Retention Loop

A Retention Loop is a strategy or product feature that brings users back repeatedly. Unlike one-off marketing (like a single email), a loop is self-reinforcing. For example, a social network uses notifications to bring you back, where you create more content, which triggers more notifications for others. Sustainable growth depends more on retention loops than acquisition—if you can’t keep users, no amount of new traffic will save the business from 'leaky bucket' syndrome.
