ChatGPT generally makes use of Google to search out data on the internet—it doesn’t simply use Bing or its personal search engine. (Opposite to well-liked perception.)
Abhishek Iyer, a former Google Engineer who now builds AI search engine marketing brokers, proved that ChatGPT makes use of Google when he:
- Created a webpage round a fictional time period
- Made this webpage accessible solely to Google
- Requested ChatGPT in regards to the fictional time period
- Acquired a response with an AI quotation linking to his webpage
ChatGPT might have solely accessed this webpage by way of Google.
Leigh McKenzie, Head of Progress at Backlinko, repeated Abhishek’s experiment with completely different variations of ChatGPT.
His outcomes recommend that ChatGPT Plus makes use of Google, however the free model doesn’t.Â
This could possibly be as a result of sourcing data from Google is costlier for OpenAI than sourcing data from its personal net index or Bing.
Why Do Individuals Suppose ChatGPT Solely Makes use of Bing?
Many individuals suppose ChatGPT makes use of Bing as its solely third-party search supplier as a result of OpenAI (ChatGPT’s proprietor) has a partnership with Microsoft (Bing’s proprietor). Plus, earlier variations of ChatGPT included a “Browse with Bing” characteristic.Â
In my expertise, ChatGPT itself claims to make use of solely Bing—not Google—for net shopping.

ChatGPT makes this declare even when it sources data from the net, suggesting that this perception is the consensus on-line:

Nevertheless, Microsoft’s Yusuf Mehdi solely says Bing is the default search supplier for ChatGPT:
I’m happy to announce we’re bringing Bing to ChatGPT because the default search expertise.
OpenAI says it makes use of Bing as its sole third-party search supplier for Enterprise and Edu workspaces:
At present, the one third-party search supplier we use for Enterprise and Edu workspaces is Bing, and we won’t add different search suppliers until we offer discover to you of this variation.
I can’t discover proof of OpenAI claiming that different ChatGPT workspaces use solely Bing.
In documentation for ChatGPT search, Bing and Shopify are the one named third-party suppliers.Â

However OpenAI additionally says that “ChatGPT search generally companions with different search suppliers.”
How Typically Does ChatGPT Use Google?
Abhishek and Leigh’s experiments show that ChatGPT makes use of Google no less than generally. We don’t know precisely how typically or in what circumstances ChatGPT makes use of Google as an alternative of Bing. Â
My speculation is that ChatGPT makes use of Google as a backup when Bing offers unsatisfactory outcomes.Â
In Abhishek and Leigh’s experiments, Bing couldn’t present passable outcomes as a result of the topically distinctive pages had been solely listed in Google.Â
I additionally suppose that ChatGPT solely resorts to Google for paying customers as a result of Google API entry is comparatively costly for OpenAI.
Why Does It Matter that ChatGPT Makes use of Google?
ChatGPT utilizing Google issues in advertising as a result of it means your web site’s Google visibility might play a direct function in its ChatGPT visibility.
This strengthens the concept conventional search engine marketing (search engine marketing) is a necessary facet of generative engine optimization (GEO).
