Implement Proper Caching Headers
Medium Impact+8 points estimated
Why It Matters
Poor cache lifetime for Cookiebot scripts forces repeat downloads on return visits, delaying LCP by 450ms.
How to Fix
Configure your WordPress caching plugin (WP Rocket/W3 Total Cache) to set longer cache headers for third-party scripts. Add cache-control headers for static assets via .htaccess or CDN settings. Consider self-hosting frequently used third-party scripts like consent management.

AI Performance Analysis
This WordPress site has poor performance with a score of 62/100, indicating significant user experience issues. The biggest problem is an extremely slow Largest Contentful Paint of 9.2 seconds, which means visitors wait over 9 seconds to see the main content load. The site is weighed down by 295 KiB of unused JavaScript from Google tracking scripts, inefficient caching that wastes 35 KiB on repeat visits, and oversized images that are 34 KiB larger than necessary. Removing unused JavaScript, implementing proper caching for third-party scripts, and resizing images to match their display dimensions could improve the score by 30+ points and dramatically speed up the site.
Other Optimization Recommendations
Remove Unused JavaScript Code
High Impact+25 points estimatedWhy It Matters:
295 KiB of unused JavaScript is delaying LCP by 1.5 seconds and blocking page interactivity.
How to Fix:
Audit Google Tag Manager implementation to remove unused tracking codes. Use WP Asset CleanUp to disable unnecessary scripts per page. Configure Google Analytics to load asynchronously after page interaction rather than blocking initial render.
Optimize Image Sizing and Delivery
High Impact+15 points estimatedWhy It Matters:
Oversized header image wastes 34 KiB and delays LCP by 300ms with poor mobile experience.
How to Fix:
Install Smush or ShortPixel to automatically generate responsive image sizes. Configure WordPress to serve properly sized images using srcset attributes. Resize the mobile header image from 675x465 to match its 412x284 display dimensions.
