You’ve written your novel. You’ve revised, edited, and polished until your characters shine and your plot sings. Now you’re faced with one final challenge before you can publish: writing a book blurb. It’s short, it seems simple—but it might be one of the hardest parts of marketing your book.
Why? Because your blurb isn’t just a summary. It’s a sales pitch. A good blurb doesn’t just explain what your book is about—it makes readers want to read it. Here’s how to write a book blurb that sells.
Know the Purpose of a Blurb
A blurb is not a synopsis. It’s not a summary of every character arc or subplot. Instead, it’s a teaser, a hook, and a promise.
Think of your blurb as a movie trailer in text form. It should:
- Spark curiosity.
- Set tone and genre expectations.
- Introduce a compelling conflict.
- Leave the reader needing to know what happens next.
Start with a Hook
The first sentence should grab the reader’s attention. This could be:
- A bold statement: “Death was only the beginning of her problems.”
- A provocative question: “What if your soulmate was the person you were sent to kill?”
- A high-stakes premise: “In a world where memories are currency, hers have just been stolen.”
Whatever you choose, it should be specific, emotional, and intriguing
Introduce the Main Character(s)
Readers want someone to root for. Introduce your protagonist with a hint of voice and urgency. Mention:
- Who they are.
- What they want.
- What’s standing in their way.
Kara Vance is a disgraced journalist chasing one last story to save her career. But when the story turns into a conspiracy that could collapse the government, Kara must choose between the truth and her own survival.
Notice how this gives just enough detail to create investment, without overwhelming the reader.
Set Up the Conflict
Once the reader is hooked, layer in the stakes. What danger, challenge, or emotional journey does your protagonist face?
Be clear, but don’t give away too much. Focus on:
- The external conflict (e.g., war, murder investigation, alien invasion).
- The internal conflict (e.g., fear, grief, betrayal).
As Kara dives deeper, secrets come to light—secrets someone is willing to kill to keep buried.
End with a Cliffhanger or Question
Your final line should leave the reader hungry. Don’t resolve the tension—ramp it up.
Examples:
- “Can she uncover the truth before she’s silenced forever?”
- “But the more she uncovers, the more she wonders if the truth was ever hers to find.”
- “What she learns could save the world . . . or doom it.”
Tailor for Your Genre
Blurbs are not one-size-fits-all. A romance blurb should promise emotional tension and payoff. A thriller should emphasize urgency and danger. A fantasy blurb should evoke wonder and stakes.
Study top-selling books in your genre. Pay attention to:
- Structure
- Tone
- Vocabulary
- Common tropes
Then model yours accordingly.
Use Clear, Compelling Language
This is not the place for passive voice or overly complex sentences. Use:
- Active verbs.
- Short paragraphs.
- Emotionally charged words.
Read it aloud. Does it flow? Does it spark curiosity? If not, trim and tighten.
Avoid Common Pitfalls
Here are some mistakes to avoid:
- Too many names. Stick to one or two key characters.
- Vague stakes. “She must face her fears” is weak. “She must outwit the assassin who knows her every move” is better.
- Genre confusion. A cozy mystery shouldn’t sound like a gritty noir.
- Spoilers. Tease the story, don’t tell it.
Test It Out
Before you hit “publish,” test your blurb:
- Share it with critique partners or readers.
- A/B test two versions in ads or on social media.
- Ask: Would you buy this book based on this blurb?
Revise as Needed
Even after publication, you can tweak your blurb. Especially if you’re self-publishing, don’t be afraid to adjust the wording, swap sentences, or rewrite entirely based on feedback and sales data.
