Remove Unused JavaScript Code
High Impact+20 points estimated
Why It Matters
575 KiB of unused JavaScript wastes bandwidth and increases LCP by 1.4 seconds.
How to Fix
Remove or replace heavy Kinescope video player scripts if not essential for above-the-fold content. Implement lazy loading for video players to load only when needed. Split Yandex Metrika tracking code to load asynchronously after page interactive. Use tree-shaking or code splitting to eliminate unused portions of remaining scripts.

AI Performance Analysis
This website has poor performance with a score of 56/100, indicating significant issues that need attention. The biggest problem is an extremely slow Time to Interactive of 14.2 seconds, caused primarily by 575 KiB of unused JavaScript from video player and analytics scripts that are blocking the page from becoming fully interactive. The site also suffers from render-blocking resources that delay the First Contentful Paint (3.2s) and Largest Contentful Paint (6.1s) by an estimated 2.2 seconds. Removing or deferring unused JavaScript, especially from the Kinescope video player and Yandex analytics, and optimizing the loading of CSS and JavaScript files could dramatically improve performance and user experience.
Other Optimization Recommendations
Eliminate Render Blocking Resources
High Impact+25 points estimatedWhy It Matters:
CSS and JavaScript files are blocking initial page render, delaying LCP by 2.2 seconds and FCP by 2.2 seconds.
How to Fix:
Inline critical CSS for above-the-fold content directly in the HTML head. Move non-critical CSS files to load asynchronously using media='print' onload='this.media="all"'. Defer jQuery and other JavaScript files using async or defer attributes, or move them to the footer.
Optimize Font Loading Strategy
Medium Impact+10 points estimatedHow to Fix:
Preload the Caveat font files directly using <link rel='preload' as='font' type='font/woff2' crossorigin>. Self-host Google Fonts to reduce DNS lookups and external dependencies. Use font-display: swap in CSS to show fallback fonts immediately while custom fonts load.
