Overview
Core Web Vitals measure real-world user experience regarding loading speed, visual stability, and interactivity. Google incorporates these performance metrics directly into its ranking algorithms as critical components of overall page experience.
Key Performance Metrics
- Largest Contentful Paint (LCP): Optimising server response times and asset delivery so the primary visible page element loads within 2.5 seconds.
- Interaction to Next Paint (INP): Reducing main-thread JavaScript blocking time to ensure the website responds instantly to user clicks, taps, and key presses.
- Cumulative Layout Shift (CLS): Locking down element dimensions and reserving precise space for ads, banners, and dynamic images to prevent jarring visual shifts while pages load.
