Publish note internet

Hi, I'm thinking about Joblin Cloud. I would be very interested in the Publish note internet service.
But I have a few questions:

  1. What the published page looks like (can I ask for a link to the preview).
  2. It is also possible to publish under folders, that I choose the folder that I will publish and all the .md files and folders in it are published.
  3. Is such a page indexed by Google.
    Thank you very much for the answers.
