Remove Unused JavaScript Code
Medium Impact+12 points estimated
Why It Matters
97KB of unused JavaScript from Google Tag Manager and Yandex Metrika delays LCP by 600ms.
How to Fix
Audit tracking scripts and remove unused features in GTM configuration. Load Yandex Metrika asynchronously after page load. Consider using Partytown to move third-party scripts to web workers to avoid main thread blocking.

AI Performance Analysis
This website has poor performance with a score of 57/100, indicating significant user experience issues. The biggest problem is extremely oversized images that are consuming over 14MB of data and taking nearly 46 seconds to fully load the largest content element. Three main images are using outdated PNG/JPG formats instead of modern WebP, and they're dramatically larger than needed - for example, one image file is 1680x1680 pixels but only displays at 61x61 pixels on screen. Optimizing these images by converting to WebP format and properly sizing them could save over 5MB of data and reduce loading times by 8+ seconds, dramatically improving the user experience.
Other Optimization Recommendations
Optimize and Compress Images
High Impact+25 points estimatedWhy It Matters:
Images consume 5.5MB and delay LCP by 8.9 seconds, representing the biggest performance bottleneck.
How to Fix:
Convert all PNG images to WebP format for 60-80% size reduction. Resize images to match display dimensions (current images are 5-27x larger than needed). Implement responsive images using srcset attribute. Add explicit width/height attributes to prevent layout shifts.
Implement Proper Image Caching
High Impact+18 points estimatedWhy It Matters:
Zero cache lifetime on images wastes 13.8MB on repeat visits and delays LCP by 11 seconds.
How to Fix:
Configure server to set Cache-Control headers with 1-year expiration for images. Add versioning to image URLs for cache busting when needed. Use CDN like Cloudflare to serve images from edge locations globally.
