You can expect to earn $2-$5 for most of the surveys in general. For some special surveys you can earn up to $50 per survey but those are rare. Harris Poll also conducts paid focus group studies where you can earn $50-$100 per study. Usually these focus group studies are 1-2 hours long where you interact with other participants under a supervision of a focus group moderator.
First, thank you for providing this extensive list. I wanted to offer a quick follow up. After reading your post I decided to give Survey Junkie a try and I’ve already closed the account. Yes, I can tell it’s well organized and it is definitely a user-friendly platform. The problems I experienced were first that not one of the surveys they emailed me about were available. I did, however, complete several surveys from the site itself and I found them to be lengthy – in itself, not a problem but 3 out of 5 told me I didn’t qualify after I’d already invested 10 – 12 minutes filling out the forms. They got more than enough information from me to be useful which is an old and highly unethical trick in market research – which happens to be my background. All in all a LOT of wasted time.
Instagc is by far my favorite site. There are tons of surveys, email sign ups, free sample offers, videos, etc. Once you earned enough (usually about $5) you can redeem for gift cards INSTANTLY. They also have pay pal and direct deposit. As a stay at home mom with a tight income, Instagc has been a godsend. It’s free to join, of course.

Survey Club has been offering online paid surveys since 2005, and in the fast paced every changing world of the web that’s a reassuringly long amount of time. They are a bit of an acquired taste, in that they specialise in long, detailed surveys for high end clients rather than the quick and cheerful consumer surveys that you may be more familiar with. Whilst this does mean that you may have to commit a bit more time, it does mean that if you have the patience to persevere with them they pay more money than most survey and reward sites. They also offer local taste tests (see what I said about ‘an acquired taste’?), and secret shopper opportunities.
