Surprisingly, not much — at least not for ChatGPT. ChatGPT and Microsoft Copilot can't read your Google reviews or Google Business Profile directly; they draw on Bing Places, Yelp, RealSelf, and the open web. So a clinic with hundreds of glowing Google reviews can still be invisible in ChatGPT. Reviews do matter for AI — but it's the reviews on the sources each engine actually reads.
Here's the counterintuitive part most owners miss: a strong Google review profile is the thing you've worked hardest on, but Google keeps that review and Business-Profile data inside its own ecosystem. ChatGPT and Copilot are powered by Bing and the open web, so they largely don't see your Google reviews at all. That's why a clinic can be the top-rated spot on Google Maps and still never get named when a patient asks ChatGPT for a recommendation — the assistant most patients now reach for first.
Reviews still matter for AI — but per engine, on different sources. ChatGPT leans on Bing Places plus the third-party sites it trusts in aesthetics (Yelp, RealSelf, Healthgrades). Google's own AI uses Google's signals. Perplexity searches the live web each time, which includes those same directories. What earns the citation is consistent business details and genuine reviews across the sources each engine actually reads — not a pile of reviews on one platform the AI can't access.
So the move isn't to stop collecting Google reviews — they still win the Google map pack — it's to stop assuming they cover you everywhere. Claim and complete your Bing Places listing (a 15-minute job almost no clinic does, and it's a primary ChatGPT source), keep your Yelp/RealSelf/Healthgrades profiles accurate and consistent, and earn real reviews there too. Our free AI-visibility audit shows where you currently show up across ChatGPT, Perplexity, Gemini, and Google's AI — and which sources are leaving you out.
