Book a meetingWhy we ran this study
ChatGPT went from roughly 400 million weekly users in early 2025 to around 900 million in the first quarter of 2026, establishing itself as a new dominant channel for search, information and decision-making. Understanding how it builds its answers is no longer an academic exercise: it is the foundation of any real GEO (Generative Engine Optimization) strategy.
