Hashtags are typically one word, and are used to describe the book. They can include the genre or categories that the book falls into, such as #fantasy or #horror, or they can include the type of book, such as #hardcover or #paperback.
We recommend adding as many hashtags as applicable, so that more people can see your book! PangoBooks has a limit of 10 hashtags per listing, and also suggests several applicable hashtags when you first list the book.
Some hashtags show up under Popular Searches in the "Shop" page, and many of our users check the tags daily for new listings! Adding tags is a great way to help your book find a new home.
