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.

To achieve a near-zero BS score, the site should include direct, clickable outbound links to published clinical trial data on PubMed or ClinicalTrials.gov. Adding a ‘Last Updated’ timestamp to each specific disease page would improve transparency for the 2026 temporal context. Specifically, the homepage H1 could be replaced with a more technical, product-focused headline to match the substance of the sub-pages. Finally, adding Person schema for the Chief Medical Officer or lead researchers would close the institutional authority gap.
The content perfectly matches the Pharmaceutical and Biotech industry profile. It focuses entirely on a specific therapeutic antibody (rituximab), its mechanism of action on CD20-positive B-cells, and the regulatory indications for serious conditions like NHL and CLL.
“The score of 13 is one of the lowest possible for a commercial site, driven by high Information Density and zero Semantic Coherence issues. The remaining points are derived from the lack of direct outbound evidence links and the minor presence of generic corporate phrasing in the hero sections.”
