Core Web Vitals 2026: The Optimization Guide
Core Web Vitals (LCP, INP, CLS) are Google ranking signals. A slow, unstable site penalizes SEO and degrades user experience. Here's how to optimize them in 2026.
LCP: Largest Contentful Paint
LCP measures the loading of the main element (hero image, text block). Target: less than 2.5 seconds. Optimize images (WebP, lazy loading), server and client-side rendering.
INP: Responsiveness to Interactions
INP (Interaction to Next Paint) replaces FID. It measures site responsiveness to clicks and inputs. Reduce blocking JavaScript, optimize event listeners and delegate heavy tasks.
CLS: Visual Stability
CLS (Cumulative Layout Shift) evaluates layout shifts. Set width/height on images and videos, avoid dynamic content insertion above the fold. Target: CLS below 0.1.
Measurement and Monitoring
Use PageSpeed Insights, Search Console and tools like Web Vitals to measure performance. Track trends and fix regressions. A Geneva technical SEO agency can audit and optimize your site.
