How to improve core web vitals in Prestashop store

In our previous blog, we have learned How we can Improve Core Web-Vitals for OpenCart Store. Let’s discuss this in the case of the Prestashop e-commerce store.

We have a clear measure for a user’s experience due to Google’s Web Vitals. When you combine Web Vitals with Performance, gives a clear picture of what the user is going through.

Core Web Vitals

These are the measures that characterize a web page’s speed, responsiveness, and visual stability. The state of your website will be shown by the score against each measure.

It’s very likely that if these metrics aren’t optimized, your website will send Google the wrong signals.

Components of Core Web Vitals –

  1. Largest Contentful Paint(LCP) :- The time it takes for the page’s largest element to load. It could be a photo, an H1 heading, or something else. 2.5 seconds or less is the optimum LCP score.
  2. Cumulative Layout Shift (CLS) :- The visual stability of the page is considered in the Cumulative Layout Shift (CLS) score. A CLS score of less than 0.1 is optimal.
  3. First Input Delay(FID) :- Any delay in responding to a user’s input once they engage with a web page is referred to as First Input Delay (FID). A perfect FID score is fewer than 100 milliseconds.

How to measure Core Web Vital score

There are many ways to test the score of the website, here, we will test the website via PageSpeed Insight.

This website does not meet the norms of Core web vitals score. As a result, we need to learn how to enhance the performance of the website in order to improve customer experience.

How to Improve Core Web Vitals

Here are some basic recommendations to help you increase the speed of your website after you know your score:

Speed up your website

For a long time, site speed has been a ranking criterion. It’s critical that you work on it as part of your Core Web Vitals plan now that it’s under “page experience.”

Here are some things you can do to improve site speed:

  1. Use a Cache Module – The main reason why caching is important is that it reduces the load on your web server which ultimately reduces your users’ loading time.
  2. Invest in a CDN – Your static files will be cache across a content delivery network’s global network of edge servers.
  3. Use Gzip – Gzip is a file compression method that allows your server to provide smaller, faster-loading files or images to your website visitors.

Use Same Screen Format

Some layout adjustments can be prevented, but not all of them. Unless you prepare sites for different screen formats, this can be a problem to optimize your store for mobile.

The goal is to make your pages look the same on all devices (both desktop and mobile). Your Cumulative Layout Shift score will improve as a result of this.

Use Optimized media and images

Images must be displayed in online stores. However, having a lot of high-quality images (and videos) can slow things down and put you at a disadvantage in terms of ranking.

It’s essential that your images work well on mobile devices. This entails making them smaller in width.

This can be accomplished with the use of plugins such as Prestashop Google webP Image Converter.

Avoid excess Plugins

Even if extensions are beneficial for adding functionality to your website, only utilize the ones you absolutely need because having too many active plug-ins will slow down the site’s performance.

Secure Surfing

One of the UX signals that can help improve SEO grading is keeping a website clean. Check for malicious or deceptive content, as well as potentially dangerous links.

Without the reader’s knowledge, some malware on your site can redirect traffic to spam or malicious sites.

New Web Vital Score

We increased the website’s performance score after implementing all of the above ideas, and as a result, we enhanced the core web vital score.


Google’s latest page experience improvement in Core Web Vitals is a mechanism for the company to distinguish between low-performing and high-quality pages.

Any page that does not satisfy the necessary criteria will be lowered in Google’s search results as a result of the upgrade.

The LCP, CLS, and FID scores of a page will be used by Google to determine its worth.
