Definition of Bounce Rate:
- In GA4, the bounce rate is the percentage of sessions that were not considered engaged.
- A session is considered a bounce if any of the following criteria apply:
- The session lasted less than 10 seconds.
- No conversion events occurred during the session.
- There were fewer than 2 pageviews or screenviews1.
Calculation of Bounce Rate:
- To calculate the bounce rate, follow this formula:
- GA4 Bounce Rate=Total SessionsBounced Sessions (non-engaged sessions)×100
Example:
- Imagine a user visits your website, spends less than 10 seconds reading content on a single page, and then leaves without triggering any events or visiting other pages.
- Since this session doesn’t meet the criteria for an engaged session (duration < 10 seconds, no key events, and fewer than 2 pageviews or screenviews), it would be considered a bounce.
- If this were the only session on your website, the engagement rate would be 0%, and the bounce rate would be 100%
