To an indie author, Goodreads isn't about selling your book; the primary goal is discoverability. In the best case scenario, your reader will give you a glowing review and a five star rating. Are they done? Nope! Bookshelves on Goodreads are what other sites consider tags, categories and/or genres. We like tags! We need tags! Why? Because they help bring new readers to our page. Ask you friends to shelve their books accordingly; it's an easy step and then; don't forget to say THANK YOU 😊
