Bounce rate: what it meant, what it means now
In the old Universal Analytics, a bounce was a visit that viewed one page and left, regardless of how long they stayed. Someone who read your whole pricing page for four minutes and then rang you was a bounce. That is why the number was always misleading and why Google dropped it as a headline metric when GA4 replaced Universal Analytics in July 2023.
GA4 measures engagement instead. A session is engaged if it lasted more than ten seconds, or triggered a conversion, or viewed two or more pages. Bounce rate in GA4 is simply the inverse of engagement rate, and it is hidden by default because Google would rather you looked at engagement.
| Universal Analytics (to July 2023) | Google Analytics 4 | |
|---|---|---|
| A bounce is… | A session that viewed one page | A session under 10 seconds with no conversion and one page |
| Reading a page for 4 minutes then ringing | Bounce | Engaged, not a bounce |
| Shown by default? | Yes, prominently | No; engagement rate is shown instead |
| Useful for… | Very little | Spotting pages people leave instantly, which usually means the wrong visitors or a slow load |

So what is a good bounce rate?
It depends on what the page is for, which is why the question has no honest single answer. A guide that answers a question in the first paragraph may be left in eight seconds by a satisfied reader. A contact page that shows the phone number will be left by everyone who then rings. A product listing should keep people clicking. Judge each page against its job.
- Very high bounce on a page that should lead somewhere (a service page, a category) usually means the wrong visitors arrived, or the page loaded slowly, or the first screen did not match what they searched.
- High bounce on a page that answers a question or shows a phone number is often fine. Check calls and enquiries instead.
- A sudden change in bounce rate on a page that has not changed is a tracking problem before it is a visitor problem.
Conversion rate: the one that matters
Conversion rate is the share of visitors who do the thing the page exists for: send the form, ring the number, buy, book. It is the multiplier on every other number. Double it and every pound spent on traffic buys twice the enquiries.
| Situation | Rate | Where the figure comes from |
|---|---|---|
| Enquiry-led small business site, as commonly quoted | Around 1–3 in 100 | Industry benchmarks we have not verified; treat as a shape, not a target |
| Van leasing site, after rebuild | Roughly 4 in 100 | Reported by the client (Kris, Director, Vehicles 2 Lease); not measured by us |
| Same site before rebuild | Roughly 1 in 100 | Reported by the client |
| Page ranking for information or DIY searches | Near 0 | Search Console query intent on client sites; these readers were never buyers |

A site-wide conversion rate is nearly meaningless, because it averages a how-to article at zero with a quote page at eight. Measure per page, per full calendar month, and compare the page with its own previous months.
How to measure it without fooling yourself
- Define the conversions: form submitted, phone number tapped, booking made, purchase. Set each up as a key event in GA4 and, if you run adverts, import them there. The GA4 guide on this site walks through it.
- Record the source of every enquiry that arrives by phone or email, by asking. Analytics cannot see a phone call unless you instrument it.
- Read conversions per page, per full month. A landing page with 200 visitors and 8 enquiries is a 4% page; the homepage with 2,000 visitors and 8 enquiries is a 0.4% page and probably fine, because it is not where people convert.
- Compare the page with itself after a change: a shorter form, a visible price, a phone number moved up. That is conversion rate optimisation, and it is the cheapest growth work there is.
