See how it’s calculated, why GA4 changed it and how to find the cause on a page. ## What bounce rate is Bounce rate is the percentage of sessions that end without the visitor doing anything meaningful on the site. If 1,000 sessions start on a page and 400 of them bounce, the bounce rate is 40%. What counts as “meaningful” depends on the tool, so the same page can show different bounce rates in two analytics products. ## How tools define a bounce Two definitions are in common use, and mixing them up is the usual reason numbers disagree. - Universal Analytics counted any session with a single page view as a bounce, even if the visitor read the whole page for ten minutes. That definition is still used by many other tools. - Google Analytics 4 defines a bounce as a session that was not engaged: it lasted under 10 seconds, had no key event and viewed only one page. Bounce rate there is simply 100% minus engagement rate. A bounce rate from before GA4 and one from after it measure different things, so don’t compare them directly. Check the definition before you read a number. ## What counts as a good bounce rate There is no single good bounce rate, because it depends on what the page is for. A blog post that answers a question can have a high bounce rate and still do its job, since the reader found the answer and left. A pricing page or a checkout step with the same number is a problem, because those pages exist to move people forward. Compare like with like: the same page type, the same traffic source and the same device, over the same period. A landing page for a paid campaign should be judged against your other campaign pages, not against your blog. Issues in Journey Insights.

The cause is usually one of a few things, and each leaves a different trace. - The page loaded slowly, so the visitor left before it appeared. See Core Web Vitals and conversions. - The page didn’t match the promise of the ad, search result or link that brought them there. - The page was hard to use: a button that did nothing, a form that wouldn’t submit, a pop-up covering the content. These show up as rage clicks and dead clicks. - The visitor got what they came for. This is a healthy bounce and needs no fix. The number tells you that sessions ended early. It can’t tell you which of these happened, so you need a second source of evidence before you change the page. ## How to find the cause on a page Pick the page with a high bounce rate that sits closest to a conversion, then look at what visitors did on it before leaving. - Open a heatmap to see where clicks land and whether anything people tried to use got no response. A scroll map shows how far down they got before leaving. - Watch a few session recordings of bounced sessions, filtered to that page and to mobile and desktop separately. - Split the bounce rate by traffic source and device. A page that bounces only on mobile, or only from one campaign, points to a specific cause. Write down what you expect to find before you look. If three recordings in a row show the same stall, that is a finding. One odd session is not. ## How to confirm a fix lowered bounce rate Change the page, then measure the result instead of assuming it worked. A before-and-after comparison is quick but mixes in everything else that changed over the same weeks. An A/B test splits visitors between the old and new page at the same time, so the comparison is fair. Watch the conversion rate next to bounce rate. A change can lower bounces by pulling in people who then don’t buy, and a lower bounce rate is only a gain if the page still converts. ## Bounce rate in Cuttl In Web Experiments, bounce rate is one of the metrics you can pick for a test. Cuttl counts a bounce when the session in which a visitor first saw the test had a single page view, and the goal direction is set so that fewer bounces is better. Bots and AI agents we detect are left out of these numbers. In Journey Insights, Cuttl flags pages where visitors go straight back, called quick backs: sessions where the visitor goes back to the previous page within 8 seconds. The issue lists the affected sessions, so you can open their recordings and see what happened. ## Common questions ### What is a bounce rate? The percentage of sessions that end without meaningful engagement. In Universal Analytics that meant a single page view. In GA4 it means a session under 10 seconds with one page view and no key event. ### What is a good bounce rate? It depends on the page type. A page that answers one question can bounce often and still work, while a pricing or checkout page with the same rate needs attention. Compare similar pages, sources and devices. ### Is a high bounce rate bad? Not always. If visitors found what they needed and left, a high rate is fine. It is a problem when the page exists to move people to a next step and they leave instead. ### How is bounce rate different from exit rate? Bounce rate counts sessions that started on a page and ended there with no engagement. Exit rate counts how often a page was the last one viewed in a session, whatever the visitor did earlier. ### How do I reduce bounce rate? Find the cause first: check load speed, whether the page matches the promise that brought people in, and whether anything on it is broken. Heatmaps and recordings show which, then an A/B test confirms the fix. ### What is form analytics?
