Core Web Vitals Overview

Core Web Vitals are user experience metrics related to loading, interaction, and visual stability. They help identify pages that feel slow or unstable.

Key ideas

Large Contentful Paint relates to loading. Interaction to Next Paint relates to responsiveness. Cumulative Layout Shift relates to unexpected movement.

Why they matter

Visitors are more likely to stay when pages load quickly, respond smoothly, and do not jump around while reading or clicking.

Improve gradually

Optimize images, reduce script work, reserve layout space, and test real mobile conditions. Do not ignore content quality while chasing metrics.
