Most businesses are well-indexed in Google and invisible in Bing. That was a minor problem in 2020. In 2026, it means being absent from the knowledge retrieval stage of two of the fastest-growing AI recommendation surfaces on the planet.
The pub landlord who forgot to update his Google Maps listing
Imagine a pub landlord who spent six months renovating. New kitchen. New menu. Proper real ales. Somewhere genuinely worth going. Great local following, five-star TripAdvisor reviews. But he never updated the Google Maps listing. New opening hours. A phone number that goes nowhere.
People ask their phone assistant where to eat nearby. The pub either doesn’t appear or appears with wrong information. Potential customers — people actively looking for exactly what this landlord offers — never arrive. Not because the pub isn’t good. Because the information infrastructure behind the pub is broken. That is the situation most businesses are in with Bing right now. Except the stakes are considerably higher.
The number you need to understand
ChatGPT has 24.9 million monthly searches in the UK alone — up 83% year-on-year. Microsoft Copilot is at 1.5 million UK monthly searches, growing at 233% year-on-year. These are mainstream discovery surfaces used by the people who buy professional services, evaluate software vendors, and commission consultants.
Here is the part that changes everything: ChatGPT Search retrieves from Bing’s index. Microsoft Copilot retrieves from Bing’s index.
A business perfectly optimised for Google but absent from Bing’s index — not verified in Bing Webmaster Tools, not listed in Bing Places, schema not validated for Bing — is invisible at the knowledge retrieval stage for both platforms simultaneously. Most businesses have no idea this gap exists.
What Stage 2 actually means
In the AI Provider Selection Pipeline, Stage 2 is knowledge retrieval. Stage 4 is where recommendation eligibility is determined. But Stage 4 can only evaluate what Stage 2 retrieved. If you’re not in the index Stage 2 is pulling from, the downstream stages never consider you.
It is like applying for a job through a recruitment agency that has lost your CV. The interview panel might be perfectly open to hiring someone with your background. Your CV never reached the building. The job goes to someone else — not because they were better, but because they were findable. Bing is the index. For ChatGPT and Copilot, Bing is the front door.
The three things most businesses haven’t done
Bing Webmaster Tools. The equivalent of Google Search Console for Bing’s ecosystem — including, since February 2026, an AI Performance dashboard showing which of your pages are being used as grounding sources in Copilot responses. Most businesses have never set it up. The import from Google Search Console takes ten minutes.
Bing Places for Business. The local listing equivalent of Google Business Profile. When someone asks Copilot to recommend a solicitor or consultant, local results draw from Bing Places. If you’re not there, or the listing has an old address or wrong phone number, you are the pub landlord with the outdated listing.
Schema validated for Bing. Schema that passes Google’s Rich Results Test can still produce structured data errors in Bing’s pipeline. The February 2026 Bing Webmaster Guidelines specifically reference structured data as a factor in citation eligibility for Copilot responses.
None of this is complicated. None of it requires budget. The reason most businesses haven’t done it is that no one has pointed out clearly enough that it now matters more than almost anything else in the AI visibility toolkit.
The compounding problem
A business doing excellent content work appears in Google AI Overviews and feels its AI visibility strategy is working. Meanwhile a competitor — perhaps newer — has done the Bing infrastructure work. They appear in ChatGPT Search responses. They appear in Copilot responses for enterprise prospects asking their Windows Copilot assistant for recommendations. Both businesses think they have an AI visibility strategy. One has a Google AI visibility strategy. The other has a multi-platform one. Over twelve months, the second business appears on shortlists the first never sees.
What’s the point of a pretty website if no one can find it? The users and buyers haven’t gone anywhere — they’re sat inside LLMs asking more complex questions. Strong brands rank and dominate. That principle has not changed. You are who you hang with — authority signals from independent third parties outweigh anything you say about yourself. Bing’s index is building entity confidence through exactly this logic. The businesses building that infrastructure now are building the moat that will matter most as the landscape evolves.
