The Core Web Vital's Test: How to Pass It and Succeed Online

LCP Core Web Vitals Study
FID Core Web Vitals Study

A Study recently has revealed that less than 4% of websites passed the Core Web Vital’s test. Is yours one of them? Have you thought about using a web analytics tool for your website? If so, you’ve probably heard of the term “core web vitals.” The Core Web Vitals are an excellent indicator of user experience. Improving these metrics will improve the overall user experience of your website.

This post was written to help you understand core web vitals and apply them in your business. Websites with high Core Web Vitals (and associated Web Vitals) ratings perform better in Google searches.

About the Core Web Vitals Study -conducted by Searchmetrics

After crawling over 2 Million URLs – the groundbreaking data showed 96% of all websites did not achieve a good score in all 3 Core Web Vitals*.

This blew me away, as I had spent almost 5 months working on my clients and my own website getting ready for this GOOGLE roll out. What are people doing???

Aside from the three Core Web Vitals, the study examined 12 more relevant ranking indicators to provide more insight into which websites are performing well and where.

* Based on desktop data. Less than 10% of all mobile sites saw a good score in all three Core Web Vitals.
**This is based on the top 20 organic Google search results for three countries: the United States, the United Kingdom, and Germany.

What are Core Web Vitals CWV?

Core Web Vitals will officially become ranking variables in the Google Search algorithm in May 20212.

“Web Vitals is a Google endeavour to provide unified recommendations for quality signals that are critical to delivering a great web experience.” – 3Google

“In mid-June 2021, a gradual deployment will begin.” – 4Google

So, why is Google acting in this manner? This upgrade, according to Google, serves two purposes:

1. to place a greater emphasis on user experience at Google. In layman’s words, if a user has a positive experience on a website, Google will try to rank that page higher.

2. to make it easier for website owners and businesses to understand and enhance website performance.

However, this relatively little update has sparked considerable interest in the SEO and web development communities despite its apparent simplicity. It has raised several contentious issues, including

  • How should I interpret my Core Web Vitals results?
  • Do I need to make any changes to my website in preparation for this update? (let me say YES!!) If so, what is it?
  • How do competitors’ websites fare in terms of CWV? What goals should I set for myself? (opportunity to get ahead- with restructuring)
  • Are there any other ranking elements that are related to my Core Web Vitals score?
  • How simple is it to optimise websites built on builder/CMS platforms like WordPress or Wix? (Forget about WIX as I did)


Mobile and Desktop Performance: The best score for mobile web analytics is 7 (out of 7) or “excellent”, and it refers to a site that loads quickly on mobile browsers and the sites that load more efficiently on desktop browsers. The Core Web Vital’s score encompasses three metrics: mobile and desktop performance, as well as the “Largest Contentful Paint.” The scores are determined by A/B testing. 

Several factors determine mobile web performance. Mobile versus desktop web-enabled devices: Only the mobile website should be loading faster. Users who tend to use a mobile device to get their websites will get frustrated if their website is slow to load. These metrics also tends to affect mobile conversion rates.

The importance of Core Web Vitals Study

The Core Web Vitals have several parameters that should be checked. It includes the first input du to detect if the user can navigate through the website or is waiting for a specific page to load. It also includes the time to first action after page load. 

This is important because it indicates the loading speed of the website. Another factor that the test should include is the Largest Contentful Paint and the Last Input. These two factors are very important because they display if the users find the site to be effective. The result of the Core Web Vitals can then be used for planning and analysis, marketing and promotion and improvement of customer relations.

What are the core web vital metrics?

These statistics are based on the End User Test, Behavioural Testing, Audience Measurement, Largest Contentful Paint, and Interaction Test. 

The benefits of using web analytics tools provide quantitative analysis to compare the performance of websites. In addition, they provide statistics on data such as user interaction and demographics. Thus, helping you create your strategy to improve your website.


Core Web Vitals study was designed for Business Leaders.

While much of this research is technical in nature, it can point out areas where your team of web developers, UX designers, and SEOs require your assistance with focus and resources. In addition, it can provide concrete performance benchmarks that can be used as quality assurance targets.

The Core Web Vitals are a great predictor of user experience. Improving these indicators will improve your website’s overall user experience. If your team does not have the opportunity to focus on these Core Web Vitals measurements, your business may be jeopardised when Google introduces Core Web Vitals as ranking signals in mid-June of this year.

As a business leader, you may utilise the information in this study to support decisions to spend more resources or refocus your staff. These insights and benchmarks might help you decide where to concentrate your time and money on website development and SEO.

The major finding in this study relevant to leaders is that websites currently ranking well in Google tend to have better Core Web Vitals (and associated Web Vitals) ratings. We expect that this tendency will continue as Google places a greater emphasis on user experience.

Who Else Can Benefit from the Core Web Vitals Study?

  • This research was carried out for Marketers and Conversion Rate Optimizers.

Conversions are the ultimate goal of most marketing campaigns. However, the user experience can have a significant impact on the overall conversion rate. For example, slow loading landing pages frustrate users, resulting in a greater bounce rate.

Core Web Vitals are a quick and easy approach to measure user experience. They can be utilised to aid in creating more effective marketing strategies and the optimisation of conversions. This research provides CVW benchmarks so you can examine how you compare to the competitors.

Key Takeaway for Marketers and CROs: There is a lot of room for improvement in CVW scores. The majority of websites do not operate well. In your next marketing effort, emphasising user experience could provide you with a competitive advantage.

  • This study was carried out for those who work in SEOs.

This study is the most complete, data-driven analysis on Core Web Vitals that has been published to date, according to SEOs.

Crawling over 2 million URLs, examining the three Core Web Vitals data and 12 additional metrics and ranking variables to provide a complete view of web performance.

This study provides users with a view of how websites are doing ahead of the June Core Web Vitals update. Additionally, it can assist SEOs in understanding the Core Web Vitals environment and determining where chances for performance gains exist.

Important SEO Takeaway: The average performance of the bulk of websites crawled is lower than Google’s CVW criteria. While this may imply that Google will not penalise websites that fail Core Web Vitals performance on a large scale, it provides an excellent opportunity to increase rankings because outperforming other websites is currently a very realistic goal to attain.

  • Web Developers were the target audience for this study.

Web developers can gain an understanding of critical performance bottlenecks in terms of page loading time and interactivity. In addition, awareness of the impact that particular web design techniques may have on user experience allows web developers to understand better performance-limiting variables, which benefits the user and improves search engine performance.

Key Takeaway for Web Developers: While a web page should be visually pleasing, there is a fine line to walk between design and user experience. According to our findings, having too many plugins and render-blocking resources can lead to code bloat and substantially impair page performance.

How to measure your websites core web vitals.

Getting data is the easy part. Ensuring you have sufficient data to provide insights is another matter altogether. A study reveals that a staggering 99% of surveyed organisations have difficulties generating accurate, complete, and accurate stats. 

They then report these stats with scant detail. Core Web Vital’s Test Now, here’s the deal. You can’t just run a single core web vitals test on your website and be confident that it will provide insights. It would help if you had a large variety of tests to understand how your website performs. 

This is where Google PageSpeed Insights shines. Google PageSpeed Insights assists web designers in developing an optimal web structure based on speed considerations and user experience. It offers drag and drop tests and provides live analytics.

What is the source of your present low web performance?

Many websites are still failing to live up to their mobile-first promise. For example, we discovered that only the top 2-3 ranking websites often achieved a solid score in most Core Web Vitals indicators. This would imply that many websites still have work to do in terms of user experience. But why is this the case?

  • Website Development Technology

One issue is that website creation systems like WordPress and Wix have yet to catch up with customer expectations. While website builders like WIX and Squarespace appear to be simple to use, they might be difficult to optimise under the hood. (If you have a few hours, ask me about my WIX experience.)

Web pages created using these templates frequently load all scripts, stylesheets, and code blocks, even if they are not required. This might result in code bloat, which occurs when unnecessary code is loaded on a webpage, resulting in poor page loading speeds.

  • Plugin-heavy

A platform’s logic, such as WordPress’s, is also plugin-centric. This implies that if you need to do anything other than add basic content, such as optimising pictures or lazy loading below-the-fold material, you’ll need to instal a plugin. These plugins are quick fixes, but they frequently introduce extra code to your website that might be difficult to optimise.

  • Dynamic Content shifts and Ad Space

Dynamic content is another major source of poor user experience. Ads, for example, might create a lot of layout shifts if not correctly implemented. The same may be said for newsletter opt-in boxes and other dynamic content.

How to improve your Core Web Vitals

You’re the CEO of a start-up, and you want to build a robust website with huge web traffic. You feel overwhelmed. You’ve done your research on what other websites like yours are doing right. But all your ideas aren’t working. How can you improve the score of your website and achieve the seemingly impossible?

What gives you hope? What can you do to turn your website into a massive success? Core web vitals can help you by offering you indicators of how you compare with your peers. But, of course, the purpose of your efforts is to reach page 1 in ranking, right!

The best way to do this is by analysing your site’s performance and working on its fundamentals. How you can use Core Web Vitals, The Core Web Vitals can be accessed in the form of an analytical report.

Many tools, such as the Chrome User Experience Report, PageSpeed Insights, Search Console (Core Web Vitals report), and the Lighthouse Audit6, are available to assist you in measuring your Core Web Vital scores.

The easiest to use is Google Search Console (CWV report) – take a look at it and see how you are currently sitting. For example, are you in the 4% group or the 96% group?

It is a long fact that a reader will be distracted by the readable content when looking at its layout. 

Solutions for you to consider in improving your CWV

  • Code Bloat is slowing down your website; deleting unneeded CSS and JavaScript can improve load time.
  • Image Optimisation – Using a WP plugin to optimise your photos might save your site important loading time.
  • Your site contains YouTube videos rather than your own CDN storage for all videos hosted on your site. Youtube increases the time it takes for your page to load.
  • Web design should lose weight – i.e. look at a lower weight class
    Best Case Scenario: Wikipedia prefers a minimalist approach to site design, relying primarily on text and optimised graphics. As a result, the online encyclopaedia scores poor in LCP across numerous web pages, with an average entry taking 0.4-0.6 seconds.
  • Remove too many layout changes – The most common sources of layout shifts are media pop-outs, such as “subscribe now” boxes or advertisements. Websites that do not support dynamic content in their layouts fare poorly in terms of CLS.
  • Maintaining a limited number of server requests and small transfer sizes.
  • Avoiding large network payloads by limiting page size

Key Takeaway’s – Core Web Vitals Study

According to our findings, the highest-ranking websites have a performance edge in Core Web Vitals scores.

Even though Google has not yet incorporated Core Web Vitals into its core algorithm, websites that do well in these metrics tend to provide a favourable user experience.

There are, however, exceptions. For example, when prominent websites like YouTube are excluded, the data demonstrate that Google is willing to “ignore” bad user experience metrics as long as enough visitors continue to visit those websites.

In YouTube, practically all loading and engagement measures showed that the website performed pretty poorly. This raises the intriguing possibility that a Google-owned firm may fail most of the Core Web Vitals tests.

Understanding these indicators allows you to incorporate performance benchmarks into the web design process. For example, using Core Web Vitals can quickly determine whether your website provides a decent user experience. 

They are an excellent diagnostic tool for determining where performance benefits can be made, from image optimisation to removing unneeded JS or CSS code. This feedback can assist in guiding the web design process in a user-centric manner.
