The Role of Core Web Vitals in SEO: 15 Best Practices for Optimization

Created: Jan 31, 2025

Updated: Feb 07, 2025

Can you imagine the frustration of a user who is looking for a product online and clicks on a website that seems promising but ends up where the user only finds disappointment? Because of the website loading time, unexpected errors, glitches, and wrong pages loading, and after trying to scroll many times, nothing happens. What will be the next step? The person will immediately hit the back button and move to another site. 

Google knows how much user experience matters. That’s why it introduced Core Web Vitals. These metrics have been designed to measure your site's performance for real users, focusing on speed, interactivity, and stability. By fulfilling these criteria, you can attract more users and rank higher on search engines. 

This blog discusses the 15 best practices for optimization that will help you improve Google’s ranking of your website. We will also discuss how GO-Globe can help you enhance your online presence as a top SEO company in Dubai

Let’s first understand these metrics and why they are important for ranking higher on Google. 

Core Web Vitals

Core Web Vitals consists of three major performance metrics. These metrics evaluate how your website loads, responds and remains visually stable. These metrics include:

Largest Contentful Paint: How Quickly Your Site Loads

LCP measures how long the largest visible content (like a banner image or heading) takes to load. A good LCP score is under 2.5 seconds.

First Input Delay: How Fast Your Site Responds to Actions

First, Input Delay measures how your website responds to user interactions. For example, how soon it proceeds if a user clicks a button. The goal is to keep the response time under 100 milliseconds.

Cumulative Layout Shift: How Stable Your Page’s Layout Is

CLS measures how many elements on your page shift unexpectedly. For example, a button moving while you’re about to click it creates a bad user experience. Keep your CLS score below 0.1 for a stable design.

Now, you have come to know the three major indicators of performance. Let's discuss why these matter:

  • LCP (Loading Speed): If your largest element takes too long to load, users lose interest quickly. Fast-loading content is essential for keeping them engaged.
  • FID (Interactivity): A responsive website encourages users to explore further. A delay in response, even a small one, can frustrate visitors.
  • CLS (Visual Stability): A stable page layout creates a seamless experience. No one likes to click on something that will shift them to an unexpected page.

How Core Web Vitals Help Improving SEO

The ranking of your website on Google depends on how effectively it fulfils the performance criteria designed by the search engine. Those websites rank higher and meet criteria than those that do not. But why do these metrics matter so much?

  • Higher Rankings: Sites with strong key web metrics perform better in search engine results.
  • Better User Experience: Faster, smoother sites keep visitors engaged longer.
  • Lower Bounce Rates: A slow or unstable website causes visitors to leave. Improving essential web metrics can prevent this.
  • Increased Conversions: A positive user experience often leads to higher sales or sign-ups.
  • Better User Experience Site: Google’s focus on user experience means optimizing these metrics is no longer optional.

How Does Google Measure Core Web Vitals? 

Google uses several tools and reports to evaluate Core Website Vitals. These include:

  1. Real User Data from Chrome: Google collects real-world data from Chrome users. It evaluates how your website performs for actual visitors.
  2. Lab Testing Tools: Tools like Google Lighthouse simulate your site's performance under controlled conditions.
  3. Field Data in Google Search Console: This report shows how well your pages meet page load indicator thresholds based on real user visits.

By analyzing both lab and field data, Google determines how well your site meets user expectations.

How can you Improve Your Core Website Vitals?

Check out the following SEO best practices that you can use to enhance your Core Website Vitals while ranking higher on Google.

1) Compress Images to Decrease Loading Time:

Large image files slow your website down. Use tools like Colorcinch and TinyPNG or convert images to WebP format. Smaller files mean faster loading times.

2) Implement Lazy Loading for Images and Videos:

Lazy loading ensures media loads only when users scroll to it. This reduces the time it takes for your page to load initially.

3) Content Delivery Network for Quick Delivery:

By using the Content delivery network, you can distribute your website content across multiple servers globally. This ensures visitors access your site from the closest server quickly. 

4) Minify Your CSS, JavaScript, and HTML Files:

Minification removes unnecessary characters like spaces and comments in your code. This optimization improves your website’s speed.

5) Preload Essential Resources for Faster Access:

Preloading ensures critical resources, like fonts or images, are ready immediately. This helps reduce LCP scores.

6) Prioritize Above-the-Fold Content:

Load the content visible on the screen first. This keeps users engaged while the rest of the page loads.

7) Use Fonts Optimized for Web Performance:

Custom fonts can delay text rendering. Use the font-display: swap property so fallback fonts display while custom fonts load.

8) Enable Browser Caching for Faster Repeat Visits: 

Browser caching stores website data locally on a user’s device. This improves load times for returning visitors.

9) Reduce Your Server Response Time:

A slow server affects everything. Upgrade to a faster hosting plan or optimize your server for better performance.

10) Limit the Use of Third-Party Scripts: 

Too many third-party scripts, like tracking codes, can slow your site. Keep only what’s essential.

11) Minimize Redirects to Avoid Extra Loading Steps:

Redirects add unnecessary steps for users to reach a page. Streamline your links to improve speed.

12) Optimize for Mobile Devices:

AMP creates lightweight versions of your site. This makes it load faster for mobile users.

13) Regularly Test Your Site’s Performance:

Use tools like Google PageSpeed Insights to check your site usability scores. Regular testing helps identify and fix issues.

14) Ensure Your Site Is Fully Responsive:

Check that all elements of your website work properly across all devices, including mobiles, tablets, etc. 

15) Take Help from Professional SEO Experts:

If you find it hard to follow the process, you can hire professional SEO experts. They use SEO best practices that can help you meet Google’s standards effectively. All these strategies can help you rank higher while following Google's performance metrics.
