what-are-core-web-vitals by Knowband

A group of specified elements known as Core Web Vitals is one that Google believes to be crucial to the general usability of a website. Below are the three measurements that makeup Core Web Vitals, which are metrics for page speed and user engagement.

  • Largest Contentful Paint (LCP)
  • First Input Delay (FID)
  • Cumulative Layout Shift (CLS)

Core Web Vitals, in essence, are a subset of elements that makeup Google’s “page experience” score. In addition, they serve as Google’s primary method of evaluating the entire user experience of your web page.

Core Web Vital in page experience score

Largest Contentful Paint (LCP)

The measure of a web page’s ability to load quickly is LCP. The largest visible picture or text block within the view is used to calculate scores.

First Input Delay (FID)

When a user interacts with a page for the first time, this time interval is used to gauge how interactive a page is. It measures how long it takes the browser to start processing event handlers in response to the user’s interaction.

Cumulative Layout Shift (CLS)

By analyzing layout changes, this analyses the visual stability of a webpage. When a visible element relocates itself from one rendered frame to the next, this is referred to as a layout shift. It is more like how mobile and desktop interfaces change.

How to Improve the Core Web Vitals?

How to Improve the Core Web Vitals

We have included some advice on how to optimize your site for the essential aspects of the page experience to help you make sure it’s ready for this transition.

Caching Solution

Your server will work less hard if you cache your content. It is unnecessary to load static HTML versions of your pages each time a visitor views your website because a caching tool stores them.

You may be able to take use of server-level caching depending on your web host. On some WordPress plans, for instance, DreamHost provides server-side caching. To raise your FID score, putting into practice a premium caching solution can be beneficial.

Reduce The Size of Your Pictures and Videos

We are all aware of how important videos and photos are to eCommerce sites. Your buyers want to learn as much as they can about your items.

Large graphics may seem good on computers and tablets, but they can drastically slow down your mobile site and have a detrimental influence on how your users interact with the page. Additionally, they significantly lower your Core Web Vitals ratings.

Choose the ideal picture sizes for your site in collaboration with your developer, then start using that standard throughout your website. After giving the largest photos priority, you might be able to use an image scaling plugin or you could need to perform individual page modifications.

Allow Images to Load Into a Specific Space

Allow Images to Load Into a Specific Space

Cumulative Layout Shift (CLS), the third Core Web Vitals statistic, examines how much the visual layout of a page moves as it loads. This is to gauge a user experience (UX) that we have all likely had:

When a user attempts to click a specific link, the website unexpectedly repositions itself, causing them to unintentionally click on another section of the page. Failure to reserve space for images and embedded resources to load into is one of the most frequent causes of a high CLS score and consequently bad UX.

Font Optimization of Website


Your website’s fonts, like its photos, can affect how quickly users can access it. This is because they demand that the font family, together with each variant of its weight combinations, be downloaded and loaded by the browser.

You can enhance the functionality of your website by optimizing the web fonts. Due to their reduced file sizes and quicker delivery, optimized web fonts are the reason for this.

Additionally, if a text element’s associated web font hasn’t yet loaded, a browser might not automatically render that text element. Fallback font usage, on the other hand, can result in layout changes that lower your CLS rating.

Being selective about the fonts you use on your website is something very important. As a result, you can be sure that only the fonts you require for the text will be downloaded.
