Microsoft Copilot Is Changing How Companies Choose Vendors
Introduction
There's an AI recommendation channel that almost nobody in the B2B world is talking about, and it's already embedded in the daily workflow of millions of office workers.
Microsoft Copilot, integrated into the Microsoft 365 suite (Word, Excel, PowerPoint, Outlook, Teams), is now a standard feature for enterprise and business Microsoft 365 subscribers. That means employees at millions of companies can ask Copilot questions and receive AI-generated answers without leaving their work environment.
And they're using it to research vendors.
When a marketing manager needs to recommend an email platform to their VP, they might ask Copilot inside a Teams chat: "What are the best email marketing tools for mid-size companies?" When a facilities manager needs to find a commercial cleaning service, they might ask Copilot in Word while drafting an RFP: "What commercial cleaning companies operate in the Phoenix area?"
These are vendor selection queries happening inside the enterprise, in a closed environment, and they're being answered by an AI that draws from Bing's search index. If your business isn't visible to Bing, you're invisible to Copilot. And if you're invisible to Copilot, you're missing a growing B2B discovery channel that operates inside your prospective clients' own productivity tools.
AI search optimization for B2B companies needs to include Copilot. Here's why and how.
How copilot makes vendor recommendations
Copilot's recommendation process is distinct from ChatGPT or Perplexity, and understanding its mechanics is important for optimization.
Copilot uses Bing as its primary web data source.
When Copilot generates a response that requires web information (anything beyond the user's own documents and organizational data), it queries Bing's search index. This means your Bing visibility directly determines your Copilot visibility.
Most B2B companies optimize exclusively for Google and ignore Bing. This has been a defensible choice for traditional SEO (Google has 90%+ of search market share). But for Copilot visibility, Bing is the only index that matters.
Copilot can access organizational data + web data.
Copilot has a unique capability: it can combine information from the organization's internal documents (SharePoint, Outlook, Teams conversations) with web-sourced information. This means a Copilot response might say: "Based on our team's previous conversations about email platforms and current market options, here are some recommendations..."
This dual-source capability means Copilot responses can be influenced by both your web presence and by any internal mentions of your company within the prospect's organization. If a colleague previously emailed about your company, mentioned it in a Teams chat, or saved a document about you in SharePoint, Copilot can surface that alongside web results.
Copilot's context window includes the user's current task.
If someone is writing an RFP in Word and asks Copilot for vendor suggestions, Copilot considers the context of the document. If the RFP specifies "must serve the Phoenix metro area" or "budget under $5,000/month," Copilot incorporates those constraints into its recommendation. This makes Copilot's vendor suggestions more contextually relevant than generic ChatGPT queries.
Why this matters for B2B companies
Copilot-influenced vendor decisions are different from ChatGPT-influenced consumer decisions in three important ways.
Higher transaction values. B2B purchase decisions often involve five, six, or seven-figure contracts. A Copilot recommendation that shapes a vendor shortlist for a $50,000 software purchase or a $200,000 consulting engagement has dramatically higher per-recommendation value than a consumer ChatGPT recommendation for a $200 dental visit.
Committee-based decisions. B2B purchases typically involve multiple stakeholders. When one stakeholder asks Copilot for vendor suggestions and shares the response with the team (which is easy to do within Microsoft 365's collaborative environment), the AI recommendation reaches the entire buying committee, not just one individual.
Embedded in workflow. Copilot doesn't require the user to leave their work environment. They don't open a separate browser tab for ChatGPT. They ask Copilot inside the tool they're already using. This reduces the friction of AI-powered research to near zero, which means it happens more frequently than deliberate ChatGPT sessions.
The bing factor: why most B2B companies have a blind spot
Here's the uncomfortable reality: most B2B companies have put near-zero effort into Bing visibility. Their SEO is 100% Google-focused. Their local listings are Google-centered. Their analytics track Google traffic. Bing is an afterthought.
For traditional search, this made sense. Bing handles roughly 3 to 8% of web search volume. The ROI of Bing-specific optimization was marginal.
For Copilot visibility, this creates a massive blind spot. Copilot reaches hundreds of millions of Microsoft 365 users who are asking vendor-related questions inside their daily work tools. And every one of those queries runs through Bing, not Google.
The businesses that have strong Bing presence (either intentionally or because their broad web presence is indexed by Bing automatically) appear in Copilot recommendations. The businesses with Google-only visibility do not.
Bing optimization for Copilot is the single highest-impact, lowest-effort B2B AI opportunity available right now. Most competitors haven't done it, because most people still think of Bing as a minor search engine rather than the data backbone of Microsoft's entire AI ecosystem.
How to optimize for microsoft copilot
Step 1: Ensure your website is fully indexed on Bing.
Submit your site to Bing Webmaster Tools (bing.com/webmasters). Verify ownership. Submit your sitemap. Check that your key pages (homepage, service pages, about page, blog content) are indexed. Many businesses discover that Bing has only indexed a fraction of their site, while Google has indexed everything.
Step 2: Claim and optimize your Bing Places listing.
Bing Places is Bing's equivalent of Google Business Profile. For local and regional businesses, an accurate, complete Bing Places listing directly influences Copilot's local business recommendations. Ensure your business name, address, phone, services, and description match your Google Business Profile and all other directory listings.
Step 3: Build citations on Bing-indexed sources.
Not all web sources are equally indexed by Bing. Major directories, established industry publications, BBB, LinkedIn, Facebook, and other high-authority platforms tend to be well-indexed on Bing. Prioritize citations on these sources, particularly LinkedIn (a Microsoft property that Bing indexes deeply).
Step 4: Optimize LinkedIn aggressively.
LinkedIn is a Microsoft property. Bing has deep integration with LinkedIn data. Your LinkedIn company page and personal profiles are likely among the most Bing-visible assets you own. Ensure your LinkedIn company page has a complete description, accurate service listings, published articles, and employee profiles that reinforce your company's entity data.
For B2B companies, LinkedIn optimization is arguably the single most important Copilot-specific action you can take.
Step 5: Publish content that answers B2B vendor selection queries.
Think about the queries a procurement manager or department head would ask Copilot: "What are the best [your product category] for [industry/size/need]?" Publish content on your website and LinkedIn that directly answers these queries with specific, authoritative information.
Step 6: Build review presence on platforms Bing indexes.
For B2B companies, this means G2, Capterra, TrustRadius, and Clutch. These platforms are well-indexed by Bing and frequently appear in Copilot's vendor research responses. Even a small number of reviews (10 to 15) on these platforms can significantly influence Copilot's recommendations for your product category.

The enterprise AI recommendation you're not tracking
Here's what makes Copilot particularly difficult to monitor: the recommendations happen inside enterprise environments you can't see. When a procurement manager at a Fortune 500 company asks Copilot for vendor suggestions inside a Teams chat, you have no visibility into that interaction. There's no referral source you can track. There's no Copilot analytics dashboard you can access.
The only way to influence Copilot recommendations is to build the signals before the query happens. Bing visibility, LinkedIn presence, B2B review platform profiles, and authoritative web content are the inputs. The recommendation happens behind closed enterprise doors, and the only evidence you'll see is either a new lead that mentions "we found you through research" or silence.
This is why proactive Copilot optimization is essential for B2B companies. You can't react to what you can't see. You can only build the presence that puts you in the answer before the question is asked.

Frequently asked questions
The AI channel nobody is watching is the one inside the office
ChatGPT gets the headlines. Perplexity gets the tech press coverage. Google AI Overviews get the SEO industry's attention. But the AI channel that's quietly reshaping B2B vendor selection is the one embedded inside the tools that 400+ million Microsoft 365 users open every morning.
Copilot doesn't announce itself. It doesn't have a consumer brand campaign. It just sits inside Word, Excel, Teams, and Outlook, waiting for someone to ask it a question. And when that question is "Who should we hire for this?" or "What's the best platform for this?", the answer comes from Bing, not Google.
Your B2B competitors probably haven't figured this out yet. That's your window.
Run your free AI visibility audit at yazeo.com and see your Bing-powered AI presence alongside your ChatGPT, Gemini, and Perplexity visibility.
