Running trade show marketing customer interviews without leading the witness

What to take away

Set the inclusion criteria first

Before booking anyone, write down who counts as a customer. For most England exhibitors that means people who attended a UK trade show in the past 18 months, hold or influence budget, and work in your target sector. Exclude colleagues, competitors and agencies selling to you.

Geography matters because attendance patterns differ. A buyer who travels to ExCeL London may never attend a regional show in Manchester or Harrogate. Decide whether you are researching one venue's audience or a national pattern, and say so in the recruitment email.

The same discipline applies across the wider programme. Our trade show marketing audience research guide for England sets out how interviews sit alongside desk research and stand observation.

Recruit without a paid panel

Pull 40 to 60 named contacts from your CRM, quote requests and stand scans. Send an invitation stating the purpose, the 30 minute duration and whether a voucher is offered.

Expect a low response. For example, a team emailing 60 past visitors might book 10 interviews, which is enough for qualitative work. Do not call that representative of a market.

Ask about the last show

Hypothetical questions produce polite fiction. Ask the interviewee to walk you through the last event they attended: how they decided to go, who they travelled with, and which stands they stopped at.

Then probe the friction. What made them walk past a stand? What did they need to see before leaving a card?

Keep questions open and neutral. "What nearly stopped you booking a meeting?" works better than "Would a bigger stand help?", which invites agreement.

Handle consent and claims properly

Interviews collect personal data, so tell people what you will do with the recording, how long you will keep it, and how they can withdraw. The ICO's direct marketing checklist is a sensible reference for auditing how you store and reuse those notes.

Anything you later publish as a claim needs to be defensible. The ASA and CAP regulatory framework explains how advertising claims are assessed, which matters if interview quotes end up in campaign copy.

Venue logistics also shape what you can promise. The HSE industry guidance covers health and safety duties for exhibition venues and events, so check it before promising a demonstration area.

If you gather answers at scale instead of in calls, the trade show marketing survey tools in England comparison covers platforms that record consent as well as responses.

Turn notes into stand decisions

Code each transcript against three headings: barrier, proof and route. You are looking for the reasons people hesitate, the evidence that removes doubt, and the way they prefer to continue the conversation.

Once eight transcripts are coded, count how often each theme appears. A theme raised by five or more interviewees is worth acting on. A single vivid comment is not.

A worked example

An illustrative example: a machinery supplier in the West Midlands books an 8m by 6m stand at a regional show with a total budget of £18,000. It allocates £1,200 to interview incentives, at £50 per person across 12 interviews, plus £400 for transcription and £600 of internal time.

The interviews reveal that visitors cannot judge machine compatibility from photographs. The supplier moves £2,500 from printed brochures into a live demonstration slot and a comparison board. Nothing else on the stand changes.

Those pound figures are illustrative, not benchmarked. Your venue contract, stand build and staffing costs will set the real numbers.

Common questions

How many interviews are enough?

For qualitative work, eight to twelve interviews usually surface the main themes. Stop when new conversations repeat what you have already heard.

Should I pay interviewees?

A modest voucher is common and improves attendance. Check your procurement rules and record the payment, because incentives are business expenditure.

Can I reuse quotes in marketing?

Only with permission covering the specific use, and only if the claim is accurate. Written consent in the recruitment email beats a verbal yes on the call.
