The point of each survey is to present you with a topic you're interested in and qualified to discuss for the benefit of the researcher. Surveys range in time required, from very short to quite long. Because researchers are looking for opinions only from certain segments of people, you may find you have to try a few surveys before you're qualified to give your opinion on one. Keep at it, and you'll eventually find one that's right up your alley.
Scammers use a diverse variety of methods to allure and dupe unsuspecting victims. Some ads and offers look so real that even the most seasoned internet veterans can be tricked. However, many scams target people new to the market who may be more susceptible to “get rich quick” schemes because they're unaware of what you can reasonably make taking surveys. It is incredibly uncommon to be offered more than $10 to complete a 20 minute survey. Not that one offering that or more is definitely a scam, it's just important to be cautious. While some experienced and well credited survey takers receive legitimate offers paying that pay big money, if you're new to survey taking you should definitely steer clear of anyone offering you hundreds to complete a survey.
It’s easy to earn cash for surveys. How much you get paid completely depends on how many paid surveys you attempt and complete. Each online survey has a different payout, with some offering as much as $50. Most will pay less, but also take less time. Expect to earn about 40 to 200 SB points per survey (100 SB = $1), with occasional opportunities with much higher earning potential.
