What are Core Web Vitals?

Core Web Vitals are three official Google metrics measuring real user experience on a page: LCP (loading speed), CLS (visual stability), and INP (responsiveness to interaction). They're part of Google's Page Experience ranking signals.

LCP — Largest Contentful Paint

Measures how long it takes for the largest visible element (usually the hero image or headline) to render. Google's target: under 2.5 seconds. Unoptimized images and render-blocking scripts are the most common causes of poor LCP.

CLS — Cumulative Layout Shift

Measures unexpected layout movement while the page loads. Google's target: under 0.1. Images and ads without reserved dimensions are the usual cause of poor CLS.

INP — Interaction to Next Paint

Measures how quickly a page responds to a click or tap. Google's target: under 200 milliseconds. Heavy third-party scripts are a common cause of poor INP.

Mobile Matters Most

Mobile devices generally have less processing power and slower connections, making these metrics harder to hit — and more impactful once achieved, since Google primarily evaluates the mobile version of your site.

How to Measure

Google PageSpeed Insights and the Core Web Vitals report inside Search Console are the standard free tools for checking your current scores.
