Revology Analytics' research shows that nearly 70% of mid-market companies struggle to measure the impact of their marketing investments on the bottom line. This highlights the urgent need for companies to adopt MMM as a foundational marketing analytics capability.

One of the key insights from our webinar was that many companies over-rely on last-touch attribution, with most firms who employ multi-touch attribution (MTA) using “last-touch” as their primary method. Last-touch attribution is increasingly ineffective in capturing the full impact of marketing activities across multiple channels. Of the ~ 30% of mid-market firms that can quantify the impact of their marketing investments, we found that only 20% currently leverage MMM, while about 25% use both MTA and MMM. This represents a significant opportunity for improvement.

Companies often face significant challenges in evaluating their marketing performance due to:

• Inadequate Attribution Methods: Over-reliance on last-touch or single-touch attribution models fails to capture the multi-channel customer journey, leading to misleading conclusions about channel effectiveness.

• Siloed Channel Measurements: Isolated analysis of marketing channels prevents a holistic understanding of how channels interact and influence each other.

• Limited Cross-Channel Visibility: Without an integrated view, companies cannot identify synergies or overlaps between channels, resulting in inefficient spending.

• Partial ROI Understanding: A lack of comprehensive measurement tools hampers the ability to demonstrate marketing's true return on investment.

Recognizing these gaps is the first step toward advocating for MMM within the organization.

ROI Potential Analysis

Marketing Mix Modeling presents a significant opportunity for enhancing investment returns. Studies have shown that companies can drive up to a 50% absolute improvement in their Marketing ROI by strategically allocating their marketing budgets based on MMM insights. The analysis typically uncovers opportunities in three key areas:

• Channel / Sub-Channel Optimization: Identifying underperforming channels or those with high growth potential to maximize returns.

• Budget Reallocation: Shifting funds from low-impact to high-impact channels based on model results.

• Performance Forecasting: Anticipating future revenue and profit changes by modeling different marketing spending scenarios.

For example, a company might discover through MMM that reallocating 15% of its budget from TV to Instagram could yield a 20% increase in revenues. Such tangible and quantifiable ROI projections strengthen the business case for building or in-sourcing MMM capabilities.

Stakeholder Alignment Strategy

Successful implementation of MMM hinges on organization-wide support. Collaboration between marketing, finance, and sales departments is crucial for data sharing and strategic alignment on model results and implications. Key elements of effective stakeholder alignment include:

• Data Collection: Establishing robust processes to ensure data accuracy, consistency, and regular validation. This means that the organization must stand up a purpose-built data mini-data warehouse that holds all relevant marketing data. By data warehouse, you don’t necessarily have to store this data in a typical cloud DW - Excel is more than enough for this. Just ensure that it’s readily available and accessible.

Luckily, for Marketing Mix Modeling, you don’t need any detailed data. Daily or weekly marketing spend by channel and sub-channel often suffices - depending on how many years of data you leverage for modeling. If you are running a MMM based on 1 year’s of information, you will need daily data. If you run a long-range MMM, having 3-4 years of data is ideal, and weekly frequency will suffice.

• Cross-Functional Collaboration: Encouraging cooperation between departments (i.e. from the Marketing to the Data Science team) to facilitate data access and rapid MMM prototyping.

• Communication Framework: Developing clear channels and communication methods for sharing insights, results, and recommendations from MMM analyses. Internal Data Science teams must work closely with both Marketing and Sales throughout the model development process. Another important point here is that analysts must focus on relaying the insights in a simple, easy-to-understand manner, emphasizing strategic implications and recommendations first, before going into the technical details (which should be kept to a minimum for executive audiences).

Implementing MMM Successfully

Achieving success with Marketing Mix Modeling requires meticulous attention to data quality, methodological rigor, and continuous refinement. Organizations that invest in high-quality data inputs and robust modeling processes report significantly better outcomes. Typically, MMM requires at least three years of historical data (if modeling on weekly data) to capture sufficient variability and account for different market conditions. 

The successful implementation of Marketing Mix Modeling (MMM) requires a strategic approach that integrates advanced analytics with practical business insights. Here are the key elements for implementing MMM effectively:

1. Define Clear Objectives: Start by clearly defining what you aim to achieve with MMM—optimizing budget allocation, understanding channel effectiveness, or improving forecasting accuracy. Having well-defined goals ensures that your MMM efforts are aligned with broader business objectives.

2. Prioritize Data Quality: High-quality data is fundamental to building reliable models. Companies must ensure they have access to comprehensive data sets that include marketing spend, impressions, revenues, pricing and promotional data, competitor data if available, and external factors like seasonality or macroeconomic indicators. 

3. Adopt an Iterative Approach: MMM should be treated as an ongoing process rather than a one-off project. Implementing a 'test and learn' mindset allows organizations to refine their models continuously, adapting to changing customer dynamics and improving predictive accuracy over time. Regular iteration also helps identify previously omitted variables that may impact marketing performance.

4. Utilize Open-Source and Affordable Tools: With technological advancements, implementing MMM has become more accessible. Tools like Meta's Robyn or Google's Meridian can help companies start with MMM without massive budgets. These tools provide a great starting point for building initial models and gaining insights into marketing performance.

5. Upskill Teams: Upskilling internal analytics or data science teams is crucial for the successful deployment of MMM. Building internal expertise in marketing science allows companies to take full ownership of their MMM processes. Training programs, workshops, and collaboration with experts can help teams understand the nuances of MMM and leverage the insights more effectively.

6. Manage Organizational Change: Implementing MMM often requires significant changes in how marketing performance is measured and how decisions are made. Effective change management is crucial for ensuring the smooth adoption of MMM. This includes clear communication about the benefits of MMM and setting realistic expectations—that MMM is best for channel/sub-channel level marketing optimization vs. detailed campaign-level analysis (for which some attribution method is more appropriate). 

7. Focus on Incrementality and Diminishing Returns: Understanding the incremental impact and marginal return of each marketing channel is a core strength of MMM. Identifying saturation points and diminishing returns is crucial for optimizing spending. By analyzing these inflection points, companies can decide where to increase or cut back on marketing investments, even in otherwise positive ROI channels.

Model Development Process

Developing a robust Marketing Mix Model (MMM) involves several critical steps to ensure the model accurately reflects the dynamics of the business and provides actionable insights:

1. Data Collection and Preparation: Gather comprehensive data on marketing spend, impressions, revenues, and other influencing factors such as seasonality, economic conditions, and competitor activity. This data should be structured and validated to ensure accuracy. As mentioned above, this data doesn’t need to rely on some data warehouse - after all, we are often talking about a few hundred rows of data with 15-20 variables. We just need to ensure that the data is readily available and updated frequently.

2. Variable Selection and Testing: Carefully select the variables that will be included in the model - combine highly correlated variables, or exclude ones that have little to no explanatory power on revenues. Use statistical or machine learning techniques to identify the most predictive variables (e.g.: through variable importance) and to avoid multicollinearity, which can distort the results.

3. Model Parameter Estimation: With most open-source MMM algorithms, you can use built-in functions to estimate the relationships between variables and sales, accounting for diminishing returns and ad stock effects. Techniques like ridge regression or Bayesian modeling can help manage variable correlation and improve model accuracy.

4. Ad Stock and Diminishing Returns: Include transformations in the model to account for real-world phenomena like ad stock and diminishing returns. Ad stock captures the delayed impact of marketing activities while diminishing returns reflect the reduced effectiveness of increased spending. Again, with most open-source MMM tools, these are automatically included - you just need to have a good idea of what your channels’ adstock and diminishing returns look like (i.e. at least have an idea of what the range is, so you can find optimal values within that range).

5. Model Refinement and Optimization: Continuously refine the model based on performance metrics such as R-squared values or Mean Absolute Percentage Error (MAPE). 

6. Scenario Analysis: Conduct scenario analyses to predict the outcomes of different investment levels at the channel-subchannel level. This helps understand the potential impact of reallocating budgets, adjusting spending levels, or launching new campaigns.

Research indicates that 61.4% of marketers focus on improving the speed and quality of their media mix modeling, underscoring the importance of an efficient and iterative development process.

Validation and Testing Approaches

Validating the accuracy and reliability of Marketing Mix Models (MMM) is crucial to ensure the insights derived are actionable and trustworthy. You can employ several validation and testing approaches to enhance model credibility:

1. Hold-Out Testing: Hold-out testing involves splitting the data into training and testing sets. The model is trained on historical data and then tested on a hold-out sample to evaluate its predictive accuracy. This method helps ensure the model can generalize to unseen data. Most open-source MMM already have this built-in.

2. Conversion Lift Tests: Conversion lift testing validates the impact of marketing activities on sales or conversions. By comparing regions or groups with increased marketing spending against control groups, companies can determine the incremental effect of marketing efforts.

3. Dynamic Budget Optimization: Apply model recommendations to optimize marketing budgets dynamically. Monitor the impact of budget changes on key performance indicators (KPIs), such as sales lift or return on investment (ROI), and compare to modeled predictions to assess model accuracy, and fine-tune future spending decisions.

4. Cross-Validation: Cross-validation involves dividing the data into multiple subsets and using different combinations of training and validation sets to test model accuracy. This method reduces the risk of overfitting and ensures model robustness. Like hold-out testing, most MMM algorithms will have a cross-validation option as part of your model evaluation process. 

5. Benchmark Against Historical Performance: Compare model predictions against historical sales and performance data to check alignment. If there are any significant discrepancies, investigate them and adjust the model as necessary.

6. Marginal ROI Analysis: Calculate the marginal ROI for each marketing channel to identify whether additional spend in a channel will yield positive returns. This analysis helps in understanding the diminishing returns effect and ensures that the model recommendations are in line with profitable growth. 

7. Real-World Experimentation: Conduct real-world experiments such as A/B testing or geolift experiments to validate model predictions. This approach helps understand the true causal impact of marketing activities and provides an additional layer of confidence in the model's recommendations.

8. Stakeholder Review and Feedback: Engage with key marketing stakeholders across marketing, finance, and sales to review the model outputs and gain feedback. This collaborative approach ensures that the model not only makes statistical sense but also aligns with practical business insights, and it also generates buy-in from key commercial stakeholders. 

Companies that regularly validate their models often achieve 20-30% higher accuracy in their marketing predictions. Advanced MMM applications may incorporate both traditional and Bayesian statistical techniques, with 75% of successful implementations using a hybrid approach to enhance accuracy. This allows organizations to capture both short-term performance indicators and long-term brand-building effects.

Optimizing Revenue Through MMM Insights

Marketing Mix Modeling provides a powerful lens through which organizations can scrutinize their marketing investments, optimize channel performance, and drive revenue growth. By leveraging MMM insights, companies can make evidence-based decisions that significantly enhance marketing ROI.

Channel Effectiveness Analysis

Understanding the incremental contribution of each marketing channel is vital for optimization. MMM enables organizations to analyze channel effectiveness based on:

• Incremental Revenue Contribution: The additional revenue each channel generates beyond the baseline.

• Channel-Specific ROI: The return on investment for each channel, considering both costs and incremental revenues.

• Saturation Points: The level of spend at which additional investment in a channel yields diminishing returns.

• Decay Rates: The rate at which the impact of marketing activities diminishes over time.

• Cross-Channel Synergies: How channels interact and amplify each other's effects.

For instance, an MMM analysis might reveal that while a company's spending on paid search yields high immediate returns, there is untapped potential in social media channels that exhibit strong cross-channel synergies.

Budget Allocation Optimization

With insights from MMM, companies can strategically reallocate their marketing budgets to maximize ROI. Key steps in budget optimization include:

1. Assess Current Performance: Analyze the effectiveness and saturation levels of each channel.

2. Identify Reallocation Opportunities: Determine where reducing spend may have minimal impact and where increasing spend could drive significant gains.

3. Model Spending Scenarios: Simulate various budget allocation strategies to forecast potential outcomes.

4. Implement Optimized Budget: Adjust the marketing spend based on model recommendations.

5. Monitor and Adjust: Continuously track performance and refine the budget allocation as needed.

Research shows that organizations using MMM for budget optimization typically achieve a 15-20% increase in marketing ROI (and up to 50% improvement) by reallocating budgets from low-performing to high-impact channels.
