How Surveys Turn B2B Marketing from Guesswork into Certainty

A survey in B2B marketing is a systematic way of finding out what troubles your customers, how they choose suppliers and why they buy elsewhere. It replaces assumptions with facts: it shows what to write about, which arguments to use and which customers are at risk of leaving. In 2026 this matters more than ever. According to a report by Edelman and LinkedIn, 85% of decision makers list among the main criteria for their final choice whether the supplier demonstrated that it understands their specific problems. The fastest way to understand them is to ask.

At a glance

1. A survey is the cheapest insurance against poorly targeted campaigns. Ask before you spend the budget.
2. Buyers now choose suppliers on their own and earlier. Whoever understands their problems makes the shortlist.
3. Start with three surveys: satisfaction of existing customers, reasons for lost deals and an industry benchmark.
4. Keep the questionnaire short. Two to three questions get more than double the response rate of seven or more.
5. Turn the results into content. Competitors cannot copy your own data, and AI search engines like to cite it.
6. Follow every answer with an action: a tag, an email, a call from a salesperson. A survey with no response is more likely to annoy customers.

In short: what a survey brings, where to start, how long the questionnaire should be and what is at risk

• What it brings: facts instead of assumptions about what troubles customers, how they choose suppliers and why they leave. According to Edelman and LinkedIn, for 85% of decision makers it matters whether the supplier understands their problems.
• Where to start: with three surveys, satisfaction of existing customers with an NPS question, a questionnaire after a lost deal and an industry benchmark.
• How long the questionnaire should be: as short as possible. Two to three questions have a median response rate of 16% according to Survicate, seven or more questions 6.9%.
• What is at risk: a survey with no reaction to the answers is more likely to annoy customers. Every answer should be followed by a tag, an email or a call from a salesperson.

Why every B2B marketer should talk to their customers before launching a campaign

Companies that invest in advertising without a real understanding of their customers' needs are often shooting in the dark. Market surveys and customer data can reveal what actually troubles B2B clients, which decisions they make and why. Marketing then rests on facts instead of assumptions, which lowers the risk of poorly targeted campaigns and wasted budgets.

A typical situation: marketing prepares a campaign about saving time, because it believes that is what bothers customers most. Ten phone calls with customers would have shown that few of them care about time, but they are afraid that switching to a new system will bring operations to a halt. The campaign answers a question nobody asked, and the argument that would have worked is missing.

In B2B the cost of such a mistake is higher than in B2C. The target group is smaller, every contact is worth more and a purchase takes months. A message that misses the mark does not just mean a lower click rate. It means losing a place on a shortlist you will not get back onto in this buying cycle.

What changed in 2025 and 2026

Buyers now make up their minds earlier, on their own and with the help of artificial intelligence. They come to the first conversation with a salesperson with their opinion already formed. That makes it all the more important to know what troubles them before they ever contact you.

This means three things for surveys. First, according to Edelman and LinkedIn, the winning supplier is the one that shows it understands the customer's problems. You will not get there with generic phrases, only with knowledge you gain by asking. Second, according to 6sense, 85% of buyers have previous experience with the winning supplier. Your existing customers are therefore the most valuable group to listen to, because they are the ones deciding on the next purchase. Third, visits from search are declining and AI provides the answers. If you publish your own survey data, there is a chance AI will cite it.

A note on the numbers: Most of these studies come from large markets and from technology purchasing. The Survicate figures refer to questionnaires shown on a website or in an app, not questionnaires sent by email. For a smaller company with a few dozen customers the numbers will be different. The principle is the same, though: the better you know your customer, the easier it is to make the shortlist.

Uncovering customers' real pain points

Short questionnaires, phone interviews or online polls let you gather direct feedback from the decision makers in companies. Unlike the B2C segment, a B2B purchasing process usually involves more participants and a longer cycle, so it is essential to know what each role in that process is actually dealing with. A survey often uncovers pain points the team had no idea about, because it had been relying on its own assumptions.

Ask several roles, not just your contact person. Your contact at the company is usually the user of the service. But the CFO, the head of operations or the purchasing manager also have a say in the purchase. Edelman and LinkedIn call them hidden decision makers, and according to their report more than 40% of deals stall because of disagreement within the buying group. When you know what each role is dealing with, you can prepare the argument each of them needs.

Combine numbers and words. Closed questions with a scale show how big a problem is and whether it is getting better. The open question “What should we improve first?” shows why. Write down the most valuable sentences from open answers word for word. They often become campaign headlines, because they are written in the customer's own language.

Add interviews to the questionnaire. A questionnaire answers what you ask. An interview reveals what you would not have thought to ask. A proven order: first eight to twelve short interviews that bring out the topics, and only then a questionnaire that measures how widespread each topic is.

Which surveys pay off in B2B

Each survey has a different goal and a different target group. The table shows the ones that bring the most value in B2B for the least effort.

Satisfaction with an NPS question. The question “How likely are you to recommend us to a colleague?” on a scale of 0 to 10 splits customers into promoters (9 and 10), passives (7 and 8) and detractors (0 to 6). The NPS figure itself matters less than what you do with each group. In Quanda, NPS is a separate question type and the result is calculated automatically.

Lost deals. The most valuable and least used survey in B2B. A company that did not choose you knows exactly where the competitor was better. Three questions are enough: what made the decision, where we fell short and what we would have to change for you to consider us next time. They answer more often than you would expect, as long as the email is personal and you promise nobody will try to talk them round.

12 practical examples of B2B surveys

Everyone knows the general advice. Here are specific ideas for different industries that you can adapt for your own company.

1. NPS after a completed job. An installation company sends a two-question questionnaire a week after handing over the work: NPS and “What should we do differently next time?”. Promoters receive a thank you with a request for a reference, detractors get a call from the project manager. After a year the company knows which project phases annoy customers the most.

2. Three questions after a lost deal. A supplier of industrial compressors sends a questionnaire to companies that did not accept its offer. Within six months it finds out that the deciding factor is not price, as sales believed, but delivery time for spare parts. It adjusts its service offer and starts highlighting it in every presentation.

3. An industry benchmark as a lead magnet. A recruitment agency asks 200 manufacturing companies how long it takes them to fill a technician position and how much it costs. It publishes the summary freely on its website and puts the full report with a regional comparison behind a form. How to turn a survey into a lead magnet is covered in the article Lead magnets in B2B marketing.

4. Surveying the whole buying group. At its larger customers, an enterprise software supplier sends a short questionnaire not only to the main contact, but also to the CFO and department heads. It turns out that users are happy, but management does not see the benefit in numbers. The company prepares a quarterly savings overview for management.

5. Onboarding questionnaire for a new customer. A marketing agency sends five questions after the contract is signed: the main goal, who approves the outputs, the preferred way of communicating, what went wrong with the previous agency and what success looks like in a year. The answers get tags, and the first month of the partnership is guided by them.

6. Testing topics before creating content. Before an accounting firm writes an e-book, it sends its database one question: “Which of these five topics worries you most this year?”. Each answer assigns a tag. The e-book is written on the winning topic, and the people who chose it are the first to get an invitation.

7. Rating after a webinar or event. A packaging machine manufacturer sends webinar attendees three questions: how useful the content was, which topic they want next time and whether they are interested in a tour of the production line. Anyone who ticks the tour is contacted by a salesperson within two days. The others receive the recording and an invitation to the next webinar. Before the event it pays to ask about the date, venue and programme, the ready-made template is in the library as the Company event planning survey.

8. Lead qualification. A supplier of solar power plants for businesses asks prospects from its website to fill in a short questionnaire: electricity consumption, roof type, time horizon. The salesperson calls first those who want the installation within six months. The ready-made template with a suggested scoring is in the library as the Lead qualification survey.

9. Retention survey. An office supplies distributor notices that a customer has been ordering less over the past three months. Instead of offering a discount, it sends a questionnaire asking what has changed. Often it is something small, such as a missing item in the range or a change of buyer on the customer's side. The ready-made template is in the library as the Customer retention survey.

10. Upsell survey. An IT company that manages its customers' computers asks which other services they handle elsewhere: backup, telephony, printers. Every ticked service is a lead for the salesperson and also a signal of what to send content about. The ready-made template is in the library as the Upsell survey for existing customers.

11. Customer service rating. A service organisation for medical equipment sends one scale question and a comment field after every closed request. The head of service goes through the critical answers every week and within a month sees which types of intervention annoy customers most often. A fuller template is in the library as the Customer service satisfaction survey.

12. Testing pricing and packages. Before changing its pricing, a software company asks existing customers which features they use, which they would pay extra for and which they do not need. It then builds the new packages around actual usage, not the product team's estimates.

Practical tip: Do not start with a blank page. The questionnaire library has ready-made templates, such as the Customer satisfaction survey, Project delivery satisfaction survey, Website evaluation survey or Upsell survey. Just adjust them and send them out.

How to prepare a questionnaire people will answer

A decision maker at a company receives dozens of emails a day. A questionnaire that takes a quarter of an hour gets closed. Whether they answer depends mainly on six things.

One goal, one decision. Before you write the first question, write down what decision you will make based on the results. Every question that does not contribute to that decision goes.

A short questionnaire. According to the Survicate benchmark, questionnaires with two to three questions have a median response rate of 16%, those with seven or more questions 6.9%. Keep ongoing ratings to one to three questions. Split a longer annual survey into pages and state in the introduction how many minutes it will take.

A familiar sender. According to SurveyMonkey, email surveys that B2B companies send to their own customers have an average response rate of 49%. The relationship makes the difference. An invitation from an account manager the customer knows works better than an email from “the marketing team”. In Quanda, automatic sender selection takes care of this: each contact receives the invitation from their own contact owner, even within a single campaign.

Clear questions. One question, one thing. Instead of “How satisfied are you with the speed and quality of deliveries?”, ask two questions. Avoid leading wording such as “How much do you appreciate our fast support?”. Put one open question at the end. How to put the questions together is described in the article 6 steps how to create a survey.

Logic instead of unnecessary questions. Someone who answers that they do not use a service does not need to rate it. In Quanda you set up skipping or ending the questionnaire based on an answer in the Logic tab.

Results back to respondents. Send customers a short summary: what you found out and what you will change as a result. Next time they will be happier to answer, because they can see their opinion counted for something.

How many answers are enough

In B2B you often ask dozens of customers, not thousands. That is not a problem as long as you know what you expect from the results.

• You are looking for topics and problems: eight to twelve interviews or open answers are enough. After that they start to repeat and new ones come in slowly.
• You want figures for internal decisions: try to get answers from at least half of the customers the decision affects.
• You want to publish the figures: plan on at least a hundred answers. With a hundred answers the result can differ from reality by roughly ten percentage points, with four hundred by five.

Who answered matters more than how many. If only your happiest customers answered, the result will look nice and be misleading. In analysis of answers you can filter results by contact or company data, such as industry and size, and see whether an important group is missing.

Data as the basis for content and arguments

Survey results can be turned into case studies, white papers or statistics that strengthen the credibility of your brand. When a company can back up its claims with specific figures from its own research, it gains a stronger position than competitors who work only with generic phrases. The same data also serves the sales team in negotiations with clients.

A single survey gives you content for several months:

• A summary article on your website, freely available. It is read by people and by AI search engines, which cite specific figures with their source.
• A full downloadable report behind a form. A lead magnet your competitors cannot copy.
• An email series with one finding in each message. Your database gets a reason to open your emails.
• A webinar with an analysis of the results and a discussion. Attendees ask questions and you get more topics.
• Sales materials: three figures a salesperson can use in a meeting. “Two thirds of companies in your industry face the same issue” is a stronger argument than “our solution is the best”.

According to Pew Research Center, only 8% of people click through to a website when Google shows an AI summary, compared with 15% without one. If you want to be mentioned in AI answers, you need something on your website that cannot be found elsewhere. Your own survey data is exactly that kind of content. Always state figures with the number of respondents, the collection period and a description of who you asked. Credibility is worth more than a catchy headline.

In Quanda you prepare a report with charts and comments in the final report and download it as a PDF. You can export the answers, including respondent data, from completed surveys to CSV.

From answer to action

A survey nobody responds to is worse than no survey at all. The customer gave you their time and expects something to happen. It works best when the response is set up in advance. An example for a satisfaction survey with NPS:

In Quanda this is handled by automation in a survey: once the questionnaire is completed, the contact gets a tag, receives a thank you and you get a notification. For multiple choice questions you assign a tag based on a specific answer, provided you send the questionnaire by email from Quanda. You then build further campaigns on the tags, and salespeople can filter who to call. Contact scoring shows who keeps opening your other emails after the questionnaire.

Continuous measurement instead of a one-off exercise

The best results come from surveys repeated at regular intervals, not from a single round of data collection. Tracking changes over time shows whether the marketing strategy is really working and whether customer needs are changing faster than the company can respond. A regular survey thus becomes part of a company culture built on data.

Same questions, same time of year. Keep the key questions, such as NPS and satisfaction with the main parts of your service, the same every year. That is the only way to see whether things are improving. Add new questions alongside them, not in their place.

Ongoing ratings run on their own. Set up a short questionnaire after a completed job or resolved request once and let it go out automatically. You do not have to think about it, and data comes in every week.

Watch out for survey fatigue. Send each contact no more than one questionnaire per quarter. If you contact them for the third time in a month, they will stop opening your other emails too.

Results have an owner. Decide who goes through the results of each survey, who decides on changes and when you will tell customers about them. Without an owner, even the best survey ends up in a spreadsheet nobody opens.

The most common mistakes

• A questionnaire without a goal. Nobody finishes thirty questions asked “so we know everything”, and the answers lead nowhere.
• Asking only happy customers. A survey among loyal customers confirms what you want to hear. Also ask those who left or bought elsewhere.
• Leading questions. “How satisfied are you with our excellent support?” measures nothing except your self-confidence.
• A survey as an excuse to sell. If a salesperson calls with an offer right after the questionnaire is filled in, the customer will not answer next time. Sales follow-up belongs only where the respondent has shown interest themselves.
• Silence after the survey. Customers gave you their time. If nothing changes and they never even hear the results, they will not answer a second time.
• Figures without context. “87% of customers are satisfied” without the number of respondents and the date convinces nobody.

Tip: You can learn how to create, send and evaluate a questionnaire in the online course Working with Questionnaires and Collecting Feedback. How to turn feedback into a business tool is shown in the course Feedback as a Business Tool. The courses are free.

Where to start: five steps for one week

• Write down one decision you want to make based on data, for example what your next campaign will be about or why you are losing deals.
• Call five to eight customers and ask what troubles them most in their work right now and how they would choose a supplier.
• Build a questionnaire from the answers with no more than five questions, including one open question. You can also use a template from the questionnaire library.
• Send it by email from Quanda in the name of someone your customers know, and set up tags and thank you messages based on the answers.
• Evaluate the results within two weeks, send respondents a summary and use one finding in your next campaign.

Conclusion

Surveys in B2B are neither an academic discipline nor an expensive agency project. They are the fastest way to stop guessing what troubles your customers. In 2026 there is one more reason: buyers choose suppliers earlier and on their own, and the one that makes the shortlist is the one that shows it understands their problems. A company that asks regularly, responds to the answers and uses the results in its content and sales has a lead over the competition that cannot be copied.
