How to calculate session duration
Why session duration matters for Google Analytics users
Longer sessions generally indicate deeper engagement, but the relationship between duration and conversion is not always linear. For e-commerce, shorter sessions with focused navigation may convert better. For content sites, longer sessions correlate with higher engagement and ad revenue.
Positioning session duration in your metric tree alongside conversion metrics reveals whether time on site predicts business outcomes for your specific context. Statistical correlations show the optimal engagement depth for conversion, informing content and UX strategy.
Understand and act on session duration with KPI Tree
KPI Tree syncs session duration data from your warehouse and tracks it per traffic source, landing page, and device. Position it alongside other engagement metrics in your tree.
Assign RACI ownership to your UX lead. Set alerts when average session duration drops on key pages and track experience changes against their impact on time-based engagement.

Pages per Session
Web AnalyticsMetric Definition
Pages per Session = Total Page Views / Total Sessions
Pages per session measures the average number of pages viewed during a single Google Analytics session. It indicates how deeply users engage with your site content and how effectively your navigation and internal linking guide users through multiple pages.
Bounce Rate
Web AnalyticsMetric Definition
Bounce 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.
Conversion Rate
Web AnalyticsMetric Definition
Conversion 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.
Content Performance Analysis
Web AnalyticsMetric Definition
Content performance analysis evaluates how individual pages and content types perform in Google Analytics across engagement, conversion, and revenue metrics. It identifies which content drives meaningful outcomes and which attracts traffic without contributing to business goals.
Exit Rate
Web AnalyticsMetric Definition
Exit 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.
