Key takeaways
- The fastest respondents are your own users and paid sources, but speed is only useful with quality controls built in before launch.
- Use completion codes, attention checks, honest screeners, minimum times, and one response per person, and decide the rules before you see any data.
- Incentivized respondents are not a representative sample. Use them for directional answers, usability, and concept tests, not to estimate population figures.
How do you get survey respondents fast?
To get survey respondents fast, start with people who already know you, such as your users, customers, and email list, then add paid sources when you need more answers or a specific audience: research panels, or a paid task that asks people to complete your survey and submit a completion code. Whatever the source, build quality controls into the survey before launch, because fast responses are only useful if you can trust them.
Before you start: who and how many
Two questions decide which sources make sense.
- Who must answer? “Anyone who shops online” can be reached almost anywhere. “IT managers in companies over 500 people” needs a specialized panel or your own network.
- What will you do with the answers? If you want to estimate a figure for a whole population, such as the share of people in a country who own a product, you need a sample that represents that population. If you want to find usability problems, compare two concepts, or collect ideas, a convenience sample of the right kind of people is usually enough.
For a simple random sample, the standard formula says that about 385 responses give a margin of error of roughly plus or minus 5 percentage points at 95% confidence for a yes or no question. That math only holds for a random sample. It does not make a self-selected or rewarded group of respondents representative, however many of them answer.
Where to find survey respondents
1. Your own audience
Customers, users, newsletter subscribers, and social followers are the cheapest and often the most relevant respondents. Send a short, personal email, add a link in your app or on your site, or show a one-question survey at a natural moment, such as after a completed order. Keep it short, say how long it takes, and send one reminder at most.
The limit: your audience already likes you enough to be there, so it tells you little about people who chose a competitor or never heard of you.
2. Social media and personal networks
Sharing the link on your profiles, and asking colleagues to share it, can bring the first few dozen answers in a day. The answers skew toward people like you and your followers, so this works for early exploration rather than for conclusions.
3. Communities and forums
Niche subreddits, forums, Discord servers, and professional groups can reach exactly the people you need, and some have dedicated threads for surveys. Read the rules first, ask a moderator if in doubt, explain who you are and why you are asking, and share the results with the community afterwards. That last step often doubles the goodwill for the next survey.
4. Research panels
Panel providers maintain pools of people who have agreed to take surveys for a reward and have already given basic profile data, so you can target by country, age, or occupation. They are the most reliable paid option for hard-to-reach groups and come with their own quality checks, but they are usually the most expensive per complete and often have minimum orders.
5. Paid incentives for your own respondents
A small reward for each completed response, or an entry into a prize draw, raises response rates from your own audience. Keep the reward modest so it does not attract people who only want the reward, and check the local rules for prize draws in the countries you run them in.
6. Paid tasks on an offerwall
Per-result platforms let you post a task such as “Complete our 8-minute survey and enter the completion code”. Users of the publishers’ sites and apps choose the task and are rewarded by the publisher, and you pay per completed response. You set the countries, the device types, and the price, and you can reject responses that arrive without a valid code. This is fast and flexible, and it is incentivized, so the quality controls below are essential.
| Source | Speed | Cost | Targeting | Main risk |
|---|---|---|---|---|
| Your own audience | Fast | Free or low | Only people who already know you | Biased toward fans |
| Social and personal network | Fast, then stalls | Free | Weak | Respondents similar to you |
| Communities | Medium | Free, costs time | Good, by topic | Rules, small numbers |
| Research panels | Fast | Highest per complete | Detailed profiles | Budget and minimums |
| Offerwall tasks | Fast | Per result, you set the price | Country, device, OS | Low-effort answers without checks |
Quality controls that make fast answers usable
Decide these rules before launch, write the ones that affect respondents into your instructions, and apply them the same way to everyone.
- Completion codes. Show a code on the last page of the survey and ask for it as proof. A unique code per respondent is much stronger than one shared code, which can be passed around. Many survey tools can show a random ID or a response ID on the end page; match it against your response list.
- Attention checks. Add one or two instructed items, such as “For this question, select Disagree”. Keep them fair and clearly worded, and avoid trick questions that honest people fail.
- Screen-out questions. If you need a specific group, ask qualifying questions first, and do not reveal the qualifying answer. “Which of these pets do you own?” with several options works better than “Do you own a dog?”. Respondents who screen out should reach an end page that says so.
- Time minimums. Time yourself and a few colleagues reading the survey at a fast but honest pace. Flag responses that are far faster than that, and pick the cut-off before you look at the results.
- Open-ended checks. One short open question, such as “In one sentence, why did you choose that option?”, makes copied or random answers easy to spot.
- Consistency checks. Ask the same thing twice in different words, for example age range at the start and year of birth at the end, and flag contradictions.
- Country targeting. Limit the survey to the countries you are studying, and ask for country in the survey as a cross-check.
- Duplicate prevention. Allow one response per person: turn on your survey tool’s duplicate protection, and on a task platform set the frequency cap to once ever. Watch for the same open-ended answer appearing word for word in several responses.
If failing an attention check or a screener ends the survey without a code, say so in the instructions. Respondents then know the rules before they start, and you can reject a missing or wrong code with a clear reason.
How to run a survey as a paid task
Example instructions for an 8-minute product survey
1. Open the starting link. 2. Answer all questions honestly; the survey takes about 8 minutes and includes two attention checks. 3. The survey is for people who shop online at least once a month. If the first questions show it is not for you, it will end without a code. 4. On the last page, copy the completion code. 5. Enter the code in the text field. Proof requirement: the completion code from the last page of the survey, exactly as shown.
Text proof is the right choice here, because a code is short and you can look it up in seconds. Pair it with a once ever frequency cap, a total budget, and a daily cap that matches how many responses you can check within your approval window. Proof requirements by task type explains the proof types and their limits, and Write instructions that pass review covers the instructions.
When you review, judge the code and the rules you wrote, never the opinions. Rejecting a response because you dislike the answer is unfair and breaks the trust that keeps careful respondents coming back. Reject codes that do not exist, codes already used, and responses that clearly fail the checks you announced.
Ethics and disclosure
- Say who you are and what the survey is for, on the first page.
- Be honest about length and about screeners that may end the survey early.
- Make participation voluntary, let people skip questions they do not want to answer where possible, and explain how answers will be stored and used.
- Collect only what you need. Do not ask for names, email addresses, phone numbers, home addresses, ID numbers, passwords, payment details, or sensitive data such as health information, unless the study truly needs it and you handle it under the data protection rules that apply to you. For most product and market surveys, none of it is needed.
- Do not use a survey as a disguise for collecting leads or selling something.
- Follow your platform’s data rules. On Sharklio, completion details may be used only to review and measure the campaign, never to contact or profile respondents outside the offer.
- Check whether you need ethics approval. Academic and medical research often requires review by an ethics board before you collect any data.
The honest limits of incentivized respondents
People who take surveys for rewards are a self-selected group. They tend to be more online, more experienced with surveys, and more motivated by the reward than the average person in their country. That does not make their answers worthless, but it does limit what you can conclude.
Good uses: usability feedback (see How to get website feedback for page-level questions), first reactions to a concept or a message, comparing two versions of a landing page or a name, finding the questions in your survey that confuse people, and directional reads on preferences among people who match your screener.
Poor uses: market sizing, population estimates, polling, or any claim of the form “X% of people in country Y”. For those, use a provider that offers properly designed and weighted samples, and say clearly in any published result how respondents were recruited. Incentivized traffic explained covers rewarded users more generally.
Collecting survey responses with Sharklio tasks
A Sharklio task campaign can ask users to complete your survey from a starting link and send the completion code as text proof. You choose the countries, devices, and bid, starting from $0.01 per approved completion, set the frequency cap to once ever, and see each submission with its country, device, and the time from start to submission before you approve it. You pay only for the completions you approve. You can create a free account and your first campaign today, and Set bids by country helps you price it.
Frequently asked questions
What is the fastest way to get survey respondents?
Your own users or customers, if you have them, and paid sources such as research panels or offerwall tasks if you need more answers or a specific group. Paid sources can deliver responses within a day, as long as your quality checks are ready.
How many survey respondents do I need?
It depends on the goal. For finding usability problems or testing a concept, a few dozen relevant respondents can be enough. For estimates about a whole population, you need a properly drawn random sample, and the margin of error formula applies only to that kind of sample.
What is a survey completion code?
A code shown on the last page of a survey that respondents enter as proof that they finished. Unique codes per respondent are best, because a single shared code can be passed around.
Can I reject survey responses I do not agree with?
No. Reject only when the proof fails the rules you stated, such as a missing, invalid, or reused code, or a failed attention check you announced. Opinions are the point of the survey.
Are paid survey respondents reliable?
They can be, with completion codes, attention checks, screeners, time minimums, and one response per person. They are not a representative sample of the general population, so use them for directional answers rather than population estimates.
