Implement Efficient Browser Caching

Medium Impact+5 points estimated

Why It Matters

Poor cache configuration wastes 26 KiB on repeat visits and slows return user experience.

How to Fix

Install W3 Total Cache or WP Rocket to set proper cache headers. Configure Cookiebot scripts to cache for at least 7 days instead of current 14 minutes. Add cache-control headers for static assets through your WordPress caching plugin or .htaccess file.

AI Performance Analysis

This WordPress site has good performance with a score of 90/100, but there's still room for improvement. The biggest issue is excessive unused JavaScript, particularly from Google Tag Manager and analytics scripts, which is wasting 347 KiB of data and delaying page interactivity by 310 milliseconds. The site takes 7.5 seconds to become fully interactive, which is slower than ideal, primarily due to these bloated tracking scripts. Cleaning up unused JavaScript code and optimizing the loading of analytics scripts could significantly improve the Time to Interactive and enhance the user experience.

Other Optimization Recommendations

Optimize Google Analytics and GTM

High Impact+8 points estimated

Why It Matters:

Unused JavaScript from tracking scripts delays LCP by 300ms and wastes 347 KiB.

How to Fix:

Install a plugin like WP Rocket or Perfmatters to defer Google Analytics and GTM until user interaction. Configure GTM to load only necessary tags and remove unused custom JavaScript. Consider switching to Google Analytics 4 with minimal tracking setup.

Remove Unused CSS and Fonts

Medium Impact+3 points estimated

Why It Matters:

Unused CSS rules waste 39 KiB and can delay initial rendering of above-the-fold content.

How to Fix:

Use Asset CleanUp Pro or Autoptimize to identify and remove unused CSS from your WordPress theme. Optimize the Geomanist font loading by preloading only used font weights and styles. Remove or minimize Cookiebot CSS that's 87% unused by customizing the consent banner styling.
