Nielsen Computer and Mobile Panel offers an easy way to earn rewards by sharing your device usage data. By downloading their app on your smartphone, tablet, or computer, Nielsen collects anonymous data on your internet usage patterns to help companies improve their products and services. In return, users earn points that can be redeemed for gift cards and other rewards. Participation is passive, meaning you don’t have to actively engage with the app; simply keep it installed and running in the background. Nielsen also offers regular sweepstakes entries for additional chances to win cash prizes.
