Exploring the future of Core Web Vitals
summary
Google plans concrete changes to Core Web Vitals: considering adding First Contentful Paint to capture early progressive paint, tightening First Input Delay from 100ms toward 75 or 50 milliseconds, and reworking Cumulative Layout Shift to account for shifts after load and for long‑lived pages. Metrics for single‑page app transitions, measuring every input and the full time until the screen updates, and new scrolling/animation jank signals are under study. Feedback is collected via web‑vitals‑feedback@googlegroups.com.
