What is PLS by Navigation AI impact

PLS by Navigation AI impact compares Perceived Load Speed (PLS) between two types of navigations: Standard and Optimized. Standard navigations occur without any prerendering assistance, while Optimized navigations are powered by Uxify’s Navigation AI — which predicts where users will go next and prerenders those pages before they’re even clicked.

This lens helps quantify how much faster the experience feels when Navigation AI is active, and how much user-perceived performance is improved by eliminating traditional load delays.

Should you worry

A healthy chart will show that Optimized navigations consistently deliver faster PLS values than Standard ones — often dramatically so. Optimized sessions should cluster in the lowest (fastest) PLS ranges, while Standard ones may span a broader range.

If there’s little difference between the two — or worse, if Optimized feels just as slow — it suggests your pages aren’t prerender-friendly or that heavy content is still blocking fast rendering.

Unhealthy PLS by Navigation AI impact sample

When Standard navigations take too long to load, users feel the delay — and it can reduce the impact of even your Optimized ones. Since both rely on shared resources (scripts, images, styles), slow Standard performance can bleed into the experience of prerendered pages.

This results in higher-than-expected PLS values for both types, minimizing the “instant” feel you want from Navigation AI and reducing its ability to boost engagement.

Resolving unhealthy PLS by Navigation AI impact

Go-to action plan to resolve an unhealthy PLS by Navigation AI impact:

  1. Ask Uxi to analyze your PLS by Navigation AI impact and suggest improvements.

  2. Use Filters to isolate slow Standard navigations and analyze their bottlenecks.

  3. Simulate LCP of the suspected lens to see if fixing it will resolve the PLS by Navigation AI impact. If yes, this is where the resolution focus should be.

  4. Use an automated optimization tool like Navigation AI to improve your PLS by Navigation AI impact.

  5. Once you’ve improved PLS, set an alert to be the first to know if it starts worsening again.
