How To Improve Core Web Vitals for an eCommerce Website
September 23, 2021 Sanjay Dabhoya

Google’s next Page Experience update will incorporate Core Web Vitals (CWV) signals into the official ranking algorithm. Core Web Vitals is a series of measurements that evaluate how fast web pages load and become interactive and aesthetically stable for real users. When it comes to your eCommerce website, it is essential to ensure that all of your critical online vitals are operational. To achieve that, you should learn what vital web lives are and how they may help you – and how you can increase metrics on your website if they already do not perform correctly.


What are the Core Web Vitals?

Google takes into account many indicators or metrics that can be used to assess the performance of websites. The measurements are used to analyze the website’s speed, reactivity, and visual stability. All three elements, when combined, can improve the website’s User Experience and Web Performance, and thus these elements are collectively known as the Core Web Vitals. The three significant metrics that comprise the Core Web Vitals are as follows:

Google core web vitals

1. LCP or Largest Contentful Paint

The Largest Contentful Paint or LCP can be defined as the time or the duration of time that is generally taken up for loading the contents of a page. Generally, to consider, 2.5 seconds or less is the optimal time limit. The website must improve if the time is between 2.5 and 4 seconds, and anything less than 4 seconds is deemed bad performance. This would bore out the users, and they would ultimately leave the page.

2. First Input Delay-FID or LID

The time it takes for a webpage to become interactive is called First Input Delay or LID. The interaction time a webpage takes and the suggested time limit is 100 milliseconds. Improvement is necessary between 100 and 300 milliseconds, while performance below 300 milliseconds is regarded as unsatisfactory.

3. Cumulative Layout Shift or CLS

The unexpected shift in a webpage’s visual layout shift should preferably be less than 0.1. If it’s higher than 2.5, the site needs to be improved.

According to Google, these are the essential health indicators for a website, and thus, one of the fundamental ones. Website owners can use these metrics to assess their site’s performance and make improvements easily.


How vital is Core Web Vitals?

Google wants to make these essentials a vital ranking criterion for websites. It aspires to make these indicators indispensable in determining organic rankings for websites.

If you run a business, you might not find Google’s algorithm interesting enough to learn about. On the other hand, understanding the vitals will make a lot of sense if you own an internet business, a website, or a SaaS company.

That’s because you’re curious about how the new ranking methodology will affect the performance of your website. Along with these essentials, mobile-friendliness and website page performance are also important considerations.

The reality is that if you fall behind and do not upgrade your site to meet the new criteria, your rankings will suffer, and your competitors will rise to fill the void. As a result, providing visitors with a top-notch user experience is critical.

In other words, keep your website healthy if you want to be part of the organic ranks. It is reasonable to assume that the core crucial will account for most of the page experience or user experience.


How do we measure Core Web Vitals and enhance them?

For most users, the Google tools package is sufficient to measure the core web vital, whether they are minor or massive. Chrome User Experience Report collects anonymized user measurement data on essential subjects (Chrome UX Report/CrUX). This data correctly measures the performance of the site using Core Web Vital reports and PageSpeed Insights.

Taking a brief look at this:

  1. Use the new Core Web Vitals Report to find pages requiring attention in the Search Console.
  2. Use Chrome UX Report and Lighthouse-enabled PageSpeed Insights or PSI to find out where the problem is on the page once you have successfully identified the pages that need to be repaired. PSI is accessible via the Google Search Console. Users may also use PSI to enter URLs.
  3. Use Chrome DevTools or Lighthouse to measure Core Web Vitals and get recommendations on fixing issues. The Web Vitals Chrome plugin allows you to observe the desktop in real-time.
  4. Use the CrUX Dashboard or the newest Chrome UX Report API if you need a specific Core Web Vitals dashboard. To access lab data, you may also use the PSI API.
  5. The can also be used to track page performance. It guides you through the process by showing a series of code labs that can optimize using PSI data.

Why page performance matters?
Longer page load times have a severe effect on bounce rates. For example:

  • If page load time increases from 1 second to 3 seconds, bounce rate increases 32%
  • If page load time increases from 1 second to 6 seconds, bounce rate increases by 106%


How to enhance web core Vitals?

LCP or Largest Contentful Paint: LCP differs from other page speed indicators because it helps to identify the essential aspects affecting page speed.

As a result, it refers to the visibility and interaction quotient of your website. The LCP speed score can be used with PSI. It is based on real user behavior because of Chrome’s statistics.

On the other hand, the limitation of PSI is that it can only review one page at a time. Google Search Console is valid for a broad website overview.

How can LCP be improved?

  1. The non-required third-party scripts should be eliminated.
  2. Users can help to quickly load websites utilizing lazy loads, which means that images are only loaded when the user scrolls down the page.
  3. Web hosting can be upgraded to make loading faster.
  4. PSI recognizes page elements and slows down the loading time. As a result, remove web page components.
  5. CSS should be light for fast loading.

FID or First Input Delay: FID is when a user needs to interact with a web page. What happens when a visitor first reaches the landing page of the site?

You can choose items from a menu, click a link, enter an email address, etc. The site should therefore be clean and feature all the necessary parts for rapid engagement. Similarly, the FID score for a website is determined by its type. Although it is preferable for FID for less than 100 milliseconds, there are specific approaches to boost reading.

How can FID be improved?

  1. Minimization of JavaScript
  2. Delete non-essential third-party scripts.
  3. Use the cache of the browser.

CLS or Cumulative Layout Shift: The visual stability of a website’s CLS is assessed. It aims to reduce the number of shifts on one page. Users may become angry when they click on another element and end up with another because of layout changes.

Announcements, dynamically introduced material, dimensional visuals, improper web types, and others can lead to terrible CLS. Google has therefore emerged as a benchmark for websites that “pass” the Core Web Vitals examination.

Using a set size property for any media will help determine the web page’s graphics usage. Announcements should be confined to a specific region of the page and only appear on that side.

UI functionality has been added.



There must not be a challenging method for optimizing your eCommerce site, but you should spend some time exploring the many choices. Hopefully, our fast tutorial has shown which fundamental web vitalities are crucial, why they are significant, and how you may improve them for your eCommerce site.

More analytics will be offered as part of this suggested adjustment to help Google improve the user experience today and in the future. Customizing your website according to these metrics can enhance your user experience and boost your search engine rankings.
