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.
Based on 222 businesses audited.
Home Services (Plumbing, Roofing, HVAC, Electrical) BS: 東埼住設株式会社 (Tousai Jusetu Co., Ltd.) (tousai.com)
A stale ‘Digital Business Card’ that qualifies as a Ghost Site. While it lacks the aggressive buzzwords of a corporate scam, its total failure to provide forensic proof of competence or licensing in a regulated industry makes it a high-risk entity for a consumer.
Immediate inclusion of national license numbers for electrical and gas work is required to bridge the authority gap. Replace generic stock-style image references with a gallery of dated, named projects in Misato City. Implement a clear ‘Pricing and Process’ section to move from commodity claims to substance-based signaling. Link the internal review counter to a verifiable third-party platform.
The site perfectly aligns with the Home Services category, specifically targeting plumbing, electrical, and gas installation in Misato City. The service categorization is standard for a Japanese ‘jusetsu’ (housing equipment) firm.
“The score of 62 is driven primarily by the Trust and Proof pillar and the Information Density pillar. The site avoids the 'innovative synergy' type of BS but falls deep into the 'unsubstantiated commodity' trap, where the lack of proof is as damaging as the presence of fluff. The data is also stale, with the last modification occurring in 2021, nearly 5 years prior to the current system date.”
