Google's Cumulative Layout Shift (CLS) metric is intended to measure how janky or visually unstable your pages are. One of the big challenges with CLS is understanding which elements actually moved on the page, when they moved, and by how much. To help you with debugging your CLS scores, we show you visuals for each layout shift and how each individual shift adds up to the final cumulative metric. In this video, we show you how to quickly diagnose layout shifts for your site.
