    What Are Core Web Vitals?

    Core Web Vitals are a set of performance metrics introduced by Google to measure user experience on web pages. They focus on three key aspects:

    1. Largest Contentful Paint (LCP): Measures loading performance. Aim for LCP to occur within 2.5 seconds of the page starting to load.
    2. Interaction to Next Paint (INP): Measures interactivity. Aim for an INP of less than 200 milliseconds.
    3. Cumulative Layout Shift (CLS): Measures visual stability. Aim for a CLS score of less than 0.1.

    Why Are Core Web Vitals Important?

    Good Core Web Vitals are crucial for:

    • User Experience: Fast and stable pages reduce bounce rates and increase user engagement.
    • SEO: Google uses these metrics as part of its ranking algorithm. Better scores can lead to higher search rankings.

    Understanding the Core Web Vitals Report

    Google Search Console provides a Core Web Vitals report that categorises your URLs into three statuses:

    • Good
    • Need Improvement
    • Poor

    These statuses help you identify which pages need attention.

    Key Metrics Explained

    1. LCP (Largest Contentful Paint): This metric looks at how long it takes for the largest element on your page to load. A good LCP score is 2.5 seconds or less.
    2. INP (Interaction to Next Paint): This metric assesses the responsiveness of your page to user interactions like clicks and keyboard inputs. A good INP score is under 200 milliseconds.
    3. CLS (Cumulative Layout Shift): This metric measures how much your page elements shift unexpectedly while loading. A good CLS score is 0.1 or less.

    How to Fix Core Web Vitals Issues

    1. Improving LCP

      • Optimise Images: Compress and use next-gen formats like WebP.
      • Minimise CSS and JavaScript: Reduce file sizes and defer non-critical scripts.
      • Use a Content Delivery Network (CDN): This can speed up the delivery of your site’s content.
    2. Enhancing INP

      • Reduce JavaScript Execution Time: Optimise and defer long-running scripts.
      • Optimise Server Response Times: Ensure your server is fast and reliable.
      • Utilise Browser Caching: Store static files on users’ devices to speed up subsequent visits.
    3. Reducing CLS

      • Set Size Attributes for Images and Videos: Define width and height to prevent layout shifts.
      • Avoid Inserting Content Above Existing Content: This can cause unexpected shifts.
      • Use CSS Transformations: For animations and transitions, use CSS rather than JavaScript.

    Tools to Measure and Improve Core Web Vitals

    • PageSpeed Insights: Provides insights into how your site performs and offers suggestions for improvement.
    • Lighthouse: An open-source tool integrated into Chrome DevTools for performance auditing.
    • AMP Page Experience Guide: For AMP pages, it provides a comprehensive test of your page’s Core Web Vitals.

    Monitoring and Validating Fixes

    After implementing fixes, use Google Search Console to track improvements:

    1. Validate Fixes: Start a 28-day monitoring session to confirm if issues are resolved.
    2. Regular Monitoring: Continually check the Core Web Vitals report to catch and fix new issues promptly.

    Conclusion

    Optimising Core Web Vitals can seem daunting, but by breaking it down into manageable tasks and using the right tools, you can significantly improve your website’s performance. This not only enhances user experience but also boosts your SEO efforts, helping your site rank higher in search results. Focus on LCP, INP, and CLS, and follow the outlined steps to ensure your site provides a fast, responsive, and visually stable experience for your visitors.
