AI Performance Analysis

This WordPress site has poor performance with a score of 57/100, primarily due to excessive unused JavaScript that's slowing down page loading by over 1.6 seconds. The site takes nearly 12 seconds for the largest content to appear (LCP), which is critically slow for user experience. The biggest quick wins would be removing or deferring unused JavaScript from Google Analytics and chat widgets (saving 298 KiB), optimizing images to modern formats like WebP (saving 127 KiB), and adding preconnect hints to third-party services. These changes alone could improve the performance score by 30+ points and reduce loading times by several seconds.

Other Optimization Recommendations

Optimize Image Delivery and Format

High Impact+18 points estimated

Why It Matters:

Images can be reduced by 127 KiB, improving LCP by 350ms through better compression and modern formats.

How to Fix:

Install ShortPixel to automatically convert PNG images to WebP format (38-54 KiB savings per image). Resize the logo from 500x154 to 140x43 actual display size. Add fetchpriority='high' to the LCP element in your Divi theme template.

Fix Render Blocking Resources

High Impact+15 points estimated

Why It Matters:

Critical CSS and JavaScript files are blocking page render for nearly 2 seconds, severely impacting FCP.

How to Fix:

Move jQuery to footer through Divi theme options or using Code Snippets plugin. Inline critical CSS from et-divi-customizer-global.min.css above the fold. Use WP Rocket to defer jQuery migrate script loading until after page load.
