The only problem with rewarding consumers for taking online surveys is that it gives them the incentive to cheat. The more surveys you fill out, the more points you get. So people get creative: They randomly answer survey questions as quickly as possible, establish multiple e-mail addresses to answer the same survey five or six times, or lie about their demographic (a white male says he's a black female, for example) to participate in surveys for which they otherwise wouldn't qualify [source: Frost & Sullivan].
Cashback shopping: Who doesn’t love getting cash back? It's a great incentive for shopping because it feels like you're being paid to do so. It's usually best to use the offers only when you were already intending to buy the product. If you love saving money at discount stores or at places that offer cash back, there are a lot of survey sites out there that will open a lot more offers to you. Survey sites can offer cash back because they're paid a portion of the profit for referring you.
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.
Product testing can be a fun way to make some extra money and also get a chance to try something new before the general public. This should be treated as a bonus though, as you have no control over whether you’ll be chosen, as it is down to whether the company thinks you are the correct audience. The firm also runs lucky draws throughout the year, where you can win between $500 and $5,000, and you are entered into them as a reward each time you fill out a survey.
There have been some reports of technical glitches on the site preventing users from receiving their earnings, but customers services are contactable and said to clear up most issues for workers. Valued Opinions has a unique “badge” program, allowing its most active members to work up five levels of achievement from bronze through silver, gold and platinum to the top tier of diamond, by carrying out extra mini tasks.
To take surveys, you need to qualify. This means answering a battery of questions up front—before the paid portion of the survey. Page attempted a variety of side hustles to pay off her debt, and says that taking online surveys was the “least helpful” side hustle she tried, mostly because she simply couldn’t even get to the surveys themselves. “You can spend almost 10 minutes just trying to qualify for a survey, and then [get] declined,” she says. “It takes way too long to determine if you’re eligible to take the survey, just to make $5,” she says. Short of magically being the right demographic for every survey, you’re looking at getting turned away more often than not, and wasting time answering questions that don’t come with a pay off.
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].

About that money: Survey companies typically don’t pay you for each and every survey—you have to meet a payout amount to earn your reward. Page says it took her months to reach the $30 payout on one survey site—time she could have easily spent on more lucrative side hustles. This presents a problem if you need money fast or if you decide to change course and try something else—you might end up answering tons of questions and never actually see that money.
I don’t see PaidViewpoint on your list. I like using that site. I signed up for it on June 28, 2016, but I guess I forgot about the site and stopped using it on July 24, 2016 but had a total of $1.91. I started using it again on May 5, 2018, and I’m now up to $27.05 and have a trait score of 10, which is the highest. The surveys are easy and you don’t get disqualified. I mostly earn 10 cents, but once in awhile I earn some good money like 62 cents. It does take awhile to add up, but it’s free money.
While surveys vary widely in how they are conducted and used, there are a number of components that are common across nearly all surveys. Many of these common features have been studied in extensive detail by survey methodologists, psychologists, statisticians, and many other fields of research. The general process of survey research is outlined in the figure below.
