In this episode of the E-Commerce Playbook, Taylor Holiday and Richard Gaffin dig into the Measurement Roadmap—CTC’s framework for deciding what to test, when to test it, and why it matters. They unpack why incrementality testing is so crucial, the massive swings it can reveal in platform reporting, and how brands can use repeated tests to progressively “shrink the error bars” around decision-making.

From Meta’s 20% under-reporting benchmark to surprising Amazon lift results, Taylor shares concrete examples of how measurement gaps can change behavior, creative strategy, and even channel prioritization. The conversation highlights a hard but liberating truth: marketers don’t need perfect certainty—they need enough clarity to make confident decisions anchored in contribution margin.
