What Are Core Web Vitals and why are Core Web Vitals Important?

What are Core Web Vitals

The Core Web Vitals are a collection of particular factors Google considers crucial to the overall user experience of a website. The Core Web Vitals consist of three specific speed measurements and measures of user interaction most content-rich paint first input delay and the cumulative layout shift.

In the simplest terms, Core Web Vitals are one of the elements which will form part of Google’s “page experience” score (basically Google’s way of measuring the overall UX for your website).

It has three Core Web Vitals metrics:

  1. Largest Contentful Painting (LCP)is a measure of how quickly the biggest element (images video, animations, or text.) will load and show up on a web page.
  2. Cumulative Layout Shift (CLS)assures that websites’ pages aren’t cluttered with confusing, unexpected actions that could distract viewers from taking in the information.
  3. The First Input Delay (FID)measures the responsiveness of a website’s pages are for users who interact with them for the first time. It also shows how quickly the website’s browser can deliver users the desired result.

Why Are Core Web Vitals Important?

Google is planning to transform the experience of a page to the authentic Google rank factor.

The experience on the page is a mix of elements that Google believes are important to the user experience, such as:

  • HTTPS
  • Mobile-friendliness
  • The absence of pop-ups with interstitials
  • “Safe-browsing” (basically, not getting malware on your website)
  • Additionally, Core Web Vitals will be an essential component of this.

Based on the announcement and the title in the title, it’s safe to declare that web-related vitals will comprise the majority of your score on-page experience.

It’s crucial to note that a high page experience score will not magically propel you to the top spot on Google. Google was quick to emphasize that page experience is only one of several (approximately 200) elements they employ to determine how a website ranks in the search results.

How Can You Improve Your Core Web Vitals Score

Core Web Vitals will become an important factor for ranking in May 2021 as part of the Page Experience Update. This means that although quality content remains over the rest, the technical aspect that is part of SEO will take on more weight.

If you’re looking to increase the quality of your Core Web Vitals score before then, take five steps to ensure that your website is up to date with this algorithm update:

  1. Reduce Javascript execution
  2. Implement the lazy loading
  3. Image compression and optimization
  4. Make sure that images are properly dimensioned and embeds
  5. Increase response time of servers
  6. Cut down on JavaScript (JS) execution

If your report indicates an FID score that is low it indicates that your website interacts with users for more than 300 milliseconds. It is recommended to reduce and improve your JS execution. This means that the time that passes between your browser’s execution JS code and your page will be less.

It’s also important to utilize the least memory you can. Why? If your site’s code calls your browser’s permission, the program creates the memory of the browser, and blocks the JavaScript, and may slow down the speed of your page.

According to Google One way to minimize the time spent on execution is a delay of unneeded JS.

  1. Implement the lazy loading

If you have images displayed on your website it’s essential to use lazy loading to ensure your site’s UX and its core web vitals score don’t be damaged. Lazy loading lets you load images in the exact time as users scroll through the page without compromising the speed of loading the site and getting your LCP score of the highest quality.

Other advantages of lazy loading are:

  • The performance of your website will be enhanced.
  • It will limit the bandwidth used.
  • It will improve your website’s SEO.
  • It keeps your users on your page and will reduce bounce rates.

Do you think lazy loading will help your website? According to HubSpot sources, it is suggested that when pages have a lot of images or animations (aka large elements) it is recommended that lazy loading be considered to be a must. There aren’t specific guidelines for how pages that use lazy loading must be implemented. Therefore, if your site’s LCP score is not great You should think about trying lazy loading and then compare outcomes before and after the implementation.

  1. Image compression and optimization

It’s pretty evident, don’t you think? For many websites, the most important element is images. Therefore, it is essential to optimize your images since it will make your site substantially lighter, thereby improving the speed of loading, LCP score, UX, and rankings in search engines.

You can decrease the overall size of the page by compressing images into tiny jpgs and improving the quality of your LCP results. You may be thinking compression of images will reduce the resolution or quality of the image. In reality, it is only apparent the difference when zooming into the image or if it is stored in the incorrect format. Always make sure to use the images in the format jpg for landscapes and png format for graphics. It is also possible to use newer formats such as JPEG 2000, JPEG XR, or WebP however we recommend doing some research before you use them.

Apart from compressing, a crucial factor is activating Content Delivery Network (CDN) for images. CDN is a collection of servers around the world that store your content. Because servers are located in various locations, your images are served more quickly by the closest server to the user.

  1. Make sure that images are properly dimensioned and embeds

CLS score that is greater than 0.1 is considered to be poor. Usually, this is due to elements such as ads, images, or embeds that don’t have dimensions within the CSS file. If you’re looking to increase the quality of your CLS score, the dimensions matter. It is crucial to set the right width and height can help the browser assign the proper amount of space within the webpage while the element is in the process of loading.

For instance, if the dimensions of an image aren’t the right size, it will appear later on a webpage. When a user is browsing their content could abruptly disappear because the image with the wrong dimensions could not load quickly enough. In this instance, the browser was unable to comprehend the size of the space required to display that particular image.

  1. Enhance the response time of your server

Google states: “The longer it takes a browser to receive content from the server, the longer it takes to render anything on the screen. A faster server response time directly improves every single page-load metric, including LCP.”

In the end, lengthy response times to server requests can adversely impact not just your SEO, but also your UX.

To determine the speed of response from your server, you can make use of the Time to First Byte (TTFB) that determines the time that a web browser can receive one byte from the page’s content.

Conclusion

Although Core Web Vitals will be available in the Core Web Vitals will roll in just over 3 months, you must be already working to improve these vitals. Since vitals reports are out, make use of the tools above and examine your website’s performance before and after you’ve fixed the mistakes.

Keep in mind that your website’s backend is in sync with the front therefore, you must optimize your backend to offer the best user experience in terms of speed of loading visual stability, as well as interactivity. Additionally, it will help to remember the search engine’s current search signals such as mobile-friendliness, safe-browsing HTTPS, intrusive interstitial rules.
