What is Bounce Rate?
Bounce rate is the percentage of sessions in which a user lands on a page and leaves without triggering any additional interaction or pageview. In GA4, bounce rate is the inverse of engagement rate: a session is considered a bounce if it lasts fewer than 10 seconds, has no conversion events, and includes only a single pageview.
Why it matters
A high bounce rate can signal poor content relevance, slow page speed, or a mismatch between what users expect from the search result and what the page delivers.
