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.
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.
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.
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.
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.
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.
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.
Based on 1453 businesses audited.
Kérastase has 0.4 points less BS than the average for Beauty, Cosmetics & Personal Care.
Beauty, Cosmetics & Personal Care BS: Kérastase (kerastase.com)
Kérastase successfully leverages its salon-heritage brand equity to mask a fairly standard commodity e-commerce structure. The BS score is moderate, driven by the gap between ‘professional diagnosis’ and a simple web quiz, as well as the usual beauty-industry reliance on small-sample consumer perception tests. It is a polished marketing machine where technical substance is relegated to footnotes.
Add deep-link citations to full clinical trial methodologies rather than just asterisked footnotes on the homepage. Implement Person schema for lead stylists or formulators to bridge the expert authority gap. Replace generic power words in H1 and H2 tags with specific technical outcomes, such as pH-balance levels or specific breakage reduction percentages. Provide a full INCI ingredient transparency page that explains the science behind the ‘hyaluronic infusion’ claims.
The site content perfectly aligns with the Beauty and Hair Care category, specifically targeting the high-end professional salon niche. All product references (shampoos, masques, oils) and service offerings (Fusio-Dose) are consistent with industry standards.
“The score of 45 reflects Moderate BS, primarily driven by Information Density (repetitive product categories) and Trust Theatre (reviews without verification links). The site scores well on Semantic Coherence because it delivers the salon-search and product-discovery functions it promises. However, the lack of named experts in the structured data and the high use of industry clichés prevent a lower BS score.”
