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 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.
