Copy editors catch spelling mistakes, errors in grammar, and inconsistencies in your text. They know when compound words are hyphenated (or not), whether the book is ‘laying’ or ‘lying’ on the table, and whether eagles have ‘talons’ or ‘claws.’ They’ll go through your manuscript line by line for accuracy and consistency of style. A good copy editor will make sure that your voice remains intact while restructuring sentences, and substituting weak word choices for stronger ones.
An edit requires a substantial investment, many times greater than the cost of a book. Editors who spent years as assistants, learning the craft of editing and acquiring the knowledge of how to guide authors, are a safer choice. Their track record speaks for itself; editors at this level have bestsellers and award winners in both the traditional and the self-publishing space.
Ebook Launch helped make my first self-publishing project a success. They responded promptly when I had questions prior to hiring them for a custom ebook cover and .mobi and .doc formatting. Their price was about half what was quoted by format and book cover freelancers, so I was pleased that I got my money's worth. They sent two book cover variations and we worked through suggestions to improve on one. My book cover design turned out great. I look forward to working with them again in the future.
If you’re a first-time author and have never hired an editor before, I would not recommend hiring an editor without first getting a sample edit. An editor can have a great resume and speak eloquently on the phone, but the real test of their skills is how they edit your book, and the sample edit is a quick, free way to find out. It’s standard for a freelance editor to offer a free sample edit unless they are exceptionally well-known.
Even if you wrote the book in your free time, this is my day job. The per-project cost many new authors would consider “manageable” would, if broken into an hourly rate, end up paying editors less than minimum wage. They don’t intend to pay what someone could earn making french fries; they just greatly underestimate how much time must be invested in editing.

The single most decisive factor should be the quality of the edit itself: Will this editor help improve your book? In order to assess this, nothing beats a sample edit (even if you have to pay for it). Testimonials and credentials (such as experience at a major NY publisher) can help you narrow your list, but you should submit the same sample to a variety of editors and compare their work side by side. Some editors will push too hard, and some won’t push hard enough; some will simply “get” your writing, while others will seem to speak another language entirely. In my experience, the editor’s résumé is far less revealing than the quality of the sample edit. In fact, the higher an editor’s pedigree, the more reluctant the editor might be to provide a sample edit. Don’t be afraid to insist: no one should expect you to invest in a car without a test drive!
An extensive critique of my first novel led to major changes in the format. I was very fortunate to have an experienced novel writer to give a detailed analysis, with corrections. I did not fully appreciate, at the time how valuable this process was, but do now. You need to acknowledge that there are likely to be inconsistencies leading up to the final manuscript and be prepared to make drastic changes. An editor is attuned to picking up on these, where you have accepted the script , even after numerous re-writes!
2. Copyeditors aren’t the last line of defense when it comes to a book’s mistakes. Formatting, which is done after an editor has done their job, can lead to unintended errors being introduced into the text. That’s why it’s important to hire proofreaders to comb through edited text *after* the book has been formatted for print or digital. Proofreaders are your last line of defense—but they’re human too.
