Remove Unused JavaScript Code

High Impact+18 points estimated

Why It Matters

109 KiB of unused JavaScript is delaying LCP by 600ms and blocking critical rendering.

How to Fix

Use Asset CleanUp Pro to disable Swiper and iubenda scripts on pages that don't need them. Split the vendor.js bundle to load only required components. Implement code splitting in your WordPress theme to defer non-critical JavaScript until after page load.

AI Performance Analysis

This WordPress site has poor performance with a score of 65/100, indicating significant user experience issues. The biggest problem is an extremely slow Largest Contentful Paint of 7.4 seconds, primarily caused by oversized images that are being served at much higher resolutions than needed for display. The site is also bloated with unused CSS (54 KiB) and JavaScript (109 KiB), particularly from third-party scripts like Iubenda cookie solutions and Swiper libraries that aren't fully utilized. Additionally, forced reflows from JavaScript are causing layout thrashing, and render-blocking CSS is delaying the initial page display by 150ms. Optimizing image sizes, removing unused code, and implementing proper resource loading strategies could easily improve the performance score by 20+ points and dramatically reduce load times.

High Impact+15 points estimated

Render-blocking CSS is delaying both FCP and LCP by 150ms, hurting user experience.

How to Fix:

Add preconnect link to bunny-wp-pullzone-4rlf5v9ikc.b-cdn.net in your WordPress header. Inline critical CSS for above-the-fold content using Critical CSS plugins. Defer non-critical CSS using loadCSS or WordPress theme optimization.

Eliminate JavaScript Forced Reflows

Medium Impact+8 points estimated

Why It Matters:

Forced reflows are causing 126ms of unnecessary layout recalculations that block user interactions.

How to Fix:

Update iubenda cookie solution to latest version or switch to a lighter alternative. Batch DOM reads/writes in your theme's JavaScript. Use CSS transforms instead of changing layout properties in vendor.js animations.
