What are Incrementality Testing Tools?
Incrementality testing tools help marketers measure the true causal impact of their advertising and growth campaigns by isolating what results would have happened without the marketing effort. These tools run controlled experiments—such as holdout groups, geo-testing, or matched-market tests—to determine whether an action actually drives incremental revenue, conversions, or lift. They cut through attribution noise by focusing on statistically valid comparisons rather than last-click or multi-touch modeling alone. Modern incrementality platforms use machine learning to automate experiment setup, validate sample sizes, and deliver reliable, real-time reporting. With these tools, teams can optimize budgets, improve ROI, and eliminate wasted ad spend with confidence.
