The Indie Author's Launch Playbook

Everything below is how I read the research, not gospel. Amazon changes its rules often, so treat this as a map and check the exact wording in your live KDP dashboard before you act. Current as of July 2026. If you find that Amazon has changed something, please let me know and I will update this document.

Most launch advice online is written for one kind of book, usually romance or thriller, and then handed to everybody. So a picture-book author follows a romance playbook and wonders why none of it fits. This one runs the other way. There's a spine that's true for every book on Amazon, and then there are the places where genre changes the move. I'll give you the spine, and I'll flag the genre forks as we hit them.

I'm not a professional marketer. I'm a writer who dug through what actually moves a book on Amazon right now, turned it into something you can act on, and cited my sources at the bottom so you can pull the thread yourself.

How Amazon actually decides what to show

Amazon doesn't reward you for cramming keywords onto your page. It rewards three things working together: the right book put in front of the right shopper, that shopper actually buying it, and a few early reviews confirming it was worth the money. Speed sits on top of all of it. A cluster of sales in a few days is the signal that tells Amazon to start showing your book around on its own.

Hold onto that, because almost every choice below is really about one of those three levers: getting in front of the right person (categories, keywords, comps), converting them once you're there (cover, description, price), or proving it was worth it fast (reviews and launch velocity).

---

First, know your book's shape

Before the mechanics, get honest about what kind of book you've written, because a few things bend hard by genre. You'll see these come up again and again.

Who actually buys it. For most adult fiction, the reader and the buyer are the same person, so you write your page to the reader. For children's books, middle grade, and a lot of gift nonfiction, the reader is one person and the buyer is another (a parent, a teacher, a librarian, a spouse shopping for a gift). When they differ, every word on your page has to match how the buyer searches, not how the reader talks.

Print or digital. Romance, thriller, and science fiction and fantasy live mostly on Kindle. Children's books, middle grade, illustrated nonfiction, and a lot of literary fiction lean on print, because those buyers want a physical book and libraries and schools buy paperback and hardback. Put your effort where your format actually sells.

How fast your readers read. This one decides your whole Kindle Unlimited call, so I've given it its own section below. The short version: romance, thriller, and SFF readers devour books, so page reads pay. Literary, middle grade, and picture-book readers don't consume that way, so page reads don't add up to much.

Keep those three in your head. They're the difference between advice that fits and advice that just sounds official.

The pre-launch sequence

Whatever your genre, this is the order I'd run it in. Do the research first, because it feeds everything downstream.

As early as you can:

• Do the category, keyword, and comp research below. It shapes your description and your metadata, so it comes first.
• Start building a launch team (see the reviews section). This is the piece most first-timers leave too late.
• Make your two genre calls: Kindle Unlimited yes or no, and which formats you're running.

A week or two out:

• Lock the cover, description, categories, keywords, and metadata.
• Open a pre-order if you're publishing an ebook. I lean yes, reasons below.
• Line up your early reviewers and hand out your ARCs. An ARC is just an advance reader copy, a free early version you give reviewers before launch day so their reviews are ready to post the moment the book goes live.

Launch week:

• Bunch your reviews and your sales into a tight window. Velocity is the thing Amazon reads.

1. Categories: three per format, and the rule just changed

You pick up to three categories for each format, and the ebook, paperback, and hardback each get their own three. Choose the most specific categories that genuinely fit. A narrow, precise category is far easier to rank number one in, and that orange Best Seller badge is what turns a browser into a buyer. Amazon still lists you upward into the broader parent categories anyway, so you lose nothing by going specific.

Here's the part that trips up anyone reading older guides. There used to be a trick where you'd email KDP support and ask to be added to seven or ten categories beyond your three. That's gone. The three-per-format limit is firm now, set right in the dashboard. The way you reach extra browse categories today is through your keywords. Certain keyword phrases are tied to specific browse categories, so the right keywords quietly place you in categories your three slots didn't cover (Kindlepreneur maps a lot of these). So keywords aren't just search, they're your back door to more shelf space.

A genre-neutral way to pick your three:

• Slot one: your best-fit narrow niche. The most specific category that truly describes the book. "Medical Thrillers," not "Thrillers." This is where you can actually hit number one.
• Slot two: a different angle. Audience, theme, or setting rather than genre. It catches a shopper who'd never find you under slot one.
• Slot three: the broader home category, so you're present where the browsing happens.

Confirm the exact category names in the picker when you're in there, because Amazon renames and reshuffles them constantly.

---

2. Keywords: seven slots, about 50 characters each

A few rules that matter. Don't repeat words already in your title or subtitle, because Amazon indexes those automatically and you'd waste a slot. Use whole phrases a buyer would actually type, not single words. Remember who's typing (for kids' books, that's the adult). And since keywords take a day or two to index, change only one or two at a time so you can tell what's working.

The best research tool is free and sitting right there. Start typing seed phrases into the Amazon search bar and watch the auto-suggestions drop down. Those are real searches real people run. Type the start of a phrase for your genre and see what Amazon fills in.

Seed phrases by genre, to get you started (then let auto-suggest tell you the real ones):

• Romance: "enemies to lovers small town," "grumpy sunshine romance," "second chance billionaire."
• Thriller / mystery: "psychological thriller twist ending," "domestic suspense unreliable narrator," "small town detective series."
• SFF: "epic fantasy dragons series," "litrpg progression fantasy," "space opera first contact."
• Literary / upmarket: "book club fiction family secrets," "literary novel dual timeline."
• Middle grade / kids: "middle grade animal adventure," "chapter book age 8 9 10," "read aloud classroom."
• Nonfiction: lead with the outcome the reader wants ("how to sleep train toddler," "beginner sourdough guide"), because nonfiction buyers search the problem, not the topic.

Remember the keyword-to-category trick from the last section. A couple of your seven slots should be chosen partly to reach browse categories your three didn't grab.

---

3. The quiet metadata that still moves you

• Reading age (kids' and middle grade). Set it honestly, say ages 8 to 12. It feeds the filters parents and librarians shop with, and it's the number that travels. There's a US grade field too. Fill it in for the US store; don't sweat it if your country's year levels don't map cleanly.
• Series. If this is book one of anything, set up the series field from the start. A clean series page makes every future book easier to find, and read-through (a reader finishing one and buying the next) is where series authors actually make their money. Stitching a series together after the fact is a headache, so do it now. This matters most in romance, SFF, and thriller, where readers binge a series; it matters least for standalone literary fiction.
• Subtitle. A quiet subtitle can do keyword and promise work for the shopper scanning past. "A Small-Town Enemies-to-Lovers Romance" tells a romance reader everything in six words. Genres vary on how heavily they lean on this (romance and nonfiction lean hard, literary and MG keep it light), so test it against the bestsellers in your category.

4. The description: write it for whoever clicks Buy

Your description is the single biggest thing that turns a click into a sale. The exact shape shifts by genre, but the bones hold:

1. A hook line that makes the premise impossible to scroll past.
2. Two or three short paragraphs on the stakes and the promise, naming the exact feeling the buyer is shopping for.
3. A "for readers who love..." line with a couple of comp titles, so a buyer recognizes themselves.
4. A closing beat that reassures them it delivers (age-right for kids, the tropes present for romance, the payoff earned for thriller).

Where genre bends it:

• Romance buyers want the tropes named out loud. Enemies to lovers, forced proximity, grumpy-sunshine, guaranteed happy ending. Say them. That's not spoiler, that's the promise they're paying for.
• Thriller and mystery sell on tension and a hint of the twist, never the answer. Short, punchy, a question the reader needs resolved.
• SFF has to establish the world fast and signal the scope, then get to the character we'll follow.
• Literary and upmarket lean on voice and theme, and often borrow a line of praise up top.
• Children's and MG get written for the grown-up doing the buying: name the courage, the loyalty, the found-family stuff a parent wants to hand their kid, and reassure them it's age-right and worth the money.

Write it in your own voice, then read it cold and ask the only question that matters: would this make a stranger click Buy?

5. Comp titles do four jobs at once

Comps aren't just for the description. They tell you which categories and keywords to chase, they shape who Amazon parks you next to in the "customers also bought" strip, and they show you which covers are winning in your corner of the shelf.

Find yours the direct way. Search your genre and subgenre on Amazon, pull up the five or six books that are clearly selling and clearly close to yours, and study each one: what categories does it sit in, what does its cover do at thumbnail size, how is its description built, and who shows up in its "also bought" row. You're not copying. You're learning the visual and structural language your reader already expects, so you can meet it and then stand out inside it.

Pick comps that are genuinely close and genuinely selling. A comp that's too big ("the next Hunger Games") reads as a red flag, and a comp nobody bought tells you nothing.

---

6. The cover

If you've already had a cover made, hold it against this checklist rather than redoing anything. A cover has two jobs: stop the right reader, and reassure them it's a professional, finished book.

The one rule that beats all the others is legibility at thumbnail size. Most shoppers first meet your cover about the size of a postage stamp in a search result. If your title and your central image read at that size, you're in good shape. If they turn to mud, nothing else about the cover matters.

Beyond that, covers are a genre language, and the fastest way to learn yours is to line your cover up next to the current bestsellers in your exact category. You'll see the conventions immediately: romance signals the pairing and the heat level, thrillers go high-contrast and ominous with a big author name, SFF shows scope through a scene or an iconic symbol, literary fiction often goes typographic and conceptual, and children's and MG covers put a character with real personality front and center. Meet the convention enough that the reader knows what they're looking at, then give them one reason to pick yours. If there's a book two someday, keep the design consistent so the series reads as a set.

---

7. Print, hardback, ISBNs, and the series page

If you're in a print-leaning genre (kids, MG, illustrated nonfiction, a lot of literary fiction), paperback is table stakes, and the real question is hardback. I'd at least weigh it. Libraries and schools prefer hardback, it survives more handling, and it signals "keeper" to anyone buying a gift. It costs more to make and prices higher, so it's a judgment call, not a must.

On the ISBN, this is where a lot of first-timers quietly give something up. A free KDP ISBN (the 979-8 kind) works fine on Amazon, but it's Amazon-owned, it lists an Amazon-adjacent publisher, and it can make the book harder to find or stock outside Amazon. Buying your own makes you the publisher of record. Where you buy depends on your country:

• United States: Bowker (myidentifiers.com). Pricey for a single, much cheaper in a block of ten or a hundred, so buy in bulk if you'll publish more than once. Check the current price before you commit.
• United Kingdom: Nielsen.
• Australia: Thorpe-Bowker (myidentifiers.com.au).
• Canada: free from Library and Archives Canada, one of the few genuinely free national programs.

There's a public-money angle worth a look too, and most authors miss it. Several countries run a Public Lending Right scheme that pays authors and publishers each year for copies held in public libraries. Australia, the UK, and Canada all have versions, among others. Owning your own ISBN and being the listed publisher is usually what makes you eligible, and a free KDP ISBN generally can't. If you're writing the kind of book that lands in libraries and classrooms, that's real recurring money, so check your own country's rules.

Whatever formats you run, set the series page up cleanly so every format and every future book clusters together.

8. Reviews and launch momentum: your biggest lever

Early reviews and fast early sales are what tell Amazon's system to start promoting you for free. The pattern that keeps showing up in the data: even one or two reviews in the first week lift how many browsers buy, and getting to ten or twenty in the first month can tip you into a tier where Amazon does some of the selling for you. So you build this pipeline before launch, not after.

• Build a launch team now. Your beta readers, your newsletter list, the people who already know the book exists. These are your first reviewers. Line them up before launch day and ask them to post an honest review the day it goes live.
• Send ARCs to the right people. For adult fiction, that's genre reviewers, bookstagram and booktok accounts in your lane, and book bloggers. For kids' books, it's parents, teachers, and school librarians, who review and, more importantly, recommend you to other buyers.
• Use the editorial reviews field. KDP gives you a spot for quotable blurbs from credible readers. Gather these from anyone respected who's read it early.
• Concentrate it. Aim to have reviews landing at or near launch, and try to bunch your sales into a tight window rather than letting them trickle. The concentration is the signal, more than the raw count.

A word on the rules: reviews have to be honest and unpaid, and they come from the reviewer's own buying account. Don't buy reviews or run review swaps that Amazon can pattern-match. Getting caught is worse than launching quiet.

9. Kindle Unlimited, pricing, and pre-order

Kindle Unlimited. Joining, through KDP Select, locks your ebook to Amazon for 90 days and adds page-read income plus a "read for free" badge. Whether that's a great deal or a bad one is almost entirely a genre question, and this is the single biggest genre fork in the whole playbook.

• If you write romance, thriller, or science fiction and fantasy, KU usually earns its keep. Those readers live inside Kindle Unlimited and burn through five or more books a month, so page reads add up to real money, and the borrow counts feed your rank. Romantasy and LitRPG in particular are built on KU right now.
• If you write literary fiction, middle grade, or children's books, hold it loosely. Fewer of those readers are on KU, so the page-read upside is smaller than the hype, and you're giving up the freedom to sell the ebook anywhere else for those 90 days. The wide route (selling on Apple, Kobo, and the rest) often makes more sense.

Either way, KU borrowers won't touch a pre-order, since they're waiting to borrow, not buy, so point your launch-day pre-order push at buyers.

Pricing. Price to your genre's norm, because readers of each genre carry a built-in sense of what a book "should" cost. From the pricing data indie authors track, the rough 2026 bands run like this:

• Romance and urban fantasy: $2.99 to $4.99, with frequent promo dips. High volume is the game.
• Thriller and mystery: $3.99 to $5.99. A big share of top sellers still sit at or below $3.99.
• Science fiction and fantasy: $3.99 and up. These readers tolerate a higher price, and most top-100 fantasy ebooks sell above $3.99.
• Literary fiction: $4.99 to $9.99. Slower promo cadence, a little prestige built into the price.
• Nonfiction: $4.99 to $9.99 for general, and $6.99 to $14.99 for how-to and expertise, where the buyer is paying for the answer.
• Children's and MG ebooks: $2.99 to $4.99. Price it to be an easy yes for a gift, not to squeeze each copy.

Price to convert, not to maximize the take on a single sale, especially at launch when you want volume and velocity.

Pre-order. If you're publishing an ebook, open one. Every sale during the pre-order window lands on release day and stacks into a single spike, which lifts your launch-day rank and trips those momentum signals. Point your buyers (the ones not waiting on KU) at the pre-order so day one hits hard.

10. One myth worth killing: Goodreads

There's a persistent belief that Amazon populates Goodreads for you, since Amazon owns it. It's the opposite. Amazon owns Goodreads but deliberately doesn't feed it, so a new KDP book often sits unlisted until a human adds it. You can add it yourself, or ask in the Goodreads Librarians group to have it added. Do it before launch, get it onto a few relevant genre lists, and have your launch team mark it "want to read." It's free reach you'd otherwise leave on the table.

---

The short list, if you do nothing else

1. Mine Amazon's auto-suggest and lock your seven keywords, choosing a couple to reach extra browse categories.
2. Pick three specific categories per format. The three-slot limit is firm now, so make them count.
3. Set your series metadata, and your reading age if it's a kids' book.
4. Write the description for whoever clicks Buy, in the language of your genre.
5. Build the launch team before launch day and brief them to review, and pre-order, when it goes live.
6. Add the book to Goodreads yourself, and gather your editorial blurbs.
7. Make your two genre calls: Kindle Unlimited, and which formats.
8. Open a pre-order and price to your genre's norm.
9. Launch tight: reviews live at or near launch, sales bunched into a few days.

That's the whole game. None of it is magic, and all of it is doable in the weeks before you hit publish. The book being good is the hard part, and that part's already behind you. This is just making sure the right readers can find it.
