Core Web Vitals Optimization for NWDS

To establish my expertise and trustworthiness, my strategy focused on a meticulous, data-driven approach. I developed and executed a multi-point plan targeting each key performance indicator.

• LCP & Page Speed Optimization:

  • I began by optimizing all critical images, converting them to modern formats like WebP where possible and compressing them to a fraction of their original size without visual quality loss.

  • I then implemented lazy loading for all images outside the initial viewport, ensuring only essential content was loaded immediately.

  • To address server-side latency, I worked with the hosting provider to improve Time to First Byte (TTFB), resulting in a faster response from the server.

• INP & Interactivity Improvements:

  • I performed a deep audit of the JavaScript on the page. I identified and minified render-blocking scripts, and deferred the loading of non-critical JavaScript to prevent it from delaying the main thread.

  • I also implemented a more efficient event listener strategy to improve the speed of user interactions.

• CLS & Visual Stability:

  • To eliminate all layout shifts, I manually added width and height attributes to all image tags.

  • I also preloaded critical web fonts and reserved space for dynamic elements to ensure the layout was stable from the moment the page began to render.
