Serokell
(https://serokell.io) 📸 Data Snapshot: May 24, 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.
Trust points are slightly reduced due to the AggregateRating schema claiming a 5.0 rating across 9-13 reviews without providing direct verification links to a third-party platform like Clutch or G2 on the analyzed pages. However, the ‘proof_links_count’ on the contacts and projects pages, combined with the presence of named, high-profile clients like the Tezos Foundation, provides significant verified substance.
The ratio of evidence to fluff is exceptional. The site lists over 20 detailed case studies with named entities and technical deliverables. The blog content is not marketing-led but consists of original research and technical tutorials, which serves as proof of capability rather than just a claim of it.
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.
