Core Web Vitals 2026: Improving LCP, INP, and CLS
Core Web Vitals are three metrics measuring real user experience: how fast content appears, how fast the page responds to interaction, and how visually stable the layout is.
Core Web Vitals metrics: LCP, INP, CLS
ideal LCP target per Google recommendations
ideal CLS target value
LCP (Largest Contentful Paint) measures when the largest visible element appears, INP (Interaction to Next Paint) measures how fast the page responds to user interaction, and CLS (Cumulative Layout Shift) measures how visually stable elements stay while loading.
Improving LCP
Use the next/image component to auto-optimize images, load the page's most important font and image with high priority, and avoid blocking render with heavy unnecessary above-the-fold CSS/JS.
Improving INP and CLS
Break up heavy JavaScript tasks to avoid blocking the main thread, and pre-set image and ad dimensions (width/height) to prevent sudden content shifts while loading.
Questions & Answers
Is Core Web Vitals a direct Google ranking factor?
Yes, it's part of "Page Experience" which affects rankings, but it's not the only or always the most important factor.
What's the difference between INP and the old FID?
INP replaced FID because it measures responsiveness across all interactions during the page's lifetime, not just the first one.
