AI Referral Traffic Intelligence in North America

We believe in optimizing for the retrieval layer. But we got curious about who's actually sending the most clicks.
Our methodology draws directly from the work we do in Answer Engine Optimization (AEO), Generative Engine Optimization (GEO), and broader modern SEO services. These approaches help organizations understand traffic sources and optimize their strategies for AI platforms.
Updated weekly with multi-source validation and complete transparency.
