What is Google Opinion Rewards and how does it work?

Google Opinion Rewards is a reward-based program developed by Google. It operates as a market research tool that allows users to earn credits by completing surveys and sharing their opinions on various topics, products, and services. To get started, users download the free app onto their smartphone and set up an account. From then on, they receive occasional notifications when a survey is ready for them. Typically, these surveys are quite short, consisting of a few questions that can be answered in a minute or two. Once a user completes a survey, they are rewarded with Google Play credits or PayPal funds, depending on their country and the platform they're using. These credits can be redeemed for purchasing apps, games, books, or other digital goods offered via Google Play Store.
