AI verdict

Your site has solid foundations, but security needs immediate attention. Prioritize enabling HTTPS with HSTS protection to safeguard customers. Your excellent SEO and accessibility give you a competitive edge.

Not subject to NIS2 cybersecurity duties.Based on NACE sector + company size, Article 21 compliance is not mandatory. Security best practices still recommended.

Supplying a NIS2-regulated company?Even outside direct scope you may inherit supply-chain duties — regulated companies cascade them to suppliers by contract (security, incident reporting, encryption). ICT and managed-service providers are in scope regardless of size.

Check supplier obligations ·Legal basis: NIS2 Art. 21 · SK 366/2024 §21 · NIS2 Art. 21(2)(d)

Possible IČO mismatch

The IČO in your site footer (36033553) differs from the IČO our autocomplete found for the domain (57559066). Often a copy-pasted template footer or a recent legal entity change — verify the IČO in your footer matches your actual operating entity. Informational only, doesn't affect score.

What we found: 276 KB wasted on unused code!

Why it matters: Over 200 KB of unused code significantly slows parsing and execution. This is one of the easiest performance wins — removing dead code requires no trade-offs.

Note: This check uses heuristic detection and may produce false positives. Manual verification recommended.

How to fix: You're loading 276 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· Confidence: low

What we found: 0.111 (good: <0.1) — Core Web Vital

Why it matters: Layout shifts cause mis-clicks — users tap 'Buy' but the page shifts and they hit 'Remove' instead. CLS is a Core Web Vital directly impacting Google rankings.

How to 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· Confidence: high

Request quote for speed audit

What we found: 2.0 MB, 76 requests (optimal: <1.5 MB, <50 req)

Why it matters: A 3 MB page takes 6+ seconds on 3G mobile. Most e-commerce traffic is mobile — heavy pages lose customers on poor connections.

How to 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· Confidence: high

Request quote for speed audit

What we found: no-store, no-cache, must-revalidate, no-cache, private

Why it matters: no-cache/no-store forces browsers to re-download resources on every visit. Repeat visitors load your entire site from scratch every time.

How to 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· Confidence: high

Request quote for speed audit

What we found: Only 57% of 7 scripts use async/defer

Why it matters: Synchronous scripts block HTML parsing — the browser stops rendering until each script downloads and executes. Async/defer allows parallel downloading without blocking.

How to 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· Confidence: high

What we found: Custom fonts detected without preload hints

Why it matters: Fonts are discovered late in the render pipeline (after CSS is parsed). Preloading tells the browser to download them immediately, reducing Flash of Invisible Text (FOIT) by 200-500ms.

How to 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.

Critical findings

Unused Code (CSS + JS)· Performance

Over 200 KB of unused code significantly slows parsing and execution. This is one of the easiest performance wins — removing dead code requires no trade-offs.

HSTS (Strict-Transport-Security)· Security

Without HSTS, attackers can intercept the first HTTP request and downgrade the connection to steal session cookies on public WiFi.

Content-Security-Policy (CSP)· Security

CSP is a strong defense against XSS attacks. Without it, any injected script runs with full privileges. CSP blocks inline script injection.

Link Text Quality (WCAG 2.4.4)· Mobile

An excessive share of vague links breaches WCAG 2.4.4 (accessibility) and SEO best practice (Google uses anchor text to understand the target page). An EAA 2026 compliance risk.

Content Freshness Signals· AI Readiness

With 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.

Consumer Dispute Resolution Links· Legal & Compliance

EU Regulation 524/2013 makes the ODR link mandatory for every online trader; national law requires naming the supervisory authority. ŠOI/ČOI inspect for exactly this, and its absence is a common consumer-law breach.

Known Vulnerabilities (CVE)· Vulnerability

Versions with published CVEs are a prime automated-scanner target — bots (Shodan, Greynoise, Mirai-family) probe for them within minutes. This finding is inferred from the detected version, so confirm the component is actually unpatched before treating it as exploitable.

Admin Panel at Default URL· Vulnerability

Default admin URLs receive thousands of automated brute-force attempts daily. Botnets target /admin, /wp-admin, /administrator relentlessly. A renamed path blocks 99% of automated attacks.

jQuery Version· Vulnerability

jQuery 1.x is associated with 6+ known CVEs including XSS and prototype pollution. Automated scanners specifically target sites with jQuery <3.0.

DMARC Policy (Email Auth)· Vulnerability

Without DMARC, attackers can send perfectly spoofed emails as your brand. Since May 2025, Google, Yahoo, and Microsoft require DMARC for bulk senders. Missing DMARC = email deliverability problems.

Payment Page Security· Vulnerability

Payment pages without proper security headers violate PCI DSS and make card data theft significantly easier. Payment processors can impose monthly fines for non-compliance.

How to fix: You're loading 276 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.

Cumulative Layout Shift (CLS)Warning

0.111 (good: <0.1) — Core Web Vital

Why it matters: Layout shifts cause mis-clicks — users tap 'Buy' but the page shifts and they hit 'Remove' instead. CLS is a Core Web Vital directly impacting Google rankings.

How to 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).

Total Page WeightWarning

2.0 MB, 76 requests (optimal: <1.5 MB, <50 req)

Why it matters: A 3 MB page takes 6+ seconds on 3G mobile. Most e-commerce traffic is mobile — heavy pages lose customers on poor connections.

How to 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.

Cache-Control StrategyWarning

no-store, no-cache, must-revalidate, no-cache, private

Why it matters: no-cache/no-store forces browsers to re-download resources on every visit. Repeat visitors load your entire site from scratch every time.

How to 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.

Why it matters: Fonts are discovered late in the render pipeline (after CSS is parsed). Preloading tells the browser to download them immediately, reducing Flash of Invisible Text (FOIT) by 200-500ms.

How to 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.

JavaScript BudgetPassed

428 KB — within the 600 KB budget

Why it matters: JavaScript is the most expensive resource on a page: it must be downloaded, parsed and executed before the page responds to input. Staying under 600 KB is what keeps mid-range phones responsive.

Request BudgetPassed

76 requests — within the budget of 80

Why it matters: Every request costs a round trip. Under HTTP/2 they share a connection, but each still has to be discovered, queued and parsed.

Text Compression (gzip/brotli)Passed

All text resources properly compressed

Resource Hints (Preload/Preconnect)Passed

1 preload, 3 preconnect hint(s)

Lazy LoadingPassed

5% of images use native lazy loading (4/76)

Third-party ServicesInfo

Not measured — PageSpeed did not return the third-party audit for this URL

Why it matters: We report this as unmeasured rather than as zero third parties, because those are very different findings.

How to fix: Re-run the scan, or check the third-party summary directly at PageSpeed Insights.

Render-blocking ResourcesInfo

Not measured — PageSpeed did not return the render-blocking audit for this URL

How to fix: Re-run the scan, or test directly at PageSpeed Insights. This metric needs a successful Lighthouse lab run.

SEO

95/100

Weight: 20% · 22 OK · 3 warnings · 0 failures · 26 total

Twitter/X CardsWarning

Why it matters: Twitter Cards make your links stand out in X/Twitter feeds. Without them, shared links appear as plain text URLs.

How to fix: Add <meta name='twitter:card' content='summary_large_image'>, twitter:title, and twitter:image tags.

Image Format OptimizationWarning

0% next-gen formats — 3 JPEG, 2 PNG images

Why it matters: Your images use legacy formats only. Switching to WebP typically reduces page weight by 30-50% — one of the highest-impact performance optimizations.

How to fix: Convert all images to WebP format. Most CMS platforms have plugins for automatic WebP conversion. Use AVIF for even better compression.

Canonical URL ConsistencyWarning

Canonical points to different URL: https://www.drevostav.sk/

Why it matters: A mismatched canonical tells Google this page is a duplicate of another URL. If unintentional, Google may ignore this page entirely in favor of the canonical target.

How to 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.

Text-to-HTML RatioInfo

6% ratio but 2289 words — content is substantial; the low ratio is markup/inline-JS bloat, not thin content

Why it matters: Text-to-HTML ratio is only a thin-content signal when actual word count is also low. With 500+ words, search engines have plenty to rank on.

How to fix: Your text content is sufficient. To raise the ratio, move inline <script>/<style> to external files and trim template bloat — this is a performance/cleanliness win, not a content gap.

Security

57/100

Weight: 15% · 7 OK · 8 warnings · 2 failures · 18 total

HSTS (Strict-Transport-Security)Failed

Why it matters: Without HSTS, attackers can intercept the first HTTP request and downgrade the connection to steal session cookies on public WiFi.

How to fix: Add header: Strict-Transport-Security: max-age=31536000; includeSubDomains; preload — then submit to hstspreload.org.

Content-Security-Policy (CSP)Failed

Why it matters: CSP is a strong defense against XSS attacks. Without it, any injected script runs with full privileges. CSP blocks inline script injection.

How to 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.

DNSSECWarning

No DNSKEY records — zone is unsigned

Why it matters: Without DNSSEC, attackers controlling intermediate resolvers can forge responses for your domain — sending users to phishing sites with valid HTTPS that match your name. EU national CSIRTs (SK-CERT, NÚKIB) recommend DNSSEC for all in-scope entities.

How to 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.

CAA DNS RecordWarning

No CAA records — any CA can issue certificates for this domain

Why it matters: CAA records limit which Certificate Authorities can issue certificates for your domain. Without CAA, a compromised or rogue CA can issue valid certs that browsers will trust — a documented breach pattern (DigiNotar 2011, Symantec 2017).

How to 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.

HTTP → HTTPS RedirectWarning

Why it matters: Without a redirect, users can access the insecure HTTP version. Google also treats http and https as separate URLs, splitting your SEO signals.

How to fix: Configure a 301 redirect from http:// to https:// for all pages. In Apache: RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

Referrer-PolicyWarning

Why it matters: Without a referrer policy, browsers send the full URL to third parties. This can leak sensitive data like session tokens in URLs or internal page paths.

How to fix: Add header: Referrer-Policy: strict-origin-when-cross-origin — this is the best balance between functionality and privacy.

Permissions-PolicyWarning

Why it matters: Without Permissions-Policy, any third-party script (ads, analytics, chat widgets) can access camera, microphone, and geolocation without your knowledge.

How to fix: Add: Permissions-Policy: camera=(), microphone=(), geolocation=(), payment=() — disable APIs your site doesn't need.

Cookie Security FlagsWarning

3 cookie(s): 2 missing HttpOnly, 2 missing SameSite

Why it matters: Missing Secure flag = cookies sent over HTTP (stealable on WiFi). Missing HttpOnly = cookies readable by XSS. Missing SameSite = vulnerable to CSRF attacks.

How to fix: Set all cookies with: Secure (HTTPS only), HttpOnly (no JS access), SameSite=Lax or Strict (CSRF protection). Session cookies MUST have all three.

Subresource Integrity (SRI)Warning

Only 0/4 SRI-eligible third-party scripts have integrity hashes (2 auto-updating provider script(s) excluded — SRI not applicable)

Why it matters: Without SRI, if a version-pinned third-party CDN is compromised, attackers can inject malicious code into your site — the same vector as the British Airways Magecart breach.

How to 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.

CDN / WAF ProtectionWarning

Why it matters: Without a CDN/WAF, your origin server is directly exposed to DDoS attacks, bot traffic, and brute-force attempts.

How to fix: Add a CDN/WAF like Cloudflare (free tier), Sucuri, or Fastly. They provide DDoS protection, bot filtering, and SSL management.

Cookie Prefix SecurityInfo

1 session cookie(s) already have Secure + HttpOnly + SameSite; adding the __Host- prefix is a cosmetic hardening nicety

Why it matters: With Secure, HttpOnly and SameSite already set, the prefix adds only host-only enforcement — low marginal benefit.

How to fix: Optional: rename to __Host-session (Secure; Path=/; no Domain) for defence-in-depth against subdomain cookie injection.

Mobile

63/100

Weight: 10% · 6 OK · 10 warnings · 1 failures · 20 total

Link Text Quality (WCAG 2.4.4)Failed

25/347 links (7%) have vague text

Why it matters: An excessive share of vague links breaches WCAG 2.4.4 (accessibility) and SEO best practice (Google uses anchor text to understand the target page). An EAA 2026 compliance risk.

How to fix: A high share of links are generic ('click here', 'read more', 'here', 'more'). Every link must make sense out of context — 'Winter jacket product detail' rather than just 'Detail'.

Mobile Performance ScoreWarning

59/100 (target: 90+)

Why it matters: Most e-commerce traffic is mobile. Google ranks based on mobile performance, not desktop.

How to 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.

Desktop/Mobile Performance GapWarning

Desktop: 91 vs Mobile: 59 (32 point gap)

Why it matters: Google uses mobile-first indexing — your mobile score IS your SEO score. A big gap means your desktop optimizations aren't reaching mobile users, who are the majority of your traffic.

How to 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.

Touch Target SizeWarning

Some tappable targets are too small or too close together (Lighthouse tap-targets audit)

Why it matters: Small tap targets cause mis-taps on mobile. In e-commerce, a mis-tap on 'Remove from cart' instead of 'Checkout' directly loses revenue.

How to 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.

Font Size ReadabilityWarning

Some text renders below the 12px legibility threshold (Lighthouse font-size audit)

Why it matters: Text smaller than 16px forces mobile users to pinch-zoom. This breaks the responsive layout and creates a frustrating experience.

How to 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.

PWA FeaturesWarning

Why it matters: PWAs combine the best of web and native apps. For e-commerce, PWAs enable push notifications, offline browsing, and home screen access.

How to 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.

Theme ColorWarning

Why it matters: Theme-color creates a polished, branded mobile experience. It makes your site look native and professional.

How to 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.

Responsive Images (srcset)Warning

76 images without responsive sizing

Why it matters: Without srcset, mobile users download full-size desktop images, wasting bandwidth. Responsive images are the single biggest mobile performance win for image-heavy sites.

How to 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.

Mobile Sticky CTAWarning

Add-to-cart button found but no sticky/fixed positioning detected

Why it matters: Mobile users scroll extensively. A sticky add-to-cart bar keeps the primary action visible. Without it, users must scroll back up to purchase — many won't.

How to 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.

Print StylesheetWarning

Order/invoice page without print styles

Why it matters: Customers print order confirmations and invoices. Without print styles, they get navigation bars, cookie banners, and broken layouts. This is a common usability complaint for e-commerce.

How to 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.

Heading Hierarchy (WCAG 1.3.1)Warning

Skipped levels: h2→h4

Why it matters: Skipped heading levels (h1 straight to h3) break screen-reader navigation and signal poor document structure to Google. SEO suffers too.

How to 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.

Viewport ConfigurationPassed

Payment Methods DetectedInfo

No known payment gateway detected on the homepage

Why it matters: Visible payment icons (Apple Pay, Google Pay, Klarna, Tatra Pay) in the header or footer lift conversion. A trust signal before checkout.

How to fix: Payment gateway detection only scans the homepage. If payments live on /checkout or are loaded by JS after an interaction, we cannot see them. Consider adding payment icons to the footer.

Express Checkout (Apple Pay + Google Pay)Info

Apple Pay / Google Pay not detected on the homepage — express checkout usually appears only in the cart or checkout

Why it matters: Mobile conversion with express checkout beats manual card entry, and it is a growing trend in SK/CZ. (The scan only sees the homepage, so treat this as a hint rather than a verdict.)

How to fix: If you have no express checkout, add Apple Pay and Google Pay via Stripe, Adyen or Mollie. Biometric auth removes a click from checkout, which lifts conversion.

SK/CZ Local Payment MethodsInfo

No SK/CZ local payment method detected on the homepage — bank buttons and QR payment usually appear only in checkout

Why it matters: An SK/CZ shop without bank buttons and QR payment sees heavy cart abandonment; the average Slovak e-shop offers several payment methods. (The scan only sees the homepage — verify in your checkout.)

How to fix: If you do not offer SK/CZ local payments, integrate GoPay or ComGate — both cover Tatra Pay, VÚB Pay, ČSOB Pay, Raiffeisen and QR payment through one API. Barion is an alternative for the CZ market.

How to 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.

Structured Data FoundationWarning

Only 1 distinct schema type (BusinessEntity) — insufficient for AI visibility

Why it matters: Single-schema sites get minimal AI coverage. AI models need multiple data signals to confidently recommend your store.

How to fix: One schema type is not enough. Add at minimum: Organization (identity), Product (commerce), BreadcrumbList (navigation), WebSite+SearchAction (discoverability), FAQPage (Q&A answering).

Zero-results RecoveryWarning

A search with no matches appears to be a dead end

Why it matters: A shopper who searched has already decided to buy. A dead end sends them to a competitor who stocks the same product. Note: read from page HTML, so a search that renders results in JavaScript may be misread — verify before acting.

How to fix: On the no-results page show best-sellers or items from the nearest category, offer a spelling correction, and give a direct way to ask (chat, phone, form). Log the queries that return nothing — they are a free list of what customers want and you don't stock or don't name the way they do.

FAQ Schema (Direct AI Answers)Warning

Why it matters: ChatGPT, Perplexity, and Google AI Overviews pull FAQ answers verbatim. FAQ schema is one of the fastest ways to get your content cited by AI.

How to 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).

Breadcrumb SchemaWarning

Why it matters: 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'.

How to fix: Add BreadcrumbList schema reflecting your category hierarchy: Home → Category → Subcategory → Product. Each item needs name and URL.

Site Search Schema (SearchAction)Warning

Why it matters: SearchAction enables Google's sitelinks search box and allows AI shopping assistants to search your catalog directly. It's how AI agents find specific products in your store.

How to fix: Add WebSite schema with potentialAction: SearchAction. Define your search URL template so AI assistants and Google can search your store programmatically.

Answer-First Content FormatWarning

Content doesn't start with a strong summary paragraph

Why it matters: AI assistants extract content from the first 100 words to generate summaries. Most AI systems read top-down, so answer-first pages get cited more often.

How to 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.

Structured Content (Lists & Tables)Warning

33 lists found — consider adding comparison tables

Why it matters: AI models are biased toward extracting data from HTML lists and tables. Perplexity and ChatGPT pull bullet points and table data with higher accuracy than paragraph text.

How to 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.

Author Expertise Signals (E-E-A-T)Warning

Why it matters: AI models weight author expertise heavily. Pages from identified experts get cited more than anonymous content. This is especially important for product guides, reviews, and advice content.

How to 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.

Product Feed (AI Commerce)Warning

Why it matters: 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.

How to 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.

Heureka XML FeedWarning

Why it matters: Heureka.sk and Heureka.cz are the dominant price comparison engines on the SK/CZ market. Without an XML feed you're not visible on the main marketplace. No generic audit tool checks this.

How to 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).

Extractable Answer BlocksWarning

39 paragraphs, avg 19 words — too short for citation

Why it matters: AI extracts individual paragraphs as answer snippets — dense walls of text get skipped. Focused 40-80 word paragraphs are the most citable.

How to 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.

Statistics & Data PresenceWarning

No statistical data found in content

Why it matters: Content without data is harder to cite. Perplexity and ChatGPT specifically seek pages with quantified claims and verifiable statistics.

How to 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.

Section Length OptimizationWarning

Avg section: 188 words — only 31% in 80-200 word optimal range

Why it matters: For Google AI Overviews, 100-150 words per section is the sweet spot — long sections get skipped and very short ones lack substance.

How to 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.

Q&A Format HeadingsWarning

Why it matters: 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.

How to 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.

Canonical Tag for AI DeduplicationWarning

Canonical points to different URL: https://www.drevostav.sk/

Why it matters: 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.

How to 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.

Shipping Details SchemaWarning

Why it matters: Fulfillment speed factors into AI product recommendations. Complete shipping schema means AI can show 'Free shipping, delivers in 2-3 days' — a strong conversion driver.

How to fix: Add OfferShippingDetails schema with: shippingRate, shippingDestination, deliveryTime (handlingTime + transitTime). AI agents deprioritize products without shipping info.

Content Readability for AIWarning

Grade 20 — too complex for broad AI citation (technical threshold: 14)

Why it matters: Content above grade 12 readability is harder for AI to extract as clear, concise answers. Pages using clear headers and approachable language are cited more often.

How to 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.

Image Alt Text Quality for AIWarning

88% good, 3 poor, 1 missing

Why it matters: AI uses alt text to understand images for visual search (Google Lens, Bing Visual Search), product recommendations, and accessibility. Quality alt text opens more discovery channels.

How to fix: Improve alt text: use 3-15 descriptive words per image. Include product name, key feature, and context. Bad: 'image1' or 'photo'. Good: 'Red leather wallet with RFID protection — front view'.

Expert Quotations & CitationsWarning

Why it matters: Content without citations or expert quotes appears unverified to AI. AI assistants prefer content backed by named sources, data references, and expert opinions.

How to 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).

WebMCP Agentic ReadinessWarning

Why it matters: WebMCP is how AI agents will interact with your store (search products, add to cart, check availability). Google and Microsoft are co-developing this standard.

How to 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.

Trust WidgetWarning

No trust widget (Heureka / Trustpilot / AggregateRating) detected

Why it matters: SK/CZ buyers trust Heureka Ověřeno more than other trust signals. LLMs (ChatGPT, Perplexity) and Google SGE cite shops with AggregateRating schema first.

How to 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.

AI Bot Access PolicyPassed

No AI bot restrictions (allowed by default)

AI agent access (live)Passed

ChatGPT-User and PerplexityBot get the same page as a browser

Internal Link DensityPassed

45 contextual internal links per 1,000 words — strong knowledge graph signal

Return Policy SchemaPassed

MerchantReturnPolicy found — AI shopping agents can show return info

Knowledge Graph ReadinessPassed

3/4 entity signals — strong Knowledge Graph presence

Content-to-Boilerplate RatioPassed

69% of text in <main>/<article> — clean content signal

llms.txt (AI Site Descriptor)Info

Valid llms.txt with 4000 chars — proper format with H1, links, summary

Why it matters: No answer engine consumes llms.txt for AI-search citation today (2026) — adoption is ~8.7% and Google declined to support it. It's optional future-proofing, mainly read by coding/IDE agents. Prioritize AI-crawler access, server-rendered content, statistics and cited sources instead. See /ai-readiness-methodology.md.

llms-full.txt (Complete AI Content)Info

Not present — not required for AI visibility

Why it matters: 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.

Product Schema CompletenessInfo

No Product schema on this homepage — Product schema lives on product detail pages, which this single-URL scan didn't visit

Why it matters: 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.

How to fix: 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.

Search Typo Handling (measurement)Info

A correctly spelled query and the same query with a typo return similarly sized pages (198823 B vs 198823 B) — consistent with typo tolerance

Why it matters: This is a raw measurement, not a verdict, and it is never scored: page size is only a proxy for result count and themes differ. It is here so you can see what we saw.

How to fix: Verify by hand: search for a product, then search again with one letter transposed. If the second search finds nothing, a search engine with fuzzy matching and synonyms will recover those sales.

Reviews & Ratings SchemaInfo

No review schema on this homepage — review/rating schema typically lives on product pages

Why it matters: Review schema is product-page-specific, so its absence here is expected, not a defect.

How to fix: Scan a product URL to audit review schema. On product pages add AggregateRating (ratingValue, reviewCount, bestRating) and individual Review schemas.

AI Plugin ManifestInfo

Not present — not required (the ChatGPT-plugins manifest was retired in 2024)

Why it matters: 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.

GTIN/EAN CoverageInfo

No product feed was sampled — GTIN/EAN coverage could not be verified

Why it matters: GTIN is how an AI shopping agent matches your product to the same product in other shops. Without a feed we cannot measure it — this is not a finding against you.

How to fix: Publish a Google Merchant or Heureka product feed with GTIN/EAN populated, then re-scan to measure coverage.

Speakable Content (Voice AI)Info

Not present — optional; SpeakableSpecification has limited assistant adoption

ai.txt (AI Permissions)Info

Not present — optional; AI-bot permissions are enforced via robots.txt, not ai.txt

Why it matters: ai.txt is an emerging standard for fine-grained AI permissions beyond robots.txt. It gives you control over how AI uses your content.

Agent-Commerce ReadinessInfo

73/100 — partly ready (Access 100 · Understand 75 · Discover 50 · Transact 67)

Why it matters: Whether an autonomous shopping agent (a ChatGPT operator, Perplexity, the assistants coming next) can do four things on your shop: get in, read and understand the products, discover the whole catalogue, and act (cart, terms). Almost nobody measures this, and for SK/CZ shops nobody does.

Agent: Access — can an agent get inInfo

100/100 (2 signals)

Agent: Understand — can it read the productsInfo

75/100 (2 signals)

Agent: Discover — can it find the whole catalogueInfo

Agent: Transact — can it act (cart, terms)Info

67/100 (3 signals)

Legal & Compliance

86/100

Weight: 10% · 12 OK · 2 warnings · 1 failures · 17 total

Consumer Dispute Resolution LinksFailed

No EU ODR platform or supervisory-authority link found

Why it matters: EU Regulation 524/2013 makes the ODR link mandatory for every online trader; national law requires naming the supervisory authority. ŠOI/ČOI inspect for exactly this, and its absence is a common consumer-law breach.

How to 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.

Nariadenie (EÚ) 524/2013 (ODR) · Smernica 2013/11/EÚ (ADR) · SK zák. 391/2015 Z.z. · CZ zák. 634/1992 Sb. § 14

Cookie PolicyWarning

Why it matters: The ePrivacy Directive requires transparent cookie disclosure. Vague statements like 'we use cookies for functionality' don't meet the specificity requirement.

How to 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.

Right to Erasure (Data Deletion)Warning

Why it matters: GDPR Article 17 gives users the 'right to be forgotten.' EU regulators expect a clear, accessible process, and obstructing erasure requests is a documented enforcement finding.

How to 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.

Cookie Consent Banner (CMP)Passed

Online Withdrawal FunctionInfo

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.

Why it matters: Directive (EU) 2023/2673 (amending 2011/83/EU), transposed in SK as § 20a zák. 108/2024, requires online traders to provide an easy-to-use withdrawal function — a clearly labelled button, continuously available during the withdrawal period — effective 19 June 2026 for all distance contracts with a right of withdrawal. Orientation only — verify placement manually.

How to fix: Add a clearly labelled withdrawal function to your online interface (SK label: 'odstúpiť od zmluvy tu'), easy to find and continuously available during the 14-day withdrawal window — e.g. in the customer account / order detail plus a footer link. A logged-in customer must be able to submit a withdrawal declaration without re-identifying.

Legal guarantee noticeInfo

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.

Why it matters: Directive (EU) 2024/825 (amending 2011/83/EU) requires traders to remind consumers, in a harmonised notice prominently displayed on the website, that the legal guarantee of conformity exists and lasts at least 2 years. National rules apply from 27 September 2026.

How to fix: Show the EU harmonised notice on the legal guarantee of conformity as a general reminder on your website (e.g. in the footer or on every product page), using the official design and wording for your language from the Commission implementing act. A 'záruka 24 mesiacov' line on the product is not the same thing — the notice is about the statutory guarantee.

Vulnerability

57/100

Weight: 10% · 6 OK · 4 warnings · 5 failures · 15 total

Known Vulnerabilities (CVE)Failed

5 CVEs associated with 1 detected component version

Why it matters: Versions with published CVEs are a prime automated-scanner target — bots (Shodan, Greynoise, Mirai-family) probe for them within minutes. This finding is inferred from the detected version, so confirm the component is actually unpatched before treating it as exploitable.

How to 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

Admin Panel at Default URLFailed

Accessible at: /admin

Why it matters: Default admin URLs receive thousands of automated brute-force attempts daily. Botnets target /admin, /wp-admin, /administrator relentlessly. A renamed path blocks 99% of automated attacks.

How to 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).

jQuery VersionFailed

jQuery 1.11.3 — critically outdated!

Why it matters: jQuery 1.x is associated with 6+ known CVEs including XSS and prototype pollution. Automated scanners specifically target sites with jQuery <3.0.

How to 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.

DMARC Policy (Email Auth)Failed

Why it matters: Without DMARC, attackers can send perfectly spoofed emails as your brand. Since May 2025, Google, Yahoo, and Microsoft require DMARC for bulk senders. Missing DMARC = email deliverability problems.

How to fix: Add a DMARC TXT record at _dmarc.yourdomain.com: v=DMARC1; p=quarantine; rua=mailto:dmarc@yourdomain.com — start with quarantine, then move to reject.

Payment Page SecurityFailed

Payment page missing: No HSTS, No CSP

Why it matters: Payment pages without proper security headers violate PCI DSS and make card data theft significantly easier. Payment processors can impose monthly fines for non-compliance.

How to fix: CRITICAL: Your payment page is missing security headers: No HSTS, No CSP. PCI DSS Requirement 6.5 mandates protection against common vulnerabilities on pages handling card data.

Form CSRF ProtectionWarning

13/14 forms have CSRF tokens

Why it matters: Forms without CSRF tokens allow cross-site request forgery — an attacker's site can submit orders, change settings, or modify data on behalf of your logged-in users.

How to fix: Ensure ALL forms include a CSRF token. In PrestaShop, use {$csrf_token} in templates. In WordPress, use wp_nonce_field().

DKIM Signing (Email Auth)Warning

Why it matters: DKIM cryptographically signs outgoing email to prove it comes from your domain. Without DKIM, email providers downgrade trust score — transactional emails land in spam. Gmail and Yahoo require DKIM since 2024 for bulk senders.

How to fix: Configure DKIM signing through your email provider (Google Workspace, Microsoft 365, Mailchimp, SendGrid). Publish the DKIM public key as a TXT record at <selector>._domainkey.yourdomain.com.

Cross-Origin IsolationWarning

Why it matters: Without cross-origin isolation headers, your site is vulnerable to Spectre attacks that can leak sensitive data across browser tabs. These headers are required for SharedArrayBuffer and high-resolution timers.

How to fix: Add Cross-Origin-Opener-Policy: same-origin and Cross-Origin-Resource-Policy: same-origin headers. These protect against Spectre-type side-channel attacks.

Login Form SecurityWarning

Why it matters: NIST guidelines recommend allowing password autofill. Blocking it forces users to choose weak, memorable passwords — a leading cause of credential compromise.

How to fix: Remove autocomplete='off' from login forms. Password managers improve security by enabling unique, complex passwords per site.

CMS Version DisclosurePassed

Image Alt TextWarning

1 of 76 images missing alt text

Why it matters: Every image missing alt text is content a screen-reader user cannot access (WCAG 1.1.1 / EN 301 549 § 9.1.1.1).

How to fix: Add alt text to the remaining images (alt="" for decorative ones).

Heading StructureWarning

Heading outline issue (h1 count: 1h2→h4, h2→h4)

Why it matters: A clean heading hierarchy is the primary way assistive-tech users skim a page (WCAG 1.3.1 / 2.4.6).

How to fix: Use a single <h1> and don't jump heading levels (e.g. <h2> straight to <h4>).
