How to Write Back Cover Copy That Sells Your Book
Give Your Book a Pitch Readers Can’t Resist
A reader picks up your book, glances at the cover, and flips it over. Or they click your Amazon listing and scroll to the description. In the next few seconds, a short block of text decides whether they buy, borrow, or move on.
That text is your back cover copy, and it’s one of the most important pieces of writing you’ll ever do for your book. It’s also one of the hardest. After spending months or years on a full manuscript, condensing it into 150 compelling words can feel impossible.
This guide explains what back cover copy is, why it matters, a simple formula for fiction and nonfiction, how to adapt it for Amazon, mistakes to avoid, and an example to learn from.
What is back cover copy?
Back cover copy is the short, persuasive description of your book that appears on the back cover (or inside the jacket flaps of a hardcover) and on retailer pages like Amazon. It goes by several names:
➜ Back cover copy or back-of-book copy
➜ Book description, the term used by Amazon and most retailers
➜ Jacket copy, for hardcovers with dust jackets
➜ Blurb, a common informal term, though in publishing “blurb” often means an endorsement quote from another author
Whatever you call it, its job is the same: make the right reader want to read your book.
Back cover copy vs. synopsis vs. endorsements
| Back cover copy | Synopsis | Endorsements (“blurbs”) | |
|---|---|---|---|
| Audience | Readers | Agents and publishers | Readers |
| Purpose | Sell the book | Show the full story and structure | Lend credibility |
| Length | ~150–250 words | 1–2 pages | One or two sentences each |
| Reveals the ending? | Never | Yes | No |
| Written by | Author or publisher | Author | Other authors, critics, experts |
Why back cover copy matters
It’s your sales pitch. After the cover and title, the description is the main thing readers use to decide.
It sets expectations. Good copy signals genre, tone, and audience, so the right readers buy and the wrong ones don’t end up disappointed.
It works everywhere. The same core copy appears on your back cover, Amazon and retailer pages, your website, press kits, catalogs, and pitches to bookstores and libraries.
It affects reviews. When copy accurately sets expectations, reviews tend to be better, because readers get the book they were promised.
The back cover copy formula
For fiction
The hook: an opening line that grabs attention with a striking situation, question, or voice.
The character and setup: who your protagonist is and what their world looks like when the story begins.
The conflict: what disrupts that world, the problem they can’t ignore.
The stakes: what they stand to lose, and why it matters.
The tease: a closing line that raises a question or creates tension without answering it.
For nonfiction
The hook: name the reader’s problem, question, or desire.
The promise: what the book will help them understand, do, or change.
The proof or approach: what makes this book different, and why the author is the right guide.
The benefits: what readers will gain, often as a short bulleted list online.
The call to action: an invitation to start reading.
For memoir
Memoir blends both approaches. Introduce the author’s central experience and conflict like a story, then hint at the larger meaning or lesson readers will take away.
Length and format
Print back cover: about 150–200 words, with 250 as a ceiling. Leave room for endorsements, an author photo or bio, and the barcode.
Amazon and retailer descriptions: Amazon KDP allows up to 4,000 characters. You can use the same core copy, or expand slightly with a bulleted list (for nonfiction) or a short line about the series or author.
Formatting online: KDP supports basic HTML formatting such as bold, italics, headings, and bulleted lists. A bold first line and short paragraphs make descriptions much easier to scan.
What not to include on Amazon: KDP doesn’t allow reviews, quotes, or testimonials in the description itself, along with contact information, website links, time-sensitive details, or spoilers. (KDP description guidelines) Add editorial reviews through Amazon Author Central instead.
Tips for writing compelling back cover copy
➜ Study your genre. Read the descriptions of 5–10 recent bestsellers in your category. Notice their tone, length, and structure.
➜ Lead with your strongest line. Many readers never get past the first sentence.
➜ Focus on one main character and one central conflict. Subplots can wait.
➜ Write in present tense and third person (for fiction). It’s the convention, and it creates immediacy.
➜ Match the tone of the book. A cozy mystery should sound charming. A thriller should feel urgent. A memoir should feel intimate.
➜ Use specific details, not generic phrases. “A disgraced pastry chef” is more intriguing than “a woman with a troubled past.”
➜ Cut ruthlessly. Every word should earn its place.
➜ Read it out loud. If it doesn’t flow, revise.
➜ Test it. Share it with readers in your genre and ask, “Would you buy this?”
Common mistakes to avoid
✘ Summarizing the whole plot. Back cover copy is a teaser, not a synopsis.
✘ Giving away the ending or major twists.
✘ Introducing too many characters, names, or places.
✘ Relying on clichés like “a journey of self-discovery,” “nothing will ever be the same,” or “a story you’ll never forget.”
✘ Being vague about the actual conflict.
✘ Writing about the author instead of the book. The bio belongs elsewhere.
✘ Mismatching the genre, for example making a quiet literary novel sound like a thriller.
✘ Making it too long for the back cover.
Example: before and after
(A fictional example.)
Before
The Lighthouse Keeper’s Daughter is a story about family, secrets, and finding yourself. Maggie has always lived in her small coastal town, but when her father dies, everything changes. She learns many things about her family and her past, and goes on a journey that will change her life forever. Along the way she meets new people, faces challenges, and discovers what really matters. This heartwarming novel will make you laugh and cry.
After
For thirty years, Maggie Doyle’s father kept the light burning on Gull Point, and kept his silence about the night her mother disappeared.
Now he’s gone, the lighthouse is being sold, and Maggie has one month to clear out a lifetime of his belongings. But hidden beneath the floorboards of the keeper’s cottage is a stack of unsent letters, each addressed to a woman Maggie has never heard of.
As a winter storm cuts the island off from the mainland, Maggie must decide how much of the truth she’s willing to uncover, and whether some lights are meant to stay dark.
What changed:
➜ A specific, intriguing hook replaced generic phrasing.
➜ Concrete details (the lighthouse, the letters, the storm) replaced vague summary.
➜ A clear conflict and deadline create urgency.
➜ The ending is left open, with a question that makes readers want to know more.
➜ The clichés are gone.
Why professional help with back cover copy pays off
Many authors find their book description harder to write than the book itself. They’re too close to the story to see what an outsider needs to hear. An experienced editor or marketing professional can help you:
➜ identify your book’s strongest selling points and hook
➜ match the copy to your genre’s expectations
➜ save hours of frustrating rewrites
➜ produce copy that works across your back cover, Amazon page, website, and press materials
Because this short piece of writing influences nearly every sale, it’s one of the most valuable places to invest a little expert help.
How to Write Back Cover Copy: FAQ
How long should back cover copy be?
About 150–200 words for a print back cover, with 250 as a maximum. Online descriptions can run a little longer. Amazon allows up to 4,000 characters.
Is back cover copy the same as a synopsis?
No. A synopsis summarizes the full story, including the ending, for agents and publishers. Back cover copy is a teaser for readers and never reveals the ending.
Is a “blurb” the same as back cover copy?
The terms are often used interchangeably, but in publishing “blurb” usually means a short endorsement from another author or expert. Back cover copy is the description of the book itself.
Should back cover copy be written in first or third person?
For fiction, third person and present tense are the standard, even for first-person novels. For memoir, either can work, but third person is more common on covers.
Can I use the same description on Amazon as on my back cover?
Yes, and many authors do. Online, you can add formatting like a bold opening line or bullet points, but don’t include reviews, quotes, or links in an Amazon description.
When should I write my back cover copy?
Start drafting once your manuscript is finished, and finalize it before your cover design is complete, since the back cover layout depends on its length.
