What is Bounce Rate?
Bounce rate is a critical web analytics metric that represents the percentage of visitors who enter your website and then leave ("bounce") rather than continuing to view other pages within the same site. Technically, a bounce is calculated as a single-page session. In the context of Google Analytics, if a user lands on your page and closes the tab or clicks back without triggering any other request to the analytics server, it counts as a bounce.
Understanding your bounce rate helps you evaluate the quality of your traffic and the effectiveness of your landing pages. A high bounce rate might indicate that the content is irrelevant to the user's search intent, or that the user experience (UX) is poor.
The Bounce Rate Formula
The calculation behind this metric is straightforward. The formula used by our Free Analytics Bounce Rate Calculator is:
(Total One-Page Visits / Total Entrance Visits) × 100 = Bounce Rate %
For example, if your homepage receives 1,000 visitors in a month, and 450 of them leave without clicking a second link, your bounce rate is 45%.
What is a Good Bounce Rate?
There is no single "correct" number for bounce rate, as it varies significantly by industry and website type. However, general benchmarks include:
- 26% to 40%: Excellent. This range is ideal for most retail and service-oriented sites.
- 41% to 55%: Average. This is a standard range for many websites.
- 56% to 70%: Higher than average. This may be acceptable depending on the website type but often suggests room for improvement.
- 70%+: High. Unless you run a blog, news portal, or dictionary site where users come for one specific answer, a rate this high usually signals issues with page load speed, design, or content relevance.
- Under 20%: Suspiciously low. If your calculator shows a number this low, check your analytics implementation. You may have duplicate tracking codes firing, causing every single-page visit to look like a two-page visit.
Common Causes of High Bounce Rates
If the calculator returns a high percentage, consider investigating these common issues:
- Slow Page Load Speed: If your page takes more than 3 seconds to load, users will leave before the site even renders.
- Misleading Title Tags: If your SEO meta title promises one thing but the content delivers another, users will bounce immediately.
- Poor Mobile Optimization: With mobile traffic often exceeding desktop, a non-responsive design will drive users away.
- Intrusive Pop-ups: Aggressive interstitials that block content upon entry lead to immediate exits.
- 404 Errors: Ensure your external links aren't pointing to broken pages.
Universal Analytics vs. GA4
It is important to note that the definition of "Bounce Rate" has evolved. In the classic Universal Analytics, it was strictly about single-page sessions. In Google Analytics 4 (GA4), the concept has been inverted into "Engagement Rate." In GA4, a bounce is simply the inverse of an engaged session. An engaged session is one that lasts longer than 10 seconds, has a conversion event, or has at least 2 pageviews. Our calculator uses the classic formula which remains the industry standard for general web analysis.
