Carl Clasio, Decision Science Onboarding Manager, Prophet
For years, marketing measurement sat in an awkward space. It was useful, but not trusted. Necessary, but rarely loved. Teams pulled attribution reports because they had to, not because they believed they reflected how people actually made decisions.
But something is shifting. Across boardrooms and budget discussions, marketing mix modelling (MMM) is making a comeback. As marketers grapple with the limits of user-level attribution in privacy-constrained environments, MMM is re-emerging as the gold standard for causal inference across the full demand-generation funnel. And this time, it isn’t the slow, statistical relic marketers remember, it’s becoming one of the most important strategic tools in the CMO’s kit.
From reporting to real decision-making
The first wave of measurement was built for post-mortems. You ran a campaign, waited for the numbers, then braced for the verdict. It told you what happened after the fact, but offered little guidance on what to do next.
Today’s CMOs don’t have the luxury of hindsight. Budgets are under pressure while chasing performance goals that seem to keep moving further away. Boards want evidence and teams need direction, not just data.
The new generation of MMM is designed for planning rather than post-rationalising. Simulation and scenario testing allow marketers to explore what might happen if they shift spend, reduce activity, or double down on a channel.
It’s a measurement of foresight, not feedback.
For the past decade, measurement has been dominated by what was easy to track. If it produced a click, a view, or a cookie, it was included in the report. Everything else, especially offline, fell into the “hard to measure” bucket.
But the world has changed. Privacy rules, attribution instability, and channel fragmentation have forced marketers to revisit how all channels work together. MMM brings that holistic view back.
Offline channels like radio, outdoor, sponsorships and in-store activity reappear in the MMM model. Their indirect but often important influence on branded search, direct traffic, and sales becomes visible. And a new lens has been unlocked: “contribution”.
Now, instead of debating whether a channel “works”, teams can see the interplay across the full funnel, filling in the gaps of the “whys” and the “hows”.
A new kind of data literacy
What’s driving this resurgence isn’t just better modelling; it’s better interpretation. Modern decision intelligence tools make it easier for non-technical marketers to understand what’s happening during the purchase cycle, but the real shift is cultural.
Marketers are becoming fluent in data without becoming data scientists. They’re learning to interrogate results, question anomalies and challenge their own intuition – at the pace demanded by the current economic environment.
Curiosity matters more than technical ability.
The strongest conversations now happen between people who understand both the maths and the marketing. They don’t blindly accept outputs, but they don’t ignore them either. They use the data to spark debate, not end it.
Perhaps the most important element of this second coming is time. MMM tools don’t just measure immediate response – they capture the slower, cumulative effects of brand building.
In an environment obsessed with short-term performance metrics, this has been a wake-up call. Marketers are being reminded that brand work compounds. Creativity compounds. Consistency compounds. And measurement that reflects this gives CMOs the confidence to defend long-term investment.
Marketing measurement isn’t new. MMM isn’t new. But the reason marketers are turning back to them has changed.
This resurgence isn’t about proving the value of marketing, but improving it. When teams can see the full picture, they make better choices. When they can model the future, they plan more confidently. When they trust the data, they move faster.
This is the real second coming, not of models, but of meaningful measurement. The kind that helps marketers think more clearly, spend more wisely, and act with more conviction.
