What is Cumulative Layout Shift (CLS)?
A Core Web Vital that measures how much the page layout jumps around during loading. Lower is better — Google considers CLS under 0.1 "good."
High CLS scores come from images without dimensions, late-loading fonts, and ads that get inserted after page load. Setting explicit width and height on all images is the simplest fix.
