Marketing Mix Modeling Guide

Introduction to Marketing Measurement

Marketing measurement is critical for quantifying the impact of marketing efforts and optimizing budget allocation. From traditional econometric models to advanced attribution techniques, these strategies reveal what drives sales and return on investment (ROI). We regularly see 10-20%+ improvements in ROI and/or revenue after optimizing our clients’ mix of media, creative, pricing, regional, and promotional strategies. Today, we are even optimizing daily impressions to maximize sales. It is a holistic solution and representative of our industry’s most evolved approach.

This comprehensive yet accessible guide explores Marketing Mix Modeling (MMM), its evolution, and other key measurement strategies, grounded in academic literature and analyst insights from Gartner. We compare their strengths and limitations, highlighting why Polaris Research’s solution leads the way in today’s privacy-conscious, multi-channel landscape.

What is Marketing Mix Modeling?

Marketing Mix Modeling (MMM) is a statistical approach that analyzes historical data to measure the effectiveness of marketing channels (e.g., TV, digital, print) and external factors (e.g., economic trends, competitor actions). Using regression analysis, MMM decomposes sales into base and incremental components, guiding marketers to allocate budgets for maximum ROI.

Key Components of MMM

Base Sales: Sales driven by non-marketing factors like brand equity or market demand.
Incremental Sales: Sales directly attributable to marketing efforts.
Diminishing Returns: The point where additional spend yields reduced impact (Kotler & Keller, 2016).
Carryover Effects: The lingering impact of campaigns over time (e.g., a TV ad’s effect beyond its air date).
External Factors: Macroeconomic indicators, pricing, or promotions influencing outcomes.

Limitations of Traditional MMM

Data Aggregation: Uses coarse, historical data (weekly/monthly), missing real-time interactions.
Channel Silos: Struggles to capture cross-channel synergies (e.g., how social ads boost search conversions).
Complex Inputs: Often requires extensive datasets, delaying implementation.
Privacy Challenges: Limited granularity in a cookie-less world (Verhoef et al., 2015).

Why MMM Matters

MMM provides a top-down view of marketing performance, ideal for strategic planning. A 2018 study in Journal of Marketing Research found that MMM can improve ROI by 10–15% when properly implemented (Hanssens et al., 2018).

Evolution of Marketing Measurement Strategies

Marketing measurement has evolved significantly since the 1960s, driven by technological advancements, changing consumer behaviors, and privacy regulations.

1. Marketing Mix Modeling (MMM)

Emergence: Originating in the 1960s, MMM was developed to optimize traditional media like TV and radio using econometric models to analyze historical sales data (Hanssens, 2015).
Evolution: By the 1990s, MMM expanded to include early digital channels (e.g., banner ads), focusing on strategic budget allocation across aggregated channels.
Characteristics: Relies on regression to estimate channel contributions; excels in long-term planning but struggles with granular, cross-channel insights.
Impact: Set the foundation for data-driven marketing but was limited by siloed data and slow implementation.

2. Brand Lift Studies

Emergence: Gained prominence in the 1980s as brands sought to measure upper-funnel metrics like awareness and perception through surveys (Tellis, 2004).
Evolution: By the 2000s, digital platforms enabled scalable online surveys, but the approach remained focused on qualitative outcomes.
Characteristics: Captures non-sales impacts; privacy-compliant but disconnected from direct sales attribution.
Impact: Added a qualitative dimension to measurement but lacked precision for ROI-focused strategies.

3. Incrementality Testing

Emergence: Popularized in the early 2000s with the rise of controlled experiments in digital advertising (Gordon et al., 2019).
Evolution: By the 2010s, incrementality testing became a staple for validating campaign lift through test and control groups, especially in digital channels.
Characteristics: Isolates causal impact but is resource-intensive and hard to scale across multiple channels.
Impact: Improved accuracy for specific campaigns but couldn’t address complex, multi-channel journeys.

4. Multi-Touch Attribution (MTA)

Emergence: In the 2010s, MTA emerged with the growth of digital marketing, leveraging user-level data to track touchpoints (e.g., social ad → search → purchase) using models like linear or time-decay (Li & Kannan, 2014).
Evolution: Fueled by third-party cookies, MTA offered granular insights but faced challenges with privacy regulations post-2018 (Berman et al., 2020).
Characteristics: Excels in digital environments but struggles in cookie-less settings and with offline channels.
Impact: Shifted focus to user-level journeys but exposed vulnerabilities in a privacy-first world.

5. Unified Marketing Measurement (UMM)

Emergence: By the mid-2010s, UMM arose to bridge MMM’s strategic insights with MTA’s granularity, aiming for holistic measurement (Chapman & Feit, 2019).
Evolution: Supported by advanced analytics, UMM integrated aggregated and user-level data to model cross-channel synergies, aligning with omnichannel trends (Verhoef et al., 2015).
Characteristics: Offers robust synergy capture but requires complex data integration, limiting accessibility.
Impact: Paved the way for omnichannel approaches but remained complex and slow to implement.

6. Polaris Research’s Omnichannel Attribution and Optimization

Emergence: Developed in the 2020s, Polaris’s solution builds on MMM and MTA, addressing privacy and complexity challenges in the post-cookie era (Dinner et al., 2021).
Evolution: Leveraging AI and machine learning, it uses simple historical inputs (weekly sales, macroeconomic indicators, promotions, creative, product launches, digital impressions) to deliver granular DMA and store-level insights via cascading models. Gartner highlights the need for such agile, conflict-free solutions.
Characteristics: Combines speed (4 weeks to results), privacy compliance, and high granularity (impressions, DMAs, stores, products); captures cross-channel synergies effectively.
Impact: Represents the most evolved strategy, aligning with academic calls for omnichannel accuracy and Gartner’s push for software-driven measurement.

A 2021 study in Journal of Marketing found that omnichannel attribution models improve accuracy by 20–30% over traditional MMM or MTA alone by capturing cross-channel synergies (Dinner et al., 2021). Polaris’s cascading models align with this, delivering precise, localized insights.

Polaris Research’s Omnichannel Attribution and Optimization Solution

Our omnichannel attribution and optimization solution, detailed at Marketing Mix Manager, is the most evolved marketing measurement strategy. It blends MMM’s econometric rigor with MTA-inspired granularity, using only simple historical inputs—no real-time user data required. Leveraging machine learning, our cascading models deliver granular results at the DMA and store level, enabling precise optimization across regions and retail locations.
