Share by Folder - new Google Sites
Publish a site to your G Suite domain only but share further via Google Drive
Share externally via Google Drive
- Publish your Google Site to your G Suite domain only
- Create a Google Drive folder and share with your external viewers to the folder (either directly by email address or a group).
- Find your site in Drive (either navigate or search for type:site)
- Move the site into the shared Drive folder
The site will automatically inherit the view permission added to the Google Drive folder so those users who can view the folder will be able to view the site at the published URL.
