Ready
The book has
A genre cover that gets clicks, a blurb that converts, 10 or more reviews at 4 stars or above, a price that leaves room to profit, and ideally a series or something to sell after the book.

Book marketing servicesDone-for-you ads on Amazon and Meta.
Free Ads Readiness Check first.
Ads multiply what a book already converts. So before you pay anything, we check your cover, blurb, reviews, price and categories, work out your real break-even for each format, and tell you in writing whether ads are likely to pay back.
Then we build, test and run the campaigns for a flat monthly fee, and send you a plain-English book profit report every month.
- No setup fee, no percentage of ad spend
- Ad money goes from your card straight to Amazon and Meta
- Billed monthly, cancel any month
Every book is welcome
We take every book and every genre, and tell you the truth about it first.
The free Ads Readiness Check ends in one of three written verdicts. Nobody is turned away: you see the verdict before you pay, and you decide.
Fix first
The book has
One or two gaps: a weak cover or blurb, fewer than 10 reviews, the wrong categories, or a Look Inside without a hook.
What we tell you
What to fix, by HMD or yourself, and that ads will waste money until it's done.
Ads unlikely to pay back
The book has
A single literary or poetry title with no platform, a low-content book, a permanent 99p price, or a break-even under about 20%.
What we tell you
In writing: ads will probably cost more than they earn. If you still want to go ahead, we run them carefully on the smallest budget.
Which ads for which book
We never sell every platform by default.
The Readiness Check picks the platforms that fit your book, and the package follows from that.
Series romance, romantasy, fantasy, thriller, mystery, sci-fi
- Amazon
- Yes
- Meta
- Yes
The genres where readers buy one book after another.
Non-fiction with a course, coaching or service behind it
- Amazon
- Yes
- Meta
- Yes, to an email sign-up
The return comes from what readers buy after the book.
Standalone genre fiction
- Amazon
- Yes
- Meta
- Only with a free-chapter sign-up
One book rarely pays back cold ads on its own.
Children's picture books
- Amazon
- Yes, carefully
- Meta
- Yes, aimed at parents
Low prices make break-even tight.
Literary fiction, poetry, memoir with no platform
- Amazon
- Only if you still want it, smallest budget
- Meta
- No
We say in writing that ads will probably not pay back, and suggest launch, PR and reviews instead.
Low-content books, or anything stuck at 99p
- Amazon
- No
- Meta
- No
The royalty leaves no room to pay for clicks.

Our promises
We promise how we work, not sales numbers.
A sales guarantee is the classic sign of a book marketing scam. These are the six things we do promise.
Your money stays yours
Ad spend goes from your card straight to Amazon and Meta. We never take a percentage of it, so we gain nothing by spending more.
A spending cap you set
Daily caps on every platform, and a monthly ceiling in writing. We cannot spend past it.
A break-even line, worked out per book
Agreed before launch. Any campaign above it for 14 days, with no sign of improving, gets paused.
An honest Day-45 verdict
If ads cannot pay back for your book, we tell you in writing and recommend stopping, even though that loses us the client.
Cancel any month
Billed monthly, with no minimum term. Cancel before your next billing date by emailing support@hmdpublishing.com.
You own everything
Ad accounts, creatives, audiences and your email list stay yours if you leave.
Reviews
What authors say about working with us
We do not yet have named reviews specific to book marketing, so these are verified HMD Publishing clients from our other services. They are shown here as proof of how we work, not as book-marketing customers.
“This team was amazing. I cannot say enough about them. When I tell you how much they have poured into my life, you wouldn’t believe it. They were encouraging, supportive, they were patient,, and they were very respectful to what I was trying to figure out during this process. I have another project coming up, they are the one for me. I felt that we were so aligned, I was at peace when I talked to anyone member of the team. At the end of any conversation I have had with them, they all always end with some type of encouraging words. Sorry, I didn’t mean to be this long on here, but I just had to share the amazing work this team is doing. You can feel they do care when they sent an email. I think God knows exactly who I needed for this project, and He gave them. The book is now published, great job. Thank you, thank you. May God continue to bring people to you because you are doing an amazing job through your work. Lucie”
LTP HopeAuthor of When Goodbye Comes Too Early: Learning To Breathe Again Through Love and Loss“I've worked with HMD Publishing on numerous occasions. Clearly that shows my satisfaction with their level work. I will most certainly work with them in the future as well. They are patient, and attentive to my specific needs and as always it was a pleasure.”
Jamaal C. BoyceAuthor of Investing Is The Best Thing: An Introductory Guide to the World of Investing for Teenagers and Their Parents“Very professional and easy to work with.”
Avraham NacherAuthor of Geshara Mazes: Where Geniuses Get Lost“I am blown away by the quality of work and communication. My one regret about this entire interaction is that I did not find HMD Publishing _before_ I released my book. If you're thinking about hiring their services, stop thinking and just do it. You will not be disappointed.”

How Book Growth works
You fill in one form, share ad-account access, approve a monthly budget and read a monthly report. We do the rest.
Step 1
Free Ads Readiness Check
Apply with the form above. Within 5 working days we score your cover, blurb, Look Inside, reviews, price, categories and series page, work out your real break-even for each format, and send a written verdict.
Step 2
Fix first, if needed
Anything that would waste ad money is fixed before launch. You can fix it yourself, or ask HMD to (cover, blurb, A+ Content, categories, editing).
Step 3
Build, in the first 2 weeks
Keyword and competitor research, campaign build, ad creatives and copy, tracking, and daily spend caps on every platform. You approve the plan and the creatives before anything goes live.
Step 4
Test, days 15 to 45
Small budgets across many targets to find what converts. Campaigns above your break-even line are cut; the ones below it get more budget.
Step 5
Day-45 verdict
A plain written call: scale, adjust or stop. If the data says ads cannot pay back for this book, we say so and recommend pausing.
Step 6
Grow and report, month 2 onwards
Weekly changes, new creatives every month, new marketplaces and formats. A short weekly update and a monthly book profit report: royalties (including Kindle Unlimited), ad spend, our fee and the net result.
FAQ
Questions authors usually ask before they commit.
Clear answers on timeline, scope, rights, revisions, and what happens after checkout.
What is HMD Book Growth?
Book Growth is our done-for-you book ads service. Amazon Engine runs Amazon ads for one series or up to three books. Reader Engine adds Meta (Facebook and Instagram) ads, a reader sign-up page and free-chapter email capture, for up to two series or six books. Both are a flat monthly fee.
What is the free Ads Readiness Check?
Before you pay anything, we review your book's cover, blurb, Look Inside, reviews, price, categories and series page, and work out your real break-even for each format. Within 5 working days you get a written verdict: ready, fix first, or ads unlikely to pay back. It is free, and you decide what to do next.
Do you accept every book?
Yes. We take every book and every genre. The Readiness Check tells you honestly how likely ads are to pay back for your book. If they probably won't and you still want to go ahead, we run them carefully on the smallest budget.
Who pays for the ads?
You do, directly. Ad spend goes from your own card straight to Amazon and Meta, never through us, and we take no percentage of it. The packages section above shows the starting ad budget for each package, and you set the cap.
Is there a setup fee or a minimum term?
No setup fee and no minimum term. Book Growth is billed monthly and you can cancel any month, before your next billing date, by emailing support@hmdpublishing.com.
Will Book Growth guarantee sales?
No, and you should be wary of anyone who does. We guarantee how we work: your spending cap, a break-even line agreed before launch, an honest Day-45 verdict and reports you can check against your own KDP and ad dashboards.
Who owns the ad accounts and creatives?
You do. The ad accounts, creatives, audiences and your email list stay yours if you leave.
How do I market my book?
Start with the book itself: cover, blurb, reviews, price and categories. Ads only work as well as the page they send readers to, which is why every Book Growth author starts with the free Ads Readiness Check before any ad money is spent.
