# Core Web Vitals Guide: What They Are & How to Fix Them

Core Web Vitals measure how fast and usable your website is. Google uses them as a ranking signal — and they directly impact user experience and conversions.

## What Are Core Web Vitals?

Core Web Vitals are three specific metrics Google uses to measure page experience:

-   **LCP (Largest Contentful Paint)** — How quickly the largest visible element loads. Target: under 2.5 seconds. 
-   **INP (Interaction to Next Paint)** — How responsive the page is to user interactions. Target: under 200 milliseconds. 
-   **CLS (Cumulative Layout Shift)** — How much the page layout shifts during loading. Target: under 0.1. 

These are part of our [technical SEO](/technical-seo) and [Google optimisation](/google-optimisation) services.

## Common Fixes for LCP

-   Optimise and compress images (WebP format, proper sizing) 
-   Reduce server response times (TTFB) 
-   Remove render-blocking JavaScript and CSS 
-   Implement proper caching headers 
-   Use a CDN for static assets 

## Common Fixes for INP and CLS

**INP improvements:**

-   Reduce JavaScript execution time 
-   Break up long tasks into smaller chunks 
-   Optimise event handlers and third-party scripts 

**CLS improvements:**

-   Set explicit width/height on images and embeds 
-   Reserve space for ads and dynamic content 
-   Avoid inserting content above existing content after load
