The Best-Kept Secret in Search Marketing
Microsoft shipped one of the most significant measurement tools in content marketing history, and the industry collectively shrugged. Sometime in late 2025, an “AI Performance” tab appeared in Bing Webmaster Tools. No announcement. No blog post. No conference keynote. It just showed up in the sidebar, labeled “(beta),” waiting for someone to notice.
I noticed. And what I found inside was the first real dataset on AI citation behavior that any search engine has ever exposed to publishers. The tab shows exactly how many times Microsoft Copilot cites your content, which queries triggered those citations, and how the volume trends over time.
For my domain, that data showed 98,800 AI citations across 576 grounding queries — numbers that completely changed how I think about content strategy. But when I talk to other marketers about it, the most common response is: “Wait, there’s an AI tab?”
This is a walkthrough. By the end, you’ll know where to find it, what it shows, and how to read the data.
Getting to the AI Performance Tab
Step 1: Verify your site with Bing Webmaster Tools. If you haven’t done this, start at bing.com/webmasters. You can verify using DNS, a meta tag, a CNAME record, or by importing from Google Search Console. The Google Search Console import is the fastest path — it takes about 30 seconds and automatically verifies all your Search Console properties in Bing.
Step 2: Navigate to your verified property. Once you’re in the dashboard, select the domain you want to analyze.
Step 3: Find the AI Performance tab. In the left sidebar, look under the “Performance” section. You’ll see the standard “Search Performance” tab (clicks and impressions from Bing search) and below it, “AI Performance (beta).” Click it.
If you don’t see the tab, there are two possible reasons: your site hasn’t been verified long enough for Bing to accumulate data, or your site hasn’t earned any Copilot citations yet. The tab may not appear until there’s data to show.
What You’ll See Inside
The AI Performance tab has three main data views:
Citation Count (total): This is the big number at the top. It shows the total number of times Copilot used your content as a grounding source in its responses. For context: my domain shows 98,800 total citations. This number represents actual instances where Copilot pulled information from my pages and embedded it in responses to real users.
Grounding Queries: Below the total count, you’ll see a list of the actual queries that triggered citations. These are natural language questions — not keywords. They show exactly what Copilot users asked when your content was cited. My top query is “claude ai pricing” at 16,500 citations. The query list is sorted by citation volume, showing your highest-impact content first.
Daily Trend Chart: A time-series chart showing daily citation volume. This is where you see growth patterns. My chart shows a clear acceleration: 672 daily citations at the start growing to 5,500 daily citations over 90 days. The shape of this curve tells you whether your citation authority is growing, stable, or declining.
Reading the Data: What the Numbers Mean
High citation count + few queries = concentrated authority. If you have thousands of citations but only 10-20 queries, your content is the dominant source for a small number of high-volume topics. This is a strong position — you own those topics in Copilot’s grounding index. My domain has this pattern: a few articles about Claude pricing and tools generate the bulk of citations.
Moderate citations + many queries = broad relevance. If you have hundreds of queries each generating modest citation counts, your domain is recognized as relevant across a wide topic area but isn’t dominant for any single query. This is a growth opportunity — identify the queries with the highest potential and create dedicated, optimized content for each.
Growing daily trend = citation flywheel. If your daily trend shows consistent growth, Copilot is developing increasing trust in your domain. This flywheel effect means each new citation makes your domain more eligible for additional queries. Protect this growth by keeping cited content accurate and current.
Flat or declining trend = stale content signal. If citations plateau or decline, it may indicate that your content is becoming outdated or that competitors have published more current versions. Check whether your most-cited pages have stale information — especially pricing, feature lists, or version numbers.
The Queries Are the Gold
The most valuable data in the AI Performance tab isn’t the citation count — it’s the grounding queries. These reveal exactly what enterprise workers are asking Copilot, which is intelligence you cannot get from any other tool.
Google Search Console shows you keywords — fragments that users type into a search bar. Bing’s grounding queries show you full natural language questions that users ask an AI assistant. The difference is significant:
A Google keyword might be: “claude ai pricing”
The Copilot grounding query is: “what is claude ai pricing in 2026 and how does it compare to openai”
The grounding query tells you the user’s full intent, their comparison frame, and their temporal context. This is richer intent data than any keyword tool provides, and it’s free, sitting in your Bing Webmaster Tools dashboard right now.
Use these queries to:
Identify content gaps. If users are asking questions that your content doesn’t fully answer, you know exactly what to add. A grounding query like “claude ai pricing vs openai pricing 2026 comparison” tells you to add an explicit comparison section to your pricing article.
Discover adjacent topics. The long tail of grounding queries often reveals related topics you haven’t covered. If you’re earning citations for “claude ai pricing” but also seeing queries about “claude api rate limits” and “claude team plan features,” those are content opportunities.
Understand your audience’s context. Grounding queries reveal the user’s situation. “What is the best AI coding tool for a team of 5” tells you the user is a tech lead making a purchasing decision. “How do I set up claude code on windows” tells you the user is a developer getting started. Each query paints a picture of who is consuming your content through Copilot.
What to Do With the Data
Once you’ve found and understood your AI citation data, here’s the action playbook:
Identify your citation pillars. Which pages earn the most citations? These are your highest-authority assets. Invest in keeping them accurate, current, and comprehensively structured. A $0.10 update to a page earning 1,000 daily citations is the highest-ROI content investment you can make.
Fill the gaps in your query coverage. Look at grounding queries that cite your content — are there related queries you’re not capturing? Build content for the gaps. If you earn citations for “claude ai pricing” but not “claude ai pricing for enterprise,” that’s a targeted content opportunity.
Structure for extraction. Look at which content formats earn the most citations. In my data, structured content — pricing tables, comparison matrices, step-by-step configurations — earns dramatically more citations than narrative-only content. Add extractable elements to your highest-value pages.
Set up a monitoring cadence. Check your AI Performance tab weekly. Track your daily citation trend and watch for inflection points. If a new article suddenly starts earning citations, double down on that topic. If an existing article’s citations start declining, check whether the content has become outdated.
Cross-reference with Search Performance. Compare your AI citation data with your traditional Bing search data in the same tool. Which pages earn citations but not clicks? Which earn clicks but not citations? This comparison reveals which content serves AI audiences vs human audiences — the foundation of platform-specific optimization.
Why This Matters Beyond Bing
Bing Webmaster Tools AI Performance is currently the only tool exposing AI citation data at this level of detail. Google Search Console doesn’t show AI Overview citation data. ChatGPT, Perplexity, and Claude don’t offer webmaster analytics dashboards.
But the data from Bing is a leading indicator for the entire AI citation landscape. Microsoft Copilot’s behavior reflects broader patterns in how AI engines consume and cite web content. The topics that earn Copilot citations are likely earning citations across other AI platforms too — you just can’t see the data yet.
By the time Google and other platforms expose their citation data (which I believe is inevitable as publisher demand grows), the early movers who used Bing’s data to develop platform-specific content strategies will have a compounding advantage. They’ll have built the citation authority, refined their content formats, and mapped their topic-platform fit while everyone else was waiting for better tools.
The tools aren’t perfect. They’re beta. But they’re real data about a real shift in how content gets consumed. And right now, almost nobody is using them.
Frequently Asked Questions
Is Bing Webmaster Tools free?
Yes. Bing Webmaster Tools is completely free to use. You only need to verify ownership of your domain, which can be done through DNS records, meta tags, or by importing your Google Search Console properties directly.
What if I don’t see the AI Performance tab?
The tab may not appear until your site has accumulated AI citation data. Verify your site, ensure it’s been indexed by Bing, and check back after a few weeks. Not all sites earn Copilot citations — the tab appears when there’s data to display.
Can I see which specific pages are being cited?
The current beta shows grounding queries and total citation counts. The page-level attribution is inferred through the queries — if a query about “claude ai pricing” cites your content, it’s almost certainly citing your Claude pricing page. Microsoft may add explicit page-level data as the tool matures.
How does Copilot decide which sites to cite?
Copilot uses Bing’s search index to find relevant content for grounding. The selection factors appear to include content relevance, structural quality, accuracy, domain authority, and trust signals built through consistent citation history. Well-structured, accurate, reference-grade content on topics matching Copilot user queries earns the most citations.
Should I optimize for Bing search to get more Copilot citations?
Bing indexation is a prerequisite for Copilot citations since Copilot uses Bing’s index. Ensure your site is indexed in Bing Webmaster Tools and that your key pages are crawlable. Beyond that, the most effective optimization for Copilot citations is creating structured, accurate, reference-grade content on topics that enterprise workers ask about.
