The diagnosis
A company with serious references — Strukton, the municipality of Schiedam — and a website that worked and brought in clients. But to Google, the business behind it barely existed: no structured business data (Identity 35/100), no security headers (Security 60/100), and partner logos a screen reader couldn't name. The Wosify inspection brought it all to light — and the initial measurement, 81 'Needs attention', was archived as a PDF before anything was touched.
Interventions made
- Structured business data (JSON-LD): real name, address, phone and opening hours, confirmed by the owner — Identity 35 → 100
- Four security headers served and verified twice (nosniff, anti-framing, Referrer-Policy, CSP) — Security 60 → 100
- Alt text in Dutch for partner logos — applied by the Wosify Connector with a prior backup and byte-exact rollback
- Static asset caching fixed: from 11 days to 1 year for CSS, JS and images
- Broken sitemap (404) caught in the re-scan and fixed the same day
- 803 site URLs checked: 0 real broken links
- The first automatic verification didn't sign off — the system stopped itself and nothing was closed until it passed human review

Website Health: from 81 to 96.
All data is real: both figures come from official Full Inspections by the same engine, both at 100% confidence and archived as PDFs. Of the 8 factors, seven improved or held steady; the Mobile factor moved from 88 to 84 due to Lighthouse variance between runs — we report it anyway.
