What is CLS by product

CLS by product measures visual stability on the product page funnel point, showing the Cumulative Layout Shift (CLS) while users view details, images, and pricing. It helps you detect layout movement that can disrupt browsing or trigger mis-clicks.

CLS by product sample

In a healthy view, images, pricing, and CTAs remain stable — even as reviews, recommendations, or inventory messages load.

Unhealthy CLS by product

If CLS is poor, late-loading banners, size charts, recommendations, or price updates may push content down, causing frustration.

Resolving unhealthy CLS by product

Go-to action plan to resolve an unhealthy CLS by product:

  1. Ask Uxi to analyze your CLS by product values and suggest improvements

  2. Use Filters to identify specific product templates or dynamic elements causing instability.

  3. Simulate CLS of the suspected breakdown to see if fixing it will resolve the CLS by product. If yes, this is where the resolution focus should be.

  4. Use an automated CLS optimization tool like Navigation AI to improve your CLS by product values

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