What is LCP by visitor ID
LCP by visitor ID lists anonymized visitor IDs (hash-like codes) and shows the Largest Contentful Paint (LCP) each one experienced during the selected period. Each row displays an ID, a color-coded status (green/yellow/red), and the visitor’s LCP value. This lets you see whether the same person enjoys consistently fast page loads across visits—or keeps running into slow ones.
Largest Contentful Paint (LCP) measures the time it takes for the largest visual element—typically a hero image or headline—to fully render.
LCP by visitor ID sample
Should you worry
A healthy view shows mostly green IDs with tight, low LCP values. That means caching, image sizing, and templates are reliable across first and repeat visits.
Unhealthy LCP by visitor ID
If you see many yellow/red IDs or the top bar dominated by slower statuses, certain visitors are repeatedly hitting heavy pages (large media, blocking scripts, redirects) or suffering device/network constraints.
Resolving unhealthy LCP by visitor ID
Go-to action plan to resolve an unhealthy LCP by visitor ID:
Ask Uxi to analyze your LCP by visitor ID values and suggest improvements.
Use Filters to compare first vs. repeat visits for the same IDs; check if LCP improves with caching.
Simulate LCP of the suspected breakdown to see if fixing it will resolve the slow LCP by visitor ID. If yes, this is where the resolution focus should be.
Use an automated LCP optimization tool like Navigation AI to improve your LCP by visitor ID values.
Once you’ve improved LCP, set an alert to be the first to know if it starts worsening again.
