CLS
One of Google's Core Web Vitals, measuring the degree of unexpected visual element displacement during page loading. The recommended value is below 0.1. Its impact is particularly significant in AI agent scenarios.

The selectable Speed Insights metrics include Real Experience Score, LCP and CLS.
The Real Experience Score is the core metric provided by Speed Insights, computed as a score from 0 to 100 based on real user monitoring data that combines Core Web Vitals such as FCP, LCP, FID and CLS.
LCP measures the time for the largest content element in the page viewport to finish rendering, and CLS quantifies the degree of unexpected movement of visual elements during page load; both are members of Google's Core Web Vitals system.
LCP, INP, and CLS are the three Core Web Vitals metrics in Google Web Vitals, measuring loading speed, interaction responsiveness, and visual stability, respectively.
CLS (Cumulative Layout Shift) measures visual stability, with a target of ≤0.1
Core Web Vitals currently includes three core dimensions—LCP, INP, and CLS—with ideal values of LCP within 2.5 seconds, INP below 200 milliseconds, and CLS below 0.1.
