What is CLS by error clicks
CLS by error clicks shows how Cumulative Layout Shift (CLS) differs for sessions where users encounter error clicks compared to sessions without them.
An error click occurs when a user interacts with an element but the outcome fails — such as clicking a broken link, submitting a form that throws an error, or pressing a button that doesn’t respond as expected. These clicks reflect technical breakdowns that disrupt the intended user flow.
This breakdown helps you see whether unstable layouts (high CLS) are contributing to failed interactions. If elements shift unexpectedly, users may click the wrong target or trigger actions before the page is ready, leading to errors.
CLS by error clicks sample
In a healthy view, CLS values for error click sessions remain similar to those without errors. Errors may still occur, but they stem from backend issues or validation logic — not layout instability.
A healthy setup typically shows:
CLS consistently below 0.1 for both groups.
No significant visual shifts during interaction.
Clear and stable targets for buttons, links, and forms.
If CLS is stable and low, error clicks are likely a functional issue, not a performance problem.
Unhealthy CLS by error clicks
If sessions with error clicks show higher CLS values, unstable layouts may be causing failed interactions.
Common causes include:
Buttons or links shifting position just as users click.
Forms moving or resizing before submission, causing missed targets.
Late-loading ads or widgets pushing interactive elements unexpectedly.
Font swaps or style changes creating click misalignment.
Here, layout instability directly increases the likelihood of error-triggering clicks.
Resolving unhealthy CLS by error clicks
Go-to action plan to resolve an unhealthy CLS by error clicks:
Ask Uxi to analyze your CLS by error clicks values and suggest improvements
Use Filters to compare sessions with error clicks by device, country, or traffic type.
Simulate CLS of the suspected breakdown to see if fixing it will resolve the CLS by error clicks. If yes, this is where the resolution focus should be.
Use an automated CLS optimization tool like Navigation AI to improve your CLS by error clicks values
Once you’ve improved CLS, set an alert to be the first to know if it starts worsening again.
