Survey Junkie makes it quick and easy to jump into the survey game. According to their websites, they say they are the most popular spot online to earn cash and rewards for sharing your thoughts, while that might not be technically true, they are one of the largest survey sites out there. They were launched all the way back in 2005 (which is pretty old for a survey site) and they have over 4,000,000 members.
Mainly conducting polls for governments, public bodies and the business world, Opinion Outpost is a popular survey site as unlike some sites, which require you to accrue a significant amount before you can claim your money, it has one of the lowest payout thresholds. You only need to fill out five surveys, earning a couple of dollars, before being able to claim pay, so you can redeem your money more quickly.
