How do you do an online book tour?

Hi Everyone - My new children's story, with the working title, Orion and the 3 Little Gnomes, will be released this May.  I am a relatively new author.  Could someone please explain how an author does an on-line book tour?

Thank you so much for your help.

Sincerely,

Rhonda Paglia, author
