What metrics would you define for the success of Facebook Lite?

Focus on identifying key performance indicators that align with the unique goals of Facebook Lite, which is designed for users in areas with limited connectivity and lower-end devices. Consider metrics that reflect user engagement, such as daily active users (DAU) and session length, as well as retention rates over time. Additionally, think about the impact of Facebook Lite on data usage and load times, as these are critical for its target audience. Discuss how you would balance growth metrics with user satisfaction metrics, ensuring that the product remains effective and valuable for its users.
