In the early days of SEO, the focus was straightforward: pack in keywords and gather as many links as possible.

Quality often took a backseat. But as technology and search algorithms evolved, so did a search engine optimisers priorities.

Search engines began valuing user experience, mobile-friendliness, and content relevance. SEO transformed from merely gaining visibility on search engines to genuinely serving the users.

Today, technological innovations like AI and automation are reshaping SEO. They streamline tasks from keyword research to website audits.

This ongoing evolution has paved the way for Google’s Core Web Vitals, emphasising the importance of a great user experience.

Diving into Google’s Core Web Vitals

Google’s commitment to offering the best user experience is evident. To uphold this mission, they’ve introduced Core Web Vitals. But what are these exactly?

At their essence, Core Web Vitals are a set of metrics. They’re designed to measure how users experience the speed, responsiveness, and visual stability of a page.

These aren’t just technical terms; they have real-world implications. For instance, if a website takes ages to load, or if elements keep shifting around, users get frustrated. This affects their overall experience and, possibly, their perception of the brand.

There are three main components to Core Web Vitals:

  1. Largest Contentful Paint (LCP): This metric focuses on loading performance. Ideally, the main content of a web page should load within 2.5 seconds from when the page first starts loading.
  2. First Input Delay (FID): This captures interactivity. It measures the time from when a user first interacts with a page (like clicking a link) to when the browser responds. For a good user experience, pages should have a FID of less than 100 milliseconds.
  3. Cumulative Layout Shift (CLS): The CLS metric measures how often users experience unexpected layout shifts on a page while it loads. A good experience means having a CLS score of less than 0.1.

By understanding and optimising for these metrics, businesses can enhance their online presence. More importantly, they ensure users have a seamless and enjoyable experience while browsing their website.

The Significance of Google’s Core Web Vitals

Google doesn’t introduce changes lightly. When they emphasise a new set of metrics, it’s a clear indicator of where the future of online search is headed. So, why are Core Web Vitals so significant?

Historically, SEO focused on content, keywords, and backlinks. While these are still essential, the user’s interaction and satisfaction with a site are now front and centre. Core Web Vitals quantify this experience, ensuring users don’t just visit a site, but enjoy their stay.

These metrics also directly influence search rankings. From 2021 onwards, Google started factoring in Core Web Vitals into its ranking algorithm.

Websites that don’t measure up in terms of LCP, FID, and CLS might find themselves slipping down search results. This makes it imperative for businesses to optimise their website, ensuring both a superior user experience and a prominent place in search results.

Lastly, they set a universal standard. With the introduction of these vitals, web developers and designers have clear benchmarks to aim for. This means a move towards a more consistent and high-quality web, benefitting both businesses and end-users.

Tools to Assess Your Website’s Performance

For webmasters and site owners, understanding where your site stands in terms of Core Web Vitals is crucial. Thankfully, there are several free tools available that can help assess and optimise your site’s performance.

Google’s PageSpeed Insights

PageSpeed Insights a free tool from Google that provides both mobile and desktop performance analysis. It gives an overview of your website’s loading speed and offers actionable recommendations to improve Core Web Vitals metrics.


GTmetrix analyses your website’s speed and provides comprehensive insights, including Core Web Vitals scores. The user-friendly interface makes it suitable for both beginners and experienced developers.

Chrome DevTools

Built into the Google Chrome browser, Chrome DevTools allows developers to test and debug their websites in real-time. The “Performance” tab is particularly helpful for analysing the different Core Web Vitals.

Remember, the goal isn’t merely to achieve passing scores on these tools. It’s about ensuring your website delivers an optimal user experience.

Using these tools to assess and update your website regularly can be the difference between a site that merely exists and one that thrives in the online world.

How to Improve Your Core Web Vitals

It’s crucial to take proactive measures to ensure your website meets and exceeds the Core Web Vitals benchmarks. Here are some effective ways to improve these metrics on your site:

Optimise Images

Large and unoptimised images can significantly slow down page loading times.

Compressing images, using modern formats like WebP, and implementing responsive images can make a substantial difference in your Largest Contentful Paint (LCP) score.

Reduce Server Response Times

Consider using a Content Delivery Network (CDN) to distribute your site’s content across multiple servers worldwide. This reduces the distance between the end user and the website server, speeding up content delivery.

Implement Lazy Loading

By only loading images and other resources when they’re visible to the user (as they scroll down), you can improve the initial load time and reduce the strain on the user’s device.

Minimise CSS and JavaScript

By removing unused code and minimising the remaining code, you can reduce the amount of data that needs to be processed, enhancing your First Input Delay (FID) and Cumulative Layout Shift (CLS) scores.

Prioritise Above-The-Fold Content

Ensure that content visible to users when they first land on your site loads as quickly as possible. This can be achieved by prioritising the loading of above-the-fold content and deferring the rest.

Avoid or Minimise Pop-ups

Unexpected layout shifts, often caused by pop-ups or dynamic content, can be detrimental to the user experience. Limit their usage or design them to be less intrusive to the page’s layout.

The Future of Google’s Core Web Vitals

Looking ahead at the next few years of Google’s Core Web Vitals, several crucial updates and changes are on the horizon that webmasters and SEO professionals need to be aware of.

Interaction to Next Paint (INP)

One of the most significant changes to Core Web Vitals is the upcoming transition from First Input Delay (FID) to Interaction to Next Paint (INP) in March 2024.

FID, which measures responsiveness, had its known limitations. Recognising this, the Chrome team initiated research to find a more effective metric.

After extensive feedback and testing, INP was announced in 2022 as the improved metric.

In March 2024, INP will officially replace FID, bringing a more comprehensive approach to measuring site responsiveness.

For a deeper understanding of this transition, the Chrome team’s blog post provides valuable insights into the rationale behind this new metric.

Focusing on Mobile Experience

With the rapid growth in mobile users online in recent years, ensuring a seamless mobile experience will continue growing in importance to Core Web Vitals and Google.

Sites will need to focus on mobile-first designs, optimise for touch interfaces, and address issues like tiny clickable elements or poorly sized content.

Improving Website Security

User trust plays a pivotal role in website engagement. With increasing threats online, sites that offer robust security features, including HTTPS and robust anti-phishing measures, will potentially see better Core Web Vitals scores as they contribute to an overall improved user experience.

Wrapping Up

Google Core Web Vitals serves as a compass, guiding webmasters towards creating sites that are user-friendly, mobile responsive, and fast.

With imminent changes like the shift from FID to INP and the ongoing need to adapt to emerging technologies, staying updated is crucial.

Embracing these changes and prioritising user experience will ensure that your website not only ranks better but also provides genuine value to their visitors.
