Microsoft Copilot and Bing Webmaster data: the AI visibility channel people forget

Ask a marketing team which AI engines they track and you'll hear ChatGPT, Perplexity, maybe Google. Copilot comes up late, if at all. That's understandable, since it rarely appears in conversations about growth. It's also a gap, because Microsoft Copilot is tied to the Bing ecosystem and that ecosystem has its own indexing and its own webmaster data.

Here's what we do for clients to cover it without spending much time.

Why Copilot needs its own look

Each engine pulls from its own mix of sources. Copilot's connection to Bing means the state of your site in Bing matters in a way it doesn't for other assistants. A page that Google indexes well but Bing hasn't picked up is a page Copilot may never see.

That's a testable hypothesis, and testing it is cheap. We start with Bing Webmaster Tools, which is free.

Step 1: verify the site in Bing Webmaster Tools

If you haven't verified your domain, do it first. Without it you can't see how Bing treats your pages. Once verified, you can submit your sitemap and see indexing status and search performance.

Look for pages that Google has indexed and Bing hasn't. Check for crawl errors. Check that your robots.txt isn't turning Bingbot away. These are dull checks and they catch real problems.

Step 2: check what gets crawled and when

Your server or CDN logs show which bots hit your pages. Bing's crawler is one; AI assistants may use others. Keep a clear picture of what you allow. Our guide on AI crawler access covers robots.txt rules and CDN settings, and the general point holds here: block deliberately, never by accident.

Promptwatch's Agent Analytics logs AI crawlers in real time with IP verification, filters out spoofed user agents, and shows errors with failure explanations. Its integrations catalog covers crawler logs through Cloudflare, AWS CloudFront, Fastly, Vercel, Netlify, Akamai, Google Cloud CDN, custom HTTP, and a WordPress plugin. Pick the one that matches your stack.

Step 3: ask Copilot the real questions

Run your prompt panel through Copilot. As with every engine, record whether you're named, how you're described and which sources are shown. Keep Copilot results separate from the others.

Expect differences. A brand that does well in ChatGPT Search can be absent in Copilot, and the reverse. Those differences are information. If you're missing in Copilot only, the cause is likely something Bing-specific: indexing, a source Bing weights that others don't, or a gap in third-party coverage.

Step 4: overlay Bing data on AI data

Looking at Bing Webmaster in one tab and your AI tracker in another gets tedious. Promptwatch's Search Insights brings Google Search Console and Bing Webmaster traffic, including Microsoft Copilot, into the same view as AI crawls and citations.

That overlay answers questions that are otherwise awkward:

Which pages get Bing traffic and no AI citations?
Which pages get AI citations and little search traffic?
Did a drop in crawls precede a drop in citations?

The fact sheet for the product says the Search Insights feature joins Search Console and Bing Webmaster data to AI crawls and citations. We use it as a way to find the pages where the pieces disagree, since disagreement is where the work is.

Step 5: improve what Bing and Copilot can use

The fixes are mostly ordinary and they help every engine:

Make sure key pages are indexed in Bing and listed in your sitemap.
State facts plainly on the page, in sentences an engine can lift.
Keep titles and headings descriptive.
Fix crawl errors and slow or broken pages.
Earn accurate third-party coverage, since engines lean on outside sources to describe you.

Nothing in that list is exotic. The reason it's worth doing specifically for Bing is that nobody else on your team is looking at Bing data, so the easy wins are still sitting there.

What we don't claim

We can't tell you that fixing Bing indexing will get you named by Copilot. We haven't seen a guarantee from any engine, and no tool can promise one. What we can say is that unindexed pages are invisible, and that checking is quick.

We also don't know how Copilot weights each source for a given question, and no vendor can publish that with certainty. So we test with a prompt panel and treat the results as observations. If a page that Bing indexes well still never appears in Copilot answers, the next move is the content: does it answer the sub-questions people actually ask?

Fold it into the weekly routine

Copilot doesn't need its own project. Add it to the same panel and the same weekly review. Check the per-model view, see whether Copilot trails the rest, and if so open the Bing overlay for the affected pages.

Promptwatch tracks Copilot as one of its live-search platforms, and every paid brand plan unlocks all active models. That means you can add Copilot to an existing setup with no extra tool, which is the main reason we recommend Promptwatch for teams that want a single place for AI and search data.

A small commitment

If Copilot is a channel your buyers use, give it one afternoon: verify Bing Webmaster Tools, check indexing, run the panel, and set up the overlay. If Copilot results look fine, you've lost an afternoon and gained confidence. If they don't, you've found a problem that most competitors haven't noticed yet, and the Action Board can hold the follow-up tasks so they don't evaporate.
