Core Web Vitals are three measurements Google uses to judge how good your page feels to real visitors. They cover loading, interactivity, and visual stability. You can read Google's official guide at web.dev/vitals.
The Three Core Web Vitals
| Metric | What It Measures | Good Score |
|---|---|---|
| LCP (Largest Contentful Paint) | How fast the main content loads | 2.5 seconds or less |
| INP (Interaction to Next Paint) | How quickly the page responds to clicks and taps | 200 ms or less |
| CLS (Cumulative Layout Shift) | How much the layout jumps around | 0.1 or less |
LCP: Loading Speed
LCP is the time it takes for the biggest item on the screen, often a hero image or heading, to appear.
How to improve it: compress images, use a CDN, enable caching, and use faster hosting.
INP: Responsiveness
INP checks how quickly your page reacts when someone taps a button or opens a menu.
How to improve it: reduce heavy JavaScript, remove unused scripts, and avoid long tasks that block the page.
CLS: Visual Stability
CLS measures annoying jumps, like a button moving just as you tap it.
How to improve it: set width and height on images, reserve space for ads and embeds, and avoid inserting content above existing content.
How to Check Your Scores
- Open PageSpeed Insights and enter your URL.
- Look at the real-user data if it is available.
- Check the Core Web Vitals report in Search Console.
- Fix the biggest issues first, then retest.
