Why Incrementality Experiments
Understand what’s really driving impact
Incrementality experiments identify the marketing activities causing business outcomes by comparing impacts from groups exposed to your marketing against groups who were not.
Use incrementality experiments to reveal the true causal impact of every dollar, cut wasted spend, and invest with confidence in the channels that actually drive incremental growth.
