In-person or online focus group: when each one makes sense
An in-person focus group makes sense when the stimulus is physical, when the real group dynamic matters, or when you want reactions that don't come through a screen. An online one makes sense when people are far apart, when the profile is hard to gather in one city, or when time is short. It is not a question of which is better, but of what your decision needs.
When in-person makes sense
- There is something to touch, try or walk through: a car, a package, a store, a food.
- The conversation between people is part of the finding: how they persuade each other, where they contradict each other, what they say once someone else has said it.
- Body language matters: a face on seeing a price, the hesitation before an answer.
- You want the brand to listen live, seated at the table or behind the room.
When online makes sense
- People are spread out across several cities or countries.
- The profile is scarce or short on time, such as executives or specialists.
- The topic is easier to discuss from home, or the presence of the group inhibits people.
- Time is short and there is no time to book a room.
Quick comparison
| In person | Online | |
|---|---|---|
| Physical stimulus | Yes | Limited to what shows on screen |
| Group dynamic | Complete | More orderly, less spontaneous |
| Geographic reach | One city | Anywhere with a connection |
| Knowing who said what | Hard with a room microphone; clear with one microphone per person | The platform usually marks who is speaking |
| Logistics | Room, travel, reception | Links, tech checks |
What about interviews run by an AI?
There are now tools in which an AI interviews one person in front of a screen. They are good for volume and speed, but they are not a focus group: there is no group, no room and no physical stimulus. They are a different tool for a different question.
The weak spot of in-person groups, and how to fix it
In a room, each microphone hears the neighbors better than its wearer. We measured it in a real focus group: in a two-minute window, the owner of a microphone was the loudest voice on her own microphone only 11 of 120 seconds. That is why in-person reports misattribute. The fix is one microphone per person, synchronized with a camera that sees the whole table. We explain it in how to know who said what in a focus group.
