Copilot does not read the open web live. It works from a chain: Bingbot crawls a page into the Bing index, Copilot's retrieval step runs several machine-written searches against that index, and a language model writes an answer that cites the pages it used. A publisher can be cited dozens of times in a day without a single reader arriving, because the answer is complete on the Copilot screen. That makes Copilot a citation channel first and a traffic channel a distant second, and it changes what a publisher should measure, control and negotiate.
What is Microsoft Copilot?
Microsoft Copilot is a family of AI assistants rather than one product. It runs as a standalone assistant, inside Windows, inside Microsoft Edge, inside Microsoft 365 applications, and as an AI answer layer in Bing search. For publishers, the surfaces that matter are the ones that answer web questions from the Bing index: the consumer assistant and the AI answers shown in Bing results.
Copilot is the successor to Bing Chat, which Microsoft launched in early 2023. The underlying dependency has not changed: web answers are grounded in Bing's index, so Bing's view of your site decides whether Copilot can use it.
Microsoft does not publish a clean Copilot audience figure for the consumer assistant. On its 28 October 2026 results it disclosed no Copilot user count, saying only that Copilot daily users rose nearly 50% quarter on quarter and more than five times year on year. The enterprise product is better documented: Microsoft said in April 2026 that Microsoft 365 Copilot had passed 20 million paid seats. Enterprise seats are not web-search behaviour, so that number says little about how much publisher content is being consumed.
How do Bingbot, the Bing index and Copilot fit together?
The pipeline determines what a publisher can influence. Three steps matter:
- Crawl and index. Bingbot fetches pages and adds them to the Bing index. If Bingbot cannot reach a page, Copilot cannot cite it.
- Retrieval. When a user asks a question, Copilot generates its own search queries and pulls candidate pages. Microsoft's reporting calls these grounding queries.
- Synthesis. A model writes the answer and attaches citations to the sources it relied on.
This matters for the usual robots.txt question. Blocking Bingbot removes a site from Bing search and from Copilot answers together. There is no separate Copilot crawler to block on its own, so the choice is all of Bing or none of it. Publishers who want finer control have to use page-level directives, covered below.
How often does Copilot send readers back to publishers?
Rarely, on the evidence available, though that evidence is thin and comes from individual sites rather than an industry benchmark.
Digital agency Whole Whale reported that its content was cited 48,000 times across 34 pages in Bing's AI tools over roughly three months, and that it recorded 14 clicks from Copilot. That is a click-through rate of about 0.03%. The same agency reported that its Bing organic traffic fell by about three quarters from November 2025. Whole Whale notes the caveats itself: it is a single site, the organic drop cannot be attributed to AI answers alone, and the click figure comes from cross-referencing separate analytics.
A second case study points the same way. Search Influence recorded 19,717 Copilot citations across 86 of its pages between 12 November 2025 and 10 February 2026. One page produced 69% of them, and the top four pages produced 90%. Citations then fell sharply, from a daily peak of 5,804 on 7 December to an average of 34 a day in February, a drop of about 97%, for reasons the authors could not confirm. Their analysis also suggests raw citation counts overstate the number of conversations, because a single conversation can generate three to five citation events.
Two lessons follow. Citation volume is concentrated in a handful of pages, and it can disappear quickly. Neither case study is a benchmark, but both show why citation counts should never be reported as traffic.
What does Bing's AI Performance report show?
Bing Webmaster Tools added an AI Performance report in public preview in February 2026. It shows how often a site's pages are cited in Copilot answers, which pages are cited, and which grounding queries triggered the citations. Practical Ecommerce reported in June 2026 that the report had been extended with query intent, query topic, the average number of unique pages cited per day, and citation share, with sorting and spreadsheet export.
It still has no click or visit data, does not split by channel, and does not say which AI partners surfaced the citation. Search Influence also noted at launch that there was no API and no view of competitors cited for the same queries. Publishers need to join the report to their own analytics to see what, if anything, the citations produced.
The grounding queries are the most useful part. They are keyword-dense, machine-written rewrites of the user's question, so they show how Copilot decomposes a topic and which sub-questions a site is being retrieved for.
What controls do publishers have over Copilot?
Publishers have three levers, and only one of them is fine-grained.
Bingbot access. The robots.txt rules for Bingbot decide whether a page is in the index at all. Blocking it is an all-or-nothing decision across Bing search and Copilot.
Page-level directives. In September 2023 Microsoft introduced NOCACHE and NOARCHIVE for Bing Chat. NOCACHE allows content to appear in answers but limits what is shown to the URL, title and snippet. NOARCHIVE keeps the content out of Bing Chat answers and out of Microsoft's generative model training, while the page remains in ordinary Bing results. Microsoft's February 2026 webmaster guidance reportedly applies the same logic to Copilot grounding and also covers NOSNIPPET and a data-snippet attribute for choosing citable text; that account reaches us through a secondary outlet, so check Microsoft's current documentation before relying on the detail.
Freshness signals. IndexNow, an open protocol supported by Bing, lets a site push URL changes to participating search engines when it publishes or updates. Because Copilot retrieves from the Bing index, faster indexing shortens the gap between a correction or update and the answer reflecting it.
Does Microsoft pay publishers for Copilot?
Not by default. Standard Bing crawling and indexing carries no payment, and Copilot answers draw on that index.
Microsoft's route to payment is the Publisher Content Marketplace, announced on 3 February 2026 as a pilot. Publishers set licensing and usage terms, AI builders license content for specific grounding uses, and payment is described as based on delivered value, with usage reporting. The launch partners were The Associated Press, Business Insider, Condé Nast, Hearst Magazines, People Inc, USA TODAY Co. and Vox Media, with Yahoo as the first external buyer. Digiday reported in February that, according to an anonymous source, payment follows a CPM model. Microsoft says publishers of any size can register interest, and the marketplace remains a pilot. Pricing has not been published.
Advertising in Copilot is a separate matter. Microsoft Advertising's documentation says eligible campaigns are automatically opted in to appear in Copilot, ads are created from existing campaign assets, and there are no Copilot-specific metrics yet. The documentation says nothing about sharing that revenue with the publishers whose content grounds the answer.
What should publishers do about Copilot?
Start with measurement. Verify the site in Bing Webmaster Tools, export the AI Performance report monthly, and compare cited pages against Bing referrals in your own analytics. Treat the ratio of citations to visits as the key figure, because it shows whether Copilot is working as a discovery channel or only as a consumption layer.
Then decide on access deliberately. For most publishers, blocking Bingbot is a blunt instrument with a real cost, since it removes Bing search visibility too. Page-level directives suit publishers with premium or paid content that they want out of answers but still indexable. Finally, register interest in the Publisher Content Marketplace if licensing is a goal, and keep the terms of any deal separate from the question of how your pages are crawled.
Publishers who want to understand what AI agents are doing on their own sites, across Copilot and every other assistant, need server-side visibility rather than platform reports. That is the part of the stack a CDN-edge approach, such as the one blankspace uses, is designed to cover.
Frequently asked questions
Is Microsoft Copilot the same as Bing Chat?
Copilot is the successor to Bing Chat, which Microsoft launched in early 2023 and later rebranded. Microsoft has extended the capability into Windows, Edge, Microsoft 365 and Bing search results under the Copilot name, so it is now a family of surfaces. For publishers, the relevant ones are those that answer web questions from the Bing index.
Does blocking Bingbot stop Copilot using my content?
Yes, because Bingbot feeds the index that Copilot retrieves from. The cost is that the pages also disappear from Bing search. There is no separate Copilot crawler to block on its own, so publishers wanting a narrower approach should look at NOARCHIVE and NOCACHE instead.
Does Microsoft pay publishers whose content Copilot uses?
Not through standard crawling. Payment is available through the Publisher Content Marketplace, a pilot launched on 3 February 2026 with seven named publishers and Yahoo as a buyer. Microsoft says publishers of any size can register interest, but terms and pricing are not public.
Can I see how often Copilot cites my pages?
Yes. The AI Performance report in Bing Webmaster Tools shows citations, cited pages and grounding queries, with sorting and export. It does not show clicks, so visits have to be measured in your own analytics.
Will Copilot bring traffic back to publishers?
The published evidence suggests not at scale. Whole Whale recorded 14 clicks from 48,000 citations and Search Influence saw citations collapse within weeks. These are single-site cases, not benchmarks, but they support planning around citation visibility and the smaller, high-intent visits that do arrive, rather than a return to earlier Bing referral volumes.
