The easiest answer to that question is to use some common sense. If it sounds too good to be true, it probably is a scam at worst or terribly over exaggerated at best.
Here are some of the things can help you weed out the paid surveys scam websites.
Read the testimonials – if they all talk about making tons of money and quitting their full time job, they are probably a scam. Better to be safe than sorry.
See if they have an earnings disclaimer – this document protects a legitimate company from being sued for false advertising. Scam companies don’t care if they get sued.
Guaranteed incomes amounts – they are all bogus. Since you control when and how much you work, no one can guarantee that you will earn a specific amount.
Check their privacy policy – make certain that they will not sell your information to anyone and that includes “partners” and “associates”.
Check the contact information – avoid websites that only list an email or PO Box number. They are making it very difficult for you to contact them.
Send a test support message – if they don’t respond in a timely manner or answer your questions to your satisfaction they may be a paid survey scam website.
Do a whois search on the domain name and see if they have been with the same registrar and web host for a while. Scam websites frequently change their domain names and web hosts.
Check with the online Better Business Bureau to see if there have been any complaints.
Check with Scam.com and RipOffReport.com for complaints.
