Why It Matters
Render-blocking CSS and JavaScript files are delaying First Contentful Paint by 2.4 seconds, creating a poor initial user experience.
How to Fix

AI Performance Analysis
This WordPress site has poor performance with a score of 55/100, indicating significant user experience issues. The biggest problem is an extremely slow Largest Contentful Paint of 15.9 seconds, primarily caused by massive amounts of unused JavaScript from Google Tag Manager and other tracking scripts that waste 276 KiB and delay page rendering by 450ms. The site is also loading enormous images (6.4 MB total), with one single image consuming nearly 3 MB, and suffering from render-blocking resources that delay initial page display by 2.4 seconds. Removing unused JavaScript, compressing images, and optimizing the loading sequence could dramatically improve the score by 30+ points and reduce loading times by over 10 seconds.
Other Optimization Recommendations
Remove Unused JavaScript Immediately
High Impact+15 points estimatedWhy It Matters:
276 KiB of unused JavaScript (primarily Google Analytics/GTM scripts) is delaying LCP by 450ms and blocking critical rendering.
How to Fix:
Use a plugin like WP Rocket or Flying Scripts to defer Google Analytics and GTM scripts until user interaction. Remove unused tracking code for AW-11412716294 if not needed. Consider switching to Google Analytics 4 with minimal implementation.
Implement Proper Font Loading
Medium Impact+5 points estimatedWhy It Matters:
Custom fonts are causing 50ms delay in First Contentful Paint due to missing font-display declarations.
How to Fix:
Add font-display: swap to your Google Fonts CSS in the Elementor settings. Preload the most critical font files (Hanken Grotesk) using WordPress wp_head action. Consider using font fallback metrics to reduce layout shift during font loading.
