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
IdentityStructured business data (JSON-LD): real name, address, phone and opening hours, confirmed by the owner — Identity 35 → 100
SecurityFour security headers served and verified twice (nosniff, anti-framing, Referrer-Policy, CSP) — Security 60 → 100
AccessibilityAlt text in Dutch for partner logos — applied by the Wosify Connector with a prior backup and byte-exact rollback
SpeedStatic asset caching fixed: from 11 days to 1 year for CSS, JS and images
GoogleBroken sitemap (404) caught in the re-scan and fixed the same day
Content803 site URLs checked: 0 real broken links
ProcessThe first automatic verification didn't sign off — the system stopped itself and nothing was closed until it passed human review
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.

// HOW THE WORK WAS DONE

Approved, backed up,verified and reversible.

A good result is worth nothing if you can't prove it. Every step of this case was recorded in an append-only audit trail: nothing gets deleted, nothing gets rewritten.

Approval before touching anything

The plan was approved in writing ("akkoord akkoord") and the quote was recorded immutably in the case file.

Verified backup

Backup checked before the first change (ref. WBAK-2026-D02BAC41E012). Every change is reversible.

Verified on the live site

Every change was checked against the real HTML visitors see, not the WordPress dashboard.

72 hours of observation

After the work, the site was watched for 72 hours without incidents before closing the case. Access was revoked at the end.
