In short. Microsoft says enterprise Copilot web queries sent to Bing do not affect search ranking.
Definition: Microsoft's answer is no. Microsoft documents that web search queries generated by Microsoft Copilot and Microsoft Copilot Chat are sent to Bing with user and tenant identifiers removed, while Bing search ranking remains outside their effect.
Key facts
- When web search is enabled, Copilot can fetch information from Bing when web information helps ground a response, according to Microsoft's web search privacy documentation.
- Copilot parses a prompt, identifies terms that may benefit from web information, and sends Bing a generated search query based on those terms. The generated query is different from the user's original prompt.
- Microsoft states that generated queries sent to Bing leave search ranking, answer features such as rich captions, and social features such as autosuggest, trending, and zero input unchanged.
- The same documentation limits use of these queries to providing the service and excludes Bing improvement, advertising profiles, user tracking, and advertiser sharing.
- Microsoft's Copilot Chat privacy documentation says web grounding sends a few words generated from the prompt to Bing through a secure connection without user or tenant identifiers.
What query does enterprise Copilot send to Bing?
Web search is an optional feature. When it is enabled, Microsoft Copilot and Microsoft Copilot Chat may fetch information from Bing if information from the web helps produce a more grounded response. Copilot first identifies terms in the prompt where web information may help, then generates a separate query for Bing.
The query can be informed by a Microsoft 365 document when a user prompts Copilot inside a Microsoft 365 application while a relevant document is open, or when the user explicitly refers to a document. The generated query carries a theme from the document while the document remains in Microsoft 365. Microsoft gives this example for a prompt about an internal strategy document and a public company announcement:
Fabrikam clean energy policy announcements
The generated query excludes the entire prompt in ordinary cases, entire Microsoft 365 files, entire uploaded files, entire web pages or PDFs summarized in Microsoft Edge, and identifying information based on a Microsoft Entra ID. A very short prompt, such as "local weather", is an exception to the rule about the entire prompt.
What does Microsoft say about Bing ranking?
Microsoft's enterprise documentation says generated queries are sent to Bing with user and tenant identifiers removed. It then lists the outcomes these queries leave unchanged, including search ranking. The same page gives additional commitments for generated queries: Microsoft's rights are limited to what is needed to provide the service, and Bing improvement is excluded.
The Copilot Chat privacy page gives the same result in its description of web grounding. It says web search queries sent to Bing leave search ranking, answer or rich caption features, and social features such as autosuggest, trending, and zero input unchanged. It also says generated web search queries stay outside advertiser sharing.
This is a documented use restriction. The pages state the policy without presenting an independent measurement of ranking changes, so the answer concerns Microsoft's stated handling of enterprise Copilot queries.
Can an administrator inspect the generated query?
Microsoft documents query visibility for administrators. Web search query logging lets administrators search, audit, and perform eDiscovery on the exact queries Copilot derived from a user's prompt. Administrators can also view the web search terms beside the original prompt, response, and supporting resources in Microsoft Purview Data Security Posture Management for AI.
For users, web search query citations show the exact queries sent to Bing in the linked citation section of a Copilot response. Microsoft says this view is available only in Microsoft Copilot Chat, not in the Copilot pane inside Microsoft 365 applications such as Word or PowerPoint, and that the queries remain available in the chat thread for 24 hours.
