The Importance of Core Web Vitals for SEO
How to check Core Web Vitals on Google?
A handful of times each year, Google makes updates to its core algorithm. Google designs each update to optimise search experience, one step at a time. Such changes can dramatically impact the search engine results page (SERP). Especially the distribution of the all-important top 10 of Google.
Google announced Core Web Vitals on May 28, 2020. According to Google, they represent essential characteristics of website user experience. The perfect user experience is hard to define. Core Web Vitals are Google’s new effort. A set of standardised metrics that they use to measure user experience. You can use them to improve your user experience, and your Google results at the same time!
Core Web Vitals
is a set of standardised metrics from Google used to measure and improve user experience.
The concept of judging websites by what a user feels when interacting with them isn’t new. Before the update, Google was already using some page experience signals:
The existing signals couldn’t capture the aspects of UX that relate to web performance. However, Google has combined three new metrics with the current UX signals to a unified Page Experience.
These metrics are the Core Web Vitals, and they measure your website’s user experience. The three main factors Google is looking for are 1) Page loading performance. 2) Ease of interaction. 3) Visual stability (from the user’s perspective).

Each quantifies part of how users interact and engage with a website. The Core Web Vitals offer you exciting opportunities for a rankings boost. But only if you get them right.
It’s important to remember that these metrics don’t tell the whole story about the user experience. Still, each metric helps site owners find the issues that are holding back their site today. It also allows developers and SEO experts to troubleshoot.
User expectations rise to higher and higher standards, and most sites are not keeping up. Some do things right and continually invest in site performance, and some do not. The gulf between eCommerce owners is ever-widening. These updates are a clear hint to the whole digital community and online business owners in particular. It’s high time to put the user in the high seat.
A real-world example: Look at the PageSpeed Insights report on the Magento website Christian Louboutin. Christian Louboutin is a fashion designer selling high-end and ultra-high-end footwear. A single pair of shoes can cost up to $6,000. With prices this high, it’s not worth it to leave a single conversion on the table. You’d expect the site to be perfectly streamlined.
But as you can see below, the store performs poorly on all but one metric. On aggregate, the page experience does not pass the Core Web Vitals assessment.

Ironic for a high-ticket shop that could fix some of these issues for the cost of a few products. The poor experience Christian Louboutin is serving users turns them away. The shop is leaving multi-thousand-dollar conversions on the table every single day. Don’t let this be you.
A score of “Good” in three categories is required to pass Google’s Core Web Vitals tests: Loading speed, responsiveness, and visual stability.
If a page does not pass, it will not rank as well as the more user-friendly pages.
So, the big question is:
Original and relevant content will always be stellar for SEO. Yet Google will also evaluate website performance on other metrics. The news here are measurements of how well users interact with your website.
The weight of this change is initially small. However, it will likely increase over time. The change will occur gradually as more websites adopt Google’s best practices and Core Web Vitals.
Are search performance, brand awareness, and visibility important for your eCommerce store? Then, you should optimise your shop for the Core Web Vitals update. That way, you will stay ahead of the competition.
These updates should not ruin your site’s organic visibility if you are otherwise following SEO best practices. Google highlights that page experience is one among 200+ factors that they use to rank websites.
Well-written and relevant content is still crucial. But your website should provide an optimised user experience in addition to good web design and quality content.
Let’s look at the three primary metrics included in Core Web Vitals and how they may be relevant to your site today. Core Web Vitals focus on loading, interactivity, and visual stability. As expressed in quantitative metrics, here are the three current components.
Ask your developer if he is aware of these metrics. If not, there is further reading for technically savvy readers on web.dev.
The Core Web Vitals report comes in two segments, desktop and mobile.
The primary aim of the Core Web Vitals is to determine whether your site is usable for visitors. Thus, they influence your position in search results. They also indicate the weak points of your online store so you can fix them. Eliminating these problems will do two things at once. 1) Raise your online shop in SERPs. 2) Improve other critical metrics like bounce and conversion rates.
Largest Contentful Paint is a metric that site owners can use to assess user experience. It determines how quickly the page’s most significant piece of content appears on a mobile/desktop screen.
The largest element is typically the featured image or maybe the <h1> tag but it could be any of these:
Site owners should aim for an LCP below 2.5 seconds. The shorter the delay, the less attention is required by the visitor.
It’s frustrating for users when they try to click something on a page, but nothing happens.
FID expresses the time from when a user interacts with your page until the page responds – a type of responsiveness.
Example interactions include:
Not all users will interact with a page, so they may not have an FID value. Neither will tests with lab tools produce a value – they don’t interact with the page. So, use Total Blocking Time (TBT) instead.
Developers need to reduce the time users spend waiting for a browser to respond to their input. Low FID improves engagement and usability across the site.
Site owners should aim for FID below 100 milliseconds. This provides a satisfactory user experience, but shorter is better.
Have you ever clicked on a page that shifted, so you ended up clicking on something you didn’t intend? You were probably annoyed, but as a website owner, you may be more forgiving of mistakes. Ordinary users hate it.
Cumulative Layout Shift is a metric that identifies links or buttons that shift after a web page has loaded. The metric reflects the level of difficulty users will experience when trying to engage with elements on your site once the page renders. It takes into account both the size of the content and the distance it moves.
First, identify the pages with poor CLS. That will show you how to improve usability, drive click-through rates, and increase your overall conversion rate.
One major issue with the metric is that it continues to measure even after the initial page load. Google is taking feedback on this particular metric, so we’ll likely see some changes to it in the future.
Common causes of CLS include:
You should maintain a CLS of 0.1 or less. Ideally, sites shouldn’t shift at all. But if some of your pages include heavy elements, you may need to compromise between CLS, LCP and other metrics. A good developer will help you improve both. If necessary, they can also identify the exact balance where you will maximise your conversions.
There are also secondary metrics that affect how users experience content. Here are some of them. You can use them to understand the experience visitors have on your site:
Scores in each category indicate your performance. Ninety or above is satisfactory. 50-90 requires improvement. If you have a score below 50 (poor) in any category, you should contact your devs and have them fix it immediately.
The assessment of Core Web Vitals for any site is public knowledge. Google has published the essence of Core Web Vitals. In addition, they provide free tools to evaluate them. Finally, the tools give helpful advice on fixing the issues revealed.
There are a handful of ways to see if your page scores “poor”, “need improvement,” or “good”. You can use them to evaluate your website and get advice on how to make improvements.
