## Detailed findings

### Performance — 81/100

- **[FAIL]** Total Page Weight — 6.6 MB, 62 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]** Script Loading Strategy — Only 0% of 1 scripts optimized — most are render-blocking
  - Fix: Add defer or async to all <script src='...'> tags. Render-blocking scripts are a leading cause of slow FCP. Defer maintains execution order, async does not.
  - Evidence: HTML-heuristic
- **[WARN]** Largest Contentful Paint (LCP) — 2.89s (good: <2.5s) — Core Web Vital
  - Fix: Optimize your largest element (usually hero image or product image): preload it with <link rel='preload'>, use WebP/AVIF format, set explicit width/height, and serve from CDN.
  - Evidence: PSI-lab
- **[WARN]** Unused Code (CSS + JS) — 170 KB unused (CSS: 62 KB, JS: 108 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]** Cache-Control Strategy — no-store, no-cache, must-revalidate
  - 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
- **[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

- **[PASS]** Cumulative Layout Shift (CLS) — 0.002 — Core Web Vital ✓
  - Evidence: PSI-lab
- **[PASS]** Speed Index — 1.67s
  - Evidence: PSI-lab
- **[PASS]** JavaScript Budget — 170 KB — within the 600 KB budget
  - Evidence: PSI-lab · 170 KB JavaScript · confidence: high
- **[PASS]** Request Budget — 62 requests — within the budget of 80
  - Evidence: PSI-lab · 62 requests · confidence: high
- **[PASS]** Text Compression (gzip/brotli) — All text resources properly compressed
  - Evidence: HTTP-header
- **[PASS]** Resource Hints (Preload/Preconnect) — 3 preload, 0 preconnect hint(s)
  - Evidence: HTML-heuristic
- **[PASS]** Lazy Loading — 51% of images use native lazy loading (39/77)
  - Evidence: HTML-heuristic
- **[PASS]** Font Loading Strategy — font-display: swap
  - Evidence: HTML-heuristic
- **[PASS]** HTTP/3 (QUIC) Support — HTTP/3 enabled via Alt-Svc header

  - Evidence: HTML-heuristic
- **[PASS]** Critical CSS Strategy — Critical CSS / async CSS loading detected
  - Evidence: PSI-lab

### SEO — 87/100

- **[FAIL]** Canonical URL
  - Fix: Add a <link rel='canonical'> tag pointing to the preferred URL on every page. This is critical for stores with URL parameters (?sort=, ?page=, ?filter=).
  - 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 Format Optimization — 0% next-gen formats — 71 JPEG, 6 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]** Deep Heading Hierarchy — No H3 subheadings for long content
  - Fix: Add H3 subheadings under your H2 sections to create a deeper content hierarchy. This helps search engines understand sub-topics and improves featured snippet eligibility.
  - Evidence: HTML-heuristic
- **[WARN]** Empty/Dead Links — 40 dead links (0 empty, 40 hash-only, 0 javascript:void)
  - Fix: Replace empty href='', href='#', and href='javascript:void(0)' with actual URLs. If interactive, use <button> instead of <a>.
  - Evidence: HTML-heuristic
- **[INFO]** Text-to-HTML Ratio — 5% ratio but 2348 words — content is substantial; the low ratio is markup/inline-JS bloat, not thin content
  - Evidence: HTML-heuristic
- **[PASS]** Meta Title — 50 chars — "KAJO.sk - náradie pre vašu dielňu, stavbu, záhradu"
  - Evidence: HTML-heuristic
- **[PASS]** Meta Description — 149 chars
  - Evidence: HTML-heuristic
- **[PASS]** H1 Heading — "Vítame Vás na internetovom obchode Kajo.sk"
  - Evidence: HTML-heuristic

- **[PASS]** Content Depth — 2348 words — sufficient content
  - Evidence: HTML-heuristic
- **[PASS]** Internal Linking — 512 internal links — strong site navigation
  - Evidence: HTML-heuristic

  - Evidence: HTML-heuristic
- **[PASS]** Sitemap Freshness — Newest <lastmod> 36 day(s) ago
  - Evidence: HTML-heuristic

### Security — 75/100

- **[FAIL]** HSTS (Strict-Transport-Security)
  - Fix: Add header: Strict-Transport-Security: max-age=31536000; includeSubDomains; preload — then submit to hstspreload.org.
  - Evidence: HTTP-header
- **[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]** 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]** 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
- **[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]** HTTP → HTTPS Redirect — HTTP properly redirects to HTTPS
  - Evidence: HTTP-header
- **[PASS]** Content-Security-Policy (CSP) — Present and reasonably configured
  - Evidence: HTTP-header
- **[PASS]** Clickjacking Protection — X-Frame-Options: sameorigin
  - Evidence: HTTP-header
- **[PASS]** Cookie Security Flags — 1 cookie(s) — all have Secure, HttpOnly, SameSite
  - Evidence: HTTP-header
- **[PASS]** Technology Disclosure — Server: cloudflare (no version)
  - Evidence: HTTP-header
- **[PASS]** Subresource Integrity (SRI) — No SRI-eligible third-party scripts loaded
  - Evidence: HTML-heuristic
- **[PASS]** CDN / WAF Protection — Cloudflare detected — DDoS protection and edge caching active
  - Evidence: HTTP-header

### Mobile — 76/100

- **[FAIL]** Form Input Labels (WCAG 3.3.2) — Only 5/44 inputs have a label (11%)
  - Fix: 39 input elements have no label. Every input needs a matching <label for="id">Text</label> or an aria-label. A placeholder is NOT a label (WCAG 3.3.2). On a checkout or registration form this costs conversion and breaches EN 301 549 (EAA 2026).
  - Evidence: HTML-heuristic
- **[WARN]** Mobile Performance Score — 81/100 (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]** 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) — 77 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]** 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
- **[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: 1 email
  - Evidence: HTML-heuristic
- **[PASS]** Heading Hierarchy (WCAG 1.3.1) — No skipped heading levels
  - Evidence: HTML-heuristic
- **[PASS]** Link Text Quality (WCAG 2.4.4) — All links have descriptive text
  - Evidence: HTML-heuristic

### AI Readiness — 65/100

- **[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]** Canonical Tag for AI Deduplication
  - Fix: Add <link rel='canonical' href='https://your-absolute-url'> to every page. This tells AI engines which URL is the authoritative version of this content.
  - Evidence: HTML-heuristic
- **[WARN]** Structured Data Foundation — 3 distinct schema types (BusinessEntity, WebPage, WebSite) — add more for comprehensive AI coverage
  - Fix: Expand your structured data with genuinely different types: Organization, Product, BreadcrumbList, WebSite with SearchAction, and FAQPage. Adding synonyms of the same entity (Store + LocalBusiness + Organization) does not help — variety of meaning does.
  - 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]** Heading Hierarchy for AI — Good: 1 H1 + 59 H2s, but no H3 subsections
  - Fix: Add H3 subheadings under your H2 sections for deeper content structure. AI models use heading hierarchy as a table of contents to navigate and extract information.
  - Evidence: HTML-heuristic
- **[WARN]** Structured Content (Lists & Tables) — 108 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]** 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 — 35 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 — No statistical data found in content
  - Fix: Add numbers: pricing comparisons, performance metrics, customer statistics, industry benchmarks. Specific data (e.g., '99.9% uptime', '4.8/5 rating from 2,400 reviews') is what AI quotes most.
  - Evidence: HTML-heuristic
- **[WARN]** Section Length Optimization — Avg section: 27 words — only 0% 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: shipping, 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, consistent brand name (title/schema/OG), sameAs links (Wikipedia, LinkedIn)
  - Fix: Add: @id in JSON-LD, consistent brand name (title/schema/OG), 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 20 — 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 (199362 B vs 199362 B) — consistent with typo tolerance
  - Evidence: HTML-heuristic · 199362 B response · https://www.kajo.sk/vyhladavanie?search_query=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 — 71/100 — partly ready (Access 100 · Understand 50 · Discover 83 · Transact 50)

- **[PASS]** Content Accessibility for AI — 2348 words in raw HTML (4.9% 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 · 199362 B response · https://www.kajo.sk/vyhladavanie?search_query=xyzqwerty-nezmysel · confidence: low
- **[PASS]** Site Search Schema (SearchAction) — WebSite SearchAction configured — AI can search your store

  - Evidence: HTML-heuristic

### GDPR — 62/100

- **[FAIL]** Cookie Consent Banner (CMP)
  - Fix: Install a certified consent management platform: Cookiebot, OneTrust, Usercentrics, or CookieYes. The CMP must block ALL non-essential cookies and scripts until explicit consent is given (opt-in, not opt-out).
  - Evidence: HTML-heuristic
- **[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]** Legal Contact / Imprint Page
  - Fix: Add an imprint/about-us page with: company name, registered address, contact email, VAT number, and trade register info. In Germany/Austria/Switzerland this is legally required (Impressumspflicht).
  - Evidence: HTML-heuristic
- **[WARN]** Right to Erasure (Data Deletion)
  - Fix: Provide a clear mechanism for users to request data deletion — either a dedicated page, a form, or explicit instructions in your privacy policy. Include a 'Delete my account' option in user settings.
  - 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
- **[WARN]** Data Protection Officer Contact
  - Fix: Add DPO contact details (or privacy contact if DPO not required) to your privacy policy and footer. Include: name/title, email (e.g., dpo@yourdomain.com), and postal address.
  - Evidence: HTML-heuristic
- **[WARN]** Withdrawal of Consent Mechanism
  - Fix: Provide a clear way to withdraw consent: an 'unsubscribe' link in emails, a 'cookie settings' button in the footer, and a 'revoke consent' section in your privacy policy.
  - Evidence: HTML-heuristic
- **[WARN]** Omnibus Price Disclosure (30-day low) — Discounts shown without a visible 'lowest price in last 30 days' reference
  - Fix: Whenever you advertise a price reduction, display the lowest price applied in the 30 days before the discount, next to the new price. In PrestaShop add a 30-day price-history anchor (e.g. our zu_pricehistory module) so every sale label is compliant automatically.
  - Evidence: HTML-heuristic · confidence: low
- **[INFO]** Online Withdrawal Function — No explicit online withdrawal button in the server HTML — it may live in the logged-in account/order area, which this scan can't reach. Verify it's present.
  - Evidence: HTML-heuristic · confidence: low
- **[INFO]** Legal guarantee notice — No harmonised notice on the legal guarantee was found on the pages we scanned — it may be on a page this scan does not open. Verify it is shown.
  - Evidence: HTML-heuristic · confidence: low
- **[PASS]** Tracking Scripts & Consent — No tracking scripts detected

  - Evidence: HTML-heuristic

### Vulnerability — 91/100

- **[FAIL]** Form CSRF Protection — 41 form(s) without CSRF tokens
