How does Copilot pick sources in Bing, and cite you?

Copilot is Microsoft's AI assistant. In this guide we mean its answer inside Bing search: the paragraph it writes when your customer searches on Bing, with links beside it to the pages it built that answer on. Those links are what we call a citation in an AI answer.

Microsoft puts Bing search and Copilot under one set of guidelines for site owners. It says Bing and Copilot search experiences rely on the same core crawling, indexing and ranking foundation as traditional search, so the road to a Copilot answer starts in Bing's index and nowhere else.

If you are asking «هل copilot يدعم اللغة العربية» ("does Copilot support Arabic?"), the answer is yes: Arabic is on Microsoft's list of languages Copilot takes questions in and answers in, on the support page Microsoft last updated in September 2026. But the language of the question does not decide the sources. The sources are what Bing finds in its index.

This guide is part of the eight AI engines we measure in Arabic, where Copilot sits among the three search surfaces. What applies to Gemini alone is in how Gemini chooses its sources in Arabic, and cites you.

Because a page Bing does not know gives Copilot nothing to cite. Bing's guidelines say a noindex tag keeps a page out of Bing search and out of Copilot experiences alike, so before you change a single sentence, make sure your important pages are in Bing's index at all.

Start by adding your site to Bing Webmaster Tools, Bing's dashboard for site owners. It lets you import the sites you have already verified in Google Search Console instead of proving ownership again. Then submit your sitemap and check which of your pages Bing knows and which it does not.

Bing's guidelines ask for four things that touch almost every site. Here they are in our words:

• A clean sitemap: canonical URLs only, matching the site as it is today, with deleted or redirected pages removed promptly and a last-modified date for every page.
• Bingbot not blocked in robots.txt: blocking it takes your pages out of the index Copilot answers from.
• Content that does not hide behind JavaScript: the guidelines warn against hiding critical content behind client-side rendering, and say content that cannot be rendered reliably may not be indexed or selected for grounding.
• One address per page: a page served from many URLs weakens Bing's confidence in picking one of them as a source. The fix is one canonical URL and permanent redirects from the rest.

IndexNow is a way for your site to tell the search engines that take part in it about every page that is added, updated or deleted, on the day it happens, instead of waiting for each engine's crawler to come by. IndexNow's own documentation says the URLs one participating engine receives are shared automatically with the others.

A site proves the request is its own with a small text file at its root that holds a key. IndexNow's documentation also says that an accepted request only means the engine received the URL, not that it will crawl or index it. It is a notice, not a guarantee.

Bing's guidelines tie IndexNow to Copilot directly. They ask you to notify Bing when a URL is added, its content is updated or it is removed, and say timely notifications help Bing refresh its index and reduce outdated or incorrect URL references in Copilot responses. That matters to any business whose prices or opening hours change from one season to the next.

On our own site, tasadr.ai, every new deploy has sent the URLs it changed to IndexNow since 11 October 2026. When we edit a page, Bing hears about it the day it goes live, without waiting for its crawler. We do not claim that this alone makes Copilot cite us: the notice speeds up the reading, it does not decide the choice.

Four tags you place on a page, each with a different effect on Copilot. This is what Bing's guidelines say about each one, as we read them on 17 October 2026. A theme or a plugin can add them without the site owner noticing.

It tells you where your site is cited in Microsoft's AI answers. Bing launched it on 10 February 2026 inside Bing Webmaster Tools, covering Microsoft Copilot, AI-generated summaries in Bing and some partner integrations; the short definition is in what is Bing's AI Performance report? It has five parts:

• Total citations: how often your site was shown as a source in answers during the period, without saying where in the answer your link sat.
• Average cited pages: how many different pages of your site are shown as sources per day, on average.
• Grounding queries: a sample of the phrases the AI searched with when it retrieved your content.
• Page-level citations: which of your pages are cited more than the rest, which is where your work starts.
• Trend over time: how the number of citations moves from one period to the next.

A page that stands on its own and answers one question in its first lines, with clear names and dated facts. Bing's guidelines say the same in other words: facts and definitions should be explicit on the page, and an important statement should not depend on something said on another page.

• One topic per page. Bing says pages focused on one primary topic are more likely to be selected for grounding, and advises that the title, headings and content share one intent.
• The answer at the top, with no long introduction before the topic, as the guidelines ask.
• One name for your business everywhere. Bing asks for clear, consistent names for organisations, products and places, and says this improves citation accuracy. Write your Arabic and Latin names the same way on every page; the idea is explained in what is an entity in search?
• Questions and answers written on the page, not inside a tab or a menu that opens on a click. Microsoft's guide to writing content advises against hiding important answers there, because AI systems may not render hidden content.
• Facts as text, not images. A price inside an image, or a table that exists only inside a PDF, is harder for these systems to read accurately, as Microsoft's own guide says.
• Honest updates. Bing asks you to update content when facts change, remove or revise what is outdated, and tell it through IndexNow when you add, change or delete a page.

Two ways, each completing the other. The first is the AI Performance report, which tells you how often your site was cited, on which page and for which phrase. The second is asking Bing your customers' questions in their own words, reading each answer to the end, and opening its links to see which of them are yours.

Ask the same question on different days before you judge: one answer is a snapshot, not a trend. The manual method, step by step, is in how to check whether your site leads ChatGPT and Gemini answers, and it works for Copilot as well.

At Tasadr (تصدَّر) we measure Copilot as a search surface, Microsoft's answer inside Bing search. We ask it your customers' questions in Arabic and in their dialect, and record for each answer whether your site was cited, mentioned without a link or absent, and who was cited instead. The Business plan measures it when it is among its engines, up to 8 chosen with you, and every plan is on Tasadr pricing.

Nobody can guarantee that Copilot will cite you. Bing's own guidelines say that SEO does not guarantee rankings or traffic, and that optimising for AI answers (GEO) does not guarantee grounding or citations in AI experiences.

The figures in this guide come from one check on 14 October 2026 and from Microsoft's pages as we read them on 17 October 2026. Bing changes its reports and guidelines from time to time; if anything here changes, we correct it and date the correction. What we can do is measure regularly and show you who was cited instead of you, and why their page was cited and yours was not.
