What are genres, categories, and subcategories? Why are they important?

The terms genre and category are often used interchangeably. If we’re being precise, genre designates a broad category like fiction or nonfiction while categories are more specific like  romance, horror, business, or memoir. To make things even more complicated, there are many subcategories under many categories. These genres, categories, and subcategories come in strings (see examples below).

Think of genres, categories, and subcategories like virtual shelves that help organize books. Though you don’t get to label these shelves, you do have an opportunity to choose the best shelves for your book—and the more specific your choice, the better the chance your book will stand out. It’s part of the secret sauce we use at Bublish to propel unknown authors’ books to #1, which unlocks organic exposure and enhances discoverability by the right readers.

To show you what this looks like, here are some fiction and nonfiction category strings. On a retailer like Amazon, three category strings typically appear on a book’s product page. Note how specific the last subcategory is in each string.
