He also makes the case for evidence-based attribution strategies and explains why incremental lift studies and MMMs often mislead more than they reveal.
In this episode:
  • The 3 Types of Measurement: Empirical attribution, statistical modeling (MMM), and causal testing, and why only one is useful for most brands.
  • Why MMM is Misunderstood: How fast MMMs use “priors” (aka  assumptions) to feed marketers the results they want to see, and the dangers of confirmation bias in model-driven decisions.
  • The Limits of Incrementality Testing: Why confidence intervals make most claims about exact lift misleading.
  • The Case for First-Click Attribution: Why tracking the first click (plus robust identity graph) offers a clearer view of what’s actually acquiring new customers. “Everyone complains about last-click attribution. But nobody’s asking why we don’t talk about first-click.”
  • Re-Attribution Using Self-Reported Data: How SegmentStream pairs self-reported attribution with actual behavior to uncover awareness channels like YouTube, podcasts, and word-of-mouth.
