Bounce rate

Bounce rate shows what share of your visitors leave without really doing anything on your website. For a long time, the simple definition applied: someone views one page and disappears. In Google Analytics 4, that has changed. There, bounce rate is the inverse of the engagement rate: a session counts as a "bounce" when it wasn't engaged, meaning it lasted less than ten seconds, contained no conversion event and had only one pageview.

That difference matters when you compare old reports with new ones. A drop or rise may simply be the result of a different measurement method. So the old bounce rate from Universal Analytics and the new one from GA4 can't simply be compared side by side.

Is a high bounce rate bad?

Not automatically. It all depends on what the visitor came for. Someone looking for the phone number of a plumber in Leeds who opens the page, sees the number and calls has found exactly what they needed. Yet that visit may still be recorded as a bounce, especially if the call isn't measured as an event.

A high rate is mainly a signal to dig deeper when you do expect people to click through from a page, such as a product overview, a quote form or a landing page for a campaign.

Possible causes of lots of bounces

• The page doesn't match the search intent. Someone is looking for prices and gets a general company introduction.
• The page loads slowly, especially on a smartphone with a weak connection.
• There's no clear next step: no button, no link, no way to get in touch.
• The title or description in the search results promises something different from what's on the page.
• Annoying elements, such as pop-ups that cover the screen straight away.

How to work with it

1. Look at bounce rate per page and per traffic source, not just the average for your whole site.
2. Compare pages with a similar purpose with each other.
3. Measure important actions as events: clicks on a phone number, a download, a completed form.
4. Look at page speed and how the page displays on mobile.
5. Test changes step by step and compare the results over a sufficiently long period.

An online children's clothing store in Manchester, for example, saw that visitors from a social media campaign were dropping off en masse on the homepage. By sending them straight to the right product category, the first screen matches their expectations better. In a case like that, bounce rate isn't a goal in itself, but a pointer to where to start looking.

Bounce rate and visitors from AI search

Visitors who reach your site via ChatGPT, Perplexity or Google AI Overviews have often already received part of their answer. They click through to check something specific or to get in touch. That can lead to short visits that are still valuable. So don't stare blindly at bounce rate, but combine it with conversions and other engagement metrics. In the Spacebird Cockpit, you see these figures together, so you can understand more quickly which pages really need attention.
