Eliminate Render-Blocking Resources
High Impact+2 points estimated
Why It Matters
Blocking JavaScript and CSS delay page rendering by 880ms, preventing users from seeing content quickly.
How to Fix
Move the 30KB JavaScript file (merged-4aa2f490edcbf1f5af5de30753912570-min.js) to load asynchronously using async or defer attributes. Inline critical CSS or use media queries to load non-critical CSS after initial render. Consider splitting large bundles into smaller chunks.

What This Score Means
A score of 94 falls in the "Good" 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
The arbas.at website has excellent performance with a score of 94/100, indicating fast loading times and good user experience. However, the biggest opportunity for improvement is fixing a redirect issue that's adding nearly 800ms of unnecessary delay when users visit the site - the URL automatically redirects from arbas.at to www.arbas.at, which slows down both First Contentful Paint and Largest Contentful Paint. Additionally, optimizing image delivery could save 118 KB of data transfer by properly sizing images for their display dimensions and improving compression. Addressing the redirect issue alone would provide the most significant performance boost, while the image optimizations would further enhance loading speed, especially on slower connections.
Other Optimization Recommendations
Fix Redirects and Server Response
High Impact+3 points estimatedWhy It Matters:
Multiple redirects delay initial page load by 780ms, significantly impacting both LCP and FCP scores.
How to Fix:
Update all internal links to point directly to https://www.arbas.at/ instead of https://arbas.at/. Configure your server to serve the canonical URL directly without redirects. Optimize server response time through caching or CDN implementation.
Optimize Image Delivery and Sizing
Medium Impact+1 point estimatedWhy It Matters:
Oversized images waste 118KB of bandwidth and delay LCP by 150ms due to improper sizing.
How to Fix:
Implement responsive images using srcset for the hero image (currently 1200x439 but displayed at 412x151). Compress the video thumbnail image and serve appropriately sized versions. Add explicit width and height attributes to SVG images in the footer to prevent layout shifts.
