What is incrementality testing?
A controlled experiment, such as a geo (matched market) test, that measures how many sales your advertising actually causes compared with what would have happened anyway. The result, incremental ROAS, is a better guide for budgets than platform-reported ROAS.
What does the free incrementality app do?
It runs entirely in your browser. You paste or upload a CSV of a KPI by market and date. The planner finds matched control markets and estimates how long a test should run. The analyzer estimates incremental lift with a synthetic-control style model, a chart, and a confidence interval. Recommendations are rule-based, not an LLM. Nothing is sent to a server.
What is GEO, and how is it different from SEO?
Generative Engine Optimization (GEO), also called Answer Engine Optimization (AEO), is the work of getting your brand mentioned, cited and described accurately in AI-generated answers from tools like ChatGPT, Gemini, Perplexity, Grok, Claude and Google AI Overviews. SEO competes for a ranked link; GEO competes to be the source an assistant quotes or recommends. We run them together.
Do you replace my team or my current agency?
Neither, necessarily. Many companies keep their team and use us to add measurement, AI capability or a specific channel. We recommend whatever structure gets the best result, even if that means a smaller engagement.
Try the app, or talk through a live test.
Use the free planner on your own data, or email us if you want help designing the test or connecting this to ad accounts later.
