Your questionnaire is finished, the link is live, and three days later you have 14 responses. Finding survey participants is the point where most surveys stall, and the questionnaire is rarely the reason.
Survey participants come from five channels: your own circle, subject groups on social networks, survey exchange platforms, the direct route through an institution such as a university, a club or an employer, and a QR code where your audience already is. Your target group decides which channel is worth the effort, not the speed. We show you what each one does to your sample, so that nobody picks your recruitment apart at the end.
📌 The key points at a glance
- Your own circle answers fast and rarely matches your target group.
- Exchange platforms bring point collectors, not people who care.
- Prize draws are the weakest incentive form: conditional and not monetary.
- A prize draw email address makes your survey pseudonymised.
- How you recruited belongs in the methodology chapter of your dissertation.

Find survey participants: which route fits your survey
The right route depends on a question you answer before you start looking: do you want to test a relationship between two variables, or do you want to say what percentage of a group thinks something? Selection problems are awkward for the first goal and fatal for the second.
People who decide for themselves whether to take part form a self-selected volunteer sample. Nothing in such a sample supports a statement about “all students” or “our customers”, not even with 800 responses. For testing a hypothesis in a dissertation, a self-selected sample is usually accepted, provided you say so plainly in the write-up.
The second question sounds trivial and gets skipped anyway: where does your target group already spend time? Everything else follows from that answer.
| Channel | How fast | What it is good for |
|---|---|---|
| Your own circle | hours | the pretest and your first responses |
| Subject groups on social networks | one to three days | clearly defined interest groups |
| Survey exchange platforms | days to weeks | students and broad general topics |
| University, club, employer | days to weeks | precisely defined target groups |
| QR code on site | hours to days | places your audience already visits |
How large your sample has to be depends on your analysis, not on the channel. We work through the numbers in the guide to the representative survey.
Your own circle: fast, but one-sided
Friends, family and coursemates are the fastest channel, because you can ask them directly and nobody has to build trust first. For your first twenty responses that is the right move, and for the pretest it is the only sensible one.
The catch is similarity. Your own circle resembles you: similar age, similar region, similar education, often the same course. Those are exactly the variables you want to vary in your analysis. A survey that is three quarters your own seminar group measures your own seminar group.
Use your circle deliberately as a test run. Ask three people to complete the questionnaire and then tell you where they hesitated. Three honest testers find more problems than any amount of rereading. Sharing the link in messenger groups afterwards is covered in the guide to running a survey on WhatsApp.
💡 Tip
Message your three testers individually, never in a group chat. In group chats everyone waits for somebody else to go first, and nobody does.
Social networks and subject groups: where your audience already is
Social networks deliver participants when you post in groups built around your topic, not in groups built around surveys. The difference decides whether your dataset is worth anything afterwards.
A post on your own timeline reaches roughly the people you have already asked. The interesting places are where your audience sorts itself by subject: the Facebook group for allotment holders, the forum for physiotherapists, the Reddit board for your topic, the LinkedIn group for procurement. People there are affected by your question, and they answer differently from somebody collecting points.
What makes the difference in practice
- Read the group rules before posting, because many groups ban surveys outright.
- Name your target group in the first line, so the wrong people never click.
- Approach working professionals on weekdays, not at the weekend.
- Answer questions in the comments, which keeps the post visible.
- Send one reminder after five days, and only one.
Naming your target group in the first line feels like giving away reach. In practice the opposite happens: people who do not qualify never click, never drop out halfway and never dilute your data. Partial responses are what makes every later analysis painful.
Survey exchange platforms: what you trade away
Survey exchange platforms run on reciprocity: you complete other people’s questionnaires, collect points, and spend those points on responses to your own survey. Give a lot and you get a lot, and the mechanism works surprisingly reliably.
The limit sits in the same place. On the other side there is almost always somebody writing their own dissertation and short of points. Your sample then consists of students who care about the exchange rate, not about your subject. Methodologically that is a self-selected volunteer sample, with every limit that comes with it.
One simple decision rule follows:
✓ Your target group is students or a broad general public
✕ Your target group is a specific profession, industry or age band above 40
→ In the second case the platform costs more time than it returns
Look closely at the data if you do use one. People clicking for points click fast: the same answer down a whole matrix, completion times far below everyone else, not a single open text answer. Cases like that should be excluded with a stated reason, and the reason belongs in your write-up.

Institutions and offline: the route most people forget
Going through an institution hands you exactly the target group you need, because somebody there has already made the selection for you. Your Students’ Union and your course reps know everyone on the course, a club knows its members, an HR team knows every employee.
What you need in return is a request that creates no work for the other side. Send a finished text to forward, the link, the length in minutes, your supervisor’s name and the closing date. Anyone who receives an email they only have to forward will forward it. Anyone asked to write something first will not.
Print is the second route. A QR code on a noticeboard, on a lecture slide, on the bar at a club event or on a flyer reaches people exactly where your topic touches them. At empirio.ai, an online survey tool from Germany, you can create a QR code without needing any extra software. What matters when printing and scanning is set out in the guide to running a survey with a QR code.
⚠️ Watch out
Surveys that run through an employer, a school or a public body follow that organisation’s own rules. Approval before sending is the norm, and purely private surveys are the exception. Your organisation’s data protection officer decides, or at university your supervisor or the research ethics committee. Everything else that applies to data protection in surveys is covered in a separate guide.
Prize draws and other incentives: where most guides get it wrong
The raffled gift card that appears in almost every sample invitation online is the weakest incentive form survey research knows. A prize draw is not monetary, and it is conditional on taking part. Both properties reduce the effect.
Anyone running a survey in the UK has a clear benchmark for handling incentives. The Market Research Society sets it out in the MRS Code of Conduct 2023, operative from 15 May 2023. Rule 26 requires that where incentives are offered, participants are “clearly informed: a) who will administer the incentive; b) what the incentive will be; c) when the participant will receive the incentive; and d) whether any conditions are attached e.g. completion of a specific task or passing of quality control checks”. The comment on the same rule is blunt: “Incentives that require participants to spend money to be redeemed, e.g. money-off vouchers, are not permitted.”
The Code binds MRS members, so it is not law and it does not bind you as a student. As the professional standard for research in the UK it is still the sensible benchmark, and a supervisor who asks how you handled your incentive will recognise it.
How big the difference between incentive types is
Several meta-analyses put numbers on the gap. Klaus Pforr summarises them in the GESIS Survey Guidelines on incentives (2015), a German-language source. Church (1993) analysed 38 postal studies and found that unconditional cash incentives raised response rates by 19 percentage points, while gifts raised them by 8. Edwards and colleagues (2002) covered 292 studies and report that unconditional incentives increase the odds of participation by 71 percent compared with conditional ones. For web surveys the effect is smaller: Göritz (2006) finds a gain of around 20 percent.
The figures come mostly from postal surveys and do not transfer one to one to your online survey. The ranking of the incentive types holds, though. And one point weighs more than any response rate: an incentive helps data quality only if it raises response without making non-response more selective. A voucher that mainly attracts people with little money and plenty of time buys you more answers and a more lopsided sample.
A prize draw and anonymity cannot share one form
A prize draw needs a way to contact the winner, usually an email address. Collecting that address in the same questionnaire ends the anonymity of the survey, whatever the invitation promised, because every response now sits next to an identifier.
The Information Commissioner’s Office is precise about the consequence. In its guidance Introduction to anonymisation the ICO writes: “It is common to refer to datasets as ‘anonymised’ when in fact they still contain personal data, just in pseudonymised form. This poses a clear risk that you might fail to comply with data protection law.” And further down: “Remember that if you can still identify people using additional information you hold separately, the data is not anonymised. It is pseudonymised and is still personal data.” Your responses then fall under the UK GDPR and the Data Protection Act 2018 exactly as before. MRS Rule 49 points the same way and asks members to preserve the anonymity of participants unless they have given informed consent for their details to be revealed.
Separating the two forms fixes the problem. Put a second, separate link on the thank you page leading to a form that collects nothing but the address for the draw. The two datasets keep no connection, and the survey itself stays an anonymous survey. Whether your project needs anything beyond that is decided by your university research ethics committee or your supervisor, or by the data protection officer in your organisation.
What works instead of a prize draw and costs nothing
An incentive never replaces a reason. Four things beat five raffled gift cards in practice: a questionnaire under five minutes, a named person instead of a bare link, one sentence on what the results will be used for, and an offer to send the findings once you are finished. The last one costs you an email and is often the most persuasive argument in a subject group. This guide is not legal advice.
The invitation: five things people need before they click
An invitation to a survey needs five pieces of information: who it is for, what it is about, how long it takes, what happens to the data, and the closing date. Anything beyond that is decoration, anything below it costs you responses.
Length is the point most often estimated and least often measured. “Only takes 5 minutes” appears in nearly every appeal, and when it turns out to be twelve, people abandon the form and you are left with partial records. Complete your own questionnaire once with a stopwatch, then quote that number plus a buffer. Add the number of questions, which reassures people more than any minute count.
An opening that works looks like this
Have you bought a bicycle in the past twelve months? 14 questions, about four minutes, anonymous, for my dissertation at the University of Manchester. Open until 15 October.
The first sentence filters, the second removes every excuse. People who do not qualify stop reading, which is exactly the intended outcome. Building the right questions behind that link is covered in the guide to creating a questionnaire.
Common mistakes when recruiting participants
People short of responses usually go looking for another channel. The problem often sits somewhere else entirely, in one of the following four places.
All four mistakes share one trait: they surface only once the survey is already running, and from then on they are expensive to repair.
You look for participants when the questionnaire is the problem
Many people open the link and few reach the end, and no extra channel fixes that. The questionnaire is losing them, usually at a compulsory question, a long matrix or the third page. Find out which question the drop-offs happen on. At empirio.ai the drop-off rate shows you precisely that, from the Lite plan upwards (as of August 2026).
You post everywhere at once and cannot tell what worked
Spreading the link across eight groups in one afternoon leaves you unable to say where the responses came from. For the analysis that is a loss, because the source often explains the differences in the data. Add a short question instead: “How did you come across this survey?” Ten seconds of your respondents’ time saves you a paragraph in the methodology chapter.
You either never remind people or remind them constantly
A single reminder after about five days almost always produces a second wave, because plenty of people saw the link, meant to take part and then forgot. Two reminders feel pushy, three annoy. Keep it short, avoid any reproach, and repeat the closing date.
You do not write down how you found your participants
Recruitment belongs in the methodology chapter, not in a footnote. Anyone recruiting through friends, groups and exchange platforms has collected a convenience sample, and the write-up should use that term. Add one or two sentences in the limitations on what that means for the reach of your findings. A supervisor who misses it deducts marks. A supervisor who finds it sees somebody who understood their own method.
Conclusion
Too few participants is usually a target group problem, not a reach problem. The fastest channels produce the most lopsided samples, and the slow route through an institution often delivers precisely the people your question is about. Find the place your audience already occupies first, then pick the channel.
One limit belongs in the same breath: empirio.ai does not supply participants. No panel and no community exists that you could draw responses from. The tool handles everything before and after, from the questionnaire to the analysis, and finding people stays your job.
