Optimizing media budgets for a 5% ROI boost.

The client, a major retailer investing €5 million annually in marketing, faced growing pressure to argue for their marketing spend. Changing competitive and economic environments required a rethinking of their tradition marketing investment heuristics. An optimal solution that complemented the marketer’s experience with quantitative methods from Bayesian statistics was developed to quantify marketing effectiveness and optimize campaign investments.
THE SITUATION

Lack of data-driven insights hindered growth.

The client’s marketing strategy heavily depended on intuition and historical best practices. The absence of data-backed insights made it difficult to measure effectiveness across campaigns or adapt to evolving marketing channels. Their inability to correlate investments with sales and brand growth led to inefficiencies, missed opportunities, and difficulty defending decisions to stakeholders.

THE CHALLENGE

Proving marketing ROI across channels.

The client’s reliance on traditional marketing practices created several obstacles, making it difficult to achieve measurable growth and defend their marketing investments.
Their challenges included:

  • Difficulties in quantifying the impact of marketing investments across different channels
  • Lack of clarity on how channels influenced one another
  • Systematic integration of pre-existing marketing knowledge with advanced quantitative methods
  • Increasing demands to justify marketing budgets with data-backed results.
OUR APPROACH

Building a data-driven Marketing Engine.

To address the client’s challenges, we designed and implemented a comprehensive data-driven solution. This engine integrated advanced econometric models, campaign-specific insights, and automated testing, enabling the client to move from intuition-based decisions to actionable, ROI focused strategies.

Our tailored approach included:

  • Advanced econometrics: developed Bayesian hierarchical models to integrate historical intuition-based data, cross channel effects and data trends.
  • Campaign-level insights: split marketing spends across TV, programmatic ads, and social media for granular analysis and targeted optimization.
  • Geo-based A/B testing: introduced automated regional testing to establish causal relationships between marketing investment and sales.
  • Incremental optimization: iteratively refined modelling to transition from intuitive, experienced-based analysis to data-backed. actionable, ROI-driven decisions.

This approach helped the client gain a clearer understanding of their market and revealed that some long-standing intuitions and assumptions were inaccurate. Now, the client is empowered to leverage data-backed insights to make smarter decisions and more effective investments in their marketing efforts.
