Search engines prioritize web pages that render rapidly, respond immediately to user interactions, and maintain visual layout stability. Google's Core Web Vitals metrics serve as a direct ranking signal across desktop and mobile search indices.
1. Largest Contentful Paint (LCP)
Measures perceived loading speed. Compressing hero images, utilizing responsive dimension attributes, and serving modern formats ensures your primary content appears within 2.5 seconds.
2. Cumulative Layout Shift (CLS)
Measures visual stability. Reserving explicit width and height dimensions on ad containers and media prevents jarring layout jumps when assets finish loading.
3. Interaction to Next Paint (INP)
Reflects page responsiveness. Moving heavy mathematical computations and file processing tasks to Web Workers keeps the browser main thread responsive and fluid.
