What is Page Speed?
Definition
Page speed measures how fast a web page loads and becomes interactive. It is assessed using metrics like Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS) — collectively known as Core Web Vitals.
Why It Matters
Google uses page speed as a ranking factor. Faster pages have lower bounce rates, higher conversions, and better user experience. Key optimizations include minification, compression, CDN usage, image optimization, and reducing JavaScript bundle size.
