With media spread across more channels and tighter privacy constraints, brands are struggling to see what's really driving business impact. Think with Google reports that marketing mix models (MMMs)—once complex and costly—are now smarter, faster, and capable of merging with incrementality testing and attribution for more granular, cross-channel insights. For leaders focused on digital strategy and growth, 2025 is the year to master measurement.
What's Changed
Modern MMMs can provide real-time insights and respond to changes in the economy and demand. Google's open-source Meridian, with access to Google and YouTube data, is set for broader rollout, offering a transparent and robust measurement option. The key is aligning on KPIs, mapping media spend, and building an experiments calendar—measurement is an ongoing process, not a one-off project. Our strategy consulting and digital marketing work often starts with clarity on what to measure and how.
Why It Matters Now
Without a clear view of cross-channel performance, teams either overspend on underperforming channels or underinvest in winners. MMMs help cut through the noise so you can optimise for business outcomes, not just last-click metrics. Integrating this mindset into your planning supports the kind of propel, transform, optimize cycle that sustains long-term growth.
Conclusion
Prioritise measurement in 2025: align on KPIs, map spend, and adopt or refine MMM-based thinking. For more on how we help brands measure and grow, see our blog and services.
