Online Bulletin Board in Research: How It Works, When to Use It

An online bulletin board is a private, moderated online forum where research participants answer a researcher's questions and tasks over several days, at times that suit them. It is asynchronous: nobody has to be online together. Tasks can ask for text, photos or video, and participants can usually read and reply to one another.

You will also see it called an online discussion board or, loosely, an asynchronous focus group. An online research community (MROC, short for market research online community) is different. A board is time-bounded around one research question, while a community usually runs longer as an ongoing group.

A board runs as a short sequence: briefing, daily prompts from the moderator, participant replies, moderator probes on those replies, and a wrap-up. The schedule below is illustrative, not a Qualfacto specification. Your research question sets the real length.

Sample tasks (also illustrative):

• Text reflection: "Describe the last time you bought this. What happened next?"
• Photo upload: "Photograph where you keep it at home and say why."
• Short video: a 30-second clip showing how you use it.
• Concept reaction: read a concept card, then say what is clear, what is unclear, and what you would change.

A probe is a follow-up question on one person's reply, such as "What made you choose that one?" Probe enough to build trust, but not so much that you steer the group (Bain). The moderator also chases participants who fall behind with a short, friendly nudge, because follow-up keeps the board complete (Fieldwork Hub).

Pro tip: Ask participants to finish early. Pew offered a prize draw to those who completed everything by Wednesday of a Monday-to-Friday week, leaving time to probe (Pew Research Center).

Published sources do not agree on one typical board, so treat the figures below as ranges. Participant numbers run from 15–20 per board to 300 or more in multi-market studies, and length runs from two days to several weeks, with some boards lasting up to three months. These are industry ranges, not Qualfacto specifications.

The sources differ, and scope is agreed per project.

Corona Insights ties its typical 15–20 participants to the moderator not having to be present all the time, which also lets one moderator run more than one board (Corona Insights). Larger numbers appear in multi-market studies (Indeemo). Whatever the size, expect some participants to go quiet, so plan extra recruits (see the India section below).

For general reasoning on numbers, see sample size in qualitative research.

Choose an online bulletin board when answers need thought, respondents are spread across cities and schedules, and you can do without watching reactions form. Otherwise pick a live group, an interview or a diary study, as below.

The 1–3 hour and 30–120 minute figures are our own formats; our diary studies are multi-day photo and video tasks on a mobile app or the web.

Rule: need to watch a reaction form, run a live group (see online vs in-person focus groups). Need one person's story, run an interview (the in-depth interview method). Need behaviour in the moment, use a diary; our guide to diary studies explains when a diary beats an interview. A board often complements these rather than replacing them.

A board fits when time to think improves the answer: considered opinions, topics that unfold over several days, respondents in different cities or time zones, sensitive topics, and reviews of visual material. Reasons to choose it:

• Considered answers: replies are not time-pressured, so they tend to be more reflective (Corona Insights).
• Multi-day topics: feedback builds over days, as in product use.
• Spread-out respondents: schedules and distance matter less.
• Sensitive topics: people often feel more comfortable sharing real views when they are not face to face (Indeemo).
• Visual stimulus: participants can look at images or concepts calmly and respond in detail.

Use cases named by the sources:

• Concept or creative testing: testing creative material before launch (Fieldwork Hub); Bain describes a three-day concept sequence.
• Product trial feedback: send samples and collect feedback over time (Bain).
• Journey pain points: understanding customer journeys and their pain points (Fieldwork Hub).

A board does not fit when you need live reaction, when your audience cannot type or stay connected comfortably, or when you expect thin replies you cannot fix. Then use a live method.

• Live reaction: the biggest drawback of a board is the loss of non-verbal cues (Bain). If a facial reaction is your data, run a live session.
• Low literacy or low connectivity: in Pew’s Spring 2025 survey in India, 36% of adults said they did not use the internet at all. Pew’s 2023 survey (fieldwork 25 February to 22 May 2023) shows the age gap: fewer than half of Indian adults owned a smartphone, and 73% of under-40s used the internet against 36% of those aged 40 and over. The two 36% figures come from different surveys and questions. For older or lower-connectivity audiences, we recommend interviews, possibly in person.
• Thin responses: boards have less participant-to-participant exchange than live groups (Corona Insights). Write tasks that ask for an example or a story, not yes or no, and probe early.

Running a board in India comes down to four decisions made before fieldwork: which cities, which languages, how tasks work on a phone, and what participants are paid and told. Our recommendations follow; none come from a published benchmark.

Languages and Mobile-First Participation

Let participants reply in the language they think in. We recommend allowing mixed-language posts, planning translation time up front, and using a moderator who reads the language.

Design for a phone first. Keep each task to one screen of reading, ask for photos taken on the camera, and keep videos short. Test the board on a basic phone over mobile data before launch.

Recruitment, Incentives and Identity Checks

Recruit by city quotas written into a screener (the questionnaire that decides who qualifies); see research screeners. Identity checks before invitation reduce fake or duplicate participants.

Recruit extra people, since not everyone stays engaged (Drive Research advises budgeting for this). In the Pew board, 60 people were recruited and 57 completed it.

Pay incentives in stages for longer boards (Fieldwork Hub). Agree incentive terms before the study, and release each payment once the matching participation requirements are completed and validated.

Because participants can read each other's posts, consent for a board must say who will see what, before anyone posts. Under the Digital Personal Data Protection (DPDP) Act, 2023, personal data processing needs a notice and consent that is free, specific, informed, unconditional and unambiguous, and consent can be withdrawn (Act text, MeitY).

As of October 2026, the DPDP Rules, 2025 (notified 14 November 2025) are being phased in over 18 months, so most obligations, including notice, apply from about May 2027 (PIB).

• Public and private tasks: a moderator can set questions so everyone sees the replies, or only the participant and moderator do (Corona Insights).
• Blinded replies: participants cannot see others’ comments until they have posted their own (Bain). This limits groupthink.
• Informed consent: state purpose, visibility, recording and withdrawal; see informed consent.
• Anonymised handling: we recommend first names or usernames on the board, and exports with identifiers removed. Pew’s board kept participants’ names private from other participants and out of its reports (Pew Research Center).

A buyer receives what the agreed scope includes. We agree on deliverables, file formats, and responsibilities before the study begins. Depending on scope:

• Participant recruitment
• Transcripts
• Recordings
• Structured data exports
• Research reports

Share a brief with us. We review the objective, method, audience, geography, sample size and timelines, check feasibility, then send a tailored proposal and quote. Pricing is set per project, with no fixed rate card. Once scope, commercials and timelines are agreed, recruitment begins.

On top of the market research brief, add these board fields:

• Reply languages and cities
• Daily time you ask of participants
• Task types: text, photo, video
• Whether participants may see each other's posts
• Consent and incentive terms
• Deliverables

Email support@qualfacto.io (Monday to Friday, 10:00 to 18:00 Indian Standard Time, IST); we aim to reply within one business day.

Use an online bulletin board when people need time to think, live in different places, and can type comfortably on a phone. Choose a live method when you need to watch a reaction form, or when your audience has low connectivity or finds typing hard.

Published sources disagree on board size and length, so agree on both for your own question. In India, settle city quotas, reply languages, phone-first task design, and consent and incentive terms before fieldwork.
