How AI Search Finds Suppliers: A B2B Buyer's Path
A procurement manager types a question into an AI assistant and gets back a shortlist of suppliers. Between the question and the shortlist, the assistant goes through a series of steps, and a supplier can drop out at each one. This guide follows that path, with an example buyer, and shows what your website needs at every step.
The example
Maria buys equipment for a metal fabrication company. She needs a new hydraulic press and asks an AI assistant:
Which manufacturers make 200-ton hydraulic presses suitable for export to the EU?
The example is illustrative, but the steps below describe how AI search assistants generally work.
Step 1: the assistant decides it needs to search
For a question about current suppliers, an AI assistant with search will usually look things up rather than rely only on what its model learned in training. It turns Maria's question into one or more searches.
What this means for you: the words buyers use matter. "200-ton", "hydraulic press" and "EU" or "CE" are the terms that need to appear on your pages.
Step 2: it looks for relevant pages
The assistant searches its own index or a search partner's index for pages that match. Those indexes are built by crawlers such as OAI-SearchBot, Claude-SearchBot and PerplexityBot, plus traditional search engines.
Where suppliers drop out: if your robots.txt blocks those crawlers, or your firewall refuses them, your pages may not be in the index at all. See Is Your Firewall Blocking AI Search?
Step 3: it reads the pages
The assistant then reads the most promising pages. Sometimes it fetches them live, which is what ChatGPT-User and Claude-User visits in your server logs represent. A ChatGPT-User request for your product page is a strong sign someone's question led there.
Where suppliers drop out: pages that load their content with JavaScript, hide specifications in images, or return errors give the assistant little or nothing to read.
Step 4: it extracts facts
From each page, the assistant pulls out facts that answer the question: company name, product range, capacity, certifications, export markets.
Where suppliers drop out: vague copy. "We provide high-quality pressing solutions" can't answer Maria's question. "200-ton four-column hydraulic press, CE marked, exported to 40 countries" can.
Step 5: it compares sources and builds the answer
The assistant combines what it found, often across several websites: your site, industry directories, trade platforms, articles. It names a few suppliers and may cite the pages it used.
Where suppliers drop out: inconsistency. If your website, your directory listings and your trade platform profiles describe you differently, the assistant has less confidence in any of them.
Step 6: the buyer clicks, or doesn't
Maria reads the shortlist. She may click a cited link, search a supplier by name, or ask a follow-up question such as "Which of these offers on-site installation in Poland?"
What this means for you: being named is the start. Your site still has to convince her once she arrives, and follow-up questions need answers too, such as service, lead times and support.
The supplier's checklist
| Step | What your website needs |
|---|---|
| 1. Search | The terms buyers use, in plain text |
| 2. Index | AI search crawlers allowed in robots.txt and through your firewall |
| 3. Read | Content in the HTML, not only in JavaScript, images or PDFs |
| 4. Extract | Specific facts: models, capacities, standards, markets |
| 5. Compare | Consistent facts across your site and third-party listings |
| 6. Click | Clear next steps: contact details, quote request, support info |
How to check where you drop out
Steps 2 and 3 are visible in your server logs: which AI crawlers visit, which pages they read, and which requests fail. How to Check Which AI Crawlers Visit Your Website explains how.
Steps 4 to 6 are visible in the answers themselves. Ask the questions your buyers ask, in the AI assistants they use, and record who gets named. Do it again each month.
FAQ
Do AI assistants always search the web before answering?
No. Whether an assistant searches depends on the product, the settings and the question. Questions about current suppliers and prices are more likely to trigger a search.
Does the AI only use my website?
No. Assistants combine many sources, including directories, trade platforms, reviews and articles. Your own website is the source you control most directly.
Why does the same question give different answers?
AI answers vary with wording, user context, location and time. That's why testing several related questions, more than once, gives a more reliable picture than one test.
What is the single most important fix for most suppliers?
Make sure AI search crawlers can actually reach your key product pages. Many B2B sites are blocked by robots.txt or firewall rules without knowing it.
