For most of the AI search era, marketers have been flying blind on one simple question: which of your pages do AI assistants actually cite? On June 16, 2026, Microsoft answered part of that question by expanding the AI Performance report in Bing Webmaster Tools with four new capabilities—Citation Share, Intents, Topics, and Compare. For anyone building an Answer Engine Optimization (AEO) or Generative Engine Optimization (GEO) program, this is the most concrete visibility data Microsoft has shipped yet. Here is what changed, what each metric means, and how to fold it into your 2026 strategy.
What is Bing Webmaster Tools Citation Share?
Citation Share shows your site’s percentage of all citations for a specific grounding query—the query an AI system runs against Bing’s index when it assembles an answer in Microsoft Copilot, Bing’s AI summaries, or partner AI experiences. If an answer about “residential solar installation” pulls from ten sources and two of them are yours, your citation share for that grounding query is 20%.
Microsoft is careful to call this an observational metric. It does not expose competitor domains, and it is not a measure of traffic or click share. But it is the first time any major platform has told publishers, in plain numbers, how often their content is the source an AI model leans on. That distinction matters: in AI search, being cited is the new ranking, and citation share is the closest thing we have to a rank-tracking signal for answer engines.
What changed in the June 16, 2026 Bing AI Performance update?
Bing first introduced the AI Performance report as a public preview back in February 2026, giving site owners impression and click data for AI-driven surfaces. The June 16 update layered on four features that turn raw counts into something you can actually act on:
- Citation Share — your percentage of total citations for a given grounding query.
- Intents — grounding queries classified into categories such as Informational, Commercial, and Research.
- Topics — related queries grouped into thematic clusters instead of an endless list of individual strings.
- Compare — an overlay that places a previous time period against the current view so you can see how citation activity is trending.
All four are rolling out in preview globally, so you do not need to be in a specific region to start exploring them. That is a meaningful contrast with Google, whose competing Search Console generative AI reports launched earlier in June 2026 to a limited set of UK-based site owners.
How do Intents, Topics, and Compare work together?
Individually these metrics are useful; together they form a workflow. Start with Topics to see which thematic clusters your site shows up for—say “solar panels,” “solar energy efficiency,” and “residential solar installation” all rolling up under one solar label. Then switch to Intents to learn whether AI assistants are citing you for informational questions, commercial comparisons, or deeper research queries. A site that wins informational citations but never commercial ones has a clear content gap to close.
Finally, Compare tells you whether your work is paying off. Overlay the last 30 days against the prior 30, or set custom ranges, and watch whether your citation share for a priority topic is climbing or slipping. That feedback loop—cluster, classify, then compare—is what separates an AEO program from one-off guesswork.
Why does Copilot visibility matter for AEO and GEO in 2026?
It is tempting to treat Bing as a rounding error and pour every hour into Google. That is a mistake in 2026. As of June 2026, ChatGPT leads generative AI chatbots with roughly 54.7% of worldwide web visits across the largest assistants, ahead of Google Gemini at 27.4% and Anthropic’s Claude at 8.2%. The common thread is that many of these assistants ground their answers in Bing’s index—Copilot is Bing-native, and other tools tap Bing’s commerce and web graph indirectly. When you optimize for Bing, you are often optimizing for Copilot at the source layer, and you gain a measurement surface for AI visibility that the larger ecosystem currently lacks.
Just as important, almost no brands are watching this data yet. That makes mid-2026 one of the cheapest windows to build an AEO advantage before the metric becomes mainstream and competitive bidding for attention catches up.
How to use citation share to improve your AEO strategy
Treat citation share as a diagnostic, not a vanity number. A practical starting routine: identify the three topics where you most want to be the cited source, record your current citation share and intent mix, then strengthen the pages behind them with clear, well-structured answers, factual specificity, and supporting data that an AI model can lift cleanly. Re-check with Compare every few weeks. If your share rises after you tighten a page’s structure and evidence, you have a repeatable playbook; if it falls, you know exactly where to dig.
This is the same discipline that good search engine optimization has always demanded—answer the question better than anyone else—now pointed at answer engines instead of blue links. If you want help turning Bing’s new citation data into a content roadmap that also serves Google AI Overviews and ChatGPT, that is exactly the kind of work we do at Rosh Media.
Bing vs. Google: should you track both?
Yes—and they are not redundant. Google’s Search Console generative AI reports currently show impressions only, with no citation-share equivalent and limited regional availability. Bing’s AI Performance report gives you citation share, intent, topic clustering, and period-over-period comparison globally, in preview, today. The two platforms surface different slices of the same AI search reality, and the citations rarely overlap. Wiring both into your monthly reporting is the fastest way to understand where your content already earns AI trust and where it still needs to.
The takeaway from June 2026 is straightforward: AI visibility is finally measurable, and Bing got there first with a metric—citation share—that maps directly to how answer engines work. Start watching it now, and you will be optimizing with data while your competitors are still guessing.
