What is CLS by competitor

CLS by competitor shows how Cumulative Layout Shift (CLS) compares to key competitors in your industry. It gives you a clear view of whether you're delivering a more visually stable experience—or falling behind—in the race for user trust and engagement.

This lens helps you move beyond internal metrics to see how your layout stability ranks against others targeting the same audience.

Healthy CLS by competitor sample

A healthy view shows your CLS performing better or equal to your competitors.

If your values are greener or equally green across the chart, it means users are enjoying a stable browsing experience—and you’re not losing ground due to frustrating layout shifts. That stability helps reinforce trust, reduce misclicks, and improve engagement.

Unhealthy CLS by competitor sample

When your CLS is worse than your competitors’, it’s a signal that your layout is shifting too much during load or interaction—something users (and Google) notice.

Common causes include:

  • Content resizing after load (e.g., late-loaded fonts or banners).

  • Sticky headers or footers pushing content unexpectedly.

  • Ads or third-party widgets inserting late.

  • Carousels or sliders that shift layout on mount.

Even small differences can tilt user perception. If your competitor's experience feels more polished, users may choose them—even subconsciously.

Resolving unhealthy CLS by competitor

Go-to action plan to resolve an unhealthy CLS by competitor:

  1. Ask Uxi to analyze your CLS by competitor values and suggest improvements

  2. Use Filters to isolate the templates, devices, or countries where you’re falling behind.

  3. Simulate CLS of the suspected lens to see if fixing it will resolve the CLS by competitor. If yes, this is where the resolution focus should be.

  4. Use an automated CLS optimization tool like Navigation AI to improve your CLS by competitor values

  5. Once you’ve improved CLS, set an alert to be the first to know if it starts worsening again.
