Changing Subdomain to a Custom Domain
Kajabi ensures that your site can be accessed through your Kajabi Subdomain and your connected Custom Domain!
Connecting a custom Domain to your Kajabi site (even after your site has been live for some time) will allow your visitors to access your site with both your original Kajabi Subdomain and your connected Custom Domain.
You launch your site with the Kajabi subdomain, myawesomesite.mykajabi.com, then decide to connect your custom domain to Kajabi (i.e., myawesomesite.com).
Your site visitors can access your site with both the Kajabi subdomain, myawesomesite.mykajabi.com and your connected custom domain, myawesomesite.com!
Change your Kajabi Subdomain to a different Kajabi Subdomain
Unfortunately, it isn't possible to natively set up a 301 redirect to the new subdomain.
If you start with a Kajabi subdomain (e.g., helpcenter.mykajabi.com), gain traffic, and then change it at a later date (e.g., articles.mykajabi.com) the old subdomain will show up as a non-existing page.
