Sera CLS Guard

About this product

If you run AdSense or any auto-injected ads, your CLS score is suffering. Sera CLS Guard fixes the most common causes of layout shift with zero configuration and near-zero performance overhead. The plugin injects a tiny CSS payload under 1KB that pre-sizes ad containers, stabilizes anchor ads, and prevents vignette overlays from pushing your content around. It works with AdSense, Auto Ads, and most major ad networks out of the box. There is no JavaScript overhead, no render-blocking resources, and no complex configuration. Install it, activate it, and your CLS score improves immediately. For sites that need more control -- per-page overrides, analytics, learning mode, and auto-fixing -- upgrade to Sera AI CLS Guard.
