Remove Unused JavaScript Code
High Impact+15 points estimated
Why It Matters
142 KiB of unused JavaScript delays LCP by 1.2 seconds and blocks critical page rendering.
How to Fix
Use Asset CleanUp Pro or WP Rocket to disable Google Tag Manager and tracking scripts on non-essential pages. Remove unused Cookiebot features or replace with a lighter consent solution. Defer Google Analytics loading until after page interaction using gtag's transport_type: 'beacon'.

AI Performance Analysis
This WordPress site has moderate performance issues with a score of 75/100, but has significant room for improvement. The biggest problem is an extremely slow Largest Contentful Paint of 6.4 seconds, which means visitors wait over 6 seconds to see the main content load. The site is loading 142 KB of unused JavaScript from Google Tag Manager and other scripts that could be removed or deferred, and has poor caching policies that waste 56 KB of data on repeat visits. Fixing the JavaScript bloat, implementing proper browser caching, and optimizing the oversized images could potentially improve the score by 15-20 points and dramatically speed up the user experience.
Other Optimization Recommendations
Implement Efficient Browser Caching
Medium Impact+8 points estimatedWhy It Matters:
Poor cache lifetimes waste 56 KiB on repeat visits and slow LCP by 600ms for returning users.
How to Fix:
Configure your WordPress hosting or use WP Rocket to set cache headers for external scripts. Add cache-control headers for Cookiebot (1 week), Clarity scripts (1 month), and Cloudflare analytics (1 month) via .htaccess or CDN settings.
Add Image Dimensions and Optimize
Medium Impact+5 points estimatedWhy It Matters:
Missing image dimensions cause layout shifts and oversized images waste 13 KiB unnecessarily.
How to Fix:
Add explicit width and height attributes to all Clutch logo images in your WordPress theme templates. Use WordPress's built-in image resizing or ShortPixel to serve properly sized images. Replace the 583x600 business icon with a 315x324 version for mobile displays.
