Definition
Bounce rate is the percentage of visits to your site that end without meaningful engagement. Historically it meant single-page visits with no further interaction. In Google Analytics 4 the definition changed: bounce rate is now the inverse of engagement rate, so a bounce is a session that was not engaged.
That redefinition matters. In GA4, an engaged session is one that lasts longer than a set time, has a conversion, or includes two or more page views. Bounce rate is simply the share of sessions that met none of those, which is a more useful bar than the old single-page measure.
How bounce rate works in GA4
The relationship is direct:
Bounce rate = 100% − Engagement rate
If 60% of sessions are engaged, the bounce rate is 40%. Because it is now tied to engagement rather than page count, a shopper who reads a long product page and leaves is not necessarily a bounce, which is a more honest reflection of whether the visit had value.
There is no universal "good" bounce rate, because it depends on the page's job and the traffic's intent. A focused landing page and a blog post have very different expectations, so the useful benchmark is your own trend and the comparison between similar pages.
Why bounce rate matters for revenue
Bounce rate is a directional signal, not a decision on its own. A high bounce rate on a page that should engage, like a key product or category page, suggests a mismatch: the visitor did not find what they expected, the page loaded slowly, or the content did not hold them. Each of those is a fixable problem that costs revenue upstream of conversion.
But read it with care. Bounce rate does not measure revenue, and optimizing it directly can mislead. A change that makes people click more without buying more improves bounce rate while doing nothing for the business. That is why serious analysis treats bounce rate as a clue about engagement and pairs it with metrics that measure money, like conversion rate and revenue per visitor.
From a Revenue Intelligence perspective, a high bounce rate on a high-value page is a prompt to investigate, not a leak in itself. It points you toward a page worth examining, where the actual revenue leak, a weak product page or a slow load, can be found, priced and fixed. Our guides to product page optimization and GA4 funnels cover turning that signal into action.

Bounce rate is the inverse of engagement rate and a companion to conversion rate. It flags pages that fail to hold visitors, but only revenue metrics tell you whether fixing engagement actually earned more.
In short
Bounce rate is the share of unengaged visits, redefined in GA4 as the inverse of engagement rate. It is a directional signal about whether pages hold attention, useful as a clue but never optimized on its own, because engagement without revenue is not a win.
