Skeptical CFOs ask: "Would those sales have happened anyway?" Incrementality testing proves what marketing actually adds beyond organic growth.
What is Incrementality?
Incrementality measures the additional conversions caused by marketing that wouldn't have happened otherwise. It's the true contribution of your spend.
Testing Methods
- Holdout tests: Withhold marketing from a group and compare
- Geo experiments: Test in some regions, not others
- Matched market tests: Compare similar markets
