They include sites that seem to be their competitors because they earn referral fees when you buy memberships. A couple mentioned in scam forums even try to dupe you into buying the same list at other membership sites they own under different names. Naturally, these sites also have an incentive to exaggerate how much you'll earn from online paid surveys.
It’s never a good idea to write false information on your paid survey account or sign up for paid surveys that don’t match your characteristics. For example, if a paid survey is looking for a NASA aerospace engineer who is also a competitive food eater and has won the tour de France twice it isn’t a smart idea to claim to match those parameter (unless you really do). Paid survey companies often share information and if you have taken paid surveys for another company under the pretenses that you are a newly graduated software developer in Brighton, chances are that they will notice the discrepancies and you might be penalised for it. There have been a few cases of people having their paid survey account banned and all their hard earned money revoked for providing false information on a paid survey. It’s also not a good idea to register two email accounts for taking paid surveys because many paid survey panels frown upon this sort of behavior and may even ban you from taking their paid surveys.
Opinion Outpost is one I have been doing for the last 7 years (SEVEN! I had to look back through to see how long it was) I have made 260 dollars in that time (roughly 37 dollars a year). I like them because I seem to qualify for a lot of them, (I think I have made a lot of that money this last year) you can cash out at every ten dollars (into your paypal account) the pitfalls they send quite a few emails between 1-5 a day and if you don’t qualify you only get a sweeps entry and in 7 years I have never won anything. it just seems so easy to cash out .
We've tested hundreds of sites where you can take paid surveys for money and we've found that Swagbucks by far is our #1 pick. They've been around for years and have a solid track record of paying their users. Plus, we also like that they offer opportunities to get paid for doing things other than surveys, like signing up for offers or shopping in their portal.
A well known survey panel, Valued Opinions is owned by leading market research company ResearchNow and is open to people in more than 20 countries around the world, including the USA, UK and Australia. The site uses a range of different languages and has around three million members busily filling in surveys and questionnaires. Most surveys taken will reward you between $1 and $5 and take up to around 20 minutes to complete, asking you about marketing, brands and products and even news events. There is a steady rate of invites to surveys, but you won’t always be qualified for them, which can become tiresome.
