Greiner Bio-One
(https://gbo.com) 📸 Data Snapshot: May 30, 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 avoids trust theatre entirely; its review_count is 0, and it makes no attempt to use unverified customer testimonials. Instead, it relies on ‘hard’ proof paths, such as the ISO9001 certificate link which redirects to a third-party audit site (NQA). The proof_links_count of 2 per page reflects a deliberate strategy of linking to official regulatory and certification bodies rather than superficial social proof.
Proof density is exceptional for this industry. The ratio of verifiable evidence to assertions is high, with the site providing a searchable database of 402 technical documents. Specific proof points include the ISO 13485 MDSAP Certificate for the Kremsmünster facility and the mention of specific academic networking events at the University of Aberdeen and Oxford.
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.
