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.

Ecommerce & Online Retail BS: Costco Wholesale (www.costco.com)

https://www.costco.com 📍 Industry: Ecommerce & Online Retail
31 BS / 100

Costco is refreshingly low on linguistic bullshit, opting for a cold, utilitarian presentation of facts and prices. However, the ‘substance’ of the site is crippled by technical infrastructure failures that render large portions of its value proposition inaccessible. It is a site that tells the truth in its copy but fails to deliver the content in its code.

Fix the server-side Access Denied errors on the Grocery and Optical sub-pages to restore substance to your categorical claims. Remove review counters and trust signals from system error pages like the Page Not Found view to eliminate trust theatre flags. Implement Organization and LocalBusiness JSON-LD schema on the homepage to provide technical authority and link to verifiable entities. Consolidate the redundant H2 footer headings to improve the heading hierarchy coherence score.

The content strongly confirms the Ecommerce & Online Retail classification through warehouse-specific terminology and membership-based value propositions. The presence of transactional elements like tiered appliance discounts and warehouse location finders aligns with a high-volume retail model.

“The score of 31 is driven primarily by technical failures and trust theatre flags on non-content pages. The site scores very low (meaning high substance) in Information Density and Commodity Fingerprint due to its focus on hard numbers and unique business model. The Identity and Authority pillar is the highest penalized due to the lack of structured data and high page error rate.”
