🎯 Core Web Vitals Explained
Largest Contentful Paint (LCP)
Measures loading performance. Should be 2.5 seconds or less. This is the time it takes for the main content of your page to load.
- Good: ≤ 2.5s
- Needs Improvement: 2.5s - 4.0s
- Poor: > 4.0s
First Input Delay (FID)
Measures interactivity. Should be 100 milliseconds or less. This is the time between a user's first interaction and the browser's response.
- Good: ≤ 100ms
- Needs Improvement: 100ms - 300ms
- Poor: > 300ms
Cumulative Layout Shift (CLS)
Measures visual stability. Should be 0.1 or less. This measures how much your page layout shifts during loading.
- Good: ≤ 0.1
- Needs Improvement: 0.1 - 0.25
- Poor: > 0.25
