What is bounce rate?

Bounce rate is the percentage of visitors who left your website after viewing only one page. But there’s a slight nuance to how the bounce is counted.

If the visitor completes a set goal or buys a product (ecommerce conversion), the bounce will not be counted, even though the visitor viewed only one page.

Bounce rate is counted in this way:

Bounce rate = (Bounces / Sessions) * 100%

Bounces: The number of sessions during which visitors viewed an entry page but didn’t continue to another page view, goal conversion, or ecommerce conversion. If a visitor performes a download, search, or other custom event and leaves the entry page, the session will be counted as bounced.

To make it more clear for you, here’s an example:

  • Somebody visits page A > completes a goal
  • Somebody visits page A
  • Somebody visits page A > page B
  • Somebody visits page A

The bounce rate for page A is 50%. Four sessions started with page A and during two sessions (2 and 4) visitors didn’t move to another page nor performed any further actions.

In Piwik PRO, we also use a metric called a page bounce rate. This is an accurate metric for counting bounce rate for a page URL or page title.

Page bounce rate = (Bounces / Entries) * 100%

Page bounce rate: An accurate bounce rate for a page URL or page title. The percentage of sessions during which visitors viewed only that page and didn’t continue to another page view, goal conversion, or ecommerce conversion.
