It's a good idea to create an email address just for answering surveys. I am signed up with multiple companies, but I only answer about a survey per day, depending on my schedule. Like I said, the more you do, the more you'll earn, but the amounts are small...except when they add up. :)
Each day, check your survey email to see what surveys are available. You'll want to do this quickly, as the number of many surveys are limited.
Here's a list of some survey companies available:
- Swagbucks - you'll be "paid" in Swagbucks, which you can use to get gift cards or other merchandise.
- Synovate-one of my favorites...I've gotten the chance to try products before they hit the market!
- Mindfield-
- Opinion Outpost-the first company I started with, and continues to be my favorite!
- Survey Spot-I get an email every other day or so, and although I have yet to cash out, this company has been very easy to work with.
