Not counting the profile survey, I attempted 38 surveys and qualified for seven of them. That’s an 18% success rate, which is on the low end among the 12 sites we tested. Most of the time, I’d immediately receive a disqualification notice with a link to a new survey opportunity. For a few surveys, I answered questions for a couple minutes before getting the boot.
The survey sites online fall into three broad categories: (i) those that are outright scam sites that will only waste your time and not pay you after taking the surveys (ii) those that will pay only paltry amounts that do not justify the time spent on the surveys (iii) those with which you can earn decent additional income and get paid instantly through Paypal.
