What is Bounce rate?
Bounce rate is the percentage of visits that ended after a single interaction — one page, no second action. It is often read as a quality score, which it is not. A reference page that answers the question completely will have a very high bounce rate, and that is the page working exactly as intended.
What counts as a bounce
Classically: a visit with exactly one pageview and no further tracked interaction. Tools differ on what counts as “further” — a scroll, a click on an outbound link, a custom event, or a second page.
This matters more than it sounds. GA4 replaced bounce rate with engagement rate and defined engagement as a visit lasting over ten seconds, firing a conversion, or seeing two pages. A visit that would bounce under the classic definition may be engaged under that one. Two tools reporting “bounce rate” on the same site can be measuring different things.
The misreading
Bounce rate is treated as a proxy for content quality. It is closer to a proxy for whether the page needed a second page.
- A glossary entry that defines the term, is read, and is closed: bounce, and a success.
- A support article that solves the problem: bounce, and a success.
- A pricing page a visitor leaves in three seconds: bounce, and a real problem.
The metric cannot distinguish these. Only intent can, and intent comes from knowing what the page was for.
Reading it usefully
- Compare like with like. Bounce rate by landing page and by traffic source is informative. A site-wide average across a blog, a pricing page and a docs section describes nothing that exists.
- Watch the trend, not the level. A jump on one page after a change is a signal. A 68% site average is not a grade.
- Pair it with visit duration. A bounce after four minutes means the page was read. A bounce after four seconds means it was not.
- High bounce plus high conversion is fine. Some pages convert on the first screen, and there is nothing to fix.
