IMPROVE CLS
WEBSITE STABILITY

Cumulative Layout Shift (CLS) is one of Google’s Core Web Vitals, directly impacting your site’s user experience and search rankings. To improve CLS website scores, you must eliminate unexpected shifts that push content around as the page loads. Common culprits include images without dimensions, dynamically injected ads, and web fonts that cause flash of invisible text. A single bad shift can frustrate users and increase bounce rates — making CLS optimization essential for any modern website.

The first step to improve CLS website stability is auditing your current layout shifts. Tools like Lighthouse, PageSpeed Insights, and Chrome DevTools quantify CLS and pinpoint problem elements. At IRPR Agency, we use these diagnostics alongside our own custom scripts to identify every shift source. By measuring baseline scores, we create a targeted action plan that addresses both major and minor contributors to layout instability.

Once the issues are mapped, we implement a combination of technical fixes. Setting explicit width/height on images and videos is the lowest-hanging fruit — it alone can reduce CLS by over 50% on media-heavy pages. We also reserve space for ads using placeholder containers, switch to transform-based animations, and preload critical fonts with font-display: swap. Each technique is tested in a staging environment to ensure no new shifts are introduced while we improve CLS website performance.

Beyond the quick fixes, IRPR dives deeper into your site’s architecture. For single‑page applications and dynamic content feeds, we restructure JavaScript injection to occur within fixed containers rather than inline flows. We also apply CSS containment (contain: layout style) to isolate the layout scope of specific components. These advanced methods ensure that even complex interactions — like infinite scroll or live chat — do not degrade your CLS score. The result is a seamless, predictable browsing experience that delights users and search engines alike.
