What is Core Web vitals? 

Core Web vitals is a Google Initiative to provide unified guidance for quality signals that are essential for a better web browsing experience for the users.

Core Web vitals are guidelines for web pages that apply to site owners and each Core Web vital shows a measurable user experience

Google Core Web Vitals Focuses on the following three metrics 

  • Largest Contentful Paint Element (LCP) measures how quickly the page loads i.e Loading Time of Page
  • First Input Delay Element (FID) measures how soon one can interact with the page i.e Interactivity. 
  • Cumulative Layout Shift (CLS) measures how stable the page is as it loads and as the user is interacting with it. 

Page Experience Ranking Factors 

A combination of Core Web Vitals metrics and search signals are termed Page Experience ranking factors. 

Search Experience Signals Includes :

  • Mobile Friendliness
  • Safe Browsing
  • Compliance with Google Widelines

In short, Google Uses a page experience set of metrics for determining the search rankings. 

Always remember – Mobile and Desktop experiences are separated.

Tips to improve your Core Web Vitals

Having a website that loads quickly and smoothly is important for keeping visitors engaged.

Google has identified three key metrics, known as “core web vitals,” which are essential for measuring website performance.

Here are some tips for improving your site’s core web vitals:

1. Preload Key Resources to Speed up Visual Load Times

When you access a web page, your browser requests the HTML document from a server, parses it, and sends separate requests for any resources that are mentioned in the document. 

Loading these resources may take time and impact the LCP of your website. 

To overcome that you can preload the important resources ( like the banner image above the fold) so that the browser can retrieve them before the browser would otherwise find them.

To do this you can use this preload command in your HTML document. 

<link rel=”preload” as=”script” href=”critical.js”>

2. Implement Lazy loading

Website loading time is critical not just from the SEO point of view but from the UX/UI point of view too.

 If a website takes too much time to load, the visitor may leave the site. 

However, with limited resources, loading the content on the web page within milliseconds is not possible. 

Lazy loading solves this problem as it enables the website to load only the necessary content first, then wait for the user to request the rest of the page’s content.

The browser loads only a portion of the page content at a time, reducing its time to open a website.

3. Optimize and compress images

Images are one of the bulkiest content on any webpage and if not optimized can lead to slow loading speed. So to improve the vitals of your website, optimizing the images is crucial. 

To optimize your images for a  website, use lighter image formats. For example, JPG is better compressed and loads faster as compared to PNG. 

There are a few others, such as JPEG XR and WebP, although they aren’t supported by all browsers.

Additionally, compress your images while uploading them on the website to reduce loading time. 

To manually compress your images you can use

You can also use plugins on your WordPress site to automatically compress images. 

4. Improve your server response time for better Website Uptime

Server Response Time is the time between a client requesting a page in a browser and a server replying to that request. Ideally, this response time should not be more than 200 milliseconds.

Following below can helo you improve your server response time

A reliable hosting service that provides you with high-performance servers.

b. Using Content Delivery Network ( CDN)

A CDN is a geographically distributed collection of servers that work together to provide content as rapidly as possible.  

Slow web page load times are caused by a hosting server that is located far away from the target audience. By reducing the distance between your hosting servers and your visitors, you can improve your website loading speed. 

There are two options when it comes to a CDN, you can either use a Free CDN or invest in a paid service. 

Free CDN is good for small websites with low traffic. However, if you have a business website that receives a large volume of traffic from across the world, consider the paid services. 

Cloudflare is a CDN service provider which has free as well as paid plans

If you use GreenGeeks as your hosting platform, Cloudflare CDN will be integrated with it for free and you can enable it in a few simple steps. 

5. Resize the YouTube video you want to display
