## Detailed findings

### Performance — 67/100

- **[FAIL]** Speed Index — 7.20s (good: <3.4s)
  - Fix: Your page loads very slowly visually. Prioritize critical rendering path: inline critical CSS, defer non-essential JS, preload hero image, and use a CDN.
  - Evidence: PSI-lab
- **[FAIL]** Total Page Weight — 5.9 MB, 142 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]** JavaScript Budget — 1239 KB — more than double the 600 KB budget
  - Fix: Audit what ships on a product page: split the bundle by route, defer every third-party tag until interaction or consent, and remove plugins whose bundle you cannot account for. Measure again after each removal.
  - Evidence: PSI-lab · 1239 KB JavaScript · confidence: high
- **[FAIL]** Request Budget — 142 requests — well past both the 80 budget and the cohort median of 140
  - Fix: Start with what loads before first paint: bundle the CSS/JS, sprite the icons, lazy-load every below-fold image, and remove duplicate tag-manager containers loading the same vendor twice.
  - Evidence: PSI-lab · 142 requests · confidence: high
- **[FAIL]** Unused Code (CSS + JS) — 489 KB wasted on unused code!
  - Fix: You're loading 489 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.
  - Evidence: PSI-lab
- **[WARN]** Total Blocking Time (TBT) — 484ms (good: <200ms)
  - Fix: 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.
  - Evidence: PSI-lab
- **[WARN]** Resource Hints (Preload/Preconnect)
  - Fix: Add resource hints: <link rel='preconnect' href='https://fonts.googleapis.com'> for third-party origins, <link rel='preload' as='image' href='hero.webp'> for critical resources.
  - Evidence: HTML-heuristic
- **[WARN]** Font Preloading — Custom fonts detected without preload hints
  - Fix: Preload your primary font: <link rel='preload' href='/fonts/main.woff2' as='font' type='font/woff2' crossorigin>. For Google Fonts: preconnect to fonts.gstatic.com.
  - Evidence: HTML-heuristic
- **[WARN]** Inline JavaScript Size — 1005 KB of inline JavaScript
  - Fix: Move large inline scripts to external files. Inline JS over 100 KB inflates HTML, prevents caching, and blocks the parser. External files can be cached, compressed, and deferred.
  - Evidence: PSI-lab
- **[INFO]** Third-party Services — Not measured — PageSpeed did not return the third-party audit for this URL
  - Evidence: PSI-lab
- **[INFO]** Render-blocking Resources — Not measured — PageSpeed did not return the render-blocking audit for this URL
  - Evidence: PSI-lab
- **[INFO]** Cache-Control Strategy — Not measured — no Cache-Control on the HTML document; static-asset caching was not sampled
  - Evidence: HTTP-header
- **[PASS]** Server Response Time (TTFB) — 70ms
  - Evidence: PSI-lab
- **[PASS]** First Contentful Paint (FCP) — 0.84s
  - Evidence: PSI-lab
- **[PASS]** Largest Contentful Paint (LCP) — 1.42s — Core Web Vital ✓
  - Evidence: PSI-lab
- **[PASS]** Cumulative Layout Shift (CLS) — 0.001 — Core Web Vital ✓
  - Evidence: PSI-lab
- **[PASS]** Text Compression (gzip/brotli) — All text resources properly compressed
  - Evidence: HTTP-header
- **[PASS]** Lazy Loading — 5% of images use native lazy loading (3/65)
  - Evidence: HTML-heuristic
- **[PASS]** HTTP/3 (QUIC) Support — HTTP/3 enabled via Alt-Svc header
  - Evidence: HTTP-header
- **[PASS]** Script Loading Strategy — 100% of scripts use async/defer/module (1 async, 0 defer, 1 module)
  - Evidence: HTML-heuristic
- **[PASS]** CSS File Count — 6 CSS file(s) — well consolidated
  - Evidence: HTML-heuristic

### SEO — 76/100

- **[FAIL]** Open Graph Tags
  - Fix: Add og:title, og:description, og:image (1200×630px), and og:type meta tags to every page.
  - Evidence: HTML-heuristic
- **[FAIL]** Structured Data (JSON-LD)
  - Fix: Add JSON-LD structured data: Product (with price, availability, reviews), Organization, BreadcrumbList, and WebSite schemas.
  - Evidence: schema
- **[WARN]** H1 Heading — 2 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 <meta name='twitter:card' content='summary_large_image'>, twitter:title, and twitter:image tags.
  - Evidence: HTML-heuristic
- **[WARN]** Image Alt Attributes — Only 62% of 65 images have alt text
  - Fix: 25 images are missing alt attributes. Add descriptive, keyword-rich alt text to every image.
  - Evidence: HTML-heuristic
- **[WARN]** Semantic HTML Structure — Only 3/6 semantic elements — missing: <article>, <main>, <aside>
  - Fix: Use semantic HTML5 elements: <header>, <nav>, <main>, <article>, <aside>, <footer>. These help search engines understand page structure and improve accessibility.
  - Evidence: HTML-heuristic
- **[WARN]** Sitemap in robots.txt — robots.txt exists but doesn't reference your sitemap
  - Fix: Add 'Sitemap: https://yourdomain.com/sitemap.xml' to your robots.txt file. This helps search engines discover your sitemap faster.
  - Evidence: HTML-heuristic
- **[WARN]** Accessibility Fundamentals — 2/4 a11y signals — missing: ARIA labels, skip navigation link
  - Fix: Add: ARIA landmark roles (role='navigation', role='main'), aria-label on interactive elements, a 'Skip to content' link, and lang attribute on <html>.
  - Evidence: HTML-heuristic
- **[WARN]** Image Dimension Attributes — Only 48% of images have width/height attributes
  - Fix: Add width and height attributes to all <img> tags. This prevents layout shifts (CLS) and helps browsers allocate space before images load.
  - Evidence: HTML-heuristic
- **[INFO]** Text-to-HTML Ratio — 0% ratio but 537 words — content is substantial; the low ratio is markup/inline-JS bloat, not thin content
  - Evidence: HTML-heuristic

  - Evidence: HTML-heuristic
- **[PASS]** Meta Robots Tag — index, follow
  - Evidence: HTML-heuristic
- **[PASS]** Favicon — Favicon detected
  - Evidence: file-probe
- **[PASS]** Image Format Optimization — 57% next-gen formats (37 WebP, 0 AVIF)
  - Evidence: HTML-heuristic

  - Evidence: HTML-heuristic
- **[PASS]** Internal Linking — 52 internal links — strong site navigation
  - Evidence: HTML-heuristic
- **[PASS]** Empty/Dead Links — 2 minor dead link(s) — acceptable
  - Evidence: HTML-heuristic
- **[PASS]** Sitemap Freshness — Newest <lastmod> 0 day(s) ago
  - Evidence: HTML-heuristic

### Security — 53/100

- **[FAIL]** HSTS (Strict-Transport-Security)
  - Fix: Add header: Strict-Transport-Security: max-age=31536000; includeSubDomains; preload — then submit to hstspreload.org.
  - Evidence: HTTP-header
- **[FAIL]** Content-Security-Policy (CSP)
  - Fix: Implement a CSP header. Start with: Content-Security-Policy: default-src 'self'; script-src 'self'; style-src 'self' 'unsafe-inline'; img-src 'self' data: — then gradually tighten.
  - Evidence: HTTP-header
- **[FAIL]** Clickjacking Protection
  - Fix: Add X-Frame-Options: DENY (or SAMEORIGIN if iframes are needed). Better: use CSP frame-ancestors 'self'.
  - Evidence: HTTP-header
- **[WARN]** CAA DNS Record — No CAA records — any CA can issue certificates for this domain
  - Fix: Publish CAA TXT records pinning your CA. For Let's Encrypt: `0 issue "letsencrypt.org"`. For multiple CAs add additional `0 issue "..."` records. Add `0 iodef "mailto:security@yourdomain.tld"` for misissuance reports.
  - Evidence: DNS
- **[WARN]** X-Content-Type-Options
  - Fix: Add header: X-Content-Type-Options: nosniff
  - Evidence: HTTP-header
- **[WARN]** Referrer-Policy
  - Fix: Add header: Referrer-Policy: strict-origin-when-cross-origin — this is the best balance between functionality and privacy.
  - Evidence: HTTP-header
- **[WARN]** Permissions-Policy
  - Fix: Add: Permissions-Policy: camera=(), microphone=(), geolocation=(), payment=() — disable APIs your site doesn't need.
  - Evidence: HTTP-header
- **[WARN]** Cookie Security Flags — 1 cookie(s): 1 missing Secure, 1 missing HttpOnly, 1 missing SameSite
  - Fix: Set all cookies with: Secure (HTTPS only), HttpOnly (no JS access), SameSite=Lax or Strict (CSRF protection). Session cookies MUST have all three.
  - Evidence: HTTP-header
- **[WARN]** Technology Disclosure — X-Powered-By: Nuxt
  - Fix: Hide server version: set ServerTokens Prod (Apache) or server_tokens off (Nginx). Remove X-Powered-By header completely.
  - Evidence: HTTP-header
- **[WARN]** security.txt (RFC 9116)
  - Fix: Create /.well-known/security.txt with Contact, Expires, and Preferred-Languages fields. See securitytxt.org for the generator.
  - Evidence: file-probe
- **[WARN]** CDN / WAF Protection
  - Fix: Add a CDN/WAF like Cloudflare (free tier), Sucuri, or Fastly. They provide DDoS protection, bot filtering, and SSL management.
  - Evidence: HTTP-header
- **[WARN]** Cookie Prefix Security — 1 session cookie(s) without __Secure- or __Host- prefix
  - Fix: Use __Host- prefix for session cookies: __Host-session=abc; Secure; Path=/; HttpOnly. The prefix enforces Secure flag and prevents cookie injection attacks.
  - Evidence: HTTP-header · confidence: low
- **[PASS]** SSL/TLS Certificate — Valid HTTPS connection established
  - Evidence: SSL
- **[PASS]** DNSSEC — Zone is DNSSEC-signed (DNSKEY published)
  - Evidence: DNS
- **[PASS]** HTTP → HTTPS Redirect — HTTP properly redirects to HTTPS
  - Evidence: HTTP-header
- **[PASS]** Subresource Integrity (SRI) — All cross-origin scripts are auto-updating provider scripts where SRI does not apply
  - Evidence: HTML-heuristic
- **[PASS]** Server Version Disclosure — Caddy — version hidden
  - Evidence: HTTP-header

### Mobile — 52/100

- **[FAIL]** Mobile Performance Score — 47/100 — critically slow
  - Fix: Your mobile experience is severely degraded. Priority fixes: 1) Reduce JavaScript, 2) Convert all images to WebP with responsive sizing, 3) Enable aggressive caching, 4) Use a CDN.
  - Evidence: PSI-lab
- **[FAIL]** Form Input Labels (WCAG 3.3.2) — Iba 0/2 inputs má label (0%)
  - Fix: 2 input elementov nemá label. Každý input musí mať priradený <label for="id">Text</label> alebo aria-label. Placeholder NIE je label (WCAG 3.3.2). Ak je checkout/registrácia formulár — toto znižuje konverziu a porušuje EN 301 549 (EAA 2026).
  - Evidence: HTML-heuristic
- **[FAIL]** Heading Hierarchy (WCAG 1.3.1) — Preskočené úrovne: h1→h3, h2→h4, h2→h5
  - Fix: Dodržuj poradie nadpisov h1 → h2 → h3 → h4 bez preskočenia. Screen readers používajú hierarchiu nadpisov na navigáciu. Ak potrebuješ menšie písmo ale rovnakú úroveň, použi CSS triedu, nie nižší heading tag.
  - Evidence: HTML-heuristic
- **[WARN]** Viewport Configuration — Present, but maximum-scale=1 disables pinch-to-zoom
  - Fix: Remove 'maximum-scale=1' and 'user-scalable=no' from your viewport meta tag. Use: <meta name='viewport' content='width=device-width, initial-scale=1'>
  - Evidence: HTML-heuristic
- **[WARN]** Touch Target Size — Some tappable targets are too small or too close together (Lighthouse tap-targets audit)
  - Fix: Ensure ALL interactive elements (buttons, links, form fields) are at least 48×48px with 8px minimum spacing between them. Pay special attention to: navigation menus, filter buttons, product variant selectors, and footer links.
  - Evidence: PSI-lab · Some tappable targets are too small or too close together (Lighthouse tap-targets audit)
- **[WARN]** Font Size Readability — Some text renders below the 12px legibility threshold (Lighthouse font-size audit)
  - Fix: Google's font-size audit flags text under 12px. Find the small text (often footer fine-print, captions, or cookie notices) and raise it; aim for a 16px+ body base with relative units (rem/em) so all text scales legibly on mobile.
  - Evidence: PSI-lab · Some text renders below the 12px legibility threshold (Lighthouse font-size audit)
- **[WARN]** PWA Features
  - Fix: Consider adding Progressive Web App features: 1) Create manifest.json with app name, icons, and theme color, 2) Register a service worker for offline caching. This makes your store installable on mobile.
  - Evidence: HTML-heuristic
- **[WARN]** Theme Color
  - Fix: Add <meta name='theme-color' content='#your-brand-color'> to match your brand. Browsers use this to color the address bar, task switcher, and PWA chrome.
  - Evidence: HTML-heuristic
- **[WARN]** Inline CSS Size — 368 KB of inline CSS
  - Fix: Extract inline styles to external CSS files. Inline CSS larger than 50 KB increases HTML payload and cannot be cached separately. Keep only critical above-the-fold CSS inline.
  - Evidence: HTML-heuristic
- **[WARN]** Responsive Images (srcset) — 65 images without responsive sizing
  - Fix: Add srcset and sizes attributes to <img> tags to serve appropriately sized images for each screen. Mobile devices shouldn't download 1920px desktop images.
  - Evidence: HTML-heuristic
- **[WARN]** SK/CZ Local Payment Methods — Iba 2 SK/CZ metód (Tatra Pay, QR platba / Pay by square)
  - Fix: Pridaj ďalšie SK/CZ local methods: ComGate, GoPay, Barion, Besteron, PayU. SK zákazníci preferujú bankové tlačidlá a QR platbu pred kartou.
  - Evidence: HTML-heuristic
- **[INFO]** Express Checkout (Apple Pay + Google Pay) — Apple Pay / Google Pay nedetekované na homepage — express checkout sa zvyčajne zobrazí až v košíku/checkoute
  - Evidence: HTML-heuristic
- **[PASS]** Content Fits Viewport — No horizontal scrolling needed
  - Evidence: HTML-heuristic
- **[PASS]** Responsive Design Techniques — Flexbox, CSS Grid, Media queries detected
  - Evidence: HTML-heuristic
- **[PASS]** Mobile Navigation (Semantic) — <nav> element present — proper navigation landmark
  - Evidence: HTML-heuristic
- **[PASS]** Form Input Types — Optimized: 1 email
  - Evidence: HTML-heuristic
- **[PASS]** Payment Methods Detected — 2 method(s): Tatra Pay, QR platba / Pay by square
  - Evidence: HTML-heuristic
- **[PASS]** Link Text Quality (WCAG 2.4.4) — Všetky odkazy majú popisný text
  - Evidence: HTML-heuristic

### AI Readiness — 50/100

- **[FAIL]** Structured Data Foundation
  - Fix: Add JSON-LD structured data immediately. Priority order: 1) Organization, 2) Product (with offers), 3) BreadcrumbList, 4) WebSite+SearchAction, 5) FAQPage. Use JSON-LD format exclusively — not Microdata or RDFa.
  - Evidence: schema
- **[FAIL]** Organization Schema + Entity Linking
  - Fix: Add Organization (or LocalBusiness for physical stores) schema with: name, logo, url, description, contactPoint, address, and sameAs linking to all your official profiles (LinkedIn, Facebook, Wikipedia if available).
  - Evidence: schema
- **[FAIL]** Heading Hierarchy for AI — 2 H1, 8 H2, 3 H3 — poor structure
  - Fix: Use exactly 1 H1 (page title), then organize content with H2 sections and H3 subsections. Each heading should describe the content that follows. Never skip heading levels (H1→H3 without H2).
  - Evidence: HTML-heuristic
- **[FAIL]** Content Freshness Signals
  - Fix: Add dateModified and datePublished to your JSON-LD schema, and display a visible 'Last updated' date on the page. Update content quarterly at minimum. AI heavily favors fresh, maintained content.
  - Evidence: HTML-heuristic
- **[FAIL]** Entity Clarity & Brand Signals
  - Fix: Your brand has weak entity signals. Add: 1) Complete OG meta tags, 2) Organization schema with sameAs linking to all official profiles, 3) Consistent NAP (Name, Address, Phone) across the web.
  - Evidence: HTML-heuristic
- **[FAIL]** Image Alt Text Quality for AI — Only 15% quality alt text — 25 missing, 15 poor
  - Fix: Audit all images: add descriptive alt text (3-15 words) to every <img>. Include product names, features, materials, colors. This is critical for visual AI search and accessibility compliance.
  - Evidence: HTML-heuristic
- **[WARN]** FAQ Schema (Direct AI Answers)
  - Fix: Add FAQPage schema to every product page and category page. Include 3-5 Q&As per page covering: product specifications, shipping, returns, usage instructions. Format: question (full sentence) + answer (75-150 words).
  - Evidence: schema
- **[WARN]** Breadcrumb Schema
  - Fix: Add BreadcrumbList schema reflecting your category hierarchy: Home → Category → Subcategory → Product. Each item needs name and URL.
  - Evidence: schema
- **[WARN]** Site Search Schema (SearchAction)
  - Fix: Add WebSite schema with potentialAction: SearchAction. Define your search URL template so AI assistants and Google can search your store programmatically.
  - Evidence: schema
- **[WARN]** Answer-First Content Format — Content doesn't start with a strong summary paragraph
  - Fix: Place your most important information in the first 100 words of the page. Use the BLUF method (Bottom Line Up Front): start with what the product IS and why it matters, then elaborate.
  - Evidence: HTML-heuristic
- **[WARN]** Semantic HTML Structure — 3/6 elements — missing: <article>, <main>, <aside>
  - Fix: Add: <article>, <main>, <aside>. Semantic HTML tells AI what's content (<article>), navigation (<nav>), sidebar (<aside>), etc. — without relying on CSS classes or visual layout.
  - Evidence: HTML-heuristic
- **[WARN]** Structured Content (Lists & Tables) — 4 lists found — consider adding comparison tables
  - Fix: Add comparison tables to your content. Use <ul>/<ol> for feature lists, specifications, and benefits. Use <table> for product comparisons, pricing tiers, and specifications. AI extracts structured content much faster than paragraphs.
  - Evidence: HTML-heuristic
- **[WARN]** Author Expertise Signals (E-E-A-T)
  - Fix: For content pages (blog, guides, about): add Article/BlogPosting schema with author property linking to Person schema. Include the author's jobTitle, credentials, and social profiles.
  - Evidence: HTML-heuristic
- **[WARN]** Product Feed (AI Commerce)
  - Fix: Create a Google Merchant Center / product feed (XML or CSV). Expose it at a consistent URL and reference it in your sitemap. AI shopping assistants and comparison engines use product feeds for catalog discovery. Tip: validate your Heureka / Zboží / Glami / Merchant feeds for free with Mergado's audit.
  - Evidence: file-probe · probed /feed/products.xml, /google-shopping.xml, /export/google-shopping.xml — none returned a product feed
- **[WARN]** Heureka XML Feed
  - Fix: Vygeneruj Heureka XML feed na /feed/heureka.xml (alebo /export/heureka.xml). PrestaShop má modul Heureka.cz, WooCommerce má pluginy. Štruktúra: <SHOP><SHOPITEM>...</SHOPITEM></SHOP> s ITEM_ID/PRODUCTNAME/URL/PRICE_VAT/CATEGORYTEXT (povinné) + EAN/PARAM/DELIVERY_DATE (highly recommended pre ranking).
  - Evidence: file-probe
- **[WARN]** Extractable Answer Blocks — 17 paragraphs, avg 15 words — too short for citation
  - Fix: Optimal paragraphs for AI citation are 40-80 words. Break long paragraphs into focused, self-contained answer blocks. Each should make one clear point that AI can extract and quote.
  - Evidence: HTML-heuristic
- **[WARN]** Statistics & Data Presence — Only 1 data point(s) — add more
  - Fix: Add specific statistics, percentages, dollar amounts, and quantified claims. E.g., '93% of customers report...', 'saves an average of €200/year', '3x faster than...' Data makes content citable.
  - Evidence: HTML-heuristic
- **[WARN]** Section Length Optimization — Avg section: 50 words — only 22% in 80-200 word optimal range
  - Fix: Restructure content into sections of 120-180 words between H2/H3 headings. Each section should cover one topic completely. Split sections over 300 words, expand sections under 80 words.
  - Evidence: HTML-heuristic
- **[WARN]** Q&A Format Headings
  - Fix: Add H2/H3 headings phrased as questions your customers ask: 'How much does shipping cost?', 'What sizes are available?', 'How do I return an item?' Follow each with a direct, concise answer.
  - Evidence: HTML-heuristic
- **[WARN]** Common Question Coverage — Answers 3/5 — missing: returns/refunds, payment
  - Fix: Add clear content answering the questions shoppers (and AI assistants) ask: pricing, shipping options & cost, returns/refund policy, stock availability, and accepted payment methods. A visible FAQ or info section covering these is ideal.
  - Evidence: HTML-heuristic
- **[WARN]** Return Policy Schema
  - Fix: Add MerchantReturnPolicy schema with: returnPolicyCategory (e.g., MerchantReturnFiniteReturnWindow), merchantReturnDays, returnMethod, returnFees. Link it from Product/Offer via hasMerchantReturnPolicy.
  - Evidence: schema
- **[WARN]** Shipping Details Schema
  - Fix: Add OfferShippingDetails schema with: shippingRate, shippingDestination, deliveryTime (handlingTime + transitTime). AI agents deprioritize products without shipping info.
  - Evidence: schema
- **[WARN]** Knowledge Graph Readiness — 1/4 signals — missing: @id in JSON-LD, sameAs links (Wikipedia, LinkedIn), Organization schema
  - Fix: Add: @id in JSON-LD, sameAs links (Wikipedia, LinkedIn), Organization schema. Use @id in JSON-LD to create a unique node identifier. Ensure your brand name is identical in title, schema, and OG tags. Link to Wikipedia/Wikidata via sameAs.
  - Evidence: HTML-heuristic
- **[WARN]** Content Readability for AI — Grade 19 — too complex for broad AI citation (technical threshold: 14)
  - Fix: Simplify sentences (target 15-20 words average), use common words, break complex ideas into shorter paragraphs. AI extracts content for general audiences — if it's too academic, AI skips it.
  - Evidence: HTML-heuristic
- **[WARN]** Expert Quotations & Citations
  - Fix: Add 2-3 expert quotes or data citations per major page. Use <blockquote> for quotes and link to authoritative sources (.gov, .edu, Wikipedia, industry reports).
  - Evidence: HTML-heuristic
- **[WARN]** WebMCP Agentic Readiness
  - Fix: WebMCP (W3C Community Group standard, Chrome 146+) lets pages declare structured tools for AI agents. Add toolname and tooldescription attributes to <form> elements, or include a <script type='application/webmcp+json'> manifest.
  - Evidence: HTML-heuristic
- **[WARN]** Content-to-Boilerplate Ratio — No <main> or <article> elements — AI can't isolate content from boilerplate
  - Fix: Add <main> around your primary content and <article> around self-contained content blocks. This creates clear boundaries for AI content extraction.
  - Evidence: HTML-heuristic
- **[WARN]** Trust Widget — Žiaden trust widget (Heureka / Trustpilot / AggregateRating) nedetekovaný
  - Fix: Pre SK/CZ shopy: inštaluj Heureka Ověřeno zákazníky widget (zadarmo pre overených predajcov — https://sluzby.heureka.sk). Alternatívne: Trustpilot, Google Reviews s AggregateRating schema. Trust widget na product + kategória + footer.
  - Evidence: HTML-heuristic
- **[INFO]** llms.txt (AI Site Descriptor) — Not present — not required for AI visibility
  - Evidence: file-probe
- **[INFO]** llms-full.txt (Complete AI Content) — Not present — not required for AI visibility
  - Evidence: file-probe
- **[INFO]** Product Schema Completeness — No Product schema on this homepage — Product schema lives on product detail pages, and we couldn't identify one to sample
  - Evidence: schema
- **[INFO]** Reviews & Ratings Schema — No review schema on this homepage — review/rating schema typically lives on product pages
  - Evidence: schema
- **[INFO]** AI Plugin Manifest — Not present — not required (the ChatGPT-plugins manifest was retired in 2024)
  - Evidence: file-probe
- **[INFO]** GTIN/EAN Coverage — No product feed was sampled — GTIN/EAN coverage could not be verified
  - Evidence: HTML-heuristic
- **[INFO]** Speakable Content (Voice AI) — Not present — optional; SpeakableSpecification has limited assistant adoption
  - Evidence: HTML-heuristic
- **[INFO]** ai.txt (AI Permissions) — Not present — optional; AI-bot permissions are enforced via robots.txt, not ai.txt
  - Evidence: file-probe
- **[INFO]** Agent-Commerce Readiness — 50/100 — čiastočne pripravené (Prístup 100 · Porozumenie 0 · Objaviteľnosť 50 · Transakcia 50)
- **[INFO]** Agent: Prístup — dostane sa agent dnu — 100/100 (2 signály/-ov)
- **[INFO]** Agent: Porozumenie — rozumie produktom — 0/100 (2 signály/-ov)

- **[PASS]** Content Depth for AI — 537 words — rich content for AI analysis and citation
  - Evidence: HTML-heuristic
- **[PASS]** Internal Link Density — 97 contextual internal links per 1,000 words — strong knowledge graph signal
  - Evidence: HTML-heuristic
- **[PASS]** Canonical Tag for AI Deduplication — Self-referencing canonical — clean signal for AI
  - Evidence: HTML-heuristic

### GDPR — 77/100

- **[FAIL]** Consumer Dispute Resolution Links — No EU ODR platform or supervisory-authority link found
  - Fix: Add the EU ODR platform link (https://ec.europa.eu/consumers/odr) and your national authority (SK: Slovenská obchodná inšpekcia / soi.sk, CZ: Česká obchodní inspekce / coi.cz) to the footer and Terms & Conditions.
  - Evidence: HTML-heuristic
- **[WARN]** Cookie Policy
  - Fix: Create a separate cookie policy page listing every cookie by: name, provider, purpose, category (necessary/analytics/marketing), and expiration. Most CMPs auto-generate this.

  - Evidence: HTML-heuristic
- **[WARN]** Newsletter Consent — Newsletter signup found without visible consent checkbox
  - Fix: Add an unchecked consent checkbox to your newsletter form: 'I agree to receive marketing emails and have read the Privacy Policy [link].' Pre-checked boxes are not valid consent under GDPR.
  - Evidence: HTML-heuristic
- **[INFO]** Cookie Consent Banner (CMP) — No CMP in server HTML, but GTM is present — consent banner may be injected at runtime (not verifiable server-side)

### Vulnerability — 76/100

- **[FAIL]** Form CSRF Protection — 1 form(s) without CSRF tokens
  - Fix: Add CSRF token validation to every form. Most CMS frameworks have built-in CSRF protection — make sure it's enabled on all forms, including search and newsletter signup.
  - Evidence: HTML-heuristic · confidence: low
- **[FAIL]** Payment Page Security — Payment page missing: No HSTS, No CSP, No X-Content-Type-Options, No clickjacking protection
  - Fix: CRITICAL: Your payment page is missing security headers: No HSTS, No CSP, No X-Content-Type-Options, No clickjacking protection. PCI DSS Requirement 6.5 mandates protection against common vulnerabilities on pages handling card data.
  - Evidence: file-probe
- **[WARN]** X-Powered-By Header — Nuxt
  - Fix: Remove the X-Powered-By header. PHP: add 'expose_php = Off' to php.ini. Express.js: app.disable('x-powered-by').
  - Evidence: file-probe
- **[WARN]** Inline JavaScript Exposure — 1005 KB of inline JavaScript
  - Fix: Move inline scripts to external files. Inline JavaScript expands the attack surface for XSS and makes CSP harder to implement (requires unsafe-inline).
  - Evidence: HTML-heuristic · confidence: low
- **[WARN]** DMARC Policy (Email Auth) — DMARC set to p=none (monitoring only, no enforcement)
  - Fix: Upgrade DMARC policy from p=none to p=quarantine or p=reject. p=none only monitors — it doesn't block spoofed emails. Start with quarantine, then move to reject after verifying legitimate emails pass.
  - Evidence: DNS
- **[WARN]** Cross-Origin Isolation
  - Fix: Add Cross-Origin-Opener-Policy: same-origin and Cross-Origin-Resource-Policy: same-origin headers. These protect against Spectre-type side-channel attacks.
  - Evidence: HTTP-header
- **[PASS]** CMS Version Disclosure — No generator tag — CMS identity hidden
  - Evidence: HTML-heuristic
- **[PASS]** Sensitive Files Exposed — .env, .git, composer.json — all properly blocked
  - Evidence: file-probe
- **[PASS]** Install Script Exposed — No /install/ or /setup/ paths accessible
  - Evidence: file-probe
- **[PASS]** Directory Listing — Disabled — file structure hidden
  - Evidence: file-probe

  - Evidence: file-probe
- **[PASS]** Debug Mode / Error Exposure — No debug indicators found in page output
  - Evidence: HTML-heuristic
- **[PASS]** Bootstrap Version — Bootstrap 5.3.3
  - Evidence: file-probe
- **[PASS]** SPF Record (Email Security) — SPF configured: v=spf1 a mx include:_spf.smartweb.eu -all
  - Evidence: DNS
- **[PASS]** DKIM Signing (Email Auth) — DKIM configured (selectors: default, mail)
  - Evidence: file-probe

### NIS2

- **[INFO]** NIS2 Compliance — Scope undetermined — IČO/company enrichment unavailable for this domain.

### Accessibility — 23/100

- **[FAIL]** Image Alt Text — 25 of 65 images have no alt attribute
  - Fix: Add descriptive alt text to every meaningful image; use alt="" for purely decorative ones so screen readers skip them.
  - Evidence: HTML-heuristic
- **[FAIL]** Form Labels — 2 of 2 form inputs have no associated label
  - Fix: Associate every input with a <label for> (or aria-label / aria-labelledby). Placeholders are not labels.
  - Evidence: HTML-heuristic
- **[FAIL]** Landmark Regions — No <main> landmark region found
  - Fix: Wrap the primary content in <main> and use <nav>, <header>, <footer> for the page regions.
  - Evidence: HTML-heuristic
- **[FAIL]** Zoom & Scaling — The viewport meta tag disables pinch-zoom (user-scalable=no / maximum-scale=1)
  - Fix: Remove user-scalable=no and maximum-scale from the viewport tag: <meta name="viewport" content="width=device-width, initial-scale=1">.
  - Evidence: HTML-heuristic
- **[WARN]** Heading Structure — 2 <h1> headings found (expected one)
  - Fix: Use a single <h1> and don't jump heading levels (e.g. <h2> straight to <h4>).
  - Evidence: HTML-heuristic
- **[WARN]** Skip Link — No skip-to-content link detected
  - Fix: Add a visually-hidden "Skip to content" link as the first focusable element, targeting <main id="main">.
