Short answer: only Google’s own AI uses Google’s search results. The others can’t — Google doesn’t license its index — so each major AI platform pulls from a different source. Here’s the breakdown, and it matters a lot for what you’re selling:
Google Gemini and AI Overviews — yes, these are the exception. Google AI Overviews are powered by Gemini and pull from Google’s existing organic search index, and Gemini weighs Google Business Profile data more heavily than the other platforms, which matters for local businesses — and its AI Overviews respond well to schema markup. So traditional Google SEO still feeds Google’s AI directly.
ChatGPT — no Google at all. ChatGPT’s real-time web search runs on Bing, which most SEO teams miss — if a site isn’t indexed in Bing Webmaster Tools, it’s invisible to ChatGPT’s citation engine. ChatGPT also favors established editorial sources, with Wikipedia and reference media making up a large share of its citations.
Perplexity — runs its own crawler and index, and heavily prioritizes recency — content under 30 days old earns roughly 3.2x more citations, with community and forum content like Reddit showing up far more often than in the other platforms.
Two findings from the research that are directly relevant to your pitch:
Ranking in Google no longer guarantees AI visibility — even in Google’s own AI. In mid-2025, roughly 76% of pages cited in AI Overviews also ranked in the top 10 organic results for the same query; by early 2026, separate research placed that figure at approximately 38%, with other data putting it around 17%. Traditional organic ranking is becoming a weaker predictor of AI Overview citation, not a stronger one.
The platforms barely overlap. An analysis of 680 million citations found only 11% of domains are cited by both ChatGPT and Perplexity — a business visible in one engine can be completely absent from another.
The practical takeaway for your articles and sales conversations: a client can’t win AI search by optimizing for Google alone anymore. They need Google indexing (for Gemini/AI Overviews), Bing indexing (for ChatGPT), crawlable original content with fresh dates (for Perplexity), and third-party mentions across multiple sources — which, conveniently, is exactly the multi-platform, always-publishing case your network model makes. The 30-day-freshness stat and the 11%-overlap stat are both strong proof points worth working into future pieces.
