Surveys for Cash

An effective way to increase your earnings through some survey websites is to refer a friend or add a link to your site and you will receive points or cash in return. Below are a few sites that will reward you for your referral:-

• Rewardcentral you will receive 200 points when your friend has earned 400 points
• Pureprofile will give you $1 for every $5 your friend earns. you will recieve up to a max of $5

As I find more referral links I will add to this list.
