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: Mastervolt (mastervolt.com)

https://mastervolt.com 📍 Industry: Industrial, Manufacturing & Engineering
49 BS / 100

Mastervolt is a legitimate industrial entity suffering from a stale digital presence that prioritizes corporate platitudes over technical proof. The score is held in the moderate range by the presence of real product categories and global office locations, but is weighed down by a complete lack of modern trust verification and missing technical SEO foundations.

Immediately update the vision statement to reflect goals beyond 2022 to remove stale content penalties. Publish the ISO 9001 certificate number and link to the official accreditation document. Implement Organization and Product schema to provide a verifiable digital identity. Replace generic philosophy pillars with specific case studies detailing how the 300W-40kW systems performed in demanding offshore environments.

The site strongly aligns with the Industrial, Manufacturing & Engineering category, specifically focusing on autonomous power solutions and electrical components. The content consistently references power ranges, electrical categories like inverters and chargers, and specific industrial niches such as marine and offshore.

“The score of 49 is driven primarily by high Trust and Proof gaps and technical Identity failures. While the company provides more substance than a typical marketing shell, the combination of a null schema, missing H1 on the homepage, and unverified reviews creates a significant distance between its claim of being a technical leader and its digital reality.”
