Write a recruitment checklist before inviting anyone
Decide who qualifies for the session before you start finding people. For a skincare product, your checklist might specify who buys facial moisturiser, how often they use it and the price range they normally consider. For a pet product, it might require someone who owns a dog and chooses its food. Write down essential criteria separately from preferences. That gives you a consistent way to assess applicants rather than accepting whoever replies first.
Ask about recent behaviour in your screening questions
A short screening form should establish what someone actually does. Instead of asking “Are you interested in premium skincare?”, try “Which facial moisturisers have you bought in the last three months?” Follow with “Who chose them?” and “Approximately how much did you spend on the last one?” Include an honest “none” or “I do not buy this” option where relevant. Do not reveal the answer you want in the wording of the invitation.
Build a recruitment matrix, not just a guest list
Use a simple grid with one row per applicant and columns for the criteria you need to track. For example: current customer or non-customer, recent category purchase, usual spending range and relevant routine. Mark who meets the essential requirements, then select the mix of experiences your brief calls for. Keep a note of why each person was selected. The grid helps you see gaps before the session, such as hearing only from loyal customers when the project also needs new perspectives.
Check relationships that could affect the conversation
Ask whether applicants know each other, work for the client or have another connection that could make it harder to speak freely. A manager and their employee may be better heard separately. In school research, consider whether parents would feel comfortable discussing concerns in front of staff. The right arrangement depends on the topic and the relationships involved. Individual interviews may suit sensitive experiences better than a shared discussion.
Send an invitation that explains the commitment
Confirm the date, time, time zone, duration and location or video-call link. Explain what participants will do, any preparation required, whether the session will be recorded and how their contributions will be used. Set out any agreed incentive and when it will be provided. For remote sessions, check that participants have the device and connection needed for the activity. Send a reminder and a clear way to let you know if they can no longer attend.
Keep reserves and protect the information you collect
Identify suitable reserve participants and explain clearly whether they are on standby or have a confirmed place. Collect only the information needed for recruitment and coordination, limit access to the recruitment list and agree how long it will be kept. Share the agreed audience criteria with the moderator before the session so that the discussion reflects the people actually attending. Avoid promising anonymity where group members will be able to see and hear one another.
Already have participants? Start with what you know
Recruitment is only one part of a focus group project. If your school or business already has a group, document who is attending and their relationship to the organisation. DN Insights can help remotely with discussion questions, recording review, transcription and analysis. For school projects, that can include bringing together parent feedback from sessions you organise yourself. Your audience brief should reflect that community rather than defaulting to a consumer-product profile.
