For custom domains whose usage is to serve a hosted, the custom domain will be used to load a webpage (e.g. preference center). Some characteristics of the serve a hosted page usage designation is:

* Can only be linked to one widget
* Custom domain must be detached from its widget before it can be deleted
* Can only be used by one widget at a time
* The custom domain's URL is used by the end-user to access the widget
  {% endtab %}

{% tab title="Serve the Didomi SDK" %}
For custom domains whose usage is to serve the Didomi SDK, the custom domain will be used to load the Didomi SDK. Some characteristics of the serve Didomi SDK usage designation is:

* Can be used for consent notices, preferences widgets, and privacy request widgets
* A custom domain can load several products at once
* Custom domain is included in the implementation snippet used to load and display the widget/notice
