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.

Education, Schools & Universities BS: Zearn (zearn.org)

https://zearn.org 📍 Industry: Education, Schools & Universities
75 BS / 100

Zearn operates as a ‘ghost platform’ that hides behind a login wall, offering zero public-facing proof for its ‘top-rated’ claims. While its structured data is technically competent, the visible website is a textbook example of Trust Theatre—claiming authority without providing the evidence to back it up.

Create a public-facing homepage that replaces the login wall with an H1 stating specific student outcome metrics. Add a ‘Research and Efficacy’ section that provides external links to the third-party ratings mentioned in the meta description. Implement a clear heading hierarchy (H1-H3) that details the specific ‘visual models’ and ‘pedagogical frameworks’ used. Link the review count to a verifiable third-party review aggregator.

The entity identifies as an EducationalOrganization and nonprofit developing a K-8 math platform. This aligns perfectly with the Education category, specifically within digital learning and curriculum development.

“The score is primarily driven by the Information Density pillar (30/30) due to the 0 char_count and the Trust and Proof pillar (18/20) due to the presence of unverified claims and a trust theatre flag. The only factor preventing a higher score is the comprehensive and accurate JSON-LD schema.”
