What is LCP by session duration
LCP by session duration lens breaks down your Largest Contentful Paint (LCP) based on how long users stay on your site. Segmented by session durations (0s, 30s, 60s, 120s, 240s, 480s, and 960s+), it reveals whether load performance correlates with how long users engage.
LCP measures how fast the largest visible element loads — usually a hero image or main heading. Poor LCP early in the session may drive users away, while fast LCP tends to support longer engagement.
Healthy LCP by session duration sample
Should you worry
A healthy LCP by session duration shows green across all segments. If shorter sessions like 0s or 30s are still green, users are likely not leaving due to slow loading. Longer sessions maintaining good LCP indicate scalable performance over time.
Unhealthy LCP by session duration sample
If early durations like 0s or 30s are yellow or red, it suggests users are bouncing due to slow load times. Conversely, degraded LCP in longer sessions may indicate performance regressions from accumulated scripts, ads, or personalization layers.
Resolving unhealthy LCP by session duration
Go-to action plan to resolve an unhealthy LCP by session duration:
Ask Uxi to analyze your LCP by session duration values and suggest improvements.
Use Filters to isolate slow durations and check related pages and devices.
Simulate LCP of the suspected lens to see if fixing it will resolve the slow LCP by session duration. If yes, this is where the resolution focus should be.
Use an automated LCP optimization tool like Navigation AI to improve your LCP by session duration values.
Once you’ve improved LCP, set an alert to be the first to know if it starts worsening again.
