Bounce Rate
Metrics & MeasurementDefinition
Bounce rate is the percentage of sessions in which a visitor does not engage with your page, then leaves. In GA4 a bounce is simply a session that was not engaged, meaning it lasted under 10 seconds, had no conversion and no second pageview. It is the inverse of engagement rate.
Bounce rate used to mean a single-page session in Universal Analytics, full stop. Someone landed, read the whole page, found their answer and left, and that counted as a bounce even though the visit was a success. GA4 fixed this confusing definition by tying bounce to engagement instead. A session now bounces only if it was not engaged: under 10 seconds long, no conversion event and no second screen or page view. That makes the metric far more useful, but it also means a GA4 bounce rate is not comparable to an old Universal Analytics one.
Because bounce rate is just 100 percent minus engagement rate in GA4, it is a quick signal rather than a diagnosis. A high bounce rate can be a problem (mismatched ad-to-page message, slow load, wrong audience) or perfectly fine (a blog post that answered the question in 8 seconds, a contact page someone scanned for a phone number). The number only becomes meaningful when you split it by landing page, traffic source and device, then ask whether each segment's behaviour matches its intent.
GA4 calculates bounce rate as the share of sessions that were not engaged. A session is engaged if it lasts longer than 10 seconds, fires a conversion, or has at least two page or screen views. Anything that meets none of those is a bounce. You can lower bounce rate by improving page speed, matching ad copy to landing page content, surfacing the answer above the fold, and adding clear next steps, but only when a high rate actually signals a problem for that page.
Bounce rate matters most as a relative diagnostic for paid traffic, where every bounce is money spent on a click that went nowhere. If a campaign sends visitors to a page they immediately abandon, you are paying for clicks that never had a chance to convert. Watching bounce rate by landing page and source helps you spot ad-to-page mismatches, broken mobile experiences and irrelevant targeting fast. It is a leading indicator: bounces today often explain low conversions tomorrow.
Formula
Bounce Rate = 100% - Engagement Rate (in GA4) Example
A landing page gets 1,000 sessions from a Google Ads campaign. 350 of them were engaged (over 10 seconds, a conversion, or a second pageview), so engagement rate is 35 percent and bounce rate is 65 percent. For a paid landing page that is high, and worth investigating: check whether the ad promise matches the headline and whether the page loads fast on mobile.
A blog article gets 1,000 sessions with a 55 percent bounce rate. That is normal for informational content where many readers get their answer and leave. Here a high bounce rate is not a red flag; the better question is whether engaged readers move on to a relevant offer.

Frequently Asked Questions
-
There is no universal benchmark, because GA4 ties bounce to engagement. Informational blog pages can sit at 50 to 70 percent and be fine, while a paid landing page above 60 percent usually warrants a look. Always judge it relative to the page's intent and traffic source rather than against a single number.
-
Universal Analytics counted any single-page session as a bounce, even a successful one. GA4 defines a bounce as a session that was not engaged, meaning under 10 seconds, no conversion and no second pageview. A visitor who reads one page for 30 seconds is engaged in GA4 but counted as a bounce in the old model.
-
Match your ad message to the landing page, improve load speed (especially on mobile), put the answer or value proposition above the fold, and give a clear next step. But only optimise when a high bounce rate actually signals a problem for that page type, not on pages where leaving quickly is normal.
