Reduce Unused JavaScript and CSS

High Impact+20 points estimated

Why It Matters

478 KiB of unused JavaScript and 216 KiB of unused CSS are blocking rendering and delaying page load by 900ms.

How to Fix

Use Asset CleanUp Pro plugin to disable unused scripts like Google AdSense and Plyr.js on pages that don't need them. Remove unused Bootstrap CSS classes and FontAwesome icons. Configure Autoptimize plugin to inline critical CSS and defer non-critical stylesheets to improve First Contentful Paint.

AI Performance Analysis

This WordPress site has poor performance with a score of 55/100, indicating significant loading issues that hurt user experience. The biggest problem is extremely slow content loading - your page takes 6.2 seconds for the largest content to appear and 9.5 seconds for the page to visually populate, which is far beyond acceptable standards. The main culprits are oversized images (wasting 1,175 KiB), excessive unused CSS and JavaScript (694 KiB combined), and render-blocking resources that delay initial page display by 3.6 seconds. Quick wins include compressing and properly sizing images, removing unused code, and implementing efficient caching, which together could improve your performance score by 30+ points and dramatically speed up your site.

Other Optimization Recommendations

Optimize Image Delivery and Caching

High Impact+25 points estimated

Why It Matters:

Images waste 1,175 KiB and delay LCP by 550ms while poor caching forces re-downloads of 2,174 KiB resources.

How to Fix:

Install ShortPixel or Imagify plugin to convert images to WebP/AVIF format and compress them. Configure WordPress caching plugin like W3 Total Cache to set proper cache headers for images (1 year minimum). Implement responsive images with proper srcset attributes to serve correctly sized images for different screen sizes.

Fix Font Loading and Layout Shifts

Medium Impact+12 points estimated

Why It Matters:

Font loading delays text visibility by 240ms and missing image dimensions cause layout shifts hurting user experience.

How to Fix:

Add font-display: swap to all @font-face declarations in your theme's CSS to show text immediately with fallback fonts. Set explicit width and height attributes on all images, especially the 366x250px advertisement banner. Preload critical fonts like Poppins and FontAwesome using <link rel='preload'> in your WordPress theme's header.php.
