No matter the site, the earnings from taking surveys can be meager compared with other work opportunities. The federal minimum wage is $7.25 per hour, for example, and our hourly earnings ranged from 41 cents to $2.03. Most survey sites also required a minimum amount of points before we could redeem them for rewards. On many of the sites, we didn’t reach that minimum amount after five hours of work.
To save time and money, many companies are turning to online market research. Surveys, in particular, can easily be conducted online or over e-mail. The cost of a 200-person, e-mail survey is $2,500 to $5,000. To get the same number of responses from a snail mail survey would cost between $5,000 and $7,000, and phone surveys can run as high as $15,000 [source; Yahoo! Small Business].
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. 
There are also many questionable "middleman" third-party paid survey sites that hype easy money for participating in online marketing research from home. Here, the old adage is true: if it sounds too good to be true, it usually is. Further, it’s worth knowing that there’s a lot of competition among these companies for your participation – which means potential for exaggeration, at the very least, if not outright scams.
Joining isn’t as straightforward as merely signing up, because you need an invite. However it’s not as tough as it sounds, as there are plenty of links doing the rounds online if you look hard enough, and Pinecone also advertises on websites, so you might get lucky by keeping an eye on banner adverts. Once you’ve signed up, you’ll be vetted to see if you qualify – based on whatever demographics their clients want at that point – and if so, the fun begins!
They are new to me. I did a search and wasn’t able to turn up much online, other than this – Someone thinks they are more of a “survey router,” not the same as answering Q’s directly for a survey panel. So I think I personally wouldn’t sign up, but as always I recommend that you do you your own research in addition to the research I’ve done.
Ultimately, it is very unlikely that participating in online surveys will provide you with a steady, livable wage. However, if you enjoy participating in online surveys (especially if you like the prizes, coupons, and other more typical non-monetary earnings), be sure to avoid questionable third-party sites. Look for real paid surveys online that don’t require you to invest money.
Illegitimate companies and scammers have a simple objective. They're after your information in order to get your money. It's much more common for internet scammers to target hundreds of people for small sums rather than a single person for thousands. This is because demanding large sums for a product that is somewhat unclear is an obvious red flag to most.

Mainly conducting polls for governments, public bodies and the business world, Opinion Outpost is a popular survey site as unlike some sites, which require you to accrue a significant amount before you can claim your money, it has one of the lowest payout thresholds. You only need to fill out five surveys, earning a couple of dollars, before being able to claim pay, so you can redeem your money more quickly.

Toluna. Unlike many other sites, Toluna lets users pick the topics of their surveys, such as electronics or travel, which made the work more interesting. However, this perk didn’t make up for its low pay. Upon converting points to cash, we earned only 71 cents per hour — one of the lowest rates of all the sites we tested. Our five hours’ worth of points weren’t nearly enough to redeem the cheapest gift cards. Learn more in our Toluna review.

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.
