# Core Web Vitals

**Category:** Technical SEO | **Updated:** 2026-03-05

Core Web Vitals are a set of three Google metrics — LCP, CLS, and INP — that measure real-world user experience for loading performance, visual stability, and interactivity.

## What Are Core Web Vitals?
Core Web Vitals (CWV) are three specific metrics that Google uses to measure user experience: **Largest Contentful Paint (LCP)** for loading speed, **Cumulative Layout Shift (CLS)** for visual stability, and **Interaction to Next Paint (INP)** for responsiveness. They are part of Google's page experience ranking signals.

## Why Core Web Vitals Matter for SEO
Google confirmed that Core Web Vitals are a ranking factor. Pages with good CWV scores may receive a ranking boost over pages with poor scores, all else being equal. Beyond SEO, good CWV scores correlate with better user engagement, lower bounce rates, and higher conversion rates.

## How to Measure and Improve
Measure CWV using Google PageSpeed Insights, Chrome DevTools, Lighthouse, or the CrUX report in Search Console. Improve LCP by optimizing images and server response time. Improve CLS by setting image dimensions and avoiding dynamic content injection. Improve INP by reducing JavaScript execution time.
