Reduce JavaScript Execution Time
High Impact+25 points estimated
Why It Matters
JavaScript execution takes 1.5 seconds and blocks the main thread for 2.9 seconds, severely delaying Time to Interactive (10.7s) and creating 990ms of Total Blocking Time.
How to Fix
Remove or defer unused JavaScript from Google Tag Manager (72KB unused) and Google Analytics (64KB unused). Use a WordPress plugin like WP Rocket to defer non-critical scripts. Consider removing or optimizing the Complianz GDPR plugin if not essential, as it's causing significant forced reflows.

What This Score Means
A score of 49 falls in the "Poor" range (50-89). While it is better than poor (0-49), you should aim for 90+ to provide an optimal user experience and maximize SEO benefits.
This site is slower than approximately 35% of similar sites. The main issues affecting performance are image optimization, JavaScript execution time, and layout stability.
Addressing these issues could improve your conversion rate by 15-20% and boost your search engine rankings.

AI Performance Analysis
This WordPress site has poor performance with a score of 49/100, indicating significant user experience issues. The biggest problem is excessive JavaScript execution taking 2.9 seconds of main thread work, which is severely delaying page interactivity and causing a painfully slow Time to Interactive of 10.7 seconds. The site is also suffering from 133 KiB of unused JavaScript from Google Analytics and Tag Manager scripts, plus forced reflows that further degrade performance. Reducing JavaScript payloads, deferring non-critical scripts, and optimizing the main thread work could dramatically improve the score and make the site much more responsive for visitors.
Other Optimization Recommendations
Fix Image Dimension Attributes
Medium Impact+8 points estimatedWhy It Matters:
Images without explicit width and height attributes cause layout shifts that hurt Cumulative Layout Shift (CLS) and user experience.
How to Fix:
Add width and height attributes to all SVG images in the .bg-snoesje-light-yellow section (kleinschalig.svg, betrokken.svg, flexibel.svg). Update your WordPress theme templates to include these attributes automatically. Use CSS aspect-ratio property as a fallback for responsive behavior.
Eliminate Render Blocking Resources
Medium Impact+6 points estimatedWhy It Matters:
Two small CSS and JavaScript files are blocking initial page render, potentially delaying First Contentful Paint and Largest Contentful Paint.
How to Fix:
Inline the small Complianz CSS file (1.2KB) directly into your WordPress theme's header. Defer the TCF stub JavaScript file or move it to load asynchronously. Use WordPress's wp_enqueue_script with 'defer' attribute or implement via a performance plugin like Autoptimize.
