Google's Core Web Vitals measure the real-world user experience of a web page across three critical pillars: loading speed (LCP), visual stability (CLS), and interactivity (INP).
Achieving 100/100 Lighthouse performance scores requires systematic optimization of network requests, rendering pipelines, and main-thread JavaScript execution.
1. Fixing Largest Contentful Paint (LCP)
LCP measures when the main hero content or image becomes visible to the user. A good LCP score is 2.5 seconds or faster.
- Preload LCP images using <link rel='preload' fetchpriority='high' as='image'>.
- Self-host web fonts and use font-display: swap.
- Eliminate render-blocking CSS and JavaScript scripts.
2. Eliminating Cumulative Layout Shift (CLS)
CLS measures unexpected visual shifts during loading. A good CLS score is 0.1 or lower.
Always reserve static height containers for dynamic elements such as banner ads, cookie consent popups, and async user notifications.
3. Optimizing Interaction to Next Paint (INP)
INP replaced FID in 2024 as Google's official interactivity metric, measuring how quickly a page responds to user clicks, taps, and keypresses.
