In short. Microsoft Copilot can use Bing search to answer questions with source links, while Bing documents content controls and citation reporting for websites.

Definition: Microsoft Copilot is Microsoft's AI assistant. It can answer questions using web search, with links to the sources used in its responses.

As of 17 October 2026, Microsoft's product comparison describes a free version for web-based tasks and subscription versions integrated into Microsoft apps.

Key facts

Microsoft's product comparison says Copilot uses large language models, systems that generate responses to questions or prompts.
Microsoft's web search guide explains that Copilot Chat sends a shortened query to Bing and uses the results in its answer.
Bing's content control documentation describes data-nosnippet, an HTML attribute that excludes selected page sections from snippets and AI summaries while keeping them indexed.
Bing's AI Performance announcement describes citation reporting across Microsoft Copilot, Bing AI summaries and selected partner integrations.

How does Copilot use web sources?

Microsoft's web search guide describes the process for Copilot Chat. Copilot constructs a Bing query from a few words in a prompt or an uploaded file, then uses retrieved web content to inform the response. The full prompt or file becomes the query only when it is already very short; Microsoft gives “New York City weather” as an example.

The same guide identifies a Sources button below responses that use web search. It opens the sources used and the exact query sent to Bing. This provides a way to inspect which search query supports an answer about a business or its services.

Which page content can appear in answers?

Bing's data-nosnippet announcement documents a control for selected sections of a page. The attribute belongs in the page's HTML, the markup that structures its content. The following minimal example follows Bing's documented syntax:

<div data-nosnippet>Subscriber content</div>

Bing says marked content remains indexed and available for ranking, while being excluded from snippets and AI summaries. Its examples of uses include subscriber material, expired promotions and legal boilerplate. The control applies to Bing-supported search and AI experiences, including Copilot experiences powered by Bing.

How can a website measure Copilot citations?

Bing's AI Performance announcement describes reports for individual URLs and citation trends over time. A citation is a source reference displayed in an AI answer. The report combines supported AI experiences, so its totals cover a broader scope than Copilot alone. Grounding queries, the retrieval phrases associated with cited content, represent a sample of citation activity.

Bing's expanded reporting announcement describes preview features called Intents, Topics, Citation Share and Compare. Intents classifies query purposes; Topics groups related retrieval queries. Citation Share measures the percentage of citations attributed to a site among all sites for the same grounding query. Compare overlays an earlier reporting period to show changes over time. These views provide context for recorded citations when assessing a website's presence in AI answers.
