Recently certified sites.

• Eligibility: your latest scan is Launch Ready — a score of 90 or more and zero blockers. Any open blocker caps the verdict, so there's no certifying around a broken link.
• Opt-in: you choose a display name and whether to appear on this page. Nothing is listed without you asking.
• The certificate page shows the score, verdict, date, Standard version and all 9 dimension bars, the breakdown behind the number, verifiable by anyone.
• The badge is a flat SVG you can embed; it links to the certificate. It's tied to that scan, so re-certify after changes to refresh it.

Only the site owner can certify a domain. The full rules are on the methodology page.
