Here's a quirk that trips up a lot of businesses: when ChatGPT looks something up on the live web, it isn't using Google behind the scenes. Through its partnership with Microsoft, it leans on Bing — Microsoft's search engine. That one fact has a practical consequence.
If Bing can't find you, ChatGPT struggles to
Short version: Bing is the back door into ChatGPT (and Microsoft's own Copilot).
Most businesses pour everything into Google and never think about Bing. But if your site isn't in Bing's catalog of pages, ChatGPT often can't pull you in when someone asks. It's a blind spot precisely because so few people check it.
Everyone optimizes for Google. Almost no one checks whether Bing can even see them — and that's the door into ChatGPT.
The fix is small and free
Short version: Make sure Microsoft has your site on file.
Microsoft offers a free tool (Bing Webmaster Tools) where you can submit your website so Bing knows it exists and keeps it current. It takes a few minutes and is separate from any Bing maps or business listing. It's one of the cheapest, most-overlooked moves for ChatGPT visibility.
Where this comes from: Microsoft and OpenAI's partnership is public, and 2026 analyses found ChatGPT's live-web citations closely track Bing's results. Figures are directional; we're describing how the plumbing works.
