Now, you can use this to showcase your landing page and your product. For example, your website is then you can add to the Root URL. So when users go on URL they will see your webpage instead of the Outgrow website.

Similarly for error URL, if you have a page set up on your website for 404 error, you can add it while setting up Custom Domain. So when a calculator or quiz is not found on a given URL then your error page shows up instead of the default Outgrow error page.

Important Note

Two key things for having the CNAME as the address of your main website are:

1. Host / Subdomain is WWW for CNAME.
2. When adding in outgrow include www. in the URL.
