Remove Unused CSS and JavaScript
High Impact+25 points estimated
Why It Matters
Eliminating 18KB of unused CSS and 116KB of unused JavaScript can improve LCP by 650ms and reduce TTI by 7.9 seconds.
How to Fix
Remove the entire Font Awesome CSS file since 99.5% is unused - use only needed icons as SVGs instead. Optimize Google Analytics by switching to gtag with minimal tracking events. In Next.js, use dynamic imports for non-critical components and enable tree shaking in webpack config.

What This Score Means
A score of 68 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 Next.js website has poor performance with a score of 68/100, primarily due to extremely slow loading times that take nearly 8 seconds before users can fully interact with the page. The biggest issue is inefficient resource loading - the site is loading 116 KiB of unused JavaScript (mostly from Google Analytics), 18 KiB of unused CSS (particularly Font Awesome icons), and oversized images that are much larger than needed for display. The site would benefit most from removing unused code, optimizing image sizes to match their display dimensions, and implementing better caching strategies, which could collectively improve the performance score by 30+ points and dramatically enhance user experience.
Other Optimization Recommendations
Optimize Image Delivery and Sizing
High Impact+20 points estimatedWhy It Matters:
Oversized images waste 1,074KB and delay LCP by 300ms, especially the hero image taking 1.98 seconds to render.
How to Fix:
Replace the 1024x1044 PNG logo with properly sized WebP versions using Next.js Image component with responsive breakpoints. Implement proper srcSet for the hero image at media.truck-liftutbildning.se. Use next/image with priority={true} for above-the-fold images and optimize image compression settings.
Fix Render Blocking Resources
Medium Impact+12 points estimatedWhy It Matters:
CSS files are blocking initial page render by 320ms, directly impacting First Contentful Paint and user experience.
How to Fix:
Move critical CSS inline using Next.js styled-jsx or CSS-in-JS solutions for above-the-fold content. Defer Font Awesome loading using next/dynamic with ssr: false. Implement CSS code splitting by route using Next.js automatic code splitting features to load only necessary styles per page.
