Most published AI-search statistics are borrowed, US-centric, and already stale. cloro monitors ChatGPT, Perplexity, Gemini, Copilot, Google AI Overview, AI Mode, and Google Search continuously — so these studies come from first-party measurement, not estimates. Each one states its sample, method, and date, and is free to cite.
Where AI Overviews appear, the trigger rate runs from 67% (Germany) to 93% (US); ChatGPT backs its answers with ~12 sources to Gemini's ~1.
Domains that block GPTBot are cited far less by ChatGPT — median citations-per-appearance 0.003 vs 0.417 — and the effect is engine-specific.
Commercial and voice queries trigger an AI Overview ~98% of the time; local restaurant queries just ~3%.
Across cloro's monitored SERPs, AI Overviews appear on ~70% and People Also Ask on ~92%.
The #1 organic result changes on 31.7% of consecutive days.
Gemini cites a source on just 41% of answers vs 97%+ for ChatGPT and Copilot; YouTube, Google, and Reddit are the most-cited domains in AI search; and Google AI Mode draws 58% of its citations from only 10 sources.
