Online surveys generally do not pay that well. Some pay more than others and you get surveys depending on your personal circumstances. Not all pay cash, some pay gift cards etc... but since I am at home anyway and most do not take that long I do them. These are the ones I use and trust. There are a lot of dodgy companies out there, so I only deal with reputable ones.
1.) RewardsCentral is a daily one. I log on every day, do a quick survey, which is one click, plus a web click, and any bonus webclicks. You can also earn money shopping through them, you get sent reward mail and they have a sister company
MyOpinions. They have more surveys plus an instant win game you can play each week to get bonus points. Once you have 100 points, you can trasnfer them to your RewardsCentral account. 3300 points is $33. But you get charged $3 from that $33 to cash the cheque. You can get gift cards instead though.
2.) Pureprofile pays you to do surveys and visit sites. It varies, you just need to log on every day. Sometimes it's a website visit for 10c, sometimes it's a survey for $5. The most I had was a $12 survey. Once you reach $25 you can "cash out" and it gets deposited in your bank account. Too easy.
3.) Yourvoice is great for movie tickets and gift cards, but you don't earn cold hard cash from them. Still, it means you don't need to spend your own money to go out.
These are the main ones I use. If I come across anymore, I'll let you know.
