Case study

Microsoft Copilot cited our blog 4,000+ times in 90 days. Here is what it cited, and what it did not send.

Between July and September 2026, Microsoft Copilot cited pages on stellarcast.ai more than 4,000 times. The site was about three months old. On Google, the same pages mostly sat on page five or lower. And the citations sent almost no visitors.

We sell AI visibility measurement, so we measured ourselves. This is what the data shows, what the cited pages have in common, and why "being cited" and "getting traffic" turned out to be two different results for us.

Where the numbers come from

The short answer

Bing Webmaster Tools' AI Performance report (beta) counts how often Microsoft Copilot, AI-generated summaries in Bing and select partner integrations cite a site's pages. For stellarcast.ai it shows about 4,300 citations in the report window to 30 September 2026, with the first citations in the week of 20 July, holding at roughly 500-650 a week since mid-August, and spread across 22 cited pages.

Every figure in this post is first-party data we recorded on 3 October 2026: Bing Webmaster Tools' AI Performance report, which Microsoft introduced as a public preview, for Copilot citations, cited pages and grounding queries; Google Search Console, including its generative AI performance report, for rankings and AI Overviews and AI Mode impressions; and GA4 for visits.

Caveats we want up front, because a case study that hides them is not worth citing:

The timeline

Microsoft Copilot citations of stellarcast.ai per week, July to September 2026 Weekly citations from Bing Webmaster Tools AI Performance: 49 in the week of 20 July, none reported the week of 27 July, 110 the week of 3 August, then between 501 and 656 every week from 10 August to 21 September. The final bar covers only three days, 28 to 30 September, with 226. 0 200 400 600 49 20 Jul no data 27 Jul 110 3 Aug 564 10 Aug 567 17 Aug 656 24 Aug 576 31 Aug 535 7 Sep 501 14 Sep 502 21 Sep 226 28 Sep 3 days Copilot citations per week (week starting) Source: Bing Webmaster Tools, AI Performance (beta, sampled).

Citations started in late July, jumped in the week of 10 August and have held at roughly 500-650 a week since. Bing reported no data for the week of 27 July, which we show as a gap rather than a zero.

What Copilot cited

In our data, citations were extremely concentrated. Two pages earned about 80% of all citations:

PageCitations (3 months)
Best AI visibility tools (2026)~2,600
A competitor alternatives guide~880
AI search visibility in Norway~210
How to choose an AEO agency~70
Everything else (18 pages)~300 combined

Figures are rounded from Bing's page breakdown, which totals slightly less than the weekly series.

Most of our roughly 85 posts were never cited at all.

The questions behind those citations (Bing calls them grounding queries) were mostly buyer questions, not trivia. Where a percentage appears, it is our page's share of the citations Bing shows for those queries.

The gap: cited, but not ranked, and not clicked

The same months and the same pages produced three very different results:

SignalWhat we saw, Jul-Sep 2026
Copilot citations (Bing AI Performance)About 4,300
Google search ranking (Search Console)Most cited pages on page five or lower for their main query
Google AI Overviews / AI Mode (Search Console, beta)Impressions were a small fraction of Copilot's citation count (different metrics, so read as direction only)
Visits from AI assistants (GA4)A handful, all from ChatGPT
Visits identifiably from CopilotNone

Two things stand out.

  1. Copilot and Google disagreed. Our second most-cited page, a guide to alternatives for one competitor, ranks deep on Google for that competitor's name, on a results page few searchers are likely to reach. Copilot cited it about 880 times for the same topic. In our data, ranking and being cited behaved like separate results, which suggests the two systems may weigh different inputs.
  2. Citations were not traffic. One likely reason: Copilot can answer the question with the page's content, so the reader may have little need to click through. Some Copilot visits may arrive without a referrer and land in "Direct", so "none" is a floor, not an exact count. But nothing in our Direct traffic rose with the citations either.

If our AI visibility reporting had been built only on clicks and referral traffic, it would have shown us almost nothing.

What the cited pages have in common

We cannot prove causation from one site. These are patterns we saw, not a recipe:

What did not seem to matter: post count. About 80 posts went up in July and August; citations concentrated on a handful regardless.

How to measure this for your own site

  1. Bing Webmaster Tools > AI Performance. Free. Shows Copilot citations, cited pages and grounding queries. Verify your site if you have not.
  2. Search Console > Performance > Generative AI (beta). Google's AI Overviews and AI Mode impressions for your pages.
  3. GA4 AI Assistant channel for the clicks that do happen. For us it was small. Setup is in how to track ChatGPT and AI traffic in GA4.
  4. For ChatGPT, Perplexity and Gemini there is no webmaster report that we know of. The way to know is to ask them your buyers' questions, repeatedly, per market, and record who gets named and which pages get cited. That is what Stellarcast does; the method is in how we measure AI visibility.

We will add our own per-engine numbers for stellarcast.ai on those other engines to this post in an update.

Frequently asked questions

Can you see how often Microsoft Copilot cites you?

Yes. Bing Webmaster Tools has an AI Performance report (beta) that shows Copilot citations, the pages cited and the grounding queries behind them. Bing labels the data a sample, and a citation is an appearance in an answer, not a reader.

Do AI citations send traffic?

Rarely, in our data. About 4,300 Copilot citations in three months sent no visits we could attribute to Copilot, and AI assistants overall sent only a handful of visits, all from ChatGPT.

Does ranking on Google mean AI engines will cite you?

Not in our data. Our second most-cited page ranks deep on Google for its main query, and Copilot still cited it about 880 times.

Does FAQ schema get you cited?

It did not separate cited from uncited pages for us: every post has it, and most were never cited.
