Google is announcing Core Web Vitals will become ranking signals in May 2021 in an update that will also combine existing UX-related signals.
The ‘page experience’ signal combines Core Web Vitals with the following signals:
- Intrusive interstitial guidelines
Core Web Vitals were introduced earlier this and are designed to measure how users experience the speed, responsiveness, and visual stability of a page.
Specifically, these are defined as the Core Web Vitals:
- Largest Contentful Paint: The time it takes for a page’s main content to load. An ideal LCP measurement is 2.5 seconds or faster.
- First Input Delay: The time it takes for a page to become interactive. An ideal measurement is less than 100 ms.
- Cumulative Layout Shift: The amount of unexpected layout shift of visual page content. An ideal measurement is less than 0.1.
