Page speed and user experience are direct Google ranking factors. Passing Core Web Vitals (LCP, INP, CLS) is required for maintaining top ranking positions in competitive niches.
Optimizing Largest Contentful Paint (LCP)
LCP must be under 2.5 seconds. Key optimizations include preloading hero images with fetchpriority=”high”, eliminating render-blocking JavaScript, and implementing edge CDN caching.
Minimizing Interaction to Next Paint (INP)
INP replaced FID as the definitive metric for responsiveness. Reduce main-thread blocking by deferring heavy third-party tracking scripts and breaking up long tasks.
Zero Cumulative Layout Shift (CLS)
Always specify explicit width and height dimensions on all images, video players, and dynamic banners to prevent layout jumps during page rendering.
