Bounce Rate

Bounce Rate is an analytics metric describing visits in which a user arrived on a page and left without a further tracked interaction. It has always been a measurement defined by analytics tools, not a signal that Google uses to rank pages, and its exact meaning has changed between analytics versions.

In the older Universal Analytics, a bounce was a single-page session with no additional interaction hit, and bounce rate was the share of such sessions. A high figure was often read as poor engagement, though it could simply mean a visitor found their answer on one page and left satisfied, which is a perfectly good outcome for a reference article.

GA4 redefined the idea. It first measures engagement rate, the percentage of engaged sessions, where an engaged session lasts longer than ten seconds, fires a conversion, or includes at least two page views. Bounce rate in GA4 is simply the inverse: the percentage of sessions that were not engaged. So a 70 percent engagement rate equals a 30 percent bounce rate. This makes the GA4 number more meaningful than its predecessor, but also not directly comparable to old Universal Analytics figures.

A frequent myth is that bounce rate is a Google ranking factor. It is not. Google does not receive your analytics bounce rate, and it has repeatedly said it does not use it for ranking. What Google can observe is behaviour in its own results, such as pogosticking, where searchers click a result then quickly return to choose another. That is a search-behaviour pattern, separate from the bounce rate inside your analytics account.
