Core Web Vitals are one of Google’s most important ranking signals. They measure how users experience your website in real life — especially speed, responsiveness, and visual stability. If your Core Web Vitals are poor, your rankings and conversions will suffer.
For UAE businesses and digital marketers, optimizing Core Web Vitals in 2025 is essential to stay competitive and rank higher on Google.
This guide explains what Core Web Vitals are, why they matter, and how to improve them.
🧠 What Are Core Web Vitals?
Core Web Vitals are a set of performance metrics introduced by Google to measure page experience.
They focus on three main factors:
- LCP – Largest Contentful Paint
- INP – Interaction to Next Paint (replaced FID)
- CLS – Cumulative Layout Shift
Together, these metrics tell Google how fast and stable your website feels to users.
⚡ 1. LCP (Largest Contentful Paint)
LCP measures how long it takes for the main content of a page to load.
Ideal LCP:
- Good: under 2.5 seconds
- Needs improvement: 2.5–4 seconds
- Poor: above 4 seconds
Common causes of poor LCP:
- Large images
- Slow server response
- Heavy CSS or JavaScript
- No caching
How to improve LCP:
- Compress images
- Use faster hosting
- Enable caching
- Use a CDN
- Remove unused CSS
🖱 2. INP (Interaction to Next Paint)
INP measures how quickly your website responds when a user interacts (clicks, taps, types).
Ideal INP:
- Good: under 200 ms
- Needs improvement: 200–500 ms
- Poor: above 500 ms
Causes of poor INP:
- Heavy JavaScript
- Too many scripts running
- Poor frontend optimization
How to improve INP:
- Reduce JavaScript execution
- Remove unnecessary plugins
- Use lightweight themes
- Optimize third-party scripts
📐 3. CLS (Cumulative Layout Shift)
CLS measures how much your page layout shifts while loading.
Ideal CLS:
- Good: under 0.1
- Needs improvement: 0.1–0.25
- Poor: above 0.25
Causes of high CLS:
- Images without dimensions
- Ads loading late
- Fonts loading slowly
- Dynamic content
How to improve CLS:
- Set image dimensions
- Reserve space for ads
- Use stable fonts
- Avoid layout-shifting animations
