Google Opinion Rewards is a program developed by Google that allows users to earn rewards by participating in short surveys. These surveys cover a range of topics, including opinion polls, hotel reviews, and merchant satisfaction. Users are notified when a survey is available and receive compensation in the form of Google Play credits or PayPal payments upon completion.

To sign up and earn rewards with Google Opinion Rewards, users must be at least 18 years old and reside in one of the 39 countries where the app is available. The app is compatible with Android devices running version 2.3.3 and up, as well as iOS devices. Users need a Google account to register and, for PayPal payments, must link their PayPal account to receive funds.
