Beta readers are individuals who read a manuscript before it is published to provide feedback to the author. They help identify issues such as plot holes, character development, and pacing, offering insights from a reader's perspective. This feedback is valuable for authors to refine their work and enhance its appeal. Typically, beta readers are part of the target audience for the book, which allows them to provide relevant opinions. They may be friends, family, or members of writing groups. Their role is crucial in the writing process, as they help ensure the final product resonates with readers.
