Microsoft Copilot Search Optimization: A Bing-First Guide

Microsoft Copilot search optimization means getting your pages indexed in Bing, keeping them eligible for Copilot answers and writing them so Copilot can quote them. Copilot builds its answers from Bing search results. That makes Bing indexing, the NOCACHE and NOARCHIVE directives, and clear, well-structured pages the main levers. You can measure the results in Bing Webmaster Tools.

None of this involves a secret Copilot trick. Below is what Microsoft actually documents, what it doesn't, and the order to work in.

How does Microsoft Copilot choose which websites to cite?

Copilot grounds its answers in web results from Bing. Your page has to be in Bing's index and come back for the query Copilot sends. Then it can be used and linked as a source. Microsoft doesn't publish a ranking formula for which result gets cited.

Microsoft describes this retrieval step most concretely in its Copilot Studio web search documentation. The agent turns the user's question into "a brief, focused keyword query" and sends it to Bing. Bing returns page titles, snippets and citations, and the agent writes a summarized answer that links to the cited websites. The same page says the sites searched are "public websites indexed by Bing."

For consumer search, Microsoft's Copilot Search announcement (April 2025) says Copilot Search "cites its sources prominently." It also says it inline links "the entire sentence or passage within the responses" and shows a list of every link used to build the answer.

In practice, you're optimizing for two steps:

1. Retrieval. Bing must have crawled and indexed the page, and the page must match the short, rewritten query Copilot sends.
2. Selection. Out of the results it gets back, Copilot picks passages to quote. Microsoft gives content advice for this step (covered below) but no list of weights.

Is Copilot SEO different from Bing SEO?

Mostly it isn't. Copilot sits on top of Bing's crawling and indexing, so a page that Bing can't crawl, render or index can't be cited. The Copilot-specific parts are a few meta directives, the way you shape passages, and the citation reporting.

In February 2026, Microsoft rewrote parts of the Bing Webmaster Guidelines. As Search Engine Journal reported, the guidelines now define generative engine optimization as "focused on content eligibility for grounding and reference in AI responses." They also say GEO doesn't guarantee citations, just as SEO doesn't guarantee rankings. The same update added AI-specific abuse rules. Content engineered to trigger AI citations now falls under the keyword stuffing rules, and prompt injection aimed at Bing or Copilot has its own section.

The table below shows how the work splits.

If you already work on ChatGPT, many of these steps will look familiar. Our guide on how to get your website cited by ChatGPT covers OpenAI's side. For every engine on one page, see the AI search optimization checklist.

Which robots.txt and meta tags affect Copilot?

Your robots.txt rules for bingbot decide whether Bing can crawl the page at all. After that, page-level directives decide how Copilot may use it. NOINDEX keeps the page out entirely. NOARCHIVE keeps it out of Copilot answers. NOCACHE limits Copilot to the URL, title and snippet.

Microsoft first set out these controls in its September 2023 announcement for Bing Chat, the product that later became Copilot:

• No directive: the page may appear in chat answers, and its content may be used to train Microsoft's generative AI foundation models.
• NOCACHE: the page may appear in answers, but Microsoft "will only display URL/Snippet/Title." Only those fields may be used for training.
• NOARCHIVE: the page "will not be included in Bing Chat answers, not be linked to in the answers" and won't be used for training.
• Both tags: Bing applies NOCACHE, the less restrictive of the two.

Pages with NOCACHE or NOARCHIVE still show up in Bing's regular search results. The updated guidelines, as summarized by Search Engine Journal, advise against NOCACHE on content you want Copilot to cite in depth. They also warn that nosnippet and data-nosnippet may limit citation quality.

<!-- Excluded from Copilot answers and from training; still in Bing search -->
<meta name="bingbot" content="noarchive">

<!-- Copilot may cite it, but only URL, title and snippet -->
<meta name="bingbot" content="nocache">

The trade-off is real. Microsoft ties the same directives to model training. With no directive, your content can be used for training. With NOARCHIVE, it isn't used for training, but you also lose Copilot citations. Decide this page by page, and check that a plugin or CDN template hasn't added noarchive across the whole site by accident. Our robots.txt guide explains the crawl side.

The Microsoft pages we reviewed don't describe a separate Copilot crawler with its own robots.txt token, the way OpenAI has OAI-SearchBot. Treat bingbot access as the switch for crawling.

How do you get your site indexed in Bing for Copilot?

Verify the site in Bing Webmaster Tools, submit an XML sitemap and use IndexNow to report changed URLs. Then make sure your key content is in the HTML, not only added later by JavaScript. Copilot can only quote what Bing has indexed, and only the version of the page Bing holds.

Work through these steps in order:

1. Verify the site in Bing Webmaster Tools. You can import the site from Google Search Console if it's already verified there.
2. Check that bingbot isn't blocked. Look at robots.txt, firewall rules and bot-protection settings. Rules that only allowlist Googlebot are a common reason a site never shows up in Bing.
3. Submit your sitemap and fix the errors Bing reports.
4. Set up IndexNow. Under the IndexNow protocol, you host a key file at the site root and send changed URLs, up to 10,000 per POST. Each submission "will be automatically shared with all other participating search engines." In its AI Performance announcement, Microsoft recommends IndexNow so AI systems reference "the most current version of a page."
5. Check rendering. If prices, product details or answers appear only after scripts run, compare the raw HTML with the rendered page. Our guide to JavaScript SEO rendering problems shows how to test this.

How should you write pages that Copilot can quote?

Write passages that answer one question completely in a few sentences. Use clear headings, put facts in tables, back claims with evidence and keep the page up to date. Microsoft lists these points itself as ways publishers can improve their citations.

The AI Performance announcement gives this list of improvements:

• Build subject expertise and depth.
• Use "clear headings, tables, and FAQ sections."
• Support claims with evidence and data.
• Keep content current and accurate.
• Keep text, images and video consistent with each other.

Here's how that looks on a typical small-business page:

• Answer first. Under a heading like "How long does a boiler service take?", put the answer in the first sentence: "About 45–60 minutes for a standard gas boiler." Then explain what changes it.
• Self-contained passages. Copilot links a whole sentence or passage, so each one should still make sense when it's quoted alone. Name the subject instead of writing "it" or "this."
• Tables for specs and comparisons. Opening hours, service areas, plan differences and dimensions are easier to pull from a table than from a paragraph.
• Visible dates and sources. Show "Updated November 2026" and link to your evidence.
• Match Copilot's short queries. Copilot shortens questions into keyword queries, so use the plain terms your customers would type, such as "boiler service cost London." Brand slogans don't match those queries.

On-page FAQ sections are fine for Copilot. Just don't expect them to earn FAQ rich results in Google, because Google has retired that result type. Microsoft hasn't documented any Copilot benefit from specific schema types. Organization markup with sameAs links still helps search engines tie your site to your brand profiles.

How do you measure Copilot citations?

Open the AI Performance report in Bing Webmaster Tools. It shows how often your pages are cited in Copilot and Bing's AI summaries, which URLs are cited, and the grounding queries that pulled them in. It doesn't show where in the answer you appear or how many clicks you get.

Microsoft launched AI Performance as a public preview on February 10, 2026. It covers Microsoft Copilot, AI-generated summaries in Bing and select partner integrations. The report includes:

Microsoft states that the report doesn't show "placement, presentation, ranking, authority, or the role of any page within an individual answer." Use it to spot trends and gaps. It won't score individual pages. A practical routine:

1. Export the grounding queries every month.
2. Find important queries where your best page isn't the one being cited, then improve or consolidate that page.
3. Compare cited URLs with Bing's Search Performance data and your analytics referrals from copilot.microsoft.com and bing.com.

What should you fix first?

Fix eligibility before content. If bingbot is blocked, the page isn't indexed or a stray NOARCHIVE is present, no rewrite will help. Once Bing can index and use the page, improve the passages that answer your customers' main questions, then track the results.

A sensible order:

1. Blockers: bingbot denied in robots.txt or the firewall, NOINDEX or NOARCHIVE where you don't want them, a site not verified in Bing.
2. Depth limits: NOCACHE, nosnippet or data-nosnippet on pages you want cited, and key content that only appears after JavaScript runs.
3. Freshness: sitemap errors, no IndexNow, outdated facts.
4. Quotability: answer-first sections, tables and evidence on your highest-value pages.
5. Entity clarity: consistent business name, address and descriptions, plus Organization markup with sameAs links.

To check the robots and visibility items on your own site, request a free audit. Its GEO checks review AI crawler access in robots.txt, snippet controls, text that only appears after JavaScript runs, and Organization/sameAs markup. You can see how the findings are presented in the sample report.

Key takeaways

• Copilot grounds its answers in Bing's index, so Bing crawling and indexing come first.
• NOARCHIVE removes a page from Copilot answers and NOCACHE limits Copilot to the URL, title and snippet. Neither affects regular Bing results.
• Microsoft's own advice is clear headings, tables, evidence and fresh content. Use IndexNow to keep the indexed version current.
• Measure with the AI Performance report in Bing Webmaster Tools. It counts citations but doesn't show placement or clicks.
• Microsoft publishes no Copilot ranking factors. Treat any "Copilot score" with suspicion.
