There are companies that would have you believe that you can make $75 for one survey, but I've never seen this ever online. The major problem with survey sites is the lack of surveys that you are qualified to take or the fact a company will invite you to surveys and then disqualify you. Many survey sites are online and have apps that you can install on your mobile device. However, they basically post the same surveys on several different sites at once. Therefore, if you took the survey on one site, qualified, and were paid for the survey, you can't take it again and be paid. Most people are lucky to receive 1 or 2 surveys a week that they are paid for. Normally they will earn $0.05 to $0.20 per survey. Today, many survey sites have had to add other means of making money from the site. They have offer walls where you can sign up for offers, click on ads, watch videos or download apps to earn a few cents for your work. I have never met a person who could live or make a living on surveys alone. In the past, this was a bit more reasonable than it is today.
