Remove Unused JavaScript Code

Medium Impact+10 points estimated

Why It Matters

45 KiB of unused JavaScript from your main theme file delays LCP by 300ms and wastes processing time.

How to Fix

Audit your theme's main.js file to remove unused jQuery components and legacy polyfills. Use Asset CleanUp Pro to conditionally load scripts only on pages that need them. Consider tree-shaking your JavaScript build process to eliminate dead code.

AI Performance Analysis

This WordPress site has fair performance with a score of 75/100, but faces significant speed challenges. The biggest issue is render-blocking CSS and JavaScript files that delay the First Contentful Paint by 2.3 seconds and keep users waiting 5.1 seconds before the page becomes fully interactive. Additionally, the site is wasting 722 KB on unoptimized images and loading 60 KB of unused CSS code. By deferring non-critical CSS/JavaScript, compressing and properly sizing images, and removing unused code, this site could easily achieve a score above 85 and provide a much faster user experience.

Other Optimization Recommendations

Eliminate Render-Blocking CSS Resources

High Impact+25 points estimated

Why It Matters:

CSS files are blocking initial page render by 2.29 seconds, severely delaying First Contentful Paint.

How to Fix:

Install WP Rocket or Autoptimize to inline critical CSS and defer non-critical styles. Remove unused CSS rules which account for 81% of your main stylesheet. Consider splitting your theme's CSS to load only what's needed above-the-fold.

Optimize Images for Web Performance

High Impact+15 points estimated

Why It Matters:

Unoptimized images waste 722 KiB of bandwidth and delay LCP by 150ms, especially the hero image carousel.

How to Fix:

Convert JPEG images to WebP format using ShortPixel or Smush plugins. Add fetchpriority='high' to the main hero image. Compress carousel images more aggressively and ensure proper responsive sizing to avoid downloading oversized images.
