How do I change my default domain for creating links?

When shortening links, you can choose which domain you would like your links to be automatically shortened with. By default, the bit.ly domain will be selected. If you have a custom domain configured to your Bitly account, you set this as the default domain for new links.

1. Log in to your Bitly account.
2. Click Settings in the left sidebar.
   
3. Under Account settings, select Groups.
   
4. Select the group you would like to change the default domain for.
   
5. If you have enabled your custom domain for the group you have selected, you will see the option to toggle between the bit.ly domain or your custom domain. Once updated, click Update Default Domain.
   
   If your custom domain isn't listed, select Add Custom Domain, choose your custom domain, and click Save Domains. You can then set it as your default domain.

And there you go! The newly selected domain will be used automatically when shortening links.
