You’ve got great reviews. Your competitors don’t outrank you on Google. Yet when people ask ChatGPT for recommendations in your industry, your brand never appears. The answer might surprise you: Bing shapes ChatGPT recommendations, not Google.
A recent case study tested this theory with 68 identical prompts asking ChatGPT for the best hotels in New York City. The results show exactly why some brands dominate AI recommendations while others stay invisible.
How Bing Shapes ChatGPT Recommendations More Than Google Rankings
The researchers picked two boutique hotels with similar ratings but vastly different ChatGPT visibility. The Baccarat Hotel appeared in only 1.5% of responses. The Fifth Avenue Hotel appeared 13 times across the same 68 trials.
Both hotels had identical Google review ratings of 4.6 stars. The Baccarat actually had more reviews and longer market presence. Yet it stayed nearly invisible to ChatGPT users.
The difference wasn’t reputation or quality. It was search engine visibility in the wrong place.
When ChatGPT answers questions, it sends multiple search queries behind the scenes. For hotel recommendations, these included phrases like “best luxury hotels in NYC” and “top boutique hotels New York City recommendations.”
The researchers tracked where these queries led in both Google and Bing. Google results favored the Baccarat Hotel. It appeared higher on lists, got mentioned more often, and generally dominated the search results that most SEO professionals track.
But Bing told a different story. The Fifth Avenue Hotel dominated five of the eight most frequently appearing URLs in Bing results for the same queries. When the same Forbes article ranked high in both search engines, the Bing version didn’t mention the Baccarat at all.
Why Your Google SEO Success Doesn’t Guarantee AI Visibility
This creates a blind spot for most brands. You can win Google rankings and still lose in ChatGPT recommendations.
The Baccarat Hotel won three of the top 10 most frequently appearing pages in Google search results for hotel-related queries. The Fifth Avenue Hotel won only two. Based on Google alone, you’d expect the Baccarat to perform better in ChatGPT.
The opposite happened because Bing shapes ChatGPT recommendations through the query fanouts that happen during response generation.
Previous research by Seer Interactive found that 87% of ChatGPT citations align with Bing’s top results. This case study extends that finding beyond citations to actual brand mentions in responses.
Brand mentions matter more than citations for most businesses. When ChatGPT says “The Fifth Avenue Hotel consistently makes top NYC lists from travel editors,” that recommendation sticks with users. Most people won’t click through citations, but they remember the brands ChatGPT highlighted.
The Manual Process That Revealed This Pattern
The researchers ran the same prompt 68 times and extracted every query fanout, citation, and mention. They compared Google and Bing results for 25 unique search queries that ChatGPT generated internally.
This manual process took weeks for just one brand in one category. They had to track which hotels appeared where, compare sentiment and positioning across dozens of articles, and map patterns between search rankings and AI mentions.
The work revealed something most brands miss: winning Google doesn’t mean winning AI search. In verticals dominated by third-party content like travel recommendations, your visibility depends on which search engine the AI models actually use for their research.
AI Mentions automates this entire process. Instead of manually running dozens of prompts and tracking competitor visibility, you can monitor which brands appear in ChatGPT outputs and identify patterns that affect your own mention frequency. The platform reveals which specific queries trigger competitor recommendations instead of yours, showing exactly where your content gaps prevent AI citation eligibility.
Why the Details Matter More Than General SEO Strategy
The case study found two different Forbes articles ranking for similar hotel queries. One dominated Google results. Another dominated Bing and ChatGPT citations.
The Baccarat Hotel appeared prominently in Google’s Forbes article but wasn’t mentioned at all in Bing’s version. Getting into the Google article provided no ChatGPT visibility boost. Getting into the Bing article could change everything.
This level of detail matters because most brands approach digital PR too broadly. “Getting coverage in Forbes” isn’t specific enough when different Forbes articles serve different search engines.
You need to know which specific articles and which specific search engines drive AI recommendations in your vertical. This requires tracking Bing results with the same intensity most brands reserve for Google.
What This Means for Your Brand’s AI Visibility Strategy
The research shows that training data alone doesn’t determine ChatGPT brand mentions. The Baccarat Hotel had better fundamentals than its competitor but lacked presence in the Bing results that actually fed into ChatGPT’s recommendations.
If your brand isn’t appearing in ChatGPT responses, check your Bing visibility for the queries that matter to your business. Look beyond your own website rankings to third-party content that mentions your competitors but not you.
The pattern appears to work like this: brands rank in Bing search results, ChatGPT fanouts pull in those Bing pages, then ChatGPT synthesizes both training data and current Bing results to generate brand mentions.
AI Mentions tracks this process automatically, showing which competitor messaging AI assistants have absorbed and testing whether your content updates actually improve mention frequency before you invest in full production. For brands losing visibility to AI-recommended competitors, AI Mentions diagnoses exactly which content gaps prevent your citations and mentions across major AI platforms.
