Bounce rate
Measurement and data
Measurement and data
Bounce rate is the share of visits where someone leaves without further action. In GA4 it is exactly the inverse of the engaged-session rate.
In old Universal Analytics a bounce was any visit with exactly one pageview. In GA4 a session counts as engaged once someone stays over ten seconds, views a second page or converts; everything else bounces. So do not compare numbers across those systems.
A high rate is not automatically bad. On a blog or an opening-hours page someone may find exactly what they needed and leave happy. On a category page or a step in your enquiry flow it is a signal.
Look per page and per source rather than at the site average. Slow loading, a mismatched ad promise and a page that does not answer the query are the usual causes.
In practice
Lowering the rate artificially with extra events or scroll tracking. The number improves while behaviour does not.
