Optimize Product Image Delivery
High Impact+18 points estimated
Why It Matters
Product images are oversized and uncompressed, wasting 1,093 KiB and delaying LCP by 500ms.
How to Fix
Implement responsive images serving 154x154px versions instead of 400x400px originals. Convert all product images to WebP format for 75% smaller file sizes. Add proper caching headers to product images on cdn.hartmann.info (currently no cache). Use srcset with multiple image sizes for different viewport widths.

What This Score Means
A score of 43 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 website has poor performance with a score of 43/100, indicating significant issues that hurt user experience. The biggest problem is excessive JavaScript that's blocking the page from loading quickly - there's 726 KiB of unused JavaScript code that's delaying both First Contentful Paint (5.3s) and Largest Contentful Paint (9.5s) well beyond acceptable limits. The site is also serving oversized, unoptimized images that waste over 1 MB of bandwidth and lack proper caching. Removing unused JavaScript, optimizing images to modern formats like WebP, and adding explicit image dimensions would likely improve the performance score by 30+ points and dramatically reduce load times from nearly 10 seconds to under 3 seconds.
Other Optimization Recommendations
Eliminate Unused JavaScript Code
High Impact+25 points estimatedWhy It Matters:
726 KiB of unused JavaScript is delaying LCP by 1.8 seconds and blocking critical rendering.
How to Fix:
Audit chunk-vendors.js and bundle.js to remove unused dependencies. Split large bundles into smaller chunks loaded on-demand. Remove the entire 196KB icons-sprite.js file containing unused PayPal and logo SVGs. Use webpack-bundle-analyzer to identify and eliminate dead code.
Add Image Dimensions and Prioritization
Medium Impact+8 points estimatedWhy It Matters:
Missing image dimensions cause layout shifts and the LCP image lacks priority hints, delaying critical rendering.
How to Fix:
Add explicit width='350' height='234' attributes to all slider-img elements. Apply fetchpriority='high' to the hero banner image. Ensure the LCP image is discoverable in initial HTML without JavaScript. Remove lazy loading from above-the-fold images including the main banner.
