# Page Speed Optimization: Practical Wins That Move Core Web Vitals Service‑business websites live or die by the leads they generate. When a potential customer lands on a page that loads slowly, they often leave before the form even appears. Core Web Vitals — Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS) — are the metrics Google uses to quantify that experience.
