Incrementality testing

Definition

Incrementality testing is a method used to determine the true impact of a marketing action by measuring the difference in outcomes between a group that received the marketing treatment and a control group that did not. This technique helps marketers understand which strategies are genuinely driving performance, rather than merely reflecting underlying trends or external factors. It connects deeply to optimizing media mix strategies, assessing the effectiveness of media strategies against business goals, and understanding cross-platform interactions.
