Lazy loading

This filter works with the Largest Contentful Paint metric

This filter will indicate whether the LCP resource appears lazy-loaded, based on native loading attributes or (CSS/JS) lazy-loading patterns. Use for LCP Load Delay. Lazy-loaded LCP images usually start too late.

Although lazyloading above-the-fold images can be good practice, lazyloading your Largest Contentful Paint candidates certainly is not. With this filter, you can easily see which URLs and/or templates an LCP image is lazyloaded on.
