Why Core Web Vitals Matter for Your Website
Core Web Vitals are the set of metrics Google uses to measure user experience, covering loading performance, interactivity and visual stability. They include Largest Contentful Paint (LCP), First Input Delay (FID) and Cumulative Layout Shift (CLS), and getting them right helps a site both convert better and rank higher in Google search results. Here are practical ways to optimise Core Web Vitals:
- Minimise Largest Contentful Paint (LCP) by reducing the size of above-the-fold content, optimising images, and using a fast hosting provider.
- Improve First Input Delay (FID) by reducing JavaScript execution time, splitting up long tasks, and deferring non-critical JavaScript.
- Decrease Cumulative Layout Shift (CLS) by avoiding layout shifts caused by images without dimensions, font changes, and dynamic content.
- Use a framework or library that prioritises Core Web Vitals, such as Angular or Lighthouse.
- Monitor Core Web Vitals regularly and address any issues promptly.
- Consider using a CDN to distribute content globally and improve loading times.
- Use resource hints, such as preconnect, dns-prefetch, and preload, to speed up resource loading.
- Minimise third-party scripts, as they can negatively impact Core Web Vitals.
- Ensure that your website is properly optimised for mobile devices, as poor mobile performance can lead to poor Core Web Vitals scores.
- Continuously measure and monitor your website’s Core Web Vitals to identify and address any performance issues.
Why Core Web vitals are important?
Core Web Vitals are important for the following reasons:
- User Experience: Core Web Vitals directly measure the user experience on websites, including loading performance, interactivity, and visual stability. By improving these metrics, websites can provide a better user experience and retain more visitors.
- Search Engine Optimisation: Google considers Core Web Vitals as a ranking factor in its search results. Websites with better Core Web Vitals scores are likely to rank higher in search results, increasing their visibility and attracting more traffic.
- Mobile Optimisation: With the growing number of users accessing the web on mobile devices, Core Web Vitals are increasingly important for mobile optimisation. Poor performance on mobile devices can negatively impact Core Web Vitals scores and reduce visibility in search results.
- Conversion Rates: Websites with better Core Web Vitals scores are more likely to have higher conversion rates, as users are more likely to engage with and trust websites that provide a good user experience.
- Accessibility: Core Web Vitals also impact accessibility for users with disabilities, as poor performance and visual stability can make websites harder to use for these users.
Optimising Core Web Vitals can improve the user experience, increase visibility in search results, support mobile optimisation, increase conversion rates, and improve accessibility for users with disabilities.
