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.

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.

Note: When a visitor performs a custom event like downloads a file, types a query in a search, or signs up for a newsletter on the entry page, the bounce will be counted.

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.
