What's the best way to find participants in terms of budget, time and quality of results? The answer lies in survey platforms. That's a space dedicated exclusively to the survey exchange, so people come there with a strong purpose and will to fill out your questionnaire. Additionally, survey platforms provide time control and other features that prevent biases in collected data. They also help to identify unreliable participants.
Of all the survey platforms available, we recommend the use of PoolPool. Here, you can create, share and get participants for free. The rule of thumb is that you need to respond to other surveys. In addition, Pool Pool offers time and other controls to help you reach the best quality of your answers. Pool Pool is a family-like community that brings together students and small business owners. This means it's easy to navigate, which sets us apart from other competitors.

Beyond the survey platforms, do not shy away from maximizing your chances of getting answers via social media. But be wise about it: join Facebook survey exchange groups (here and here), your university forum, or any other major community (such as Quora, or TheStudentRoom). That way, you're reaching out to people from groups that you wouldn't necessarily connect with otherwise.
So here's another strategy: put your research flyers all over campus. This may attract some people, especially if you are offering some sort of reward for participation - a voucher to a store or small cash compensation. But again, it's hard to reach a large group of people this way, and you can go broke in the process.
Regardless of which method you choose, give yourself plenty of time to gather the required number of responses. Always gather a bit more than you need, in case some participants won’t be fit to constitute as data.
And that’s it! If you still have doubts about your questionnaire, check our other articles, namely, how to clean out your survey data or why does no one want to answer your questionnaire.
