What is CLS by checkout
CLS by checkout breaks down visual stability at the checkout funnel point, showing the Cumulative Layout Shift (CLS) users experience while reviewing totals and filling forms. It helps you catch movement that undermines trust or causes mis-clicks.
Healthy CLS by checkout
In a healthy view, checkout is green and stable. Fields, totals, and buttons don’t jump when promos, taxes, or shipping options load.
Unhealthy CLS by checkout
If CLS is poor, late-loading banners, error messages, dynamic totals, or third-party iframes may be pushing content, causing frustrating shifts during form entry.
Resolving unhealthy CLS by checkout
Go-to action plan to resolve an unhealthy CLS by checkout:
Ask Uxi to analyze your CLS by checkout values and suggest improvements
Use Filters to focus on scenarios with recalculations (coupons, shipping, taxes) that correlate with higher CLS.
Simulate CLS of the suspected breakdown to see if fixing it will resolve the CLS by checkout. If yes, this is where the resolution focus should be.
Use an automated CLS optimization tool like Navigation AI to improve your CLS by checkout values
Once you’ve improved CLS, set an alert to be the first to know if it starts worsening again.
