An online bulletin board is an asynchronous qualitative study where respondents return over multiple days to answer questions, view stimuli, and often share photos, video, or audio, without needing to be online at the same time. Think of it as a guided diary or a private online discussion space that unfolds over several days. Researchers use it to understand why people think and act the way they do.
A short history
Bulletin boards began in the early days of online research as simple text discussion forums moderated by researchers. Over time the format grew to include images, video, and mobile access. Today it is one of the highest-signal qualitative formats because it combines depth, real-life context, and flexible scheduling.
How a board works
- 1Researchers recruit a small group, often 10 to 40 people.
- 2They design a study across days, such as 3, 5, or 7.
- 3Each day, respondents get a short set of questions or tasks.
- 4Moderators read answers and ask follow-up questions.
- 5At the end, researchers analyze themes and write the story.
The key terms you will hear
- Asynchronous: people take part at different times rather than together.
- Moderator: the researcher who reads answers and asks follow-ups.
- Stimulus: anything shown to respondents, such as a concept or ad.
- Probe: a follow-up question that digs deeper into an answer.
- Day unlock: a rule that makes the next day’s tasks available at a set time.
- Coding: tagging answers with labels to find themes.
Why boards still win
- Time for reflection
- Geographic reach
- In-context media
- Lower scheduling tax than groups
- More thoughtful, written answers from people who might be quiet in a group
What boards are used for
- Understanding daily routines and habits
- Exploring reactions to concepts or advertising
- Shopping and usage diaries
- Pre-work before a focus group
- Following change over days after a trial
Limits to be aware of
Boards depend on people being willing and able to write or record answers, so they can underrepresent those who find that difficult. Answers take time, so boards are not instant. Small samples mean results are not statistically representative. Good design addresses these limits with short tasks, voice or video options, and careful recruitment.
Boards compared with other methods
| Method | Main strength | Where a board adds more |
|---|---|---|
| Survey | Measures at scale | Explains the reasons behind the numbers |
| Focus group | Social interaction | Adds real-life context and reflection over time |
| In-person interview | Rich one-to-one depth | Works across places and time zones without travel |
Example: a team studying evening snacking sets up a four-day board. People share what they eat, take photos of where they snack, and react to a new product idea. The researcher follows up on interesting answers each day.
