What is Microsoft Copilot?

The short answer

Microsoft Copilot is Microsoft's AI assistant. It runs on large language models, and you'll bump into it all over the place: inside Windows, in the Edge sidebar, on Bing, and across Microsoft 365 apps like Word, Excel, and Outlook. Ask it a question, draft an email, summarize a doc, whatever. It's the same brand stretched across a lot of surfaces.

Here's the part that matters for anyone trying to get found. When Copilot answers a question about the live web, it doesn't just make something up from memory. It grounds the answer in Bing.

How Copilot finds its answers

The mechanic is simpler than it sounds. Copilot takes your prompt, turns it into a short Bing search query, runs that search, reads the results, and then writes an answer based on what came back. Then it shows a Sources button so you can see which pages it actually used. Microsoft spells this out in their own docs on how web search works in Copilot.

So Copilot is basically Bing wearing a friendlier face. The model writes the prose, but Bing decides which pages get a seat at the table.

That has a clean, almost boring implication: if you're not visible in Bing, you're probably not getting cited by Copilot. There's no separate secret index. It's Bing all the way down.

What this means for getting cited

The path to a Copilot citation runs straight through Bing, and Bing visibility comes from the usual suspects:

• Get indexed in Bing. Sounds obvious. Plenty of sites that rank fine in Google are barely in Bing. Submit a sitemap through Bing Webmaster Tools and check you're actually in there.
• Answer the question fast. Copilot lifts clean, direct passages. Put the answer in the first couple of sentences of a section, not buried in paragraph nine.
• Be crawlable. If your robots.txt blocks the crawlers, you remove yourself from the running. Worth a read: AI crawlers and robots.txt, plus the AI crawler glossary entry for the quick version.
• Earn credibility. Sourced facts, clear expertise, and corroboration from other sites all help, the same way they help with any AI citation.

None of this is a cheat code. It's the same content hygiene that wins across AI search, just pointed at Bing instead of Google. We go deeper in how to get cited by Microsoft Copilot.

Copilot vs the other AI engines

People lump all the AI assistants together, but they don't fetch the web the same way. Quick map:

The takeaway: optimizing for Copilot is mostly optimizing for Bing, which is a different muscle than optimizing for Google. If you want the wider landscape, we wrote up the AI search engines and how they differ.

Where AI Citation Monitor fits

Straight answer: AI Citation Monitor tracks Copilot as a live engine, via Bing Copilot Search. It's one of the five engines we measure.

What we track today is five engines: ChatGPT, Perplexity, Gemini, Google AI Overviews, and Microsoft Copilot. For each one you get a citation rate and visibility score with confidence intervals (because pretending we have perfect certainty would be a lie), competitor share of voice, source tracking that shows which pages get pulled, and prescriptive fixes that tell you what to change. There's a free instant check if you just want to see where you stand.

Because Copilot leans on Bing, the content habits that win there (clear answers, sourced claims, crawlable pages) are the same ones that get you cited across the other engines we watch. Improving your standing on one tends to move you in the right direction on the rest.

The bottom line

Microsoft Copilot is Microsoft's AI assistant, and its web answers are grounded in Bing with a visible Sources panel. Want Copilot to cite you? Win at Bing: get indexed, answer fast, stay crawlable, build credibility. And since we track Copilot live via Bing Copilot Search, you can watch that work pay off.
