AI Performance Analysis
This WordPress site has decent performance with a score of 82/100, but there's significant room for improvement. The biggest issue is excessive unused JavaScript (313 KiB of waste) from Google Analytics and other scripts, combined with a slow Time to Interactive of 6.9 seconds that's hurting user experience. The site is also loading 21 KiB of unused CSS and has poor caching policies for Facebook tracking scripts. Cleaning up unused code, implementing better caching strategies, and deferring non-critical JavaScript could easily push this site into the 90+ performance range and dramatically improve loading speeds.
Other Optimization Recommendations
Remove Unused JavaScript Code
High Impact+12 points estimatedWhy It Matters:
313 KiB of unused JavaScript is blocking page interactivity and delaying Time to Interactive by over 3 seconds.
How to Fix:
Use WP Asset CleanUp plugin to disable unused scripts per page. Defer Google Analytics and GTM loading until after page load. Remove or replace the heavy Facebook Pixel implementation with a lighter alternative like PixelYourSite that loads asynchronously.
Implement Better Resource Caching
Medium Impact+8 points estimatedWhy It Matters:
Poor cache lifetimes for 144 KiB of resources force unnecessary re-downloads on repeat visits.
How to Fix:
Configure longer cache headers for Facebook Pixel and Google Analytics through your CDN or caching plugin. Set cache-control headers to at least 31536000 seconds (1 year) for static resources. Use WP Fastest Cache or W3 Total Cache to implement proper browser caching rules.
