Keep in mind, in order for you to be qualified for a survey, you must be in the right candidate for that survey, that is why it is very important to take those four surveys in the beginning (qualifications, general, household, interest) – read more about these surveys here and how to qualify for future surveys.
Velasquez says our information could be used for questionable studies or sold to health insurers, for example. Or it could be stolen, which is a risk with any website that stores personal data. Most of the information we gave away seemed harmless — our shopping habits and travel plans, for example. But information like your birthdate could be used with other stolen data to take your identity. So keep that in mind as you’re answering questions.
Return on Time – Is it an hour of your life for $2.00 or truly a fifteen minute survey?  We find out if the Return on Time (similar to Return on Investment) pans out.  Surely, some will be better than others for not wasting yours.

The site will even allow you to monetise your internet searches, if you swap from Google or Safari to their own search engine. The Swagbucks search engine, which is actually running Yahoo, will pay you Swagbucks every time you search. For games, there are options like Scrabble and Wheel of Fortune, which won’t pay you much, but could be worth a go if you fancied playing a game anyway! Swagbucks TV allows you to watch advertising videos on a range of topics, including news, fitness and entertainment. There’s a snag – your earnings are capped at 150 Swagbucks, but it is worth a look if you’re prone to wasting time watching viral clips.
Although it might seemed biased to put forth this assertion, the proof is truly in the pudding. Whereas virtually every other way you can earn money online will require some level of skill, more time or the like, paid online surveys consistently offer consumers an opportunity for completely autonomous and consistent participation. This means that there are no contracts, fillers or complexities to navigate, just simple, unadulterated activities that put extra cash in your pockets. 
Swagbucks. This site offers a lot of opportunities for surveys, but disqualifications are frequent. Sometimes we got disqualified just from clicking on a link to a survey. Swagbucks aggregates third-party surveys, so some sites it sends you to are better than others. It takes a long time to earn points, but the site’s expansive rewards marketplace has hundreds of options to choose from, including gift cards, sweepstakes and PayPal payments.

Surveys can be super quick and take just a few minutes to fill out, or require around 15 minutes of your time. Five minute surveys pay $0.50 and surveys range from $0.40 up to the higher – and rarer – ones at $10.Paying out by the usual methods, Crowdology does PayPal and also vouchers. Most importantly, the minimum reward threshold is low so when you’ve earned $8, you can cash it out, unlike other sites which make you wait until you have earned much more money.

Like American Consumer Opinion, Harris Poll Online offers cash incentives to people who are willing to log in regularly and complete online surveys and questionnaires. Once you join, you’ll begin earning rewards for each survey you take. Once you earn enough reward “points”, you can turn them in for purchases made on websites like Amazon, iTunes, Home Depot and Walmart. Conversely, you can also turn in your points for movies, books, and home goods ordered straight from the Harris Poll website. Plus, you’ll be entered into a $10,000 sweepstakes each time you complete a survey.

Design and pre-test questionnaires: Designing the questionnaire carefully and then pre-testing it before fielding it to your entire sample is crucial to getting data that are valid and reliable. For example, careful questionnaire design and pre-testing can help reduce the chance that respondents may interpret the meaning of questions differently. Future posts in this series will tackle these important steps in much greater detail.
