SEO for Bing Copilot: The Under-Covered AI Search Surface

Everyone in the AEO space is chasing ChatGPT and Perplexity citations right now. Almost nobody is writing about Microsoft Copilot, and that gap is exactly why it's worth your attention. Microsoft disclosed on its fiscal year 2026 first-quarter earnings call that its family of Copilots has crossed 150 million monthly active users across work, coding, security, health and consumer use cases. That's a real audience, sitting inside Windows, Edge and Microsoft 365, and most brands have done nothing to optimize for it.

I think the reason Copilot gets ignored is simple: it doesn't feel like a destination the way chatgpt.com or perplexity.ai does. You don't "go to" Copilot. It's already open in your taskbar, your Edge sidebar, or your Word document, answering questions you didn't think of as a "search." That ambient placement is precisely what makes it worth optimizing for. If your product gets recommended inside a Word doc someone is drafting, or an Edge sidebar query someone runs mid-task, you're showing up at a moment competitors optimizing only for chatgpt.com never reach.

How Bing Copilot actually sources its answers

Copilot's answer engine and Bing are not two separate systems that happen to share a name. When Copilot needs current, factual, or citable information, it pulls candidate pages from Bing's own web index, reads them, and generates a cited response from that pool. If a page isn't in Bing's index, it isn't in the pool Copilot draws from, no matter how well the page would have answered the question.

That single fact should reorder your priorities. Most AEO advice tells you to write clearer, more liftable content. That still matters here, but it's step two. Step one is unglamorous: does Bing actually know your page exists, and does it rank your page as a credible source for the queries you care about? A page with excellent structure and zero presence in Bing's index isn't invisible to Copilot by bad luck. It's invisible because it was never a candidate.

The IndexNow shortcut most sites still skip

IndexNow is a free, open protocol that Microsoft co-developed, and it's the fastest lever you have here. Instead of waiting for Bing's crawler to rediscover a new or updated page on its own schedule, IndexNow lets you ping Bing (and other adopters, including Yandex) the moment you publish or change a page. Bing, LinkedIn, eBay, GitHub and a long list of CMS platforms and SEO tools already support it. Setup is genuinely small: most WordPress sites can turn it on through a plugin like All in One SEO, and Bing Webmaster Tools shows you submission status under Reports & Data > IndexNow once it's running.

If you're publishing pricing pages, product updates, or comparison content that changes often, IndexNow closes the gap between "we shipped this" and "Copilot could actually cite this" from days down to hours. For anything time-sensitive, that's the difference between being the source and being the also-ran that shows up next week after the query has moved on.

Where Copilot actually shows up, beyond bing.com

Part of why brands underrate Copilot is that they're picturing a single chat window at copilot.microsoft.com. The real distribution footprint is wider than that, and each surface carries a different intent.

• Windows taskbar and sidebar. Microsoft has been rolling a docked Copilot experience into Windows 11, and confirmed a dedicated "Ask Copilot" feature landing in the taskbar and Start menu around mid-2026, aimed squarely at Microsoft 365 users. That's a query surface sitting on every managed enterprise laptop, not something a user had to seek out.
• Edge's built-in sidebar. Copilot is wired directly into Edge, so a question typed while someone is already reading a competitor's page, a review site, or your own pricing page gets answered without a tab switch. That's a genuinely different moment than someone opening a fresh ChatGPT tab to research a purchase.
• Microsoft 365 apps. Word, Excel, Outlook and Teams all carry Copilot integrations, which means a question about "vendors that do X" can surface inside a document someone is actually drafting for a decision, not in a separate research phase.
• Bing.com itself. The classic search-plus-chat hybrid, where Copilot answers sit alongside or above traditional blue links.

None of this shows up in a webmaster's day-to-day checklist because it doesn't map to a URL you can visit and test. But it's exactly why "Copilot has a smaller market share than ChatGPT" undersells how it's actually used. A lot of that usage is task-embedded, close to a buying or vendor-selection decision, and invisible to anyone only watching chatgpt.com traffic referrals.

Bing Webmaster Tools is your only real feedback loop

This is the part almost nobody talks about, and it's the actual reason I'd call Bing Copilot under-covered rather than just underused. Bing Webmaster Tools shipped a genuine citation-tracking feature, and it's free.

Microsoft's own webmaster blog announced the AI Performance report in public preview on February 10, 2026. It tracks citations across Microsoft Copilot, Bing's AI-generated summaries, and select partner integrations, and it surfaces:

• Total citations: how many times your pages showed up as a cited source in AI-generated answers over a chosen period.
• Average cited pages: the daily average count of unique URLs from your site referenced in those answers.
• Grounding queries: sample phrasing of the actual queries that triggered your citations.
• Page-level citation activity: which specific URLs get pulled most often.
• Visibility trends: a timeline so you can see whether citation activity is climbing or fading.

Microsoft then expanded the report on June 16, 2026, adding four capabilities worth knowing about specifically:

• Intents: buckets your grounding queries into categories like Informational, Commercial, Navigational, Research and Local, so you can see what kind of demand is actually citing you.
• Topics: clusters related queries into themes (Microsoft's own example groups "solar panels," "solar energy efficiency" and "residential solar installation" under one "Solar Energy" topic) instead of leaving you to eyeball a list of raw keywords.
• Citation Share: the percentage of citations your site earns out of all citations shown for the same grounding query, explicitly framed by Microsoft as observational data, not a competitive leaderboard.
• Compare: overlays a previous period on the current one so you can measure whether a content change actually moved citation volume.

Compare that to what you get for free from OpenAI or Perplexity on your own citation performance: nothing. No dashboard, no query-level breakdown, no first-party data at all. You're stuck inferring visibility from third-party trackers or brand-mention monitoring tools. Bing Webmaster Tools is handing you the one AI search surface where the platform owner tells you, directly and for free, exactly which pages got cited and for which queries. That alone should move it up your priority list, independent of Copilot's raw usage numbers.

What actually moves the needle for Copilot citations

Since Copilot inherits Bing's index and Bing's ranking signals as its retrieval layer, most of the fundamentals you already know from technical SEO still apply, just with an AI answer layer bolted on top.

• Get indexed and rank in classic Bing first. Verify your site in Bing Webmaster Tools, submit an XML sitemap, and check that your robots.txt doesn't accidentally block Bingbot. None of the rest matters if this step fails.
• Turn on IndexNow for anything that changes. Pricing, inventory, comparison tables, FAQ answers. The faster Bing sees the update, the sooner Copilot can cite the current version instead of a stale cached one.
• Write the liftable sentence, not just the good paragraph. Copilot pulls short, self-contained factual statements into its answers. A clear one-sentence definition or a direct number ("Plan X costs $49/month and includes Y") gets lifted more cleanly than a claim buried three sentences into a paragraph.
• Add structured data where it's genuinely true. Product, FAQ, and Organization schema give the retrieval layer unambiguous facts to pull from, rather than making it infer structure from prose.
• Check the AI Performance report monthly, not once. Grounding queries and Citation Share change as your content and competitors' content change. Treat it the way you'd treat a rank tracker, not a one-time audit.

Bing Copilot next to the other AI search surfaces

Here's roughly how Copilot compares to the platforms most brands are already chasing, based on what's publicly documented as of this writing.

Market share estimates put Copilot well behind ChatGPT and Gemini in raw chatbot usage. That's real, and it's a fair reason not to make Copilot your first priority if you're choosing where to spend limited hours. But "smaller audience" and "under-covered opportunity" aren't the same claim. Fewer brands are actively optimizing for Copilot citations than for ChatGPT ones, which means the same amount of work buys you more relative visibility here than it does in a surface every competitor is already crawling for.

Should you actually prioritize this right now

My honest take: if you're a 5-10 person marketing team choosing between chasing ChatGPT citations and setting up IndexNow plus checking Bing Webmaster Tools once a month, do the Bing work first. It costs almost nothing, most of it is a one-time setup, and you get a genuine feedback loop instead of guessing. If you're already running full AEO tracking across multiple platforms, add Copilot as one more surface in that same dashboard rather than treating it as a separate project.

What I wouldn't do is treat Copilot optimization as a separate discipline from your existing SEO and AEO work. It isn't one. Since Copilot's retrieval layer is Bing's index, everything you do to rank well in Google's AI-driven results mostly transfers here with a different indexing target. The unique work is small and specific: verify in Bing Webmaster Tools, wire up IndexNow, and actually read the AI Performance report instead of letting it sit unopened.

Common questions about Bing Copilot SEO

Does Bing Copilot use the same ranking factors as classic Bing search?

Largely yes, because Copilot's retrieval step pulls from the same underlying Bing index. If a page can't rank in Bing's normal results for a query, it's unlikely to be a candidate Copilot cites for that same query either. The generation layer on top adds its own preference for clear, self-contained factual statements, but the gate you have to clear first is still classic Bing indexing and ranking.

Is IndexNow only useful for Bing?

No. IndexNow is a shared protocol, so a single ping notifies every participating search engine at once, including Yandex, rather than requiring separate submissions. Bing is the largest adopter and the one most relevant to Copilot specifically, which is why it gets the attention here.

How is the AI Performance report different from a third-party AI visibility tracker?

Third-party trackers estimate your visibility by running sample prompts and checking whether you show up in the responses. Bing's AI Performance report is first-party data straight from Microsoft's own logs, so it isn't a simulation. The tradeoff is that it only covers Microsoft's own surfaces (Copilot, Bing AI summaries, partner integrations), so you'd still want a broader tracker if you also need visibility into ChatGPT or Perplexity.

Does blocking Bingbot affect anything besides Bing search rankings?

Yes. Because Copilot's retrieval layer depends on Bing's index, blocking Bingbot in robots.txt removes you from both classic Bing search and Copilot's citation pool at the same time. Check this before assuming a robots.txt rule is only affecting one surface.
