An online survey is a questionnaire that the target audience can complete over the Internet.
The paid survey process is fairly straightforward. You sign up with a paid survey site, and complete a member profile. Then, they send you an e-mail any time they have a survey that matches your profile
A paid survey is used to collect quantitative information about the participants' personal and economic habits set against their particular demographic. Incentivized surveys are considered to be more likely to catch a wider and more representative range of respondents compared to unincentivised surveys.
When a research company needs respondents from a demographic they cannot reach they can easily reach out to a worldwide or specialty panel. By offering a cash incentive to respondents in return for feedback these companies are able to quickly fill quotas and collect the information being sought by the client.
