How to Prove Marketing Works in 90 Days

The operating manual for migrating from correlation-based measurement to a causal stack. Moving from correlation-based measurement to a causal stack isn’t a tooling decision.

The Framework

The pattern holds across industries, company sizes, and starting points.
Five moves, in this order.

Diagnose: Find the Gap

Audit your current stack honestly. Find the gap between what you report and what actually drives revenue.

Anchor: Get One Real Number

Run your first incrementality test on a channel that matters. Make causal truth a fact your organization has seen, not a slide it’s been shown.

Triangulate: Build One Source of Truth

Reconcile causal MMM, incrementality, and incrementality-adjusted attribution into one number per channel.
