Scour

Scour is similar to Swagbucks, in which you are paid to search. You aren't necessarily paid for every search but you earn points and later on, are able to redeem them.
You can earn points by searching, commenting, and voting for sites. Once you get 6500 points, you can redeem a $25 VISA giftcard.
It seems like a lot of work but if you use it as if you were using Google, Yahoo!, etc, you'll be making points quick enough.

What makes it better is that when you get referrals, you get 25% of your referral's points.

Community Guidelines are as follows:

Max amount of points per search = 3.. Points will be earned from the first 100 daily searches with a daily cap of 300 total points. Our current rewards schedule for Canada, France, Germany, Italy, Netherlands, Poland, Spain, U.S., and U.K:
