AI Performance Analysis
This WordPress site has poor performance with a score of 44/100. The biggest problem is excessive JavaScript execution taking 5.8 seconds of main thread work, which severely delays page interactivity (22 seconds to become fully interactive). The site is loading 265 KiB of unused JavaScript from Google Tag Manager and other scripts, while also suffering from unoptimized images totaling nearly 7MB. Reducing JavaScript payloads, removing unused code, and compressing images to modern formats like WebP could improve the score by 30+ points and dramatically reduce load times from the current 21+ seconds.
Other Optimization Recommendations
Optimize Critical Image Delivery
High Impact+25 points estimatedWhy It Matters:
Large unoptimized images delay LCP by 21.3 seconds and consume 2.3MB of unnecessary bandwidth.
How to Fix:
Install ShortPixel or Imagify plugin to convert PNG images to WebP format for 60-80% size reduction. Enable responsive images in WordPress settings. Add fetchpriority='high' to your hero background video container to improve LCP discovery.
Implement Proper Image Dimensions
Medium Impact+8 points estimatedWhy It Matters:
Images without explicit dimensions cause layout shifts and prevent browser optimization during page load.
How to Fix:
Add width and height attributes to all carousel images in your Elementor Swiper slider. Use WordPress's built-in responsive image features. Set font-display: swap on FontAwesome and Elementor icon fonts to prevent invisible text.
