The Impact of Core Web Vitals on SEO: What You Need to Know

While high-quality content and relevant keywords remain essential, Google’s focus on user experience has introduced a new set of ranking factors: Core Web Vitals. Here at CreativeFolks, we’re a data-driven SEO agency passionate about helping businesses optimise their websites for search success.  In this article, we’ll delve into the impact of Core Web Vitals on SEO, explaining what they are and how they can influence your website’s ranking.

Web Core Vitals

What are Core Web Vitals?

Core Web Vitals are a set of three specific metrics that Google uses to measure the real-world user experience of a web page. They focus on loading speed, interactivity, and visual stability – all crucial aspects of a positive user experience.

Here’s a breakdown of the three core metrics:

Largest Contentful Paint (LCP)

This metric measures the time it takes for the largest content element on your webpage to load. Ideally, your LCP should be within 2.5 seconds for a good user experience.

First Input Delay (FID)

This metric focuses on how responsive your website feels to user interaction. A low FID (ideally less than 100 milliseconds) indicates a website that feels smooth and responsive when users click, type, or navigate.

Cumulative Layout Shift (CLS)

This metric measures the visual stability of your content. A low CLS (ideally less than 0.1) signifies that your webpage elements don’t unexpectedly shift around after initially loading, preventing user frustration.

Why are Core Web Vitals Important for SEO?

While not the sole ranking factor, Core Web Vitals play a significant role in Google’s search engine ranking algorithm (SERP).  Here’s why they matter:

  • User-Centric Focus: Google prioritises websites that deliver a positive user experience. A website with slow loading times, lagging responsiveness, or unexpected layout shifts is likely to be penalised in search results.

  • Improved Engagement and Conversions: Fast, smooth, and visually stable websites naturally lead to better user engagement. When users have a positive experience, they’re more likely to stay on your website, explore your content, and convert into paying customers.

  • Correlation with Mobile-Friendliness: Core Web Vitals are inherently mobile-friendly, aligning with Google’s emphasis on mobile-first indexing. Optimising your website for these metrics improves its performance on all devices.

How to Optimise Your Website for Core Web Vitals?

There are several steps you can take to optimise your website for Core Web Vitals and improve your SEO performance:

Reduce Third-Party Scripts

Minimise image file sizes without compromising quality. Utilise lazy loading to prioritise loading content above the fold.

Optimise Images

Minimise the number of third-party scripts loading on your website, as they can slow down page load times.

Leverage Browser Caching

Enable browser caching to allow users’ browsers to store frequently accessed resources, reducing load times on subsequent visits.

Minify Code

Minify your website’s HTML, CSS, and JavaScript code to remove unnecessary characters and improve loading speed.

Utilise a Content Delivery Network (CDN)

A CDN distributes your website’s content across geographically dispersed servers, ensuring faster loading times for users worldwide.
