Trust & Proof: Genentech / Evrysdi – Signal Evidence & AI Readability

Genentech / Evrysdi

Trust & Proof — The Lens

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.

Trust & Proof Verifiable evidence vs. Trust Theatre.

The site avoids trust theatre entirely; its review_count is 0, which is appropriate for a regulated prescription medication where consumer reviews are often restricted. Instead of unverified testimonials, the site utilizes ‘Important Safety Information’ blocks and links to ‘Full Prescribing Information,’ providing a high level of verified regulatory proof rather than theatrical social proof.

The proof density is high, with a proof_links_count of 2 per page specifically pointing to technical prescribing documents. Specific clinical trial metrics (2 years of maintained results across SMA types) outnumber vague assertions, creating a site that is functionally a digital label and patient support portal rather than a sales pitch.

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.
