Prečo je to dôležité: llms.txt is the emerging standard for AI-readable site descriptions — like robots.txt was for search engines. Early adopters (Yoast, Cloudflare, Stripe) are already using it. Without it, AI assistants have no guided overview of your store.
Ako opraviť: Create /llms.txt in Markdown format:
# Your Store Name
> One-line summary of your business and key offerings.
Detailed description paragraph.
## Products
- [Product Category](URL): Description
## About
- [About Us](URL): Company history and values
See llmstxt.org for the full specification.
0 H1, 4 H2, 7 H3 — poor structure
Prečo je to dôležité: AI extracts information based on heading structure. Pages with proper H1→H2→H3 hierarchy are more accurately parsed by ChatGPT, Perplexity, and Google AI Overviews. Without it, AI may misinterpret your content.
Ako opraviť: 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).
Prečo je to dôležité: No freshness signals = AI assumes your content is stale. ChatGPT and Perplexity both weight recency in their citation algorithms. Competitors who show recent updates will be cited instead of your static pages.
Ako opraviť: 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.
Only 11% quality alt text — 217 missing, 54 poor
Prečo je to dôležité: Poor alt text means your product images are invisible to AI visual search (Google Lens, Bing Visual Search). This is also an accessibility requirement (WCAG 2.1 AA) — many regions enforce this legally.
Ako opraviť: 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.
Prečo je to dôležité: llms-full.txt provides AI models with your entire site content in one parseable file. It's the difference between an AI having a brief overview vs. deep knowledge of your products and services.
Ako opraviť: Create /llms-full.txt containing your complete site documentation in a single Markdown file — product catalog summaries, FAQs, policies, brand story. This gives AI models maximum context about your store.
3 schema types found (WebSite, Organization, SearchAction) — add more for comprehensive AI coverage
Prečo je to dôležité: AI assistants (ChatGPT, Perplexity, Google AI Overviews) synthesize answers from structured data. Research shows sites with comprehensive schema markup are 36% more likely to be cited by AI.
Ako opraviť: Expand your structured data: add Organization, Product, BreadcrumbList, WebSite with SearchAction, and FAQPage schemas. Sites with 4+ schema types are 36% more likely to appear in AI search summaries.
Organization schema found but no sameAs links
Prečo je to dôležité: sameAs links tell AI: 'This is the same entity across the web.' Sites with sameAs to Wikipedia are 3x more likely to appear in AI-generated answers. It's how Google builds Knowledge Panels.
Ako opraviť: 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.
Prečo je to dôležité: FAQ schema provides 30% higher AI citation rates (LLMClicks research). ChatGPT, Perplexity, and Google AI Overviews pull FAQ answers verbatim. It's the fastest way to get your content cited by AI.
Ako opraviť: 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).
Prečo je to dôležité: AI assistants use breadcrumbs to understand product categorization and site structure. Without it, AI can't contextualize where products fit in your catalog — e.g., 'Running Shoes' under 'Sports > Footwear > Running'.
Ako opraviť: Add BreadcrumbList schema reflecting your category hierarchy: Home → Category → Subcategory → Product. Each item needs name and URL.
3/6 elements — missing: <article>, <nav>, <aside>
Prečo je to dôležité: AI crawlers don't see your CSS. They rely on semantic HTML to distinguish main content from navigation, ads, and boilerplate. The WordLift AI Audit weights semantic HTML as a primary machine-readability signal.
Ako opraviť: Add: <article>, <nav>, <aside>. Semantic HTML tells AI what's content (<article>), navigation (<nav>), sidebar (<aside>), etc. — without relying on CSS classes or visual layout.
No structured content elements found
Prečo je to dôležité: Unstructured paragraph-only content is harder for AI to parse and cite. Pages with lists and tables get cited 30-40% more in AI-generated answers because AI can extract specific facts more reliably.
Ako opraviť: Add bulleted lists for features/benefits, numbered lists for steps/rankings, and tables for comparisons/specifications. These are the content formats AI extracts most reliably.
OG tags complete but no sameAs entity links
Prečo je to dôležité: AI needs to confidently identify your brand entity. Open Graph + sameAs create a cross-platform identity that AI models recognize. The HubSpot AEO Grader found entity clarity is a top-3 factor for AI brand recognition.
Ako opraviť: 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.
Prečo je to dôležité: AI models weight author expertise heavily. Pages from identified experts get cited 3x more than anonymous content. This is especially important for product guides, reviews, and advice content.
Ako opraviť: 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.
Prečo je to dôležité: ai-plugin.json enables AI agents to interact with your store programmatically — search products, check prices, process orders. This is the bridge between AI assistants and your e-commerce functionality.
Ako opraviť: Create /.well-known/ai-plugin.json if you have an API. This enables direct AI agent integration (ChatGPT Actions, custom GPTs). Include: name_for_model, description_for_model, auth config, and link to OpenAPI spec.
Prečo je to dôležité: Product feeds power Google Shopping, Bing Shopping, and increasingly AI commerce. Without a structured product feed, AI agents can't efficiently index your full catalog for product recommendations.
Ako opraviť: 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.
Prečo je to dôležité: Heureka.sk a Heureka.cz sú dominantné cenové porovnávače na SK/CZ trhu (40%+ all e-com discovery traffic). Bez XML feedu nie ste viditeľní na hlavnom trhovisku — strata 20-30 % potenciálneho traffic. Žiaden generický audit tool toto nekontroluje.
Ako opraviť: 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).
Prečo je to dôležité: Voice AI commerce is growing rapidly. SpeakableSpecification tells voice assistants which content to read aloud. Early adoption positions your store for the voice shopping wave.
Ako opraviť: Add SpeakableSpecification schema to identify content sections suitable for voice assistants (Google Assistant, Alexa, Siri). Mark your product summaries and FAQs as speakable.
5 paragraphs, avg 151 words — too long for AI snippets
Prečo je to dôležité: Pages with 40-80 word paragraphs earn 70% more AI citations (Otterly 2026 data). AI extracts individual paragraphs as answer snippets — dense walls of text get skipped.
Ako opraviť: 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.
Avg section: 203 words — only 0% in 80-200 word optimal range
Prečo je to dôležité: Pages with 120-180 word sections earn 70% more AI citations (Otterly Citation Economy 2026). For Google AI Overviews specifically, 100-150 words per section is the sweet spot.
Ako opraviť: 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.
Prečo je to dôležité: Q&A content format matches how people query AI assistants. Without question-format headings, your content is harder for AI to map to user queries.
Ako opraviť: 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.
Canonical points to different URL: https://www.lunys.sk/
Prečo je to dôležité: AI search engines (ChatGPT, Perplexity, Bing Copilot) use canonicals to deduplicate content. A wrong canonical means AI may cite the wrong page version or ignore this page entirely.
Ako opraviť: 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.
Prečo je to dôležité: AI shopping agents (Google Shopping, ChatGPT, Bing Copilot) filter by return flexibility. Products with return policy schema get priority placement in AI product comparisons.
Ako opraviť: Add MerchantReturnPolicy schema with: returnPolicyCategory (e.g., MerchantReturnFiniteReturnWindow), merchantReturnDays, returnMethod, returnFees. Link it from Product/Offer via hasMerchantReturnPolicy.
Prečo je to dôležité: Fulfillment speed now factors into AI product recommendations. Complete shipping schema means AI can show 'Free shipping, delivers in 2-3 days' — a massive conversion driver.
Ako opraviť: Add OfferShippingDetails schema with: shippingRate, shippingDestination, deliveryTime (handlingTime + transitTime). AI agents deprioritize products without shipping info.
2/4 signals — missing: @id in JSON-LD, sameAs links (Wikipedia, LinkedIn)
Prečo je to dôležité: Brands with verified Knowledge Graph presence receive 3.1x more AI citations. @id creates a persistent entity identifier that connects your schema across pages and platforms.
Ako opraviť: 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.
Grade 20 — too complex for broad AI citation (technical threshold: 14)
Prečo je to dôležité: Content above grade 12 readability is harder for AI to extract as clear, concise answers. Pages using clear headers and approachable language are 28% more likely to be cited by AI.
Ako opraviť: 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.
Prečo je to dôležité: Content without citations or expert quotes appears unverified to AI. AI assistants prefer content backed by named sources, data references, and expert opinions.
Ako opraviť: 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).
Prečo je to dôležité: ai.txt is an emerging standard (proposed May 2025) for fine-grained AI permissions beyond robots.txt. Early adoption signals AI-forward thinking and gives you control over how AI uses your content.
Ako opraviť: Create /ai.txt or /.well-known/ai.txt to declare granular AI permissions per content type: which AI actions (summarization, training, extraction) are allowed for which content sections.
Prečo je to dôležité: WebMCP is called 'the new Schema.org moment' — it's how AI agents will interact with your store (search products, add to cart, check availability). Google and Microsoft are co-developing this standard.
Ako opraviť: 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.
38% in main content area — too much boilerplate
Prečo je to dôležité: AI crawlers specifically target <main> and <article> content blocks. If most of your text is in navigation, footers, and sidebars, AI gets noise instead of signal — reducing citation quality.
Ako opraviť: Move more content into <main> or <article> elements. Reduce navigation text, footer content, and sidebar noise. AI crawlers extract content from semantic containers and discard the rest.
1 source: Heureka Ověřeno
Prečo je to dôležité: Without a second review source and a machine-readable reviewCount, AI assistants can't verify scale of social proof — single-source ratings are routinely deweighted as potentially curated.
Ako opraviť: Single review source detected without published reviewCount. Add AggregateRating JSON-LD (ratingValue + reviewCount + bestRating) so the count is machine-readable, and add a second source (Heureka Ověřeno + Trustpilot is the SK/CZ standard).
No AI bot restrictions (allowed by default)
2719 words in raw HTML (3.8% text ratio) — readable by AI crawlers without executing JS
WebSite SearchAction configured — AI can search your store
2719 words — rich content for AI analysis and citation
First paragraph: 722 words — good content density above the fold
30 data points found — strong citation magnet
28 contextual internal links per 1,000 words — strong knowledge graph signal
Heureka trust widget detected
Prečo je to dôležité: Heureka Ověřeno is the dominant SK/CZ social-proof program — buyers trust it 2× more than generic ratings. Verified shops with a public obchody.heureka.* profile show stronger long-term provenance than just a widget script.
No Product schema on this homepage — Product schema lives on product detail pages, which this single-URL scan didn't visit
Prečo je to dôležité: Product schema only belongs on product pages, so its absence on this page is expected — not a defect. Scan a product URL to evaluate it.
Ako opraviť: To audit Product schema, run the scan on a product detail URL. On product pages add: name, description, image, offers (price, priceCurrency, availability), brand, sku, aggregateRating.
No review schema on this homepage — review/rating schema typically lives on product pages
Prečo je to dôležité: Review schema is product-page-specific, so its absence here is expected, not a defect.
Ako opraviť: Scan a product URL to audit review schema. On product pages add AggregateRating (ratingValue, reviewCount, bestRating) and individual Review schemas.
