AI verdict

Your store runs well overall, but you have security gaps. Urgently add HSTS encryption protection to your website. Your SEO and accessibility are excellent.

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)

Performance

Weight: 25% · 8 passed · 6 warnings · 4 failed · 2 SPA (verify manually)

What we found: 6.3 MB, 140 requests — too heavy!

Why it matters: Pages over 3 MB take 12+ seconds on 3G. The average e-commerce page is around 2 MB — you're well above that. Even small latency increases measurably reduce sales.

How to 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· Confidence: high

What we found: 2066 KB — more than double the 600 KB budget

Why it matters: Above 1 200 KB the parse and execute cost alone stalls mid-range phones for seconds before anything is interactive. For reference, the best shop in our benchmark ships 410 KB and won its award on mobile experience.

How to 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-lab2066 KB JavaScript· Confidence: high

What we found: 829 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 829 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: Only 33% of 12 scripts optimized — most are render-blocking

Why it matters: 8 render-blocking scripts can add 1-3 seconds to page load. Each synchronous script creates a sequential download-parse-execute chain.

How to 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· Confidence: high

What we found: 386ms (good: <200ms)

Why it matters: TBT measures how long the main thread is blocked. During this time, clicks and taps don't respond — your store feels frozen. This directly impacts perceived quality.

How to fix: Reduce JavaScript execution: defer non-critical scripts, code-split large bundles, remove unused plugins. Third-party scripts (analytics, chat, ads) are often the biggest offenders.
Evidence:PSI-lab· Confidence: high

What we found: 140 requests — over the budget of 80, but at or below the median of the award-winning shops we benchmarked (140)

Why it matters: The 80-request bar is best practice; the benchmarked cohort median is 140 and the best shop manages 37. Being under the median is not the same as being fast.

How to fix: Bundle CSS/JS that always loads together, serve icons as a sprite or font rather than individual files, and lazy-load below-fold images so they aren't requested on load.
Evidence:PSI-lab140 requests· Confidence: high

What we found: 79 images without lazy loading

Why it matters: Without lazy loading, ALL images download on page load — even those never scrolled to. On a product page with 20 images, lazy loading can save most of the initial download.

How to 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· Confidence: high

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

What we found: 11 CSS files loaded

Why it matters: Each render-blocking CSS file adds network latency. Consolidating CSS from 8 to 2 files can save 200-400ms on first load.

How to fix: Consolidate CSS files by bundling them into 1-3 files. Each CSS file is a separate HTTP request that blocks rendering until downloaded.
Evidence:HTML-heuristic· Confidence: high

What we found: 11 CSS files without critical CSS extraction

Why it matters: Render-blocking CSS delays first paint. Inlining critical CSS eliminates the render-blocking round trip — the biggest FCP improvement for CSS-heavy sites.

How to fix: Extract critical above-the-fold CSS and inline it in <head>. Load remaining CSS asynchronously: <link rel='preload' href='styles.css' as='style' onload='this.rel="stylesheet"'>.
