What is CLS by US state
CLS by US state shows Cumulative Layout Shift (CLS) segmented by the US states where your visitors are located. It helps you identify which states experience more layout instability, often tied to slower connections or device limitations.
You’ll only see US states that generated traffic during the selected time period and device type.
Poor CLS in certain US states usually means users there are:
On slower or unstable connections that delay layout-critical assets
Using devices with less rendering power
Affected by late-loading components (like banners or fonts) shifting the layout
This instability can increase frustration, raise bounce rates, and hurt your conversion rates in those regions.
Healthy CLS by US state ratio sample
If most high-traffic states are green, your layout performs consistently well across the country. Slight differences are okay — but no state should be deep yellow or red.
Unhealthy CLS by US state sample
If high-traffic states like California or New York show poor CLS, it can significantly affect your overall metrics. Common causes include:
Delayed ads or banners pushing content down
Slow-loading fonts or components
Personalization scripts executing late
Heavy layouts reacting poorly on weaker devices
Even healthy design can fail if delivery is unstable.
Resolving unhealthy CLS by US state
Go-to action plan to resolve an unhealthy CLS by US state:
Ask Uxi to analyze your CLS by US state values and suggest improvements
Use Filters to drill into the slowest states and check for patterns across device types or connection speeds.
Simulate CLS of the suspected lens to see if fixing it will resolve the CLS by US state. If yes, this is where the resolution focus should be.
Use an automated CLS optimization tool like Navigation AI to improve your CLS by US state values
Once you’ve improved CLS, set an alert to be the first to know if it starts worsening again.
