Fractl study — vendor-published (author is a Fractl co-founder)
AI models agree on brand visibility only 11% of the time
A Fractl analysis of 4,320 AI responses to 96 industry prompts across GPT-4o, Gemini 2.5 Flash and Claude Sonnet 4.6 — drawn from roughly 8,500 unique brand references — found only 11% of brands were named by all three models, while 77% appeared in just one, per Search Engine Land. The study also compared results against Ahrefs authority metrics; in the travel category, Booking.com led with 285 AI mentions ahead of Airbnb (227) and Expedia (215).
Why it matters: Visibility fragments by model, so a brand optimizing for one AI answer engine has no guarantee of showing up in another — 'AI search' isn't a single channel to win.
