What is Bounce Rate vs Engagement Rate?

The percentage of website visitors who leave after viewing only a single page, and how modern systems calculate engagement.

Traditionally, bounce rate represents the percentage of single-page sessions — visitors who land on a page and exit without clicking to another page or performing an action. It is a critical metric for measuring content relevance and landing page optimization.

Google Analytics 4 quietly redefined bounce rate. Instead of counting single-page sessions, GA4 defines bounce rate as the inverse of "Engagement Rate" (sessions that lasted longer than 10 seconds, had a conversion event, or viewed 2+ pages). Under this model, bounce rates frequently drop to a misleading 0% to 5% on dashboard reports.

TrackWhy computes bounce rate the honest way: the absolute share of sessions that recorded a single pageview. This gives you a realistic, actionable metric to optimize your landing page headlines, loading speeds, and user layouts.

FAQ

Frequently Asked Questions

Why is my GA4 bounce rate different from TrackWhy?
GA4 defines a session as engaged if a visitor stays for more than 10 seconds, even if they never click a link or convert. TrackWhy counts any single-page session as a bounce, regardless of duration, which reflects actual visitor navigation.
How can I optimize a high bounce rate?
To lower your bounce rate, focus on speed optimization (ensuring the site loads under 2 seconds), improving mobile layouts, and matching your landing page copy directly to referrer campaign headings.
