How does Google Opinion Rewards work?

Google Opinion Rewards is an app-based program created by Google that incentivizes users to participate in surveys and share their opinions. Once a user downloads the app and sets it up on their smartphone, Google will occasionally send them short surveys based on their interests and recent activities, such as visiting a store or using a Google product. In exchange for completing these surveys, users are rewarded with credits that can be used towards purchases on the Google Play Store or, in some countries, transferred directly as cash to their PayPal account. The amount of credit earned per survey varies but is typically a modest sum acknowledging the user's time investment, and the frequency of surveys also depends on the user's profile and the demand from survey creators.
