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.

Crypto, Blockchain & Web3 BS: OpenSea (opensea.io)

https://opensea.io 📍 Industry: Crypto, Blockchain & Web3
50 BS / 100

OpenSea is a utility-first platform that relies on its market position to bypass the need for substance, resulting in a Moderate BS score of 50. The site is technically honest about what it sells but uses unverified review counts and generic ‘best-in-class’ language to create a facade of authority. It effectively functions as a data dashboard that lacks the transparent proof and deep information density expected of a market leader.

Integrate external proof links for the review counts on all pages to transition from trust theatre to verified substance. Replace the generic ‘best place’ copy with specific monthly volume or user count metrics to increase information density. Implement Organization schema on the homepage with sameAs links to official corporate registries and executive profiles to close the authority gap. Add a technical ‘How it Works’ section that explains the curation or trending logic to substantiate performance claims.

The content perfectly matches the Crypto, Blockchain & Web3 industry classification, utilizing specific terminology such as onchain, NFT marketplace, ETH, and token trading. Structured data for NFT collections and tokens further confirms the business model as a decentralized asset exchange.

“The score is primarily driven by the Trust and Proof pillar (16/20), where the discrepancy between review counts and zero proof links created a high penalty. Information Density (15/30) also contributed significantly due to the near-total lack of descriptive or qualifying text. The site performed best in Semantic Coherence (3/20), as its functional headers and metadata are logically aligned with the actual services provided.”
