Remove Unused JavaScript Code
High Impact+18 points estimated
Why It Matters
Over 300KB of unused JavaScript is loaded, adding 2.25 seconds to LCP and blocking page rendering.
How to Fix
Install WP Rocket or Asset CleanUp Pro to identify and defer unused scripts. Remove unnecessary React dependencies (75KB wasted in eltako.min.js). Split your main JavaScript bundle to load only critical functionality first, then lazy-load the rest.

AI Performance Analysis
This WordPress site has poor performance with a score of 56/100, indicating significant user experience issues. The biggest problem is a 6.6-second delay caused by page redirects, which severely impacts both First Contentful Paint (10.1s) and Largest Contentful Paint (12.9s) - both far exceeding Google's recommended thresholds. The site is also loading 300KB of unused JavaScript and suffers from inefficient caching with no cache lifetimes set for key resources like fonts and images. Fixing the redirect chain and implementing proper caching could immediately improve loading times by over 6 seconds, while optimizing JavaScript and images could provide additional performance gains of 2-3 seconds.
Other Optimization Recommendations
Fix Page Redirects Chain
High Impact+25 points estimatedWhy It Matters:
Page redirects are causing a massive 6.6 second delay to LCP and FCP, severely impacting performance.
How to Fix:
Configure your WordPress site to serve the correct language version directly without redirects. Update internal links to point to https://www.eltako.com/en/ instead of the German version. Use a redirect plugin like Redirection to audit and remove unnecessary redirects.
Implement Proper Image Optimization
High Impact+12 points estimatedWhy It Matters:
Product images are oversized and uncompressed, wasting 322KB and delaying LCP by 300ms.
How to Fix:
Install ShortPixel or Imagify to automatically convert images to WebP format. Use responsive images with proper sizing - your product image is 669x813 but displays at 146x177. Add fetchpriority='high' to the LCP image and implement lazy loading for below-fold images.
