What is PLS by visitor ID
PLS by visitor ID lists anonymized visitor IDs and the Perceived Load Speed (PLS) each one felt across visits—color-coded to indicate how “ready” the page appeared to them. It highlights whether returning users consistently perceive the site as fast.
Perceived Load Speed (PLS) is a Uxify metric reflecting when the page looks ready, considering all meaningful on-screen elements.
PLS by visitor ID sample
Should you worry
Mostly green IDs mean returning users perceive pages as ready almost immediately—confidence stays high and engagement follows.
Unhealthy PLS by visitor ID sample
Yellow/red IDs indicate visitors repeatedly see incomplete UI (late hero images, empty panels, placeholders), even if technical metrics look fine—hurting trust and intent.
Resolving unhealthy PLS by visitor ID
Go-to action plan to resolve an unhealthy PLS by visitor ID:
Ask Uxi to analyze your PLS by visitor ID and suggest improvements.
Use Filters to compare first vs. subsequent visits; verify perceived speed improves with caching.
Simulate LCP of the suspected breakdown to see if fixing it will resolve the PLS by visitor ID. If yes, this is where the resolution focus should be.
Use an automated optimization tool like Navigation AI to improve your PLS by visitor ID.
Once you’ve improved PLS, set an alert to be the first to know if it starts worsening again.
