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: London Plumbers (www.central-london-plumbers.co.uk)
This site is a ‘Ghost Template’ designed for SEO keyword harvesting rather than genuine service provision. It fails the most basic transparency requirements for the plumbing industry by omitting Gas Safe registration numbers and using unverified review counts. It is a high-BS lead-capture skin with zero substantive business evidence.
Immediately add the official Gas Safe Register ID number to the header and footer. Replace the identical ‘Few reasons to choose us’ heading blocks on service pages with unique, technical descriptions of the work performed (e.g., specific boiler brands serviced). Link the review count to a verifiable third-party profile like Checkatrade or Google Business to move from trust theatre to actual proof. Implement LocalBusiness schema with the ‘founder’ or ‘knowsAbout’ properties to establish technical authority.
The site strongly aligns with the Home Services (Plumbing) category. The content focus is entirely on domestic and commercial plumbing, boiler services, and drainage solutions in the London area.
“The score of 85 is driven primarily by Information Density (lack of specific nouns/numbers) and Commodity Fingerprint (use of generic templates). The Trust and Proof pillar also contributed significantly due to the display of review counts without verification links and the mention of Gas Safe status without a registration number. Semantic Coherence was slightly higher only because the site doesn't contradict its basic industry (plumbing), even if the content is repetitive.”
