go.example.com is usually the simplest choice because it can be dedicated to Biqli without changing your main website. A root domain such as example.com can also be used when your DNS provider supports the record Biqli requests.
Choose a hostname that visitors will recognize and that is not already serving another application. The exact DNS record depends on the hostname, so always copy the name and value shown by Biqli instead of guessing them.
You must control the domain’s DNS and it must be available inside Biqli.
Root domain or subdomain
Use a subdomain when
example.com already hosts your company website, store, or
email-related web service. Choose a short word that clearly belongs to your
brand, such as go, link, or visit.
