Full guide: definition, formula, and benchmarksWhy Page Load Time Impact matters for Google Analytics users
Every additional second of page load time reduces conversion rates. Studies consistently show that pages loading in 1-2 seconds convert at significantly higher rates than pages taking 5+ seconds. Yet many teams treat page speed as a technical concern disconnected from business metrics.
Mapping page load time into your metric tree alongside bounce rate and conversion metrics makes the business impact of performance visible. Statistical correlations quantify exactly how much revenue each second of load time costs, creating a compelling case for performance investment.

Bounce Rate
Web AnalyticsBounce Rate = (Single-Page Non-Engaged Sessions / Total Sessions) x 100
Bounce rate measures the percentage of Google Analytics sessions where the user viewed only a single page and triggered no additional events before leaving. In GA4, it is the inverse of engagement rate - a bounced session is one that was not engaged, meaning it lasted less than 10 seconds, had no conversion event, and had fewer than 2 page views.
View metricConversion Rate
Web AnalyticsConversion Rate = (Conversions / Sessions) x 100
Conversion rate measures the percentage of Google Analytics sessions or users that complete a defined conversion event - such as a purchase, signup, form submission, or key feature interaction. It quantifies how effectively your website turns visitors into customers or leads.
View metricSession Duration
Web AnalyticsAverage Session Duration = Total Session Time / Total Sessions
Session duration measures the average time users spend on your site during a single Google Analytics session. In GA4, it is calculated as the time between the first and last event in a session, providing a measure of how long users actively engage with your content.
View metricMobile vs Desktop Performance
Web AnalyticsMobile vs desktop performance compares Google Analytics engagement, conversion, and revenue metrics across device types. It identifies whether mobile and desktop users experience your site differently and quantifies the performance gap between devices.
View metricExit Rate
Web AnalyticsExit Rate = (Exits from Page / Total Page Views for Page) x 100
Exit rate measures the percentage of page views that were the last in a session for a specific page in Google Analytics. Unlike bounce rate, which considers only single-page sessions, exit rate applies to all sessions and identifies the pages where users most frequently end their visit.
