Definition
Bounce rate is the percentage of visitors who land on a page of your website and leave without taking any further action — no clicking to another page, no filling in a form, no scrolling to engage. They arrived, saw one page, and left. It is expressed as a percentage: if one hundred people visit your homepage and fifty-five leave without doing anything else, your bounce rate is fifty-five per cent.
Why It Matters
A high bounce rate can be a warning sign. It might mean your page is slow to load, the content does not match what the visitor expected, the design is confusing, or there is no clear next step. But context matters. A blog post that answers a question completely might have a high bounce rate simply because the visitor got what they needed — that is not necessarily a problem. Where bounce rate becomes concerning is on pages designed to drive action, such as service pages, landing pages, or product pages. If visitors are leaving those pages immediately, something is failing: the messaging, the layout, or the user experience. Monitoring bounce rate alongside other metrics like time on page and conversion rate gives a clearer picture.
Example
A consultancy drives traffic to a service page through Google Ads. The page has a bounce rate of eighty per cent. On investigation, the page takes six seconds to load on mobile and the headline does not match the ad copy. After improving the load speed and aligning the messaging, the bounce rate drops to forty-five per cent, and enquiry form submissions double.
