How Can Web Developers Optimize For Google’s Core Web Vitals?

Why Google's Core Web Vitals Optimization Is Important for Websites?

The success of any website on the internet depends upon its optimization for the quality of user experience. And, to deliver that significant user experience, in 2020, Google announced its new metrics update that will be a part of the core ranking algorithm. These metrics got the name Core Web Vitals. According to Google, web pages must deliver exceptional user experience in terms of speed and usability perspective, and for that, they plan to introduce Core web vitals.

Google is developing and plans to roll out these metrics in May-June 2021, which means the time has come for the companies to consider this update and take necessary actions. A general thumb rule that is quite popular in the web development market is that web visitors lose interest if a web page takes a long time to load. This leads to an increase in the bounce rates of the users, and businesses lose their customers forever. If companies optimize their sites according to Google’s metrics, it helps them to retain their customers. It is a critical step for businesses looking to play a long game in the market.

So how web developers can optimize their websites with Google’s Core Web Vitals is a big question to discuss. This post will guide what core web vitals are and how they will help you optimize your business websites.

What are Core Web Vitals?

Google has always been providing several tools over the years to measure and monitor the sites’ performance. Like these practices, Core web vitals are the other initiative taken by Google to unify the websites’ quality.

Core web vitals are the subsets of Web Vitals that apply to all the web pages. It is a set of field metrics that measures and monitors the essential aspects of real-world user experience on the web. The metrics involved in Core Web Vitals have an associated threshold that gives the qualitative understanding to developers about the experience of their site that whether it is good, poor, or needs improvements.

As we know that Google pays a lot of attention to the on-page experiences, Web vitals play a significant role and add more value. So now, with keyword optimization, mobile-friendliness, safe browsing, HTTPS, and backlinks, Core Web vitals have become the next vital factor in determining the quality of the page experience on Google.

Moving on further, let’s discuss-

Core Web Vitals Metrics:

As a website owner, developer, or web development company, you must know about the critical metrics of Core web vitals.

#1 Largest Contentful Paint (LCP)

If the content takes a long time to render on a user’s screen, it leads to a poor user experience. Largest Contentful Paint is a core web vital used to measure the time a website takes to start displaying elements that are important to the user. LCP generally refers to the page loading performance of your website.

Google pays attention to it as it ultimately leads to an increase in the bounce rate of the sites. According to Google, the standard time for displaying elements of a website in the first frame is 2.5 seconds. If a website takes more time, it’s high time for businesses to take necessary actions.

In a nutshell,
Slow LCP = Low ranking & penalties
Fast LCP = Higher rankings and broad reach.

#2 First Input Delay

The responsiveness of your web page is the FID. First Input Delay refers to the interactivity of the users with the web page. This metric measures the time gap between the user’s first impression on the web page and the time browser takes to respond.

FID plays a vital role in measuring the user’s behaviour towards the web page. One of the common causes for poor FID is heavy JavaScript Execution. For speeding up the browser, it is essential to reduce the JS execution time.

#3 Cumulative Layout Shift

Cumulative Layout Shift is responsible for measuring the overall visual stability of the web pages. Have you ever noticed a web page full of buttons, ads, and videos, which keep pop-ups while reading something on the website? It is a result of poor on-page experience, and Google is strictly factoring in these issues. CLS sums up the scores across the layout shifts that don’t occur within 500ms of user input.

Removal of margins on featured images, dynamically injected content, lack of image specifications, on-page embeds, ads, and iframes with no dimensions are the common causes creating CLS issues. Make sure you implement robust CLS improvement strategies to get a score of 0.01. When your page scores are as close to zero, it ultimately makes your page better from less intrusive to better and interactive.

Now let’s talk about, How to improve Core Web Vitals?

#1 Image Optimization

Images have a significant influence on Core Web Vitals. If images of the websites take a long time to load, it ultimately affects your site’s performance. For better image optimization, you can go with the following best practices-

  • Optimize Image File Sizes

WebP is a modern format that delivers high-quality images at a smaller size. It is one of the popular formats used by Apple as well. Not only Apple but the upcoming release of Safari 14 on macOS and iOS are supporting WebP. Optimizing Images are considered one of the most powerful tools for improving Core Web Vitals; make sure you do it in the right way.

#2 JavaScript Optimization

Optimizing JS is another critical step for enhancing core web vitals as it impacts the loading of the websites. JS optimization in a correct way ultimately helps in speeding up the website’s loading time.

For better optimization, use google hosted JS, as it offers a range of standard libraries hosted on their servers that helps you with the fastest possible load times. Only send the code your users require and remove unnecessary ones.

Another critical factor to consider is removing the jQuery migrate module from the site as it incorporates several plugins and scripts that are no longer working. It ultimately affects the performance of the website. Perform an audit on your site to look whether such modules are available or not, and if it is present, then remove it as soon as possible.
