Custom tracking domain with Cloudflare DNS

Use Jelto's managed tracking domain with Cloudflare DNS. You need permission to edit your domain's DNS records.

Set up the record

  1. In Jelto, open Settings → Installation → Custom tracking domain, save an unused hostname such as analytics.example.com, and copy its CNAME target.
  2. Open the domain in Cloudflare, go to its DNS records and add a CNAME. Set the name to your chosen subdomain, for example analytics, and the target to the value displayed by Jelto. Choose DNS only for this tracking record.
  3. Wait for the change to be visible, then run the DNS/TLS check in Jelto.
  4. Copy the updated installation tag, publish it on your website and verify traffic.

Keep the boundaries clear

The DNS-only choice applies to this dedicated tracking subdomain. You do not need to change the proxy status of your main website.

If your website uses a content security policy, add the new tracking origin to script-src and connect-src, as shown in Endpoints and content security policy. Update optional helper URLs to use the same host.

Verify

Check DNS/TLS status and then an actual new pageview. A DNS success alone does not prove the script was published; a saved hostname alone proves neither DNS nor TLS.

For common failure states, use Custom tracking domain.
