Why this matters for the Core Web Vitals, and where to start fixing it

Cumulative Layout Shift measures how much the page moves around while it loads. A button jumps just as someone goes to tap it, an ad pushes the article down, the text reflows when a late font arrives. Every one of those is a layout shift, and they add up into a score that reflects how stable the page feels. Unlike the other vitals, CLS is rarely about speed and almost always about reserving space.

Start by giving everything that loads late a place to land. Set width and height on images and video so the browser reserves the box before the file arrives. Reserve space for ads, embeds and banners instead of letting them push content. Load fonts so the fallback and the web font take the same room, and keep animations on transform rather than properties that trigger layout.

How are sites doing on CLS?

87.8% of sites have a good CLS. The typical site sits at 0.03 at the 75th percentile; the worst 1% reach 0.64.
