What is CLS by multipage sessions
CLS by multipage sessions lens reveals layout shift behavior during multipage sessions. Cumulative Layout Shift (CLS) measures how stable a page appears while loading. This lens compares the experience between Not MPSR and MPSR segments.
A high CLS means users are seeing unexpected jumps in content, especially annoying during product exploration or checkout.
Healthy CLS by multipage sessions sample
Multipage sessions should ideally have low CLS — poor layout stability across several pages disrupts trust and continuity. If you notice higher CLS for MPSR, investigate unstable UI elements like sliders, injected ads, or dynamically resized content.
Unhealthy CLS by multipage sessions sample
High CLS on MPSR could signal problems with how components behave across journey steps (e.g., consistent layout bugs on product or category pages). If Not MPSR is unstable, it may block deeper engagement from the start.
Resolving unhealthy CLS by multipage sessions
Go-to action plan to resolve an unhealthy CLS by multipage sessions:
Ask Uxi to analyze your CLS by multipage sessions values and suggest improvements
Use Filters to pinpoint layout instability during return or multipage sessions.
Simulate CLS of the suspected lens to see if fixing it will resolve the CLS by multipage sessions. If yes, this is where the resolution focus should be.
Use an automated CLS optimization tool like Navigation AI to improve your CLS by multipage sessions values
Once you’ve improved CLS, set an alert to be the first to know if it starts worsening again.
