The Ecommerce Measurement Library: ROAS, Incrementality & Analytics Guides

Dashboards disagree, ROAS inflates, and half the metrics that matter never appear in any platform UI. This library indexes the measurement guides on Causality Engine — ROAS and spend efficiency, incrementality, customer economics, storefront analytics, benchmarks, and the calculators to run your own numbers.

For the attribution side of the problem — models, platforms, tracking, and fixes — see the companion Attribution Library. For the methodology underneath all of it, start with incrementality testing and marketing mix modeling.
