Explore Session Duration using your PostHog data
Session Duration in PostHog
Session Duration analysis is crucial for PostHog users because it reveals how deeply engaged users are with your product. PostHog’s event-based tracking captures granular user interactions, session timestamps, and behavioral patterns that make average session duration calculations highly precise. This metric helps product teams identify feature stickiness, optimize onboarding flows, and determine what is a good session duration benchmark for different user segments or product areas.
However, manually analyzing session duration through PostHog’s interface or spreadsheets creates significant bottlenecks. PostHog’s built-in dashboards provide basic session metrics but lack the flexibility to segment by custom user properties, compare cohorts across time periods, or drill down into specific user journeys. You’re limited to pre-defined views that can’t answer nuanced questions like “How does session duration vary between users who completed onboarding versus those who didn’t?”
Spreadsheet analysis is even more problematic. Calculating session duration requires complex formulas to handle session boundaries, filter out bot traffic, and account for different timezone considerations. With thousands of events and multiple user segments to analyze, maintaining accurate calculations becomes error-prone and incredibly time-consuming.
Count eliminates these manual processes by automatically calculating session duration metrics from your PostHog data, enabling instant segmentation and exploration of the factors that drive longer, more valuable user sessions.
