How B2B buyers research suppliers before making contact

Here is the uncomfortable part of B2B selling: the conversation that decides whether you win often happens without you.

A buyer hears your name from a colleague, sees you in a search result or gets you as one of five options from an AI assistant. They open your website, check who is behind the company, look for work like theirs and compare you with two or three alternatives. By the time an enquiry lands in your inbox, the buyer has usually done most of the thinking. Often they already have a favourite.

That is good news, once you see it. A large part of the sale is decided by things you control: how clearly you explain the business, how easy your proof is to find and how consistent your story is wherever a buyer looks. This guide maps what buyers do in that silent stage, what they check and what to fix first, so your company starts the first conversation ahead.

How much of the B2B buying journey happens before first contact?

More than most sales teams assume. Several large bodies of research point the same way.

• In 6sense's 2025 Buyer Experience Report, based on more than 4,000 buyers across North America, EMEA and APAC, 94% of buying groups had ranked their preferred vendors before first contact. They then bought from that early favourite 77% of the time.
• The same research found that buyers complete roughly 60% of the journey before engaging sellers, down from about 70% a year earlier, as buyers reach out sooner for help making sense of AI features and cost pressure.
• Gartner's research on the B2B buying journey found that buyers spend only 17% of their total buying time meeting potential suppliers, and that time is shared across every supplier they are considering.
• In a Gartner survey of 646 B2B buyers, published in March 2026, 67% said they prefer a buying experience without a sales rep, and 45% had used AI tools during a recent purchase.

One caution before you apply these numbers to your own market. Most large buyer studies lean towards technology purchases and larger companies. An owner sourcing a specialist supplier, or a procurement team running a formal tender, follows a different rhythm. The percentages move from market to market. The pattern holds: buyers arrive later, better informed and with a view already forming.

What do B2B buyers do before they contact a supplier?

The journey is rarely a neat funnel. Buyers loop back, pull in colleagues and change their minds. Still, the work they do before contact falls into six jobs. The table shows what the buyer is really asking at each one, what they check and where capable suppliers quietly drop out.

Notice where most suppliers lose. It is rarely at stage six. It is in stages two to five, long before a salesperson could have helped.

Where do B2B buyers look for suppliers?

Buyers use several sources at once and trust them differently. Each one does a different job.

Search engines. Search is still where many long lists begin, especially for specialist, technical or local suppliers. A buyer types the problem, not your company name, so your pages need to use the words buyers use to describe what they need.

AI assistants. Buyers increasingly ask ChatGPT, Gemini, Copilot or Claude to suggest options or explain a category before they visit a single website. They also check what those tools tell them: in a Gartner survey of 645 B2B buyers, 69% said they prefer to validate AI-generated insights with a sales rep.

Colleagues and peers. Buying is a group activity. Forrester's 2026 research found that a typical buying decision now involves 13 internal stakeholders and nine external influencers, and more for complex purchases. Your name has to travel well between people who have never met you.

Reviews, directories and third-party profiles. These are where buyers look for evidence you did not write yourself. Out-of-date or thin profiles quietly undermine a strong website.

Your website. It is the one source you fully control, and the one every other source points back to. It is also where inconsistency shows. In a Gartner survey of 632 B2B buyers, 69% reported inconsistencies between the information on a supplier's website and what its sellers told them.

How are AI assistants changing supplier research?

An AI assistant does not read your website the way a person does. It assembles an answer from whatever it can find and understand: your pages, directory listings, reviews and articles that mention you. When that information is vague, thin or contradictory, the answer about you will be too. Sometimes you will not appear at all.

Two practical consequences follow.

Specific beats clever. "Precision CNC machining of aluminium and stainless steel parts for medical device and semiconductor equipment makers, from prototype to 5,000 units" can be understood, summarised and matched to a buyer's request. "Engineering excellence, delivered" cannot.

Consistency matters more than it used to. If your website, LinkedIn page and directory listings describe different services or sectors, both people and AI tools have to guess which version is true. Guessing rarely works in your favour.

AI tools help buyers build the list. People still confirm the choice. That is why the evidence has to hold up in both places.

Why do referrals not replace a clear website?

Many established B2B companies grow on referrals and conclude that the website matters less. It is the other way round.

A referral sends a buyer to check you, usually with a colleague's recommendation in their head and a few alternatives in another tab. If what they find is vague, dated or hard to match to their need, the recommendation loses its force. A good referral raises the bar your evidence has to clear. It does not lower it.

The companies that turn referrals into contracts most reliably are the ones whose website confirms, in the first minute, what the colleague said.

The Shortlist Evidence Score: a 10-minute self-check

Open your website in a private browser window and read it as if you had never heard of the company. Score each check 0, 1 or 2.

12 to 14: buyers can shortlist you with confidence. Keep the evidence current.

7 to 11: you are shortlistable, but you make buyers work for it. Fix your two lowest scores first.

0 to 6: capable buyers are probably dropping you before contact. Start with clarity and proof.

The score is a working tool built from the buyer research above. It is a diagnostic for your own company, not an industry benchmark.

Worked example: scoring a specialist manufacturer

This is an illustrative example, not a client. Picture a precision engineering company with 25 years of history, loyal repeat customers and most new work arriving through referrals.

• Clarity: 1. The homepage says "precision engineering solutions". A buyer only learns that the company machines complex parts for medical and semiconductor customers on the third page.
• Fit: 1. Sectors are listed, but so are eleven others the company rarely serves.
• Proof: 0. Two excellent project stories exist, in the sales deck.
• Credentials: 2. The ISO 13485 certificate is listed with its scope.
• People: 0. No names beyond a generic sales inbox.
• Consistency: 1. The LinkedIn page still promotes a service the company stopped offering.
• Next step: 1. A phone number and a form, with no word on what happens after.

Total: 6 out of 14. This is a good company that is hard to shortlist.

The three fixes, in order:

1. Rewrite the first screen of the homepage so it says what the company makes, for whom and at what volumes, in the words a medical or semiconductor buyer would use.
2. Move the two project stories onto the website, each written as the requirement, what made it difficult, the approach and the result.
3. Rebuild the contact page with the name of the person who replies, the information that helps them quote and the usual response time.

None of these needs a new channel or a bigger budget. Each one makes the company easier to choose for every buyer who is already looking. For more on how industrial buyers assess suppliers, read how manufacturing buyers choose suppliers.

What should you fix first?

Prioritise by buyer risk, not by channel fashion. More traffic to an unclear website only spreads the confusion further.

1. Clarity. Make the first screen say what you do, for whom and why it wins. The 30-second positioning test shows you where it breaks.
2. Proof. Put two or three specific examples where buyers can find them. How to ask customers for testimonials gives you the requests and questions to use.
3. Consistency. Give the website, LinkedIn company page, Google Business Profile, directory listings and sales deck the same one-line description, services and sectors.
4. The contact path. Name who replies, what information helps and when the buyer will hear back.
5. Reach. Once buyers who find you can shortlist you, more visibility starts paying for itself.

What does this mean for the first sales conversation?

If the buyer arrives with a favourite already forming, the first call is rarely an introduction. It is a confirmation, or a chance to change their mind.

Three habits help:

• Ask what they have already read and who else they are considering. You learn what the silent stage told them.
• Tell the same story as the website. When the salesperson and the website disagree, buyers notice, and trust drops.
• Help them defend the choice internally. With a dozen or more people involved, your champion needs a clear summary, the proof and a simple reason to say yes. Why B2B buyers choose the safe supplier shows what makes a choice easy to defend.

The advantage is in the silent stage

The companies that win more often are not always the strongest. They are the easiest to understand and verify when nobody from the company is in the room.

Clarity, proof and consistency are within your control, and they compound. Every buyer who researches you quietly meets the same strong case, whether they came from a referral, a search or an AI assistant. Score your company this week, fix the two lowest lines and start the next conversation ahead.
