There's an AI engine that almost all B2B companies ignore in their visibility strategy. Not ChatGPT. Not Perplexity. Not Gemini.

Microsoft Copilot.

Yet Copilot handled more than one billion queries in 2025 — and it's integrated directly into Word, Excel, PowerPoint, Teams and Outlook. When a purchasing director writes an email in Outlook and asks Copilot to "find me a provider in [your field]", the response appears without them leaving their work environment.

This is the most under-optimised B2B acquisition channel of 2026.

What makes Copilot fundamentally different

Copilot isn't ChatGPT with a Microsoft logo. It's a distinct ecosystem, with its own citation logic — and three specificities you won't find on any other AI engine.

1. Copilot works exclusively on the Bing index

Unlike Gemini which relies on Google Search, Copilot uses exclusively the Bing index. If your site isn't indexed on Bing — or poorly positioned — you don't exist for Copilot, regardless of your Google visibility.

This is the mandatory starting point. And it's the one that almost all French and Belgian companies have missed: they optimise for Google, never for Bing.

2. Copilot always cites its sources with clickable links

This is an important difference from ChatGPT, which doesn't systematically cite its sources. Copilot displays citations inline in its response and lists them at the bottom — each citation is a clickable link to your site. This is direct, qualified, traceable traffic.

3. Copilot is integrated into Microsoft 365

This is the most strategic B2B lever. Copilot is available in Word, Excel, PowerPoint, Teams and Outlook for companies subscribed to Microsoft 365. Your prospects and clients use it in their daily work environment — not on a separate interface.

The 10-minute test: check your Copilot visibility

Go to copilot.microsoft.com or open Copilot in the Microsoft Edge sidebar.

Preliminary step — check your Bing indexing

Before any visibility test, check that your site is well indexed on Bing: Type in Bing: site:yourdomain.com

If no results appear, your site isn't indexed on Bing. This is your absolute priority before any Copilot optimisation.

Sector discovery prompts

"What are the best providers in [your field] for a B2B company in [your country]?" "Recommend an expert in [your service] with a [your differentiator] approach. I'm looking for an SME." "Which companies are recognised for [your field] in [Belgium / France]?"

Direct verification prompts

"What is [your company name]?" "What services does [your company name] offer?"

Microsoft-specific prompt

"I'm looking for a [provider / tool / service] for my team that uses Microsoft 365. Any recommendations?"

This prompt is unique to Copilot — it activates the Microsoft ecosystem compatibility signals that Copilot particularly values.

Interpreting the results

You appear with clickable links to your site ✅

This is the best possible result on Copilot — your citations are directly actionable for the prospect. Check that the cited pages are relevant and up to date.

You're mentioned without a link ⚠️

Copilot knows you but doesn't cite your site. This often indicates a Bing indexing problem or a lack of authority signals in the Microsoft ecosystem.

You don't appear ❌

Either your site isn't indexed on Bing, or your content isn't structured for Copilot extraction. The two problems are distinct and have different solutions.

Why Copilot doesn't cite you: the real reasons

1. You're not indexed on Bing

This is the most frequent cause — and the easiest to fix. Most companies focus on Google Search Console and forget Bing Webmaster Tools. If Bing hasn't crawled your site, Copilot can't cite you — regardless of the quality of your content.

2. Your LinkedIn company profile doesn't exist or is inactive

LinkedIn is a Microsoft property. Copilot uses LinkedIn signals to verify the existence and credibility of your entity in the Microsoft ecosystem. A complete and active LinkedIn company profile is a direct trust signal for Copilot — more than for any other AI engine.

3. Your content isn't structured for extraction

Copilot favours content with direct answers and clear structures. Comparison queries typically cite 3 to 5 sources with strong weighting on review platforms. Procedural queries cite a single authoritative source. Your content must match the type of query you're targeting.

4. Your security and trust signals are insufficient

Microsoft places particular importance on security signals in source evaluation: impeccable HTTPS, correct security headers, visible contact information, up-to-date privacy policy. A site with security warnings is penalised in the Microsoft ecosystem.

5. You have no presence in the Microsoft ecosystem

Bing Places, Microsoft Start, Microsoft partnerships — companies present in the Microsoft ecosystem benefit from a structural advantage in Copilot citations.

The 6 Copilot-specific levers

Lever 1 — Register on Bing Webmaster Tools immediately

It's free and it's the absolute prerequisite. Go to bing.com/webmasters, log in with your Microsoft account, and submit your sitemap. Bing has offered since February 2026 an "AI Performance" report showing exactly how many times your content is cited in Copilot — it's the only AI engine to offer this level of transparency on its citations.

Lever 2 — Optimise your LinkedIn company profile

Complete every section of your LinkedIn company page: detailed description with your business keywords, specialities (the "Specialties" field), company size, sector, location. Publish at minimum 2 times per week. Consistency between your site, LinkedIn profile and other online presences strengthens your entity in the Microsoft ecosystem.

Lever 3 — Add Organization Schema with LinkedIn match

In your JSON-LD Organization, explicitly add the link to your LinkedIn profile:

{
  "@type": "Organization",
  "name": "Your Company",
  "url": "https://yoursite.com",
  "sameAs": [
    "https://www.linkedin.com/company/your-company"
  ]
}

This explicit connection between your site and LinkedIn profile is a strong signal for Copilot.

Lever 4 — Write content aimed at Microsoft 365 B2B decision-makers

Your prospects who use Copilot in Teams or Outlook have very specific questions: how to choose a provider, how to evaluate a solution, how to justify an investment internally. Create content that answers exactly these questions — not generic articles about your sector.

Lever 5 — Look after your Microsoft trust signals

Check your HTTPS and security headers with securityheaders.com. Ensure your contact page, T&Cs and privacy policy are easily accessible. These signals matter more on Copilot than on other AI engines.

Lever 6 — Track your citations with Bing AI Performance

This is the unique advantage of Copilot: you can measure your citations. In Bing Webmaster Tools → AI Performance, you see how many times your pages have been cited in Copilot responses, the queries that triggered these citations, and the best-performing pages. Use this data to identify what works and replicate it.

The Bing Webmaster Tools AI Performance dashboard

Launched in February 2026, this report is an industry first — no other AI engine offers this level of transparency on its citations. It gives you access to:

  • Citation count: how many times your pages have been cited in Copilot
  • Grounding queries: the exact questions that triggered your citations
  • Performance by page: which URLs are most cited
  • Time trends: the evolution of your visibility over time

For any B2B company starting to work on its AI visibility, this is the most concrete measurement tool available today.

Copilot in Microsoft 365: the most underestimated B2B use case

Beyond copilot.microsoft.com, Copilot is integrated throughout the Microsoft 365 suite. Concretely, your prospects can find you:

  • In Outlook: by asking Copilot to find a provider while writing a prospecting email
  • In Teams: by searching for resources on a topic during a meeting
  • In Word: by asking for recommendations while writing a specification

These touchpoints occur in your prospects' workflow — without explicit search intent. This is a level of integration no other AI engine achieves today.
