Website Speed & Core Web Vitals: Impact on SEO
6 min read · February 10, 2026
With Google's 2021 Core Web Vitals update, page experience became an official ranking factor. LCP, INP and CLS metrics now directly affect search rankings.
LCP (Largest Contentful Paint)
Measures the loading time of the main content of the page. An LCP score below 2.5 seconds is considered 'Good'. Priority loading of hero images and CDN usage improves LCP.
INP (Interaction to Next Paint)
Measures response time to user interactions. Reducing JavaScript execution time and optimizing third-party scripts improves INP.
CLS (Cumulative Layout Shift)
Measures visual shifts that occur while the page loads. Setting fixed dimensions on images and reserving ad slots reduces CLS.
At Nimedya, we keep all Core Web Vitals metrics in the green zone on our websites using Next.js 16, static generation and image optimization techniques.
