Push Notifications
Push notifications are messages sent from a server to a user's device (e.g., smartphone, desktop, or web browser) to deliver timely information, alerts, or updates without requiring the user to actively open an app or website. They are commonly used for real-time communication, such as news alerts, social media interactions, or transactional updates, and rely on platform-specific services (e.g., Apple Push Notification service, Firebase Cloud Messaging) to handle delivery. This technology enhances user engagement by keeping apps relevant and providing immediate feedback.
Developers should learn and use push notifications to improve user retention and engagement in mobile and web applications, particularly for time-sensitive scenarios like messaging apps, e-commerce order updates, or breaking news alerts. It's essential for applications that require real-time communication, such as social media platforms, productivity tools, or IoT devices, to keep users informed and drive re-engagement without constant app usage. Implementing push notifications can significantly boost app metrics like daily active users and conversion rates by delivering personalized content directly to users.
