Explori holds the largest database of post-event performance data in the exhibition industry, drawn from more than 4,000 events. Its benchmarks never average an event into one score. Visitor surveys, exhibitor surveys and non-attendee surveys are benchmarked separately, and trade shows, conferences, consumer shows and virtual events are held apart from each other again, because the answers are not comparable across those groups. Now look at the pages that currently rank for “post-event survey questions”. Almost every one of them hands you a single list for everybody.
That gap has a price, and it lands on one desk. Someone at your organisation has to sell next year’s floor space, usually starting a fortnight after the doors close. They will open your post-show report looking for one thing: evidence that exhibitors got something out of the meetings. A satisfaction average built from visitors, exhibitors and speakers in one questionnaire cannot give them that. It gives them a number that no exhibitor recognises as their own experience.
So the question is not which forty questions you could ask. It is which three surveys you run, when each one goes out, and which four numbers you can defend afterwards. A survey that asks every audience the same questions measures how the event felt and averages away the number that decides rebooking: whether the meetings were worth the trip.
Why one survey for everyone produces the wrong number
Start with what the benchmark structure is telling you. Explori benchmarks four core questions for every survey category: Net Promoter Score (NPS, the zero to ten recommendation question), overall satisfaction, likelihood of return, and a fourth that changes with the format. For trade shows and conferences that fourth question is importance of the event. For virtual events it is value for time. For consumer shows it is value for money.
Read that carefully, because it contains the whole argument. Even the professionals who benchmark thousands of events for a living do not believe that one question set travels across formats and roles. A single questionnaire for your entire audience is therefore wrong twice over: wrong about roles, and wrong about what the fourth question should even be.
The reason is not methodological fussiness. Your visitor and your exhibitor are not two samples of the same population. They are two customers with opposite jobs. The visitor spends time and wants relevance. The exhibitor spends money and wants pipeline. Ask both of them how satisfied they were with the catering and you have collected an opinion. Ask the exhibitor how many of their scheduled meetings actually took place and you have collected a reason to rebook.
Averaging those two into one score does something specific and damaging. If your visitors are delighted and your exhibitors are lukewarm, a blended figure looks respectable, and the one signal that predicts next year’s revenue disappears into it. You will find out anyway, about eleven months later, when the renewal calls go badly.
One questionnaire, two customers, one useless average.
Survey one: what to ask visitors
Once the audiences are split, the visitor survey gets shorter rather than longer, because it no longer has to carry questions that were never meant for this group. Keep it to ten questions or fewer, which is also SurveyMonkey’s own recommendation in the most-cited guide on the topic.
The first block is standard and you should not skip it. The second block is where B2B events differ from every generic template, and it is the block that no survey tool ships with.
| Question | Scale | What it tells you |
|---|---|---|
| How likely are you to recommend this event to a colleague? | 0 to 10 | NPS, comparable against benchmarks |
| Overall, how satisfied were you with the event? | 1 to 5 | Satisfaction, comparable year on year |
| How important is this event to your work? | 1 to 5 | Importance, the trade show benchmark question |
| How many of your scheduled 1:1 meetings actually took place? | Number | Your real meeting completion rate |
| How relevant were the companies suggested to you? | 1 to 5 | Quality of the matching, not the quantity |
| How many of those meetings will you follow up on? | Number | The only leading indicator of business value |
| Was the meeting schedule realistically spaced? | 1 to 5 | Whether you overbooked your own attendees |
| What is the one thing we should change next year? | Open text | The block most organisers under-use |
The middle four questions are the ones worth defending internally when somebody asks to cut the survey down. A recommendation score tells you how the event felt. A meeting completion rate tells you whether the event worked. Those are different facts, and only the second one survives contact with a finance director.
Two of them also connect to a number you should already be tracking. If scheduled meetings and completed meetings diverge, you are looking at your no-show rate, and that figure moves far more with your definition than with attendee behaviour, as we set out in our guide on what a meeting no-show actually is. Ask the question in the survey and you get the participant’s side of a number your scheduler already half knows.
Survey two: what to ask exhibitors
The exhibitor survey is the one that pays for the next edition, so give it its own questions rather than a rebadged visitor form. It is allowed to be slightly longer, because the people answering it have a commercial reason to.
| Question | Scale | What it tells you |
|---|---|---|
| How likely are you to exhibit again next year? | 0 to 10 | Likelihood of return, your rebooking leading indicator |
| How many of your scheduled meetings took place? | Number | Meeting completion from the seller’s side |
| How many of those were with genuine decision-makers? | Number | Whether your qualification held up |
| How would you rate the relevance of the buyers matched to you? | 1 to 5 | Matching quality, separate from volume |
| What proportion of meetings will enter your pipeline? | Percentage band | The closest thing to attributed value you can get on site |
| How did this event compare with others you exhibited at this year? | Better, same, worse | Competitive position, rarely asked and always revealing |
| Was your stand location fair for the package you bought? | 1 to 5 | The complaint that surfaces in renewal calls anyway |
| What would make you increase your spend with us? | Open text | Your product roadmap, written by your customers |
Notice the sixth question. Cross-event comparison is the question most measurement frameworks leave out, and it is the one that tells you whether you are losing budget to a competing show before the loss appears in your rebooking figures. Nicola Kastner, who runs the invite-only ELX community, names it as one of her core metrics for exactly that reason.
Solution: Half of these questions only produce usable answers if the meetings sit in a system that already knows what was scheduled, what was accepted and what was cancelled. Converve’s meeting matrix records that during the event, so the exhibitor survey confirms and enriches your own data rather than asking people to reconstruct their week from memory. The full logic of tying those numbers together is in our KPI framework for B2B event matchmaking.
One more caution on volume. More meetings is not automatically a better result, and exhibitors who were scheduled into an unbroken run of appointments tend to rate relevance lower, not higher, which is the tension we work through in how many meetings a hosted buyer should actually have.
Survey three: what to ask speakers and session chairs
Speakers get the shortest survey of the three, and it should feel like a courtesy rather than an audit. Three questions are enough: whether the audience matched what they were promised, whether the technical and logistical support worked, and whether they would speak again. That third answer is your programme pipeline for next year, and it costs you one question.
Resist the temptation to ask speakers about the catering or the app. They were backstage.
When to send each survey
The three surveys do not share a send time, which is the second thing generic templates get wrong. The evidence on timing is unusually consistent: SurveyMonkey recommends going out within one business day and sending no more than two reminders across two weeks. MPI puts the window at 24 to 48 hours. Explori advises sending within a week of the event closing, again with two reminders.
Exhibitors are the exception, and it is a practical one. On the final afternoon they are dismantling a stand and chasing a courier. A survey that lands then gets deleted, or worse, answered angrily. Give them until the second or third working day.
Send schedule
One survey, four moments
- Day one of the event Announce the survey Tell the room from the stage that you measure the event and that last year’s feedback changed something specific. This is what makes the response rate later.
- As doors close Visitor and speaker surveys Deploy while attendees are leaving, so the invitation is already waiting when they check their phone on the journey home.
- Working day two or three Exhibitor survey Late enough that the stand is packed down, early enough that the meetings are still fresh.
- Day seven and day fourteen Two reminders, then stop Use individual survey links so you chase only the people who have not answered.
- Day thirty Follow-up check with exhibitors One question: how many of the meetings turned into a real conversation? This is where event value stops being a feeling.
What response rate to expect, and what is actually possible
Having a schedule raises the obvious next question, and it is the one every published guide dodges. SurveyMonkey states plainly that “response rates vary by audience and event type” and declines to name a figure. That is honest, and unhelpful when your board wants to know whether 14 per cent is good.
Explori’s research team does give numbers. For conferences and corporate events, a good response rate sits between 10 and 20 per cent depending on event size. For live trade shows, around 12 to 15 per cent. Virtual events run lower, and the advice there is to measure against your engaged audience rather than everyone who registered.
Those are the benchmarks. They are not the ceiling.
Response rates
What is normal, and what is achievable
Nicola Kastner runs post-event surveys for an invite-only community of heads of events at large corporations. Her response rates sit consistently in the eighties and nineties. Her definition of a bad result is anything below 75 per cent, which has happened to her once. She uses no vouchers, no prize draws and no charitable donations.
What she does instead is a four-part mechanism, and none of it is technology. She opens every event with a single slide reading “value for time” and tells the room that this is the metric she manages the event by. Throughout the event, she and her host attribute changes out loud to what people said last year. The survey deploys as attendees are leaving. Afterwards she uses individual survey links, so she can chase named non-responders and join the answers to registration data for segmentation.
Read those four steps again and notice what they have in common. Not one of them happens after the event. A declining response rate is rarely a survey problem. It is usually the visible end of a feedback loop that was never closed, and attendees stop answering when they suspect nothing happens with the answer.
Ask, then act, then say what you changed.
The four numbers to put in front of your board
Three surveys produce more data than a board meeting can absorb, so decide in advance which four numbers travel upwards. A defensible set for a B2B event with a matchmaking programme: exhibitor likelihood of return, meeting completion rate, buyer relevance rating, and NPS reported separately for visitors and exhibitors rather than blended.
Segment before you present. Split exhibitors by stand size, first-time against returning participants, and by number of meetings held. A first-time exhibitor with three meetings and a returning exhibitor with fourteen are having different events, and the average of the two describes neither. If you compare across editions, hold your question wording constant, because a rephrased question resets your own trend line.
One constraint applies before any of that reaches a slide. If a segment contains only a handful of exhibitors, individual answers become identifiable, and an anonymity promise you made in the survey invitation quietly breaks. Set a minimum segment size, five is a workable floor, and report anything smaller only in aggregate. The wider data-protection obligations that sit around participant feedback are covered in our checklist for GDPR-compliant event software, and the anonymity threshold belongs in the same conversation.
The other habit worth building is comparison against yourself. Explori’s default view is a 36-month rolling benchmark rather than an all-time average, precisely because an event three years ago was a different product. Your own trend deserves the same treatment.
Frequently Asked Questions
What are the best post-event survey questions for a B2B event?
The best questions differ by audience. Visitors are asked about relevance and meetings, exhibitors about lead quality and their likelihood of returning, speakers about the session set-up and the audience they got. One questionnaire for all three produces an average that describes none of them.
When should you send a post-event survey?
Visitor and speaker surveys go out as the doors close, so the invitation is waiting on the journey home; the evidence points to within one business day and at most two reminders across two weeks. Exhibitors get until the second or third working day, because on the last afternoon they are dismantling a stand.
What is a good response rate for a post-event survey?
Between 10 and 20 percent for conferences and corporate events, around 12 to 15 percent for live trade shows. Announcing the survey from the stage on day one, and saying what last year’s feedback changed, is what moves a rate above that band.
Which survey results should go to the board?
Four numbers, decided in advance: exhibitor likelihood of return, meeting completion rate, buyer relevance rating, and NPS reported separately per audience. Segment by stand size, first-time versus returning, and meetings held before you present.
Should exhibitors and visitors get the same survey?
No. Exhibitors judge the event by leads and meetings, visitors by relevance and time well spent. The industry’s own benchmark providers keep the two apart, and a combined score cannot be compared with anything.
Three surveys, one decision
The reason to run three surveys instead of one is not thoroughness. It is that the person who has to sell next year’s floor space needs an answer that a blended satisfaction score cannot give: did the meetings do their job? Visitors, exhibitors and speakers each hold one part of that answer, and they hold different parts.
Split the surveys, send them on their own schedule, ask about the meetings rather than only about the mood, and set a segment floor before anyone builds a slide. What comes back is not a report card on how the event felt. It is the evidence your commercial team takes into the renewal calls, which is the only version of post-event feedback that pays for itself.
If you want to see how meeting data and post-event feedback fit together in one system rather than two spreadsheets, get in touch with Converve. We will walk you through what our hosted buyer and matchmaking setup records during the show, and what that leaves you to ask afterwards.
