Fix Render Blocking CSS

High Impact+25 points estimated

Why It Matters

Render blocking CSS delays First Contentful Paint by 4.75 seconds, severely impacting user experience.

How to Fix

Defer non-critical CSS files using media='print' onload="this.media='all'" attribute. Inline critical above-the-fold CSS directly in the HTML head. Use WordPress plugins like WP Rocket or Autoptimize to automatically optimize CSS delivery.

AI Performance Analysis

This WordPress site has poor performance with a score of 60/100, indicating significant user experience issues. The biggest problem is extremely slow loading times, with the Largest Contentful Paint taking a devastating 24.2 seconds - far beyond acceptable limits. The primary culprits are render-blocking CSS and JavaScript files that delay initial page rendering by nearly 5 seconds, plus massive unused code from YouTube embeds and other scripts totaling over 500KB of wasted resources. Immediate fixes should focus on deferring non-critical CSS/JS, removing unused YouTube code, optimizing the 5MB total page size, and converting images to modern WebP format, which together could dramatically improve load times and boost the performance score by 30+ points.

Other Optimization Recommendations

Optimize Font Loading Strategy

High Impact+15 points estimated

Why It Matters:

Custom fonts are blocking rendering for 1.64 seconds and causing invisible text during page load.

How to Fix:

Add font-display: swap to all @font-face declarations for LINESeedSansTH fonts. Preload the most critical font variant using <link rel='preload' as='font' type='font/woff2' crossorigin>. Consider using system fonts as fallbacks with font metric overrides.

Reduce Unused JavaScript

High Impact+12 points estimated

Why It Matters:

541 KiB of unused JavaScript is delaying LCP by 2.85 seconds, primarily from YouTube embeds.

How to Fix:

Replace YouTube embeds with lite-youtube-embed or similar lightweight alternatives. Remove unused WordPress plugins and JavaScript libraries. Use code splitting to load only necessary scripts per page.
