Why It Matters

How to Fix
Update snoesje-v2 theme to batch DOM reads and writes separately. Replace geometric property queries (offsetWidth) with CSS transforms where possible. Update Swiper.js to latest version which has performance optimizations for layout calculations.

AI Performance Analysis
This WordPress site has good performance with a score of 84/100, but has room for improvement in user interactivity. The biggest issue is an extremely slow Time to Interactive of 10.5 seconds, meaning users have to wait that long before they can fully interact with the page. The main culprits are unused JavaScript from Google Analytics/Tag Manager (wasting 133 KB) and render-blocking scripts that delay the initial page load. Removing unused JavaScript, deferring non-critical scripts, and optimizing the loading sequence could significantly improve interactivity and push this site into the excellent performance range.
Other Optimization Recommendations
Optimize Google Tag Manager Scripts
High Impact+8 points estimatedWhy It Matters:
Unused JavaScript from GTM and Google Analytics is wasting 133 KiB and blocking the main thread for 490ms.
How to Fix:
Remove unused Google Analytics events and triggers in GTM dashboard. Use gtag4wp plugin's built-in optimization features to load GTM scripts asynchronously. Consider moving non-essential tracking to fire only after user interaction.
Eliminate Render-Blocking Resources
High Impact+6 points estimatedWhy It Matters:
Compliance GDPR plugin scripts are blocking initial render, delaying First Contentful Paint by 150ms.
How to Fix:
In WordPress admin, go to Complianz settings and enable 'Load cookie banner asynchronously'. Move the TCF stub script to load after critical content. Consider inlining critical CSS from cookieblocker.min.css directly in the theme.
