How to maximize marketing ROI when budgets are tight: the role of Marketing Mix Modeling

Are you marking the most of your marketing investment?

When every cent of your marketing budget counts, guesswork becomes a luxury you can't afford. Yet, many businesses still rely on intuition or siloed KPIs to allocate spend across channels. The result? Wasted budget, missed opportunities, and strategies that can’t be defended when results falter.

According to Gartner, 75% of CMOs face pressure to “do more with less”[1], yet only a fraction use data-driven frameworks to guide decisions. The truth is, optimizing marketing ROI in a constrained environment isn't just possible—it’s necessary.

In this article, you’ll discover why most companies fail to adapt their marketing strategy in times of budget cuts—and how a proven, structured approach like Marketing Mix Modeling (MMM) can help you maximize impact with clarity and confidence

The pain point: Navigating uncertainty withlimited visibility

Tight budgets force tough choices. But many marketing teams face three recurring challenges:

1. Lack of visibility across channels

It's easy to know how many clicks your digital ads generated. But how do you weigh that against a TV spot or a retail activation? Most reporting tools operate in silos—making it nearly impossible to see the full picture of what’s working.

2. Short-term wins, long-term losses

When budgets shrink, there's a temptation to cut upper-funnel activities—such as TV campaigns, brand awareness videos, sponsorships, display advertising...— and over invest in short-term performance tactics. But this often leads to short-term spikes at the expense of long-term brand health and future revenue.

3. Decision paralysis

Without robust evidence, every marketing decision becomes a gamble. Teams struggle to justify budget allocations to leadership, leading to missed opportunities or overly cautious strategies.

A CMO survey found that 61% of marketing leaders fail to use ROI in decision making because they aren’t confident in their own data.[2]

The solution: a smarter way to allocate budget

Enter Marketing Mix Modeling—a statistical approach that quantifies the impact of each marketing lever on business outcomes (like sales or leads). Unlike last-click attribution or basic dashboards, MMM gives you a holistic, data-driven view of what actually drives performance.

Here’s how to make it work for your business:

1.       Start with the right question

Don't ask, "How did my last campaign perform?" Instead, ask: "What is the incremental value of each marketing activity—and how should I allocate budget to maximize ROI?"

2.       Break down silos

MMM incorporates both online and offline touchpoints—TV, social media, radio, paid search, promotions, and more. This not only breaks silos but also enables alignment across all departments through standardized KPIs like ROI, ensuring a consistent and comparable evaluation method throughout your marketing ecosystem. This enables a unified measurement framework.

3.       Control for external factors

Sales can be influenced by weather, seasonality, competitors’ moves, or pricing. MMM adjusts for these effects to isolate the true contribution of marketing.

4.      Simulate and optimize

Once the analysis is complete, you can test various budget allocation scenarios—like increasing TV spend by 10% or halving your social media investment. By simulating these trade-offs before committing, you gain the clarity to optimize your media mix for both short-term results and long-term growth.

5.       Make MMM a living asset, not a static report

MMM is not a one-off project. To stay relevant, it should be updated quarterly or at least bi-annually, depending on your market dynamics.

💡 Pro tip: Choose a partner who combines statistical expertise with marketing acumen—someone who can translate results into decisions.

Proof: real results from real businesses

A global food brand, Bonduelle, leveraged Ekimetrics’ Marketing Mix Modeling platform to consolidate fragmented media data into a single source of truth. By centralizing access to the ROI of all media operations, adopting standardized KPIs across departments, and using dynamic simulation tools to evaluate various investment strategies in real time, Bonduelle accelerated its decision-making and improved cross-functional collaboration between marketing, finance, and commercial teams. Thanks to better-informed, performance-based resource allocation decisions—without increasing total media spend—the brand improved the efficiency and profitability of its campaigns. Meanwhile, a leading mobility brand used MMM to reallocate budget across the funnel, aligning investment to each stage’s contribution. The result? A 17% lift in media ROI and a projected total return of up to 30x on the initiative. The program is now scaling across six additional countries and business units.

Conclusion: it’s time to stop guessing

In a constrained environment, data-driven clarity isn’t just helpful—it’s your competitive edge. Marketing Mix Modeling empowers you to make better choices, prove impact, and build confidence with leadership.

✅ Key takeaways:

• Most companies underestimate the complexity of marketing ROI.
• MMM provides a structured, proven way to understand what works.
