FinalFix Guide

Add a Custom Domain to Your Landing Page

A custom domain is your own address, such as example.com or www.example.com. It replaces the temporary preview URL visitors see during setup.

Quick summary

Decide whether to use root, www or both, add the domain to your Pages project, follow DNS prompts and allow time for propagation and certificate activation.

Root domain, www and subdomains

The root domain is example.com. A subdomain is something before it, such as www.example.com or landing.example.com. Many landing pages connect both root and www so visitors can type either version.

1.Choose the primary version you will share.
2.Add both root and www if you want both to work.
3.Redirect one version to the other later if needed.

Tip: Consistency matters for analytics, SEO and sharing.

DNS in plain language

DNS is the internet’s address book. It tells browsers which service should answer when someone types your domain. Cloudflare will tell you which records to create or confirm.

1.Open the Pages project.
2.Go to Custom domains.
3.Enter your domain.
4.Follow Cloudflare’s DNS instructions.

Tip: A CNAME commonly points a subdomain such as www to the hosting target.

Propagation and checking

DNS propagation is the delay while changes become visible across networks. It may be quick, but waiting is normal. SSL certificate activation can also take time.

1.Keep the pages.dev preview URL available.
2.Check root and www versions.
3.Try mobile data and Wi-Fi if one network caches old DNS.
4.Update your FinalFix canonical URL before clean export.

Tip: Do not keep changing records repeatedly while propagation is in progress.

Common mistakes

Only connecting www when you plan to share the root domain.
Deleting DNS records without understanding what they do.
Assuming DNS failed after only a few minutes.
Forgetting to update canonical metadata to the final domain.

FAQ

What is a CNAME?

A CNAME is a DNS record that points a subdomain to another hostname, such as a Cloudflare Pages target.

Do I need both www and the root domain?

Not always, but connecting both prevents confusion and lets visitors use either address.

Why does my domain work for me but not someone else?

DNS caches can update at different times. Give propagation more time and verify the records are correct.
