How do I start receiving surveys through Google Opinion Rewards?

To start receiving surveys through Google Opinion Rewards, one simply needs to download the Google Opinion Rewards app from either the Google Play Store for Android devices or the App Store for iOS devices. After installing the app, the user must then sign in with their Google account and complete a brief introductory survey that will assist in personalizing the surveys they receive. Post this initial setup, the app will send occasional surveys to the user based on their profile and location history. Every time a new survey is ready, a notification will appear on the device. By completing these surveys, users can earn Google Play credits (on Android) or PayPal funds (on iOS) which can be used for purchases on their respective platforms.
