If you want your website to rank higher on Google, Core Web Vitals should be a top priority. Core Web Vitals are Google's page experience metrics that measure how users interact with your website. They help evaluate loading speed, responsiveness, and visual stability, making them an important part of Technical SEO.

A website that loads quickly and responds smoothly provides a better user experience, leading to higher engagement, lower bounce rates, and improved search engine rankings.

What Are Core Web Vitals?

Core Web Vitals are a set of website performance metrics introduced by Google to measure real-world user experience. These metrics help website owners understand how visitors experience their pages.

Google currently focuses on three important metrics:

1. Largest Contentful Paint (LCP)

Largest Contentful Paint (LCP) measures the loading speed of the main content on a webpage, ensuring visitors can view important information as quickly as possible.

Good Score: 2.5 seconds or less

A faster LCP means visitors can see your content quickly without waiting.

Ways to Improve LCP

Optimize images
Use modern image formats like WebP
Enable browser caching
Reduce server response time
Use a Content Delivery Network (CDN)
Minify CSS and JavaScript

2. Interaction to Next Paint (INP)

Interaction to Next Paint measures how quickly your website responds when users interact with it, such as clicking a button or opening a menu.

Good Score: 200 milliseconds or less

A fast INP creates a smooth browsing experience and improves user satisfaction.

Ways to Improve INP

Reduce JavaScript execution
Remove unused scripts
Optimize third-party plugins
Improve browser rendering
Split large JavaScript files

3. Cumulative Layout Shift (CLS)

CLS measures the visual stability of a webpage.

Unexpected layout shifts occur when buttons, images, or advertisements move while users are interacting with the page.

Good Score: 0.1 or less

Ways to Improve CLS

Set image dimensions
Reserve space for advertisements
Avoid inserting content above existing content
Load fonts properly
Reduce dynamic content shifts
