Most indie publishers never crack Amazon Ads. Not because they aren’t smart — because running ads well is a full-time craft of its own, and you already have one: writing and publishing books. Book Midas exists to take that second job off your desk — whether you’ve published one book or a hundred. You keep telling stories. We make sure the right readers find them.
How it works
Four steps, then it runs on its own.
Connect your Amazon Ads.
You grant access once, through Amazon’s own secure sign-in. Nothing else to install, no spreadsheets, no API keys to wrangle.
We learn how each book earns.
We work out what each paperback really earns — the true royalty behind its price, the list price minus Amazon’s print cost, not the sticker on the cover. One book or a hundred, the math is done title by title. Most ad tools aren’t built to look at any of this.
We run the ads. You keep writing.
Book Midas sets bids, finds the keywords that actually sell each book, and trims the spend that doesn’t — every day, without you touching a thing.
You stay in control.
Set a budget ceiling we can never cross. See a plain-English reason for every change we make. Pause the whole thing in one click, any time.
Why books need their own tool
General ad tools are blind to how books make money.
A generic ads tool sees
- One number: did a click lead to a sale?
- It cuts keywords that don’t show a direct sale.
- It will advertise any listing — even one that can’t convert.
Book Midas sees
- Each paperback’s true royalty — the list price minus print cost, not the cover sticker.
- Whether the listing can actually convert a click — before a cent is spent advertising it.
- So it keeps the ads that earn against that true royalty — and cuts the ones that don’t.

Questions
In case you were wondering.
Do I need to know anything about advertising?
No. That’s the point. If you can publish a book on Amazon, you can use Book Midas. We don’t ask you to learn ad jargon, build campaigns, or read dashboards full of acronyms — we handle all of it and tell you what’s happening in plain words.
I only have one book. Is this for me?
Yes — maybe especially for you. Book Midas works book by book: each title gets its own economics, its own campaigns, and its own decisions. There’s no minimum number of books, no minimum spend, and no setup fee. One book with a fair budget is exactly how most publishers start.
Which formats do you advertise?
Paperback. It’s the format with the cleanest economics and the strongest ad returns, so it’s where we focus — and where we get you the best results. When you connect, you give us your paperback ASIN; that’s the one we advertise.
Is my data and my account safe?
Yes. You connect through Amazon’s own secure sign-in — we never see your Amazon password. Your access is stored encrypted, used only to manage your ads, and you can disconnect it at any time. We never share it with anyone.
What will it cost?
10% of your ad spend, with spend above $5,000 a month billed at 5%. No base fee, no minimum, no setup cost. Billed monthly after the fact, on spend we actually managed.
