Science on Cleaning and Detergents (Masaru Oya)
(https://detergent.jp) 📸 Data Snapshot: May 26, 2026Count 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.
The site contains zero trust theatre elements; there are no review_count or proof_links_count scores because the site does not rely on third-party testimonials to validate its claims. The authority is derived directly from the listed academic credentials of Professor Masaru Oya, including his status at Yokohama National University and the Open University of Japan. No bold, unsubstantiated performance claims (e.g., ‘we are the best in the world’) are present.
The proof density is high, supported by the specific mentions of academic papers, TV appearances, and lectures. The ratio of verifiable technical topics to vague assertions is heavily weighted toward verifiable information. Even the sub-page for English learning provides a specific, numbered list of 50 songs, maintaining a consistent pattern of high information density even in non-scientific content.
Trust & Proof is read by weighing trust language against real verification. Below is the page-by-page tally of review mentions and external proof links, then the schema markup that may (or may not) declare verifiable ratings and identity proof.
