What is CLS by pageviews per session
CLS by pageviews per session lens uncovers layout instability across session depth. Cumulative Layout Shift (CLS) tracks how much elements unexpectedly move as the page loads — a critical UX factor.
As users navigate further, poor CLS can build friction and erode trust — especially during critical pages like cart or checkout.
Healthy CLS by pageviews per session sample
Low CLS across all session lengths signals a smooth and visually stable journey. Minor fluctuations between session lengths are okay, but red or yellow in deeper segments should trigger investigation.
Unhealthy CLS by pageviews per session sample
If CLS increases in longer sessions, investigate shifting UI components (like banners, carousels, or injected offers) on deeper pages. High CLS for 1-page sessions could indicate unstable landing or promo pages.
Resolving unhealthy CLS by pageviews per session
Go-to action plan to resolve an unhealthy CLS by pageviews per session:
Ask Uxi to analyze your CLS by pageviews per session values and suggest improvements
Use Filters to isolate shifts happening after 2–3 pageviews.
Simulate CLS of the suspected lens to see if fixing it will resolve the CLS by pageviews per session. If yes, this is where the resolution focus should be.
Use an automated CLS optimization tool like Navigation AI to improve your CLS by pageviews per session values
Once you’ve improved CLS, set an alert to be the first to know if it starts worsening again.
