Beta reading is done when a writer wants to get a feeling for how the story will be received. Does the story flow well? Are the characters fully developed? Do any parts of the story lag? I will also suggest any improvements that might be made with proofreading and copyediting. .
Proofreading is the last step in the wrting process. This is usually done after your book has gone through preliminary rounds of editing. It includes checking for errors in grammar, spelling, and punctuation. It is the last step before your novel is published.
Copyediting combines proofreading with additional services such as making the style consistent, flagging content inconsistency from chapter to chapter, flagging plot holes, and more.
