What is CLS by session pageviews
CLS by session pageviews shows Cumulative Layout Shift (CLS) grouped by how many pages a user visited during their session — starting from single-page visits up to deeper multi-page journeys.
This lens helps you see whether layout stability encourages users to keep browsing, or if shifts in layout contribute to early exits or friction during longer sessions.
Only data from real sessions during the selected period is shown.
Healthy CLS by session pageviews sample
A healthy distribution often shows:
Low CLS across all session depths
Slightly better CLS as users view more pages, suggesting a smooth browsing experience
Green bars in the 2+, 3+, and 4+ categories
This implies your layout is stable enough to encourage continued exploration — a sign your visual consistency holds up across the user journey.
Unhealthy CLS by session pageviews sample
In a problematic setup:
1-page sessions have high CLS, leading to bounce or user frustration
CLS stays bad even for 3+ page sessions, pointing to persistent layout instability
Longer sessions get worse, likely due to compounded layout shifts from late-loaded UI elements or ad injections
This hurts user trust and makes the site feel unpredictable.
Resolving unhealthy CLS by session pageviews
Go-to action plan to resolve an unhealthy CLS by session pageviews:
Ask Uxi to analyze your CLS by session pageviews values and suggest improvements
Use Filters to identify which landing pages correlate with high CLS in 1-page sessions or find hidden patterns for longer sessions.
Simulate CLS of the suspected lens to see if fixing it will resolve the CLS by session pageviews. If yes, this is where the resolution focus should be.
Use an automated CLS optimization tool like Navigation AI to improve your CLS by session pageviews values
Once you’ve improved CLS, set an alert to be the first to know if it starts worsening again.
