# SEO Technical: Core Web Vitals
Guides optimization of Core Web Vitals (CWV)—Google's user experience metrics that affect search ranking. CWV are confirmed ranking factors for mobile and desktop.
**When invoking**: On **first use**, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On **subsequent use** or when the user asks to skip, go directly to the main output.
## Scope (Technical SEO)
- **LCP** (Largest Contentful Paint): Loading performance; time to render largest content element
- **INP** (Interaction to Next Paint): Responsiveness; replaced FID on March 12, 2024
- **CLS** (Cumulative Layout Shift): Visual stability; unexpected layout shifts
## Target Thresholds (75th percentile, field data)
