## Detailné nálezy
### Výkon — 58/100
- **[CHYBA]** Total Page Weight — 4.1 MB, 334 requests — too heavy!
- Riešenie: Critical: your page is over 3 MB. 1) Convert all images to WebP/AVIF, 2) Lazy load everything below the fold, 3) Remove unused plugins, 4) Combine and minify CSS/JS, 5) Enable brotli compression.
- Dôkaz: PSI-lab
- **[CHYBA]** Unused Code (CSS + JS) — 1109 KB wasted on unused code!
- Riešenie: You're loading 1109 KB of code that isn't used on this page. 1) Audit plugins and remove unused ones, 2) Use code-splitting for page-specific JS, 3) Run PurgeCSS on your stylesheets.
- Dôkaz: PSI-lab
- **[UPOZORNENIE]** Largest Contentful Paint (LCP) — 2.61s (good: <2.5s) — Core Web Vital
- Riešenie: Optimize your largest element (usually hero image or product image): preload it with , use WebP/AVIF format, set explicit width/height, and serve from CDN.
- Dôkaz: PSI-lab
- **[UPOZORNENIE]** Total Blocking Time (TBT) — 560ms (good: <200ms)
- Riešenie: Reduce JavaScript execution: defer non-critical scripts, code-split large bundles, remove unused plugins. Third-party scripts (analytics, chat, ads) are often the biggest offenders.
- Dôkaz: PSI-lab
- **[UPOZORNENIE]** Speed Index — 3.56s (good: <3.4s)
- Riešenie: Speed Index measures visual completeness over time. Improve it by: prioritizing above-fold content, preloading critical resources, and minimizing render-blocking assets.
- Dôkaz: PSI-lab
- **[UPOZORNENIE]** Resource Hints (Preload/Preconnect)
- Riešenie: Add resource hints: for third-party origins, for critical resources.
- Dôkaz: HTML-heuristic
- **[UPOZORNENIE]** Lazy Loading — 606 images without lazy loading
- Riešenie: Add loading='lazy' to all images below the fold. Keep the hero/LCP image eager-loaded. Native lazy loading is supported by all modern browsers.
- Dôkaz: HTML-heuristic
- **[UPOZORNENIE]** Cache-Control Strategy — no-store, no-cache, must-revalidate
- Riešenie: Set appropriate cache headers: static assets should have max-age=31536000 with versioned filenames. HTML pages can use max-age=0 with ETag for revalidation.
- Dôkaz: HTTP-header
- **[UPOZORNENIE]** Script Loading Strategy — Only 43% of 7 scripts use async/defer
- Riešenie: Add 'defer' to scripts that don't need to run immediately, 'async' for independent scripts. Use type='module' for modern ES modules. Only critical inline scripts should be synchronous.
- Dôkaz: HTML-heuristic
- **[UPOZORNENIE]** CSS File Count — 7 CSS files loaded
- Riešenie: Consolidate CSS files by bundling them into 1-3 files. Each CSS file is a separate HTTP request that blocks rendering until downloaded.
- Dôkaz: HTML-heuristic
- **[UPOZORNENIE]** Critical CSS Strategy — 7 CSS files without critical CSS extraction
- Riešenie: Extract critical above-the-fold CSS and inline it in . Load remaining CSS asynchronously: .
- Dôkaz: PSI-lab
- **[UPOZORNENIE]** Connection Hint Coverage — 4 external domains without preconnect
- Riešenie: Add for key third-party domains: sub3.tpd.sk, www.google.com, cdn.luigisbox.com. Preconnect saves 100-300ms per domain by starting DNS+TCP+TLS early.
- Dôkaz: PSI-lab
