## Detailed findings
### Performance — 70/100
- **[FAIL]** Total Page Weight — 3.6 MB, 140 requests — too heavy!
- Fix: 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.
- Evidence: PSI-lab
- **[FAIL]** CSS File Count — 91 CSS files — too many!
- Fix: Bundle your CSS files into 1-3 files maximum. Use a build tool (Webpack, Vite, Gulp) to concatenate and minify. Critical CSS should be inlined, the rest deferred.
- Evidence: HTML-heuristic
- **[WARN]** Largest Contentful Paint (LCP) — 3.73s (good: <2.5s) — Core Web Vital
- Fix: 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.
- Evidence: PSI-lab
- **[WARN]** Unused Code (CSS + JS) — 180 KB unused (CSS: 45 KB, JS: 135 KB)
- Fix: Remove unused CSS with PurgeCSS or UnCSS. Code-split JavaScript so only needed code loads per page. Audit plugins — each adds CSS/JS.
- Evidence: PSI-lab
- **[WARN]** Font Loading Strategy — font-display: auto
- Fix: Use font-display: swap (shows fallback immediately, swaps when loaded) or font-display: optional (best for performance — may skip custom font on slow connections).
- Evidence: HTML-heuristic
- **[WARN]** Script Loading Strategy — Only 40% of 52 scripts use async/defer
- Fix: 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.
- Evidence: HTML-heuristic
- **[WARN]** Font Preloading — Custom fonts detected without preload hints
- Fix: Preload your primary font: . For Google Fonts: preconnect to fonts.gstatic.com.
- Evidence: HTML-heuristic
- **[WARN]** Critical CSS Strategy — 91 CSS files without critical CSS extraction
- Fix: Extract critical above-the-fold CSS and inline it in . Load remaining CSS asynchronously: .
- Evidence: PSI-lab
- **[WARN]** Connection Hint Coverage — 4 external domains without preconnect
- Fix: Add for key third-party domains: cdnjs.cloudflare.com, www.googletagmanager.com, t.contentsquare.net. Preconnect saves 100-300ms per domain by starting DNS+TCP+TLS early.
- Evidence: PSI-lab
- **[INFO]** Render-blocking Resources — Not measured — PageSpeed did not return the render-blocking audit for this URL
- Evidence: PSI-lab
- **[PASS]** Server Response Time (TTFB) — 89ms
- Evidence: PSI-lab
- **[PASS]** First Contentful Paint (FCP) — 0.76s
- Evidence: PSI-lab
- **[PASS]** Total Blocking Time (TBT) — 186ms
- Evidence: PSI-lab
- **[PASS]** Cumulative Layout Shift (CLS) — 0.077 — Core Web Vital ✓
- Evidence: PSI-lab
- **[PASS]** Speed Index — 2.86s
- Evidence: PSI-lab
- **[PASS]** Text Compression (gzip/brotli) — All text resources properly compressed
- Evidence: HTTP-header
- **[PASS]** Resource Hints (Preload/Preconnect) — 1 preload, 0 preconnect hint(s)
- Evidence: HTML-heuristic
- **[PASS]** Lazy Loading — 49% of images use native lazy loading (102/208)
- Evidence: HTML-heuristic
### SEO — 78/100
- **[FAIL]** Content Structure (H2 Headings)
- Fix: Add H2 subheadings to structure your content. Each major section should have a descriptive H2.
- Evidence: HTML-heuristic
- **[FAIL]** XML Sitemap
- Fix: Generate an XML sitemap at /sitemap.xml listing all important pages. Exclude noindex pages, filters, and duplicate URLs. Reference it in robots.txt.
- Evidence: file-probe
- **[WARN]** Meta Description — 116 chars (optimal: 120-160)
- Fix: Expand your description to at least 120 characters. Include benefits, a CTA, and your target keyword.
- Evidence: HTML-heuristic
- **[WARN]** H1 Heading — 5 H1 tags (should be exactly 1)
- Fix: Consolidate to exactly one H1 tag per page. Use H2-H6 for subheadings.
- Evidence: HTML-heuristic
- **[WARN]** Twitter/X Cards
- Fix: Add , twitter:title, and twitter:image tags.
- Evidence: HTML-heuristic
- **[WARN]** Image Format Optimization — Only 1% next-gen formats — 5 legacy images remain
- Fix: Convert remaining JPEG/PNG images to WebP (30-50% smaller) or AVIF (50-70% smaller). Use element for browser fallback.
- Evidence: HTML-heuristic
- **[WARN]** Canonical URL Consistency — Canonical points to different URL: https://www.metronet.sk/
- Fix: Your canonical URL doesn't match the current page URL. Ensure the canonical points to the preferred version (with or without trailing slash, www vs non-www). Inconsistent canonicals confuse search engines.
- Evidence: HTML-heuristic
- **[WARN]** Internal Linking — Only 3 internal links
- Fix: Add more internal links to related content. Target 5+ internal links per page for strong site crawlability.
- Evidence: HTML-heuristic
- **[WARN]** Empty/Dead Links — 9 dead links (0 empty, 9 hash-only, 0 javascript:void)
- Fix: Replace empty href='', href='#', and href='javascript:void(0)' with actual URLs. If interactive, use
