Domain verification
Domain verification is a one-time DNS TXT challenge that proves you control the hostname before geodeck activates llms.txt, sitemap, feed, and visibility endpoints for your site. Since 2026 we resolve the token live over DNS-over-HTTPS, so propagation typically completes in 1 to 5 minutes on more than 95% of registrars. The token is unique per domain and only needs to resolve once. You can leave the record in place forever without any periodic re-checks.
How does domain verification work?
- Add a domain in the dashboard. We generate a unique token.
- Create a DNS TXT record at
_geodeck.<hostname>with the token as value. - Click Verify. We resolve the record over DNS-over-HTTPS.
What does an example DNS TXT record look like?
Type: TXT Name: _geodeck.example.com Value: gd_v1_abc123...
What if verification fails?
- Propagation: most registrars publish within 1–5 minutes; some take up to 30.
- Apex vs subdomain: the record name is the literal
_geodecklabel below your hostname – do not include the apex twice. - CNAME chains: the lookup follows DNS resolution; CNAME is fine.
- Already verified: you can leave the record in place – we do not periodically re-check.
