Timely Decisions: Rethink Your Marketing Measurement Strategy
The article argues that modern marketing measurement must drive action rather than postpone decisions. Attribution, incrementality testing and media mix modeling (MMM) each provide different signals; disagreement between them is common and should not be used as a pretext to pause optimization. Incrementality testing offers intra-time-period validation that complements MMM’s correlation-based insights. Durable growth comes from stacking smaller, validated improvements and deploying capital with sufficient confidence rather than waiting for perfect isolation of effects. The piece emphasizes balancing rigor and urgency: measurement should create confidence to make better bets more often, not absolute certainty. MarTech is owned by Semrush.

Key Takeaways & Evidence Grounding
- Attribution, incrementality testing and media mix modeling (MMM) are commonly used components of modern marketing measurement.
- Disagreement between different measurement approaches (attribution, incrementality, MMM) is typical and should not automatically halt decision-making.
- Incrementality testing provides intra-time-period validation and complements MMM, which is described as correlation-based.
- The author argues measurement's purpose is to create actionable confidence for budget and optimization decisions rather than perfect causal isolation.

Brands Ignore Measurement; Incrementality Solves Attribution
Trevor Testwuide, CEO and co-founder of Measured, published a sponsored op-ed arguing that modern platform-reported attribution (last-touch and platform claims) systematically misallocates marketing budgets. The piece recommends incrementality testing—using exposed vs. matched control groups (holdout tests)—to measure true causal lift and avoid paying repeatedly for demand a brand already had. It notes that retail media networks, social commerce, AI-driven discovery, and marketplaces exacerbate attribution errors, and explains that adopting incrementality requires organizational changes (incentives, agency pushback, revised KPIs) but yields clearer budget allocation and growth-focused investment. The article was published on Modern Retail and sponsored by Measured on 2026-07-02.
Rethinking Marketing ROI: Embrace Evidence-Based Measurement
The article argues that the era of easy measurement based on persistent third-party identifiers is over. It recommends a deterministic-first measurement system that combines randomized experiments (to establish causal ground truth) with calibrated probabilistic models such as marketing mix modeling (MMM) and multitouch attribution (MTA) to scale insights. Measurement should operate as a closed-loop cycle (Test → Calibrate → Allocate → Verify → Retest) run on a quarterly cadence with clear outcome metrics, consented first-party identifiers, ownership, and privacy-by-design using clean rooms. The piece also explains how AI can accelerate model recalibration and uncertainty detection without replacing deterministic experiments, and frames evidence-based measurement as critical for durable compliance and improved marketing ROI.
Measurement Must Improve to Unlock Marketing Budgets
Fabian Zimmermann, Managing Director and Head of Client Success Northern Europe & DACH at Incubeta, argues that marketing budgets underperform because measurement often confuses correlation with causal business impact. Dashboards and platform metrics (e.g., conversions, ROAS) can mislead by optimising within-channel signals without proving additional demand or profit. Zimmermann recommends a broader measurement architecture combining cross-channel measurement, incrementality tests, experiments and Marketing Mix Modeling (MMM) to attribute true incremental revenue and profitability. He cautions that AI amplifies existing problems when trained on fragmented or mis-specified goals and that simply increasing budgets will only scale inefficiency unless organisations identify real growth drivers.
