Retention

Quick answer

Retention refers to the ability to keep or hold on to something, such as customers or users, over a certain period of time. In marketing, it's about the strategies and tactics businesses use to encourage customers to continue using their product or service, rather than switching to a competitor. In A/B testing, it helps teams explain which part of the visitor experience changed and why that change could affect conversion behavior.

Key takeaways

  • Retention describes a user experience factor that can influence attention, trust, or action.
  • It is useful for writing clearer hypotheses and choosing better experiment metrics.
  • The impact can vary by device, visitor intent, and where the user is in the journey.

Definition

Retention refers to the ability to keep or hold on to something, such as customers or users, over a certain period of time. In marketing, it's about the strategies and tactics businesses use to encourage customers to continue using their product or service, rather than switching to a competitor.

What Retention means in A/B testing

In conversion optimization, Retention describes a part of the visitor experience that can be observed, measured, and improved through testing. It is often used when forming hypotheses about why users click, scroll, buy, sign up, or leave.

Why Retention matters

Retention matters because small changes in user experience can have a measurable impact on attention, trust, and conversion behavior. It gives experiment teams a clearer way to describe what they are testing and why it may affect results.

Example of Retention

For example, a marketer may test a different hero message, call-to-action, or page layout. Retention helps explain which part of the user journey changed and why that change could affect conversion behavior.

How to use Retention

Use Retention while forming a hypothesis. Identify the user behavior you expect to change, choose a metric that can capture it, and test one clear improvement instead of changing many page elements at once.

Common mistake

A common mistake is assuming Retention affects every visitor the same way. Segmenting by device, traffic source, and intent can reveal whether the improvement helps the audience you actually care about.
