Reduce JavaScript Execution Time
High Impact+20 points estimated
Why It Matters
JavaScript is consuming 3.6 seconds of execution time and blocking user interactions with 1.53 seconds of TBT.
How to Fix
Remove or replace the heavy jQuery 1.11.1 library with a modern lightweight alternative. Audit the Payrexx payment integration for unused code - consider lazy loading it only when needed. Use a plugin like Asset CleanUp to disable unused JavaScript on pages that don't need payment functionality.

What This Score Means
A score of 55 falls in the "Needs Improvement" 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 55/100. The biggest problem is excessive JavaScript execution time (3.6 seconds) combined with render-blocking resources that delay page loading by over 1 second. The site takes an alarming 58 seconds to become fully interactive, largely due to nearly 4MB of unused JavaScript from cookie consent and payment processing scripts. Implementing proper caching (which could save 7MB), minifying and removing unused JavaScript, and deferring non-critical scripts would dramatically improve loading times and user experience.
Other Optimization Recommendations
Eliminate Render Blocking Resources
High Impact+25 points estimatedWhy It Matters:
JavaScript files are blocking initial page render and delaying LCP by 1.15 seconds.
How to Fix:
Move jQuery and theme JavaScript files to load asynchronously using async or defer attributes. In WordPress admin, go to your theme's functions.php and add wp_enqueue_script() with array('strategy' => 'defer'). Consider using a plugin like WP Rocket or Async JavaScript to automate this process.
Implement Efficient Browser Caching
Medium Impact+12 points estimatedWhy It Matters:
Poor caching is wasting 7.2MB of bandwidth and delaying repeat visits by 450ms.
How to Fix:
Add cache headers to your .htaccess file or use a WordPress caching plugin like W3 Total Cache. Set long cache lifetimes (1 year) for static assets like JavaScript and CSS files. Configure your CDN (CloudFront) to serve cached versions of the Payrexx JavaScript files instead of fetching them fresh each time.
