About

SiteAge.org

SiteAge.org is a website age certification platform. We trace the origins of websites using multiple archival and registry sources and generate verifiable age badges.

How It Works

  1. 1 Enter a domain name to look up
  2. 2 We query the Wayback Machine, certificate transparency logs, domain registries, and Common Crawl for the earliest evidence
  3. 3 The earliest date found across all sources becomes the "birth date"
  4. 4 You receive a certificate page and an embeddable SVG badge

Verification

Website owners can claim their domain through DNS TXT record or meta tag verification. Verified domains receive a gold "Established" badge and can submit evidence for an earlier birth date if our automated sources didn't capture the earliest version.
