Your Diagnosis

Before revealing the machine’s verdict, predict the BS score for each signal. Higher = more BS (more fluff, less verifiable substance). Drag each slider, then submit to compare your judgment against the engine.

Information Density 0 / 30
Read the Narrative & headings: do hard facts (prices, dates, numbers) outweigh fluff power-words?
Semantic Coherence 0 / 20
Compare the homepage promise against the sub-page reality. Do they hold the same line?
Trust & Proof 0 / 20
Weigh review mentions against actual external proof links. Claims without verification = theatre.
Commodity Fingerprint 0 / 15
Check headings & narrative against the industry clichés in the setup above.
Identity & Authority 0 / 15
Inspect the schema: is there real Organization/Person identity with sameAs links, or gaps?
Your predicted BS score 0 / 100
💡 Stuck? Reveal the heuristic lens — how the deterministic page-auditor reads each signal (no AI, pure pattern rules)

These are the structural rules a local, deterministic auditor applies — the same lens you can use to judge each signal. They describe what to look for, not this company’s result.

Information Density

Classify each sentence as substantive or hollow. Grounding markers — numbers, currencies, dates, technical units, named entities — outweigh marketing adjectives. When fluff sits right next to hard evidence, the fluff is forgiven.

Semantic Alignment

Pull the main entities out of the H1, then check whether they actually recur through the body. A page that announces one thing and then talks about another drifts. Headings with no real sentences underneath read as pseudo-substance.

Trust & Proof

Count trust words (review, testimonial, rating, verified) against real outbound proof links (Google, Trustpilot, Clutch, G2, Yelp). Lots of trust language with zero verification links is trust theatre. Unlinked logo galleries count against it.

Commodity Fingerprint

Look at how much sentence length varies. Natural writing varies its rhythm; templated or mass-produced copy is statistically uniform. Very low variation reads as commodity content — unless unique named entities break the pattern.

Identity & Authority

Inspect the JSON-LD. Is there an Organization or Person schema, and does it carry sameAs links to real external profiles (LinkedIn, socials)? Missing schema or no identity declaration signals an anonymous entity.

Want to apply this lens yourself? The free BS Indicator Chrome extension runs these heuristic checks live on any page. Bear in mind it is a single-page, deterministic tool — it relies only on pattern rules for the page in front of it and does not perform the cross-page semantic correlation this audit uses, so its readout is a starting lens, not the full verdict.

30 BS / 100

This is a low-BS, service-first website that prioritizes utility over marketing theatre. While it lacks the professional technical polish of a modern enterprise (evidenced by the Yahoo email and aging schema), it provides honest, specific information about its capabilities and service area.

Migrate from thedoubleglazingdoctor@yahoo.com to a domain-based professional email address to close the authority gap. Include specific FENSA, Certass, or Checkatrade registration numbers in the footer and structured data to provide regulatory proof. Replace generic ‘highly praised reviews’ text with 2-3 named client testimonials linked to specific projects. Add Person schema to the ‘family-run business’ claim, naming the principal owners to enhance human authority.

The site aligns perfectly with the home improvement and repair sub-sector, specifically focusing on glazing and fenestration. While the industry pattern dictionary focuses on high-end architecture, this business operates as a functional trade service, matching the practical expectations of its category.

“The score of 30 is driven by Identity and Authority gaps (Yahoo email, missing professional body registrations) and a high Commodity Fingerprint (copy-pasteable value prop). Semantic Coherence was 0, meaning the site is exceptionally honest about what it does, preventing a higher BS score.”
