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.
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.
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.
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.
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.
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.
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.

Home Services (Plumbing, Roofing, HVAC, Electrical) BS: Vaillant (vaillant.com)
Vaillant is a rare case of a high-substance manufacturer wrapping itself in high-BS corporate packaging. While the product data is technically sound, the digital presentation suffers from massive trust theatre and a lack of structured authority signals. It effectively proves it builds good hardware but fails to prove its market leadership claims through external verification.
Implement comprehensive Organization and Product schema to bridge the technical authority gap and support the technology leader claim. Replace unverified claims like most silent in the market with links to independent acoustic test results or certifications. Consolidate the 150 years of history messaging to a single page and use that space on other pages for live service network metrics or real-time CO2 savings data. Add external proof paths by linking to verified third-party review platforms or industry award bodies.
The website perfectly aligns with the Home Services category, specifically focusing on renewable heating and HVAC technology. The content confirms the brand’s position as a global manufacturer of heat pumps, boilers, and smart home climate controls.
“The score of 44 is primarily driven by Trust and Proof gaps (13 points) and Identity and Authority failures (11 points). The total absence of schema and the presence of unverified market leadership claims are the heaviest contributors. The site's Information Density (13 points) is penalized for heavy power-word usage in headings despite having technical data in the body text.”
