Bounce Rate
AnalyticsAlso: Single-Page Session Rate
Quick definition
Bounce rate is the percentage of sessions where a visitor lands on a page and leaves without visiting any other page on the site. Calculated as single-page sessions divided by total sessions. In Google Analytics 4 (GA4), the definition changed to sessions with no engagement event within ten seconds.
Segment by page type and traffic source before drawing conclusions. A blog bounce rate and a checkout bounce rate require completely different responses.
How it varies across Australia
Bounce rate varies enormously by page type and traffic source. Blog posts and single-page landing pages naturally attract higher bounce rates than product pages or multi-step flows. Comparing your overall site bounce rate against an industry average tells you almost nothing useful.

Bounce rate is one of the most misread numbers in digital analytics. The instinct is to treat it like a score: lower is better. That's wrong about half the time.
A visitor who lands on your pricing page, reads it for four minutes, then calls your sales number has technically bounced. A visitor who clicks through seven pages of your site buying nothing hasn't. The bounce rate counts the first as a failure and the second as a success. That tells you something about the limit of the metric.
Context is everything. Blog posts are expected to bounce. Visitors arrive from search, read what they needed, and leave. That's the content working. A product detail page that bounces heavily is a different story, and probably one worth investigating.
The second complication is that Google Analytics 4 quietly changed what bounce rate means. In Universal Analytics (UA), a bounce was any session with a single page view. In GA4, a bounce is any session with no engagement event within ten seconds. Same label, different maths. If your bounce rate looks dramatically different after migrating to GA4, that's why.
The number to watch alongside bounce rate is the page the session started on, the source of that traffic, and whether there was a conversion event on the bounced session. Those three filters usually tell a cleaner story than the headline rate.
A high bounce rate on a blog post might mean the reader got exactly what they came for. A high bounce rate on a checkout page means something is broken.
How to calculate it
Bounce Rate = Single-page sessions ÷ Total sessions × 100
Worked example. Your blog received 3,200 sessions last month. In 2,240 of those sessions, the visitor viewed only one page and left. Bounce Rate = 2,240 ÷ 3,200 × 100 = 70%. For a content-driven blog, that may be expected. For a product landing page with the same numbers, it warrants investigation.
The Australian context
Australian sites often see higher mobile bounce rates than desktop, partly because mobile page speeds in regional areas trail major cities. A site that performs well in Sydney can bounce heavily for a visitor loading it on a regional mobile connection. If your audience is geographically spread, segment bounce rate by device and check whether the mobile experience holds up.

Common questions
What is a good bounce rate?
It depends entirely on the page type. Content and blog pages commonly see rates in the high sixties to low eighties without it being a problem. Product pages, checkout flows and lead-gen pages should sit lower. Set targets by page type, not for the site as a whole.
Why did my bounce rate change after switching to GA4?
Because GA4 redefined the metric. Universal Analytics counted any single-page session as a bounce. GA4 counts a session as a bounce only if there is no engagement event within ten seconds. The two numbers are not comparable. Build a new baseline from your GA4 data.
Can someone bounce and still convert?
Not in the traditional sense, since a conversion event would prevent the session being counted as a bounce in GA4. But in Universal Analytics, a visitor could complete a form on a single page and still register as a bounce. Another reason the metric needs context.
How do I reduce bounce rate on a product page?
Start with page speed, mobile experience and above-the-fold clarity. If visitors leave before engaging, they either didn't find what they expected or something broke before it loaded. Check Core Web Vitals first, then audit whether the page matches the intent of the traffic source sending visitors to it.
