Why Event Feedback Matters: Before, During and After Your Event
Event feedback is most useful when you collect it at three points: before you plan, while the event is running, and after it ends. Here is what to ask at each stage and how to act on it.

Event feedback is the cheapest research you will ever do. The people who attend your events already know what would make them come back, what nearly made them leave, and what they would tell a colleague. The organizers who improve year on year are usually the ones who ask at three points: before they plan, while the event is running, and after it ends. This guide covers what to ask at each stage, how to ask it without annoying anyone, and how to turn the answers into decisions.
Why event feedback matters more in 2026
Attendees have more choice than they used to, and they decide quickly. In Encore and Boldpush's research, What's shaping live experiences in 2026, connection drives 49% of attendance decisions. If people come for connection, you need to know whether they got it, and only they can tell you.
Sponsors care too. The same Encore report found that events that measure outcomes keep 71% of their sponsors, while those that don't keep 52%. Feedback is a large part of measuring outcomes: it gives you something concrete to put in front of a sponsor at renewal time, beyond a headcount.
Finally, feedback protects your reputation as an organizer. Every event is a sample of your work. Asking, listening and visibly changing things is how a one-off attendee becomes a regular.
Before the event: ask before you plan
Some people call this pre-event feedback; really it is research into what the event is for, who it is for, and what they expect. You won't predict success from a survey, but you will learn what to include and what to leave out.
Who to ask
- Past attendees. They know your format and can compare.
- Your target audience who haven't come yet. They can tell you what has kept them away.
- Speakers and sponsors. They see the event from a different angle and often spot logistics problems early.
What to ask
- Which dates, times and locations work, and which rule them out.
- What kind of venue they prefer: city center, campus, hotel, somewhere unusual.
- Which topics, speakers or formats they want (talks, workshops, roundtables, unstructured time).
- What problem they hope to solve by attending.
- What a ticket is worth to them, if the event is paid.
Keep it to five to eight questions. A short survey that people finish is worth more than a long one they abandon. Use multiple choice for anything you will need to count, and one open question at the end for anything you didn't think to ask.
Your registration form is a second chance to learn. A question or two at sign-up, such as which sessions interest someone most, gives you planning data from everyone who registers, not only the people who answer surveys. With WebMobi, people register on your own event page rather than with a third party, so those answers and the attendee relationship stay with you.
During the event: catch problems while you can fix them
Post-event surveys tell you what went wrong. Feedback during the event lets you fix it before the end of the day.
Start at the door
Check-in is the first thing every attendee experiences. In Bizzabo's 2025 State of Events and Industry Benchmarks, 71% of attendees said ease of check-in could make or break their event experience. Watch the queue yourself in the first 30 minutes and ask staff to note every complaint.
A few things reduce check-in complaints before they happen. WebMobi QR check-in works from any phone browser and keeps scanning offline when the venue wifi drops, syncing when the connection returns. People who turn up without registering can be added at the desk and checked in in one step. Afterwards, the check-in history shows who was let in, by which staff member, on which device, and whether the scan was taken offline, which helps when you are working out where a queue built up.
Quick pulse checks
- End-of-session questions. One question ("How useful was this session, 1 to 5?") on a slide with a short link, asked by the moderator before people stand up.
- A visible wall. WebMobi's Live Wall lets guests scan a code and post a photo or message to a shared wall. It is a public channel, so it shows you mood and highlights rather than complaints, but it tells you what people are enjoying in real time.
- Staff walk-arounds. Ask volunteers to check in with a few attendees at each break: "Anything we can fix right now?" Write the answers down.
- A help point. A staffed desk or a monitored message channel gives people somewhere to report problems such as a cold room, poor audio or a missing sign.
Watch what people do, not only what they say
Attendance is feedback. If you check people into individual sessions, WebMobi's session attendance report shows who attended each one, with a CSV export. A session that empties halfway through, or a breakout that overflows, tells you something a survey might not.
After the event: the survey that shapes next year
The post-event survey is the most familiar kind of event feedback, and it becomes the pre-event research for your next one.
Timing
Send it within 24 hours, while the experience is fresh. Send one reminder two or three days later, then stop. If you have session-level data, send people questions about the sessions they actually attended.
What to ask
- Overall: How likely are you to attend again? How likely are you to recommend it?
- Content: Which session was most useful? Which speaker would you want back?
- Venue and logistics: Getting there, check-in, rooms, food, accessibility, Wi-Fi.
- Look and feel: Signage, staging, the overall atmosphere.
- Staff: Were organizers and volunteers helpful and easy to find?
- Connection: Did you meet the people you hoped to meet?
- Open question: What one thing should we change?
For ready-made question sets, see our attendee feedback survey templates and the longer guide to post-event surveys.
Don't forget the other groups
Send a separate, shorter survey to speakers, sponsors, exhibitors and volunteers. Sponsors in particular want to know you asked; their answers are the basis of next year's renewal conversation.
Feedback on your event technology
The original version of this post made a point that still holds: if attendees use an app or website to find the agenda, venue map or speaker list, you need their opinion of it, and many of them are not technical. They won't say "the navigation is unclear"; they will say "I couldn't find the room."
- Ask about tasks, not features: "Could you find the session you wanted?" "Did you know where to go next?"
- Offer simple scales and one open question rather than technical vocabulary.
- Ask staff at the help desk to log every question about the app or website. Repeated questions point to the fix.
- Test before the event. WebMobi lets you publish an event in test mode, where registrations and check-ins never count, so a few volunteers can register, check in and browse the agenda and tell you where they got stuck before real attendees arrive.
Combine what people say with what they did
Survey answers are opinions; check-in and attendance records are behavior. The most useful conclusions come from both.
| Question | What people say | What the data shows |
|---|---|---|
| Was check-in smooth? | Survey rating and comments on arrival | Check-in history by device and time |
| Which sessions worked? | Most useful session, speaker ratings | Session attendance report |
| Was the event the right size? | Comments on crowding or empty rooms | Registrations compared with check-ins |
| Will they come back? | Likelihood to attend again | Returning attendees next time |
Our event attendance reports page explains what attendance data you can pull and how to read it.
Close the loop
Feedback only builds loyalty if people can see it was used.
- Share a summary. Within a few weeks, email attendees the top three things they told you and what you will change.
- Make the change visible. When you announce the next event, say "You asked for longer breaks, so we added them."
- Keep a running log. Note each year's top issues so you can see whether fixes worked.
- Thank people. A short thank-you to everyone who responded improves next year's response rate.
If you want to put this into practice on your next event, with registration on your own page, offline QR check-in and session attendance in one place, you can create an event free on WebMobi and try it on something small first.
About WebMobi: before 2020, WebMobi’s event apps ran more than 2,000 events for over 2,000,000 attendees — among them the Boston Marathon, the Tribeca Film Festival, the NSW Department of Education and Connect ERA. More case studies.

Frequently asked questions
When should I send a post-event survey?
Within 24 hours of the event ending, with one reminder two or three days later. Response rates fall quickly after the first few days.
How many questions should an event feedback survey have?
Aim for five to ten, mostly multiple choice or rating scales, with one open question at the end. If you need more detail, send a separate, optional survey to people who volunteer for it.
Should feedback surveys be anonymous?
Anonymous surveys tend to get more candid answers about staff and speakers. If you want to follow up with individuals, add an optional box for their email rather than requiring it.
How do I get feedback from people who don't fill in surveys?
Look at behavior: who checked in, which sessions they attended, and whether they come back. Short in-person questions from staff during breaks also reach people who ignore emails.
What should I do with negative feedback?
Group it by theme, fix the issues that appear repeatedly, and tell attendees what you changed. A single complaint is worth noting; the same complaint from many people is a priority.
