The job of a book description
A reader on Amazon spends about 7 seconds deciding whether to keep reading your description or scroll on. They aren't looking for plot. They're looking for an answer to one question: is this the kind of book I love?
Your description has three jobs, in order:
- Hook: stop the scroll in the first two lines.
- Promise: show the experience this book delivers.
- Push: make the click feel obvious.
The structure (fiction)
- Tagline (1 line): the emotional hook in tweet form. Bold this in the formatted description.
- Setup (2–3 short paragraphs): protagonist, world, inciting incident. Stop before the spoilers. Build mood, not synopsis.
- Stakes (1 line): what happens if the protagonist fails. The "if she doesn't…" sentence.
- Tropes & comps (3–5 bullet points): "Perfect for fans of X. Includes: enemies-to-lovers, slow burn, small town setting, found family." This is what readers scan for.
- CTA (1 line): "One-click and start reading tonight." Or "Scroll up and grab your copy." Yes, really.
The structure (non-fiction)
- Pain hook (1–2 lines): name the problem the reader already feels.
- Promise (1 paragraph): the specific outcome this book delivers, with a number or timeframe if possible.
- What you'll learn (5–8 bullet points): concrete takeaways, not chapter titles. "How to…" beats "An exploration of…"
- Credibility (1–2 lines): why you, why now.
- CTA (1 line): "Scroll up and start reading today."

Before / after: non-fiction

After:
You don't need another to-do app. You need to stop ending every week feeling behind.

Format the description for Amazon
Use the basic HTML Amazon allows: <b> for the tagline, <i> sparingly for emphasis, and<br> for line breaks. Bullet lists scan better than paragraphs. Aim for 200–400 words total — long enough to sell, short enough to read.
Common mistakes
- Starting with the protagonist's age and job. Cut it.
- Using the description to summarise the plot. That's the back cover.
- Listing every character. Pick one.
- No call to action. Tell readers what to do next.
- A single grey wall of text. Format it.
