Calculate your website's bounce rate based on Google Analytics metrics.

Website Bounce Rate

What is Google Bounce Rate?

In traditional Google Analytics (Universal Analytics), Bounce Rate is the percentage of single-page sessions in which there was no interaction with the page. A bounced session has a duration of 0 seconds because the user triggers only a single request to the Analytics server, such as when a user opens a single page on your site and then exits without triggering any other requests.

The Formula for Bounce Rate

The mathematical formula used by this calculator is:

Bounce Rate = (Single-Page Sessions / Total Sessions) × 100

Example Calculation

If your blog post received 2,500 total sessions last month, and 1,200 of those visitors left the site after viewing only that page without clicking any internal links or buttons, your calculation would be:

  • Single-Page Sessions: 1,200
  • Total Sessions: 2,500
  • Calculation: (1,200 / 2,500) = 0.48
  • Bounce Rate: 48%

Bounce Rate vs. Engagement Rate in GA4

It is important to note that Google Analytics 4 (GA4) handles this metric differently. In GA4, Bounce Rate is the inverse of Engagement Rate. A "bounce" in GA4 is a session that was NOT an "engaged session." An engaged session is defined as a session that lasts longer than 10 seconds, has a conversion event, or has at least 2 pageviews.

What is a "Good" Bounce Rate?

While "good" varies by industry, here are general benchmarks for Universal Analytics:

  • 26% – 40%: Excellent (usually found on highly optimized landing pages).
  • 41% – 55%: Average (standard for most content-heavy sites).
  • 56% – 70%: Higher than average, may require investigation.
  • 70%+: Generally high, unless the site is a blog or news site where users read one article and leave.

How to Reduce Your Bounce Rate

If your bounce rate is too high, consider these SEO and UX improvements:

  • Improve Page Load Speed: Slow sites frustrate users and cause immediate exits.
  • Match Search Intent: Ensure your content actually answers the query the user searched for.
  • Mobile Optimization: A poor mobile experience is a leading cause of high bounce rates.
  • Clear Call-to-Action (CTA): Give users a clear next step to take on your site.
  • Internal Linking: Guide users to related content to keep them engaged within your ecosystem.
