## Detailed findings

### Performance — 83/100

- **[FAIL]** JavaScript Budget — 1450 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 · 1450 KB JavaScript · confidence: high
- **[FAIL]** Unused Code (CSS + JS) — 790 KB wasted on unused code!
  - Fix: You're loading 790 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]** Cumulative Layout Shift (CLS) — 0.187 (good: <0.1) — Core Web Vital
  - Fix: Set explicit width/height on all images and videos. Reserve space for ads and dynamic content. Avoid injecting content above existing content (cookie banners, notification bars).
  - Evidence: PSI-lab
- **[WARN]** Total Page Weight — 2.5 MB, 78 requests (optimal: <1.5 MB, <50 req)
  - Fix: Reduce page weight: compress images to WebP (saves 30-50%), enable text compression (gzip/brotli), lazy load below-fold images, remove unused CSS/JS.
  - Evidence: PSI-lab
- **[WARN]** Lazy Loading — 55 images without lazy loading
  - Fix: 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.
  - Evidence: HTML-heuristic
- **[WARN]** Cache-Control Strategy — no-store, no-cache, must-revalidate, no-cache, private
  - Fix: 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.
  - Evidence: HTTP-header
- **[WARN]** Script Loading Strategy — Only 40% of 10 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]** Connection Hint Coverage — 5 external domains without preconnect
  - Fix: Add <link rel='preconnect'> for key third-party domains: www.googletagmanager.com, connect.facebook.net, cdn.popt.in. Preconnect saves 100-300ms per domain by starting DNS+TCP+TLS early.
  - 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
- **[PASS]** Server Response Time (TTFB) — 22ms
  - Evidence: PSI-lab
- **[PASS]** First Contentful Paint (FCP) — 0.93s
  - Evidence: PSI-lab
- **[PASS]** Largest Contentful Paint (LCP) — 1.17s — Core Web Vital ✓
  - Evidence: PSI-lab
- **[PASS]** Total Blocking Time (TBT) — 5ms
  - Evidence: PSI-lab
- **[PASS]** Speed Index — 1.07s
  - Evidence: PSI-lab
- **[PASS]** Request Budget — 78 requests — within the budget of 80
  - Evidence: PSI-lab · 78 requests · confidence: high
- **[PASS]** Text Compression (gzip/brotli) — All text resources properly compressed
  - Evidence: HTTP-header
- **[PASS]** Resource Hints (Preload/Preconnect) — 1 preload, 1 preconnect hint(s)
  - Evidence: HTML-heuristic
- **[PASS]** HTTP/3 (QUIC) Support — HTTP/3 enabled via Alt-Svc header
  - Evidence: HTTP-header
- **[PASS]** CSS File Count — 5 CSS file(s) — well consolidated
  - Evidence: HTML-heuristic

### SEO — 95/100

- **[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 Format Optimization — 0% next-gen formats — 13 JPEG, 1 PNG images
  - Fix: Convert all images to WebP format. Most CMS platforms have plugins for automatic WebP conversion. Use AVIF for even better compression.
  - Evidence: HTML-heuristic
- **[WARN]** Canonical URL Consistency — Canonical points to different URL: https://www.elstrote.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
- **[INFO]** Text-to-HTML Ratio — 5% ratio but 1224 words — content is substantial; the low ratio is markup/inline-JS bloat, not thin content
  - Evidence: HTML-heuristic
- **[PASS]** Meta Title — 49 chars — "Nákupný portál Elstrote® s OOPP pre B2C &amp; B2B"
  - Evidence: HTML-heuristic
- **[PASS]** Meta Description — 135 chars
  - Evidence: HTML-heuristic
- **[PASS]** H1 Heading — "Víta Vás  Elstrote® obchod  s OOPP pre B2C &amp; B2B"
  - Evidence: HTML-heuristic
- **[PASS]** Content Structure (H2 Headings) — 7 H2 subheadings found
  - Evidence: HTML-heuristic
- **[PASS]** Open Graph Tags — og:title, og:description, og:image, og:type
  - Evidence: HTML-heuristic
- **[PASS]** Open Graph Image Format — image/webp
  - Evidence: HTML-heuristic
- **[PASS]** Canonical URL — https://www.elstrote.sk/
  - Evidence: HTML-heuristic
- **[PASS]** Structured Data (JSON-LD) — 1 block(s): Organization
  - Evidence: schema
- **[PASS]** JSON-LD Validity — 1 block(s) parse cleanly
  - Evidence: HTML-heuristic
- **[PASS]** robots.txt — Present, references sitemap
  - Evidence: file-probe
- **[PASS]** XML Sitemap — Found with 1022 URLs
  - Evidence: file-probe
- **[PASS]** HTML Language Attribute — lang="sk"
  - Evidence: HTML-heuristic
- **[PASS]** Image Alt Attributes — 98% of 55 images have alt text
  - Evidence: HTML-heuristic
- **[PASS]** Meta Robots Tag — index,follow
  - Evidence: HTML-heuristic
- **[PASS]** Favicon — Favicon detected
  - Evidence: file-probe
- **[PASS]** Semantic HTML Structure — 4/6 semantic elements: <nav>, <main>, <header>, <footer>
  - Evidence: HTML-heuristic
- **[PASS]** Content Depth — 1224 words — sufficient content
  - Evidence: HTML-heuristic
- **[PASS]** Deep Heading Hierarchy — H2: 7, H3: 11 — well-structured content
  - Evidence: HTML-heuristic
- **[PASS]** Internal Linking — 57 internal links — strong site navigation
  - Evidence: HTML-heuristic
- **[PASS]** Empty/Dead Links — 4 minor dead link(s) — acceptable
  - Evidence: HTML-heuristic
- **[PASS]** Accessibility Fundamentals — 4/4 a11y signals: 204 ARIA roles, 13 ARIA labels, skip link, lang="sk"
  - Evidence: HTML-heuristic

### Security — 57/100

- **[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
- **[WARN]** DNSSEC — No DNSKEY records — zone is unsigned
  - Fix: Enable DNSSEC at your DNS host (most modern registrars offer 1-click activation: Cloudflare, Route 53, Google Cloud DNS, web.sk, websupport.sk). Verify via dnsviz.net afterwards.
  - Evidence: DNS
- **[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]** HTTP → HTTPS Redirect
  - Fix: Configure a 301 redirect from http:// to https:// for all pages. In Apache: RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
  - 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 — 3 cookie(s): 2 missing HttpOnly, 2 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]** Subresource Integrity (SRI) — Only 0/8 SRI-eligible third-party scripts have integrity hashes (2 auto-updating provider script(s) excluded — SRI not applicable)
  - Fix: Add integrity='sha384-...' and crossorigin='anonymous' to version-pinned third-party <script> tags (use srihash.org). Auto-updating provider scripts (analytics, payment SDKs, consent tools) are correctly excluded — they can't use SRI.
  - Evidence: HTML-heuristic
- **[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]** Iframe Sandboxing — 1/1 unknown iframe(s) without sandbox attribute
  - Fix: Add a sandbox attribute to non-provider <iframe> elements. Use sandbox='allow-scripts allow-same-origin' for third-party embeds. Trusted media/payment embeds (YouTube, Maps, Stripe, reCAPTCHA) are correctly excluded — they need full privileges to work.
  - Evidence: HTML-heuristic · confidence: low
- **[INFO]** Cookie Prefix Security — 1 session cookie(s) already have Secure + HttpOnly + SameSite; adding the __Host- prefix is a cosmetic hardening nicety
  - Evidence: HTTP-header · 1 session cookie(s), all with Secure+HttpOnly+SameSite · confidence: low
- **[PASS]** SSL/TLS Certificate — Valid HTTPS connection established
  - Evidence: SSL
- **[PASS]** Clickjacking Protection — X-Frame-Options: SAMEORIGIN, SAMEORIGIN
  - Evidence: HTTP-header
- **[PASS]** X-Content-Type-Options — nosniff
  - Evidence: HTTP-header
- **[PASS]** Technology Disclosure — Server: openresty (no version)
  - Evidence: HTTP-header
- **[PASS]** security.txt (RFC 9116) — Present at /.well-known/security.txt
  - Evidence: file-probe
- **[PASS]** Server Version Disclosure — openresty — version hidden
  - Evidence: HTTP-header
- **[PASS]** Password Field Security — 1 password field(s) — allow password manager autofill
  - Evidence: HTTP-header

### Mobile — 62/100

- **[WARN]** Mobile Performance Score — 55/100 (target: 90+)
  - Fix: Optimize for mobile: compress images to WebP, defer non-critical JS, reduce CSS file size. Mobile CPUs are several times slower than desktop — what's fast on desktop is slow on mobile.
  - Evidence: PSI-lab
- **[WARN]** Desktop/Mobile Performance Gap — Desktop: 87 vs Mobile: 55 (32 point gap)
  - Fix: Your desktop experience is significantly better than mobile. Focus on: reducing JavaScript (mobile CPUs are slower), serving responsive images (smaller files for smaller screens), and minimizing main-thread work.
  - 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: Set minimum 16px font size for body text. Use relative units (rem/em) instead of px for scalability. Product titles: 18px+, prices: 20px+, CTAs: 16px+ with bold.
  - 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]** Responsive Images (srcset) — 55 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]** Mobile Sticky CTA — Add-to-cart button found but no sticky/fixed positioning detected
  - Fix: Add a sticky add-to-cart bar at the bottom of mobile screens. Use position: sticky or position: fixed with bottom: 0. The CTA should always be visible without scrolling.
  - Evidence: HTML-heuristic
- **[WARN]** Text Overflow Handling — No word-break/overflow-wrap CSS detected
  - Fix: Add 'overflow-wrap: break-word' to your body or main content container. Without it, long URLs, product SKUs, or German compound words can break mobile layouts.
  - Evidence: HTML-heuristic
- **[WARN]** Print Stylesheet — Order/invoice page without print styles
  - Fix: Add @media print CSS rules to hide navigation, ads, and non-essential elements. Ensure order details, prices, and company info are visible when printed.
  - Evidence: HTML-heuristic
- **[WARN]** Heading Hierarchy (WCAG 1.3.1) — Skipped levels: h2→h4
  - Fix: Keep headings in order h1 → h2 → h3 → h4 with no skipped levels. Screen readers use the heading hierarchy to navigate. If you want smaller text at the same level, use a CSS class rather than a lower heading tag.
  - Evidence: HTML-heuristic
- **[WARN]** Link Text Quality (WCAG 2.4.4) — 9 links have generic text ("click here", "more", "here"...)
  - Fix: Replace 'Click here' and 'Read more' with descriptive text: 'Read more about GDPR', 'See module pricing'. Screen readers read links out of context, so a bare 'more' carries no meaning.
  - Evidence: HTML-heuristic
- **[INFO]** Payment Methods Detected — No known payment gateway detected on the homepage
  - Evidence: HTML-heuristic
- **[INFO]** Express Checkout (Apple Pay + Google Pay) — Apple Pay / Google Pay not detected on the homepage — express checkout usually appears only in the cart or checkout
  - Evidence: HTML-heuristic
- **[INFO]** SK/CZ Local Payment Methods — No SK/CZ local payment method detected on the homepage — bank buttons and QR payment usually appear only in checkout
  - Evidence: HTML-heuristic
- **[PASS]** Viewport Configuration — width=device-width, initial-scale=1
  - Evidence: HTML-heuristic
- **[PASS]** Content Fits Viewport — No horizontal scrolling needed
  - Evidence: HTML-heuristic
- **[PASS]** Responsive Design Techniques — Media queries detected
  - Evidence: HTML-heuristic
- **[PASS]** Mobile Navigation (Semantic) — <nav> element present — proper navigation landmark
  - Evidence: HTML-heuristic
- **[PASS]** Form Input Types — Optimized: 2 email, 1 search
  - Evidence: HTML-heuristic
- **[PASS]** Form Input Labels (WCAG 3.3.2) — 8/8 inputs have a label
  - Evidence: HTML-heuristic

### AI Readiness — 64/100

- **[FAIL]** Image Alt Text Quality for AI — Only 48% quality alt text — 1 missing, 20 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]** Structured Data Foundation — Only 1 distinct schema type (BusinessEntity) — insufficient for AI visibility
  - Fix: One schema type is not enough. Add at minimum: Organization (identity), Product (commerce), BreadcrumbList (navigation), WebSite+SearchAction (discoverability), FAQPage (Q&A answering).
  - Evidence: schema
- **[WARN]** Organization Schema + Entity Linking — Organization schema found but no sameAs links
  - Fix: Add sameAs array to your Organization schema linking to Wikipedia, LinkedIn, Facebook, Instagram, and other official profiles. This creates a Knowledge Graph entity for your brand.
  - Evidence: schema
- **[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]** Structured Content (Lists & Tables) — 23 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]** Content Freshness Signals — Visible date found but not in structured data
  - Fix: Add both: 1) dateModified and datePublished in your Article/Product JSON-LD schema, 2) A visible 'Last updated: [date]' on the page. Both signals reinforce content freshness for AI.
  - Evidence: HTML-heuristic
- **[WARN]** Entity Clarity & Brand Signals — OG tags complete but no sameAs entity links
  - Fix: For full entity clarity: 1) Complete Open Graph tags (og:title, og:description, og:image, og:type), 2) Add sameAs in Organization schema linking to Wikipedia, LinkedIn, Facebook, and other profiles.
  - 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: Generate a Heureka XML feed at /feed/heureka.xml (or /export/heureka.xml). PrestaShop has a Heureka.cz module, WooCommerce has plugins. Structure: <SHOP><SHOPITEM>...</SHOPITEM></SHOP> with ITEM_ID/PRODUCTNAME/URL/PRICE_VAT/CATEGORYTEXT (required) + EAN/PARAM/DELIVERY_DATE (highly recommended for ranking).
  - Evidence: file-probe
- **[WARN]** Extractable Answer Blocks — 11 paragraphs, avg 18 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: 153 words — only 9% 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]** Canonical Tag for AI Deduplication — Canonical points to different URL: https://www.elstrote.sk/
  - Fix: Verify this canonical is intentional. AI models cluster near-duplicate URLs and choose one representative page. If canonical points to a different URL, AI will only index that target URL, not this page.
  - 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 — 2/4 signals — missing: @id in JSON-LD, sameAs links (Wikipedia, LinkedIn)
  - Fix: Add: @id in JSON-LD, sameAs links (Wikipedia, LinkedIn). 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]** Trust Widget — No trust widget (Heureka / Trustpilot / AggregateRating) detected
  - Fix: For SK/CZ shops: install the Heureka Ověřeno zákazníky widget (free for verified sellers — https://sluzby.heureka.sk). Alternatives: Trustpilot, Google Reviews with AggregateRating schema. Place the trust widget on product + category + 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, which this single-URL scan didn't visit
  - Evidence: schema
- **[INFO]** Search Typo Handling (measurement) — A correctly spelled query and the same query with a typo return similarly sized pages (181004 B vs 182576 B) — consistent with typo tolerance
  - Evidence: HTML-heuristic · 182824 B response · https://elstrote.sk/action/ProductSearch/prepareString/?string=xyzqwerty-nezmysel · confidence: low
- **[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 — 63/100 — partly ready (Access 100 · Understand 50 · Discover 50 · Transact 50)
- **[INFO]** Agent: Access — can an agent get in — 100/100 (2 signals)
- **[INFO]** Agent: Understand — can it read the products — 50/100 (2 signals)
- **[INFO]** Agent: Discover — can it find the whole catalogue — 50/100 (3 signals)
- **[INFO]** Agent: Transact — can it act (cart, terms) — 50/100 (3 signals)
- **[PASS]** AI Bot Access Policy — No AI bot restrictions (allowed by default)
  - Evidence: file-probe
- **[PASS]** AI agent access (live) — ChatGPT-User and PerplexityBot get the same page as a browser
  - Evidence: file-probe · ChatGPT-User, PerplexityBot: same page as a browser · https://elstrote.sk
- **[PASS]** Content Accessibility for AI — 1224 words in raw HTML (5.2% text ratio) — readable by AI crawlers without executing JS
  - Evidence: HTML-heuristic
- **[PASS]** Zero-results Recovery — A search with no matches still offers products, suggestions or a way to get help
  - Evidence: HTML-heuristic · 182824 B response · https://elstrote.sk/action/ProductSearch/prepareString/?string=xyzqwerty-nezmysel · confidence: low
- **[PASS]** Content Depth for AI — 1224 words — rich content for AI analysis and citation
  - Evidence: HTML-heuristic
- **[PASS]** Heading Hierarchy for AI — Proper structure: 1 H1 → 7 H2s → 11 H3s — clear content outline
  - Evidence: HTML-heuristic
- **[PASS]** Semantic HTML Structure — 4/6 semantic elements: <nav>, <main>, <header>, <footer>
  - Evidence: HTML-heuristic
- **[PASS]** Common Question Coverage — Answers 4/5 key shopper questions: price, shipping, returns/refunds, payment
  - Evidence: HTML-heuristic
- **[PASS]** Internal Link Density — 47 contextual internal links per 1,000 words — strong knowledge graph signal
  - Evidence: HTML-heuristic
- **[PASS]** Content-to-Boilerplate Ratio — 60% of text in <main>/<article> — clean content signal
  - Evidence: HTML-heuristic

### GDPR — 65/100

- **[FAIL]** Privacy Policy Page
  - Fix: Create a comprehensive privacy policy covering: what data you collect, why (legal basis), how long you store it, who you share it with, and how users can exercise their GDPR rights (access, deletion, portability).
  - Evidence: HTML-heuristic
- **[FAIL]** Consumer Dispute Resolution Links — No EU ODR platform or supervisory-authority link found

### Vulnerability — 59/100

- **[FAIL]** Known Vulnerabilities (CVE) — 5 CVEs associated with 1 detected component version
  - Fix: Update jQuery 1.11.3 → 3.7.1 (CVE-2011-4969, CVE-2012-6708, CVE-2015-9251, CVE-2020-11022, CVE-2020-11023). Verify each before acting — a host or distro can backport a security patch while the version string still reads as vulnerable, so a detected CVE is not proof your install is affected. CVE details: CVE-2011-4969: https://nvd.nist.gov/vuln/detail/CVE-2011-4969 · CVE-2012-6708: https://nvd.nist.gov/vuln/detail/CVE-2012-6708 · CVE-2015-9251: https://nvd.nist.gov/vuln/detail/CVE-2015-9251 · CVE-2020-11022: https://nvd.nist.gov/vuln/detail/CVE-2020-11022 · CVE-2020-11023: https://nvd.nist.gov/vuln/detail/CVE-2020-11023
  - Evidence: file-probe · confidence: low
- **[FAIL]** Admin Panel at Default URL — Accessible at: /admin
  - Fix: Rename your admin directory to a random, non-guessable path (e.g., /admin-x7k9m2). Add IP whitelisting via .htaccess, implement 2FA, and set up brute-force protection (fail2ban or similar).
  - Evidence: file-probe
- **[FAIL]** jQuery Version — jQuery 1.11.3 — critically outdated!
  - Fix: jQuery 1.11.3 is associated with multiple known security vulnerabilities. Upgrade to 3.7.x. If your plugins require jQuery 1.x/2.x, use jquery-migrate as a temporary bridge.
