Prolfic is unlike any other survey site. You can easily earn £8 per hour you use this service. Prolific is designed to collect data for research studies usually hosted by Universities across the world. The researches pay you (and prolific) to answer questions that they can use in their research studies. With prolific you don't get disqualified from surveys. The preselect you using data you have given them. This gaurantees there will be no time you are working where you wont recieve compensation. I have personally earned over £200 with prolific. Prolific allows you to withdraw cash using Paypal. The minimum withdrawal amount is £5 and this can be attained very easily. The only real disadvantige to prolific can be the lack of surverys. Sometimes you might go a couple of hours without recieving a survey. Furthermore, surveys work on a first come first surved basis, so it is really easy to miss out.
YouGov is another survery site where you will be paid honestly for the time you spend completing surveys. You usually recieve at least one survey a day that takes roughly 8 mins a gives you 50 points (equivalent to 50p). You very rarely get disqualified and the surveys are often of political nature. YouGov lets you cash out once you have earned 5000 points (equivalent to £50) by bank transfer. I have only managed to complete this once as it can take about a month or two. I would recommend YouGov for the same reasons as Prolific. Consistency and an reasonable compensation.
Amazon MTurk allows you to complete small tasks requested by other uses in exchange for a small payment. Tasks are often small in nature, such as labelling whats on an image or transcribing a small amount of text. Usually, there is a bulk of similar tasks requested by the same user. Amazon MTurk requires you to withdraw cash to a US bank account, however you can use a third-party such as Hyperwallet (this is the method suggested by them). I would recommend MTurk to anybody who prefers completing tasks to mindlessly responding to surverys. It can be rewarding once you can developed and consistent work flow.
