Prolific is one of the leading survey sites because it has no disqualifications and has a high pay rate for time spent. All surveys sent to you are ones you have prequalified for by filling out some qualifier questions. Most surveys pay out $0.25-$5.00.
The only downside with Prolific is the frequency of surveys. You might only get 2-3 a week, but when you get a survey, they always pay well, are very fast and easy to do. Overall, Prolific is something you can hammer away at all day, but the survey experience is always great and so is the pay rate.
How do they pay? They pay via PayPal usually 1-10 days after you request it. You must have a verified PayPal to use them.
