With Google eager to learn all it can about its users it has launched a new scheme named Screenwise. Users are rewarded every 3 months with a $5 Amazon gift card (up to a maximum of $25). In return you must install a browser add-on which will send reports back to Google with what you’re doing online, including the sites you visit and how you interact with them.
Naturally there are a few terms and conditions. For starters you obviously have to have a Google account, you must be 13 or older and finally you have to use Google’s Chrome browser. If you’re happy to sell your privacy to Google (for a very low amount!) you can sign up here.
