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.

Medical Devices, Pharma & Biotech BS: Pfizer Inc. (PREVNAR 20®) (prevnar.com)
This site is a benchmark for low-BS clinical communication, prioritizing regulatory precision over marketing hyperbole. It operates with transparency by providing direct access to FDA-compliant labeling and specific strain-count data. The minimal score is derived solely from the use of standard pharma templates and repetitive clinical phrasing.
To achieve a near-zero score, explicitly list the FDA approval date and Biologics License Application (BLA) number within the footer for immediate regulatory validation. Replace the generic heading For Adults with more granular clinical trial population descriptors, such as Adults 18 Years of Age and Older. Include a direct link to the ClinicalTrials.gov registration numbers for the pivotal studies mentioned in the prescribing information. Finally, add a section for pharmacovigilance that explicitly states the mechanism for reporting adverse events beyond the hidden schema data.
The site perfectly matches the Medical Devices, Pharma & Biotech category. The content is explicitly clinical, focusing on therapeutic areas such as immunology and infectious disease, while utilizing specific regulatory-compliant language regarding vaccine valency.
“The score of 4 is driven primarily by the Commodity Fingerprint (2 points) and minor Information Density repetition (1 point). The site avoided all penalties for trust theatre, semantic drift, and authority gaps. It is a highly substantive pharmaceutical property that uses technical specificity to validate its primary health claims.”
