Which term is used for improvements in user retention due to better overall experience?

The term used for improvements in user retention due to a better overall experience is User Experience (UX). User Experience encompasses all aspects of the end-user's interaction with a company, its services, and its products. When the design, functionality, and accessibility of a product or service are enhanced, users are more likely to have a positive experience, which can lead to increased retention rates. A good UX not only addresses the user's needs and pain points but also creates a sense of ease and satisfaction that encourages them to return.

While User Satisfaction relates to how content a user is with a product or service at a specific moment, it does not necessarily imply a long-term commitment or retention. Customer Loyalty is more focused on the emotional connection a user feels towards a brand, which can stem from a positive UX, but is not solely defined by it. User Engagement refers to the level of interaction and involvement that users have with a product, which can be a result of a good UX, but it doesn't specifically address the aspect of retention improvements directly tied to the overall experience a user has with a brand or service. Therefore, User Experience (UX) is the most relevant term in this context.
