Achieving a Perfect 100% Core Web Vitals Score: Our Success Story

Our website,, just hit a perfect 100% score on Core Web Vitals! 🌟 This is a huge milestone for us, reflecting our dedication to providing the best user experience. Before this, our score usually hovered between 95-99%, but we never quite reached that 100% mark on both mobile and desktop. Here’s how we did it and why it matters.

Our Journey to 100%

At WordCamp Europe 2023, I talked to some folks about why our score wasn’t showing up as 100% in the search console. There were several reasons given, but none quite satisfied me. Some suggested our hosting could be an issue, while others pointed to our site’s images or JavaScript. However, we knew our site inside out and felt these weren’t the main problems.
Our team decided to dig deeper. We looked at every aspect of our site’s performance and made continuous improvements. We focused on three main areas: Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS). These metrics are crucial for user experience and search rankings.

Key Improvements We Made

  1. Largest Contentful Paint (LCP):
    • We optimized images by using modern formats like WebP.
    • Implemented lazy loading to delay the loading of offscreen images.
    • Minimized CSS to speed up the rendering process.
  2. First Input Delay (FID):
    • Reduced JavaScript execution time by deferring non-essential scripts.
    • Used web workers to run scripts in the background.
    • Improved our server response times by optimizing backend processes.
  3. Cumulative Layout Shift (CLS):
    • Ensured images and ads had explicit size attributes to prevent layout shifts.
    • Added reserved space for dynamic content like banners.
    • Improved font loading practices to avoid shifts when fonts load.

The Impact of a 100% Score

Why does this matter? Because Core Web Vitals are crucial for measuring how users experience websites. These metrics directly affect how high-up sites appear in search results and how engaged users are. A perfect score means:

  • Better Search Rankings: Google rewards sites with good Core Web Vitals by placing them higher in search results.
  • Enhanced User Experience: Faster load times and smoother interactions make users stay longer and interact more.
  • Increased Conversions: A seamless user experience encourages visitors to act, whether signing up, buying a product, or contacting us.

Hitting that perfect 100% shows that optimizing for Core Web Vitals isn’t just a wish—it’s totally doable, and it pays off big time!
