Exit Rate

Definition

The exit rate is the percentage of visitors who leave your website from a specific page. This metric is used to identify which pages are the final destination before a visitor leaves, indicating possible issues with those pages. It's calculated by dividing the total number of exits from a page by the total number of visits to that page.

What Exit Rate means in A/B testing

In conversion optimization, Exit Rate 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 Exit Rate matters

Exit Rate 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 Exit Rate

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

How to use Exit Rate

Use Exit Rate 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 Exit Rate 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.
