Core Web Vitals are the three metrics Google uses to measure real-world experience: how fast the main content loads (LCP), how quickly the page reacts to input (INP) and how much the layout jumps around while loading (CLS).
Passing them is mostly about discipline, not magic:
- Serve images in modern formats at the right size, and reserve their space to avoid layout shift.
- Defer non-critical JavaScript and avoid long tasks that block interaction.
- Cache aggressively at the edge so repeat visits are instant.
We treat these budgets as part of the build, not an afterthought, so the site ships fast on the first deploy instead of being “optimized” later.
