A literary genre is a category of literary composition. Genres may be determined by literary technique, tone, content, or even (as in the case of fiction) length. The distinctions between genres and categories are flexible and loosely defined, often with subgroups.
Remember, the more you include the more interest your audience will have in checking out your tour appearance. And it will be more fun than sitting at a table waiting and hoping for someone to stop by and purchase your book. (One of the drawbacks of traditional book tours is you may sit for hours and none or few people stop by. It can be a real downer. But a virtual tour is not that way.)
Make use of reviewers. Who are they, especially those with a positive view.
