Mostly human-written
72% confidence
The score is a fingerprint of automation, not a quality judgment. A high score means the page reads as machine-generated. It doesn't mean the page is bad.
This is a technical product specifications page written in engineering register—specific load values (100 N, 1,500 RPM, 0.5 mm lead), named internal data ("internal preliminary Ca 0.8 kN"), and caveats ("Treat the result as an RFQ triage screen, not a guaranteed catalog rating") are hallmarks of human technical authorship. The structure is custom (calculator + report, not templated), and the tone is consistent but sparse (no personality, no jokes, but also no generic "leverage" phrasing). Word count of 1,950 is substantial enough to signal. The page reads like an OEM datasheet, not an AI-generated marketing site. The combination of specificity, internal references, and engineering-grade caution strongly indicates human technical writing.

- Worth notingContent
Conservative screening language avoids guarantees, protecting against liability but risking customer confusion.

FAQ and risk-control sections appear late in the page flow; front-load common hesitations to reduce scroll friction.

Signals of human authorship the page is doing well.
- Content
Named internal engineering data (Ca 0.8 kN, duty-cycle boundaries) and specific caveats demonstrate genuine technical knowledge, not template filling.
- Tone
Consistent first-person engineering voice ('we support', 'our data') with no marketing rhetoric; reads as authentic OEM documentation.
- Content25
Technical product specs, named load ratings, and engineering caveats dominate; no listicle phrasing or AI marketing templates detected.
- Structure35
Clear section-by-section layout with subsections, but lacks boilerplate hero/features/testimonials flow; custom calculator integration is atypical of AI builders.
- Imagery30
Only 3 images present, all properly alt-tagged; no stock-photo grid or uniform overlays; imagery minimal relative to text depth.
- Tone20
Consistent engineering-first voice with caveats ("treat the result as an RFQ triage screen, not a guaranteed catalog rating") and zero marketing flourish.

Each bar is one sentence of the page, in reading order — taller means longer. Human prose tends to look jagged, mixing short punches with long explanations. Machine drafts tend to flatten into even bars.
Computed from the body text we crawled, split on punctuation and filtered to prose-length sentences. Rhythm is a heuristic, not a verdict — some human writers are metronomically even, and a good editor smooths a machine draft.
No common LLM-marker phrases found — none of the stock AI vocabulary we scan for appears in the body text even once.
- Meta tagsAll presentWhy this matters
Why it matters. Title and description are the two strings Google shows in search results. They decide whether anyone clicks. A canonical tag tells Google which URL is the source of truth when the same content lives at multiple paths.
Passing looks like. A non-empty title under 60 characters, a meta description under 160, and a self-referencing canonical link.
Fix. Add the missing tags inside the page head. Treat the title as a headline you'd want to read in a SERP, not a brand slogan.
- Heading structure1 H1, 12 H2Why this matters
Why it matters. Headings are how crawlers and assistive tech understand a page's outline. One H1 names the page. H2s break it into sections. Skipped levels and missing H1s confuse both.
Passing looks like. Exactly one H1, at least one H2, and no skipped levels (no H1 to H3 jumps).
Fix. Replace the missing or duplicate H1 with a single, descriptive heading. Promote section titles to H2. Demote sub-points to H3.
- Mobile readinessResponsiveWhy this matters
Why it matters. Google indexes mobile-first. A page without a responsive viewport renders zoomed-out on phones, fails Core Web Vitals on touch, and loses its mobile ranking.
Passing looks like. A meta viewport tag with width=device-width and a layout that reflows under 600px.
Fix. Add a viewport meta tag set to width=device-width and initial-scale=1, then audit your largest blocks at mobile widths.
- Page speed signals0.5s · 216 KBWhy this matters
Why it matters. Page weight and response time directly feed Core Web Vitals. Slow LCP and oversized HTML hurt rankings more than people expect.
Passing looks like. First-byte under 1.5s, HTML payload under 500 KB, fewer than 30 images on the initial render.
Fix. Trim render-blocking scripts, defer non-critical CSS, and serve compressed images sized to the viewport. Move heavy components below the fold.
- Schema markup5 schema blocksWhy this matters
Why it matters. JSON-LD structured data is how you earn rich results: review stars, FAQ accordions, breadcrumbs, article cards. Skip it and Google has nothing structured to pull from when it builds your SERP card.
Passing looks like. At least one valid JSON-LD block matching schema.org types relevant to the page (Article, Product, FAQPage, Organization).
Fix. Add an application/ld+json script block describing the page. Validate with Google's Rich Results Test before deploying.
- Broken links0/5 broken in sampleWhy this matters
Why it matters. Broken internal links waste crawl budget, degrade UX, and signal to Google that the site isn't well-maintained. They also cap how deep crawlers reach.
Passing looks like. Every internal link in the sample returns 2xx or 3xx. No dead anchors, no stale paths.
Fix. Use the link list above to spot the broken paths. Either restore the missing pages or update the links to point at live URLs.
- Image alt textAll have altWhy this matters
Why it matters. Alt text is what screen readers read aloud, and what Google reads instead of pixels. Skip it and you lose on both fronts.
Passing looks like. Every meaningful image has a descriptive alt attribute. Decorative images can use alt="" to be skipped intentionally.
Fix. Audit images in /assets and CMS uploads. Write alts that describe what's in the image, not what it links to.
