Understanding Core Web Vitals: The Analytic You Can't Ignore



At Sixtwo we are a team dedicated to living and breathing the web industry and bringing you the latest updates in bite size chunks

One of the latest additions to the digital toolkit is Core Web Vitals (CWV). If you’re not familiar with this term yet, don’t worry – we’re here to break it down for you.


What Are Core Web Vitals?
Core Web Vitals (CWV) are a set of specific factors that Google considers essential for user experience (UX). They focus on aspects such as loading performance, interactivity, and visual stability of a web page. These metrics aim to quantify the overall experience a user has when interacting with a website.

Google introduced CWVs in May 2020. This initiative came as part of their ongoing efforts to prioritise UX in search rankings. By incorporating these metrics, Google aims to encourage website owners to optimise their sites for better performance and usability.

Why Were They Introduced?

The introduction of CWV reflects Google’s commitment to delivering high quality search results to users. In an increasingly competitive online environment, UX plays a significant role in determining the success of a website. By emphasising factors like page speed and responsiveness, Google aims to ensure that users have a positive experience when accessing content through its search engine.

Core Web Vitals are important for several reasons:

SEO Ranking Factor: Google has officially confirmed that CWVs are now a ranking factor for search results. Websites that provide a better user experience, as measured by these metrics, are likely to rank higher in search engine results pages (SERPs).

User Experience: Improving CWVs directly correlates with enhancing the overall user experience. Faster loading times, smoother interactions, and fewer layout shifts contribute to a more enjoyable and satisfying browsing experience for visitors.

Competitive Advantage: Websites that prioritise CWV optimisation gain a competitive edge. By meeting or exceeding Google’s standards for user experience, they stand out among competitors and attract more traffic and engagement.

How to Check Core Web Vitals

Now that we understand the significance of CWVs, let’s explore how you can check them for your website. Google offers several tools for this purpose, including:

Google PageSpeed Insights: This tool provides a comprehensive analysis of your website’s performance, including CWV metrics. Simply enter your website’s URL, and it will generate a report with actionable insights and recommendations.

Google Search Console: The CWVreport in Google Search Console gives you a detailed overview of how your site performs in terms of loading, interactivity, and visual stability. It also highlights areas that need improvement and provides guidance on optimising your site.

Lighthouse: Lighthouse is an open source tool for auditing web pages. It assesses various aspects of performance, accessibility, and best practices, including CWVs. You can run Lighthouse tests directly from your browser or use it as part of Google’s PageSpeed Insights.

Is CWV the same as EEAT?

You might be asking what’s the difference between CWV and EEAT?

Core Web Vitals and EEAT are both crucial aspects of website optimisation and SEO, but they address different dimensions of performance and credibility. By prioritising both technical performance and content quality, website owners can enhance their visibility, credibility, and user satisfaction.

CWV focuses on technical performance metrics related to user experience, while EEAT encompasses broader considerations related to content quality and credibility.

CWV metrics are primarily quantitative and can be measured objectively using tools like Google PageSpeed Insights or Lighthouse. EEAT factors are more qualitative and may require manual evaluation of content and website reputation.

While both CWV and EEAT are important for SEO, they have different impacts on search engine rankings. CWV directly influences rankings by signaling to search engines the quality of user experience, while EEAT indirectly influences rankings by establishing trust and credibility.


By regularly monitoring and optimising your website’s CWV, you can ensure that it delivers a superior UX and maintains a strong presence in search results.

CWV represents a significant shift in how websites are evaluated for performance and UX. By understanding these metrics and taking proactive steps to improve them, web developers and marketers can enhance their online presence, attract more visitors, and achieve better rankings in search engine results. Embracing CWV isn’t just about meeting Google’s standards it’s about prioritising the needs and expectations of your audience.
