Independent research on AI search visibility
Who actually wins in AI search?✦
ChatGPT, Perplexity, and Gemini now answer the questions buyers used to Google, and they name only a handful of brands. I run the AI Search Visibility Index to track which ones get named across industries, publish the findings for free, and build free tools to measure it.

AI search, explained.
What is AI search visibility?
It’s how often AI assistants like ChatGPT, Perplexity and Gemini name your brand when someone asks them to recommend the best option in your category. More and more buyers start their research there instead of on Google.
Why does AI name some brands and not others?
AI builds its answers from the web sources it trusts most. If those sources don’t mention your brand, it won’t appear in the answer, no matter how well you rank on Google.
Is AI really replacing Google?
Google isn’t going away, but many buyers now ask AI first and get one direct answer instead of a page of links. You need to win both.
Can I influence what AI says about my brand?
Yes. By strengthening your content, making your brand clear and consistent across the web, and earning mentions from trusted sources, you can change whether AI recommends you. Knownful’s playbooks show you how.
