Although giving a book for "free" may seem somewhat uneconomical, book giveaways help us deliver our book to readers effectively. We can acquire more reviews and gather potential fans for our work.
What you should keep in mind are "what to offer," "how much to give away," and "where to start the giveaway." We can provide free copies of our work to readers on social media platforms or Goodreads, as well as on Bookbub.
Alternatively, you can print out, for example, the first chapter of your book and distribute it offline. Train stations may be the perfect place for offline giveaways, as your book can provide people with a chance to pass the time during boring moments. Some authors insert their "samples" in best-sellers so that many people can come across them.
