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.

Industrial, Manufacturing & Engineering BS: Efficient Power Conversion Corporation (epc-co.com)

https://epc-co.com 📍 Industry: Industrial, Manufacturing & Engineering
5 BS / 100

EPC is a high-substance engineering site that prioritizes technical utility and documented proof over marketing theater. It successfully targets a professional engineering audience by providing tools and specifications rather than empty power words. The BS score is near zero due to the total alignment between manufacturer claims and functional evidence.

To achieve a near-zero score, EPC should integrate Person schema for its featured experts and blog authors to bridge the minor authority gap. Explicitly listing ISO certification numbers within the H2 hierarchy would provide immediate forensic proof of quality claims. Adding a dedicated ‘Quality & Reliability’ page with downloadable certification documents would satisfy the missing_elements of material traceability. Finally, ensuring the ‘Ask a GaN Expert’ call-to-action leads to verified professional profiles would eliminate the last traces of generic messaging.

The website perfectly aligns with the Industrial, Manufacturing, and Engineering sector, specifically focusing on semiconductor technology. The content confirms a highly specialized niche in Gallium Nitride (GaN) power devices, moving beyond general manufacturing into high-precision electronics.

“The score of 5 is driven primarily by the high specificity of information and the absence of semantic drift. Minor points were deducted only for the lack of individual expert footprints and the use of standard template markers for news and support. The site represents the gold standard for low-BS technical manufacturing communication.”
