Before you start
- A paid plan. Custom domains are available on Pro and Premium.
- A domain you own, and access to its DNS settings at the company you bought it from.
- A website that is ready to publish.
Connecting takes three DNS records, verified in order. The dashboard shows the exact host and value for your domain beside each step. Use those, not values copied from anywhere else.
Decide between the root and www
yourbusiness.comis the root;www.yourbusiness.comis a subdomain. Some DNS providers cannot put a CNAME on the root and offer an ALIAS or ANAME instead. If yours offers neither, connect the www subdomain and redirect the root to it.Add the domain in your dashboard
Open Domains, choose to connect a domain you already own, and enter it. The three setup steps appear with the records for your domain.
Step one: prove the domain is yours
Add the verification
CNAMEexactly as shown, then press Verify.- Many DNS providers append your domain to the host automatically. Entering the full name then produces a doubled host that never verifies.
- If it does not pass immediately, wait (DNS changes take time to spread) and verify again.
Step two: let us issue an HTTPS certificate
Add the
CNAMErecord shown for the certificate step and verify it. This is what lets the certificate authority confirm you control the domain. You do not buy, install or renew anything.Step three: send traffic to us
Add the routing record and verify it. On a subdomain that is a
CNAME; on the root it is anALIASorANAME, or aCNAMEif your provider supports one at the root.- Remove any older record of the same type on the same host first; a conflict keeps the check failing.
Assign the domain to a website and publish
A verified domain serves nothing until it is attached to a website and that website is published. Attach it on the Domains screen, then publish.
Check it, then set your renewal preference
Open the domain in a private window. If the browser warns about the connection, the certificate is still being issued; the dashboard step shows where it is.
- For a domain bought through Instantsite, check the auto-renew setting. An expired domain stops resolving whatever else is configured.
Final checklist
- All three setup steps show as done in the dashboard.
- The domain is assigned to a website, and that website is published.
- The address loads over HTTPS in a private browsing window.
- Your Instantsite address still works as a fallback.
