Amazon Ads manager for authors & publishers
I'm Johnny Wang. I've been self-publishing on Amazon KDP since 2010, with more than 3,000 books published, and I've managed Amazon Ads since 2016. I build and run Sponsored Products, Sponsored Brands and Sponsored Display campaigns around the number that matters for a book: your break-even ACoS.
Services
I set up new ad accounts from scratch or take over campaigns that are spending too much. Each campaign type has a different job, so each book gets the mix that fits its price, genre and royalty.
Your book in Amazon search results and on other books' product pages. Most ad-driven book sales come from here, so this is where I start: auto campaigns to discover search terms, then manual campaigns on broad, phrase and exact keywords and on competing ASINs.
Shows in: shopping results and product pages on Amazon, Kindle and Goodreads
A headline ad that features several of your books under a custom message, or one book in a video ad. It works best for series and authors with more than one title, where a reader who finds one book can find the rest.
Shows in: shopping results and product pages, as image or video ads
Reaches readers based on the books and categories they browse, including people who viewed your book and didn't buy. I use it to defend your own product pages and to stay in front of readers who are close to a purchase.
Shows in: product pages, on and off Amazon. Availability depends on your account type; I confirm it in the audit.
Also available: publishing setup on Amazon KDP and wider distribution through IngramSpark, Lulu and Draft2Digital, including metadata, categories and keywords.
How I set targets
ACoS (advertising cost of sales) is what you spend on ads divided by the sales those ads bring in. When ACoS is lower than the share of the price you keep as royalty, the ad pays for itself. I set a target for each book from that number before spending anything.
break-even ACoS = royalty per sale ÷ list price
Kindle Unlimited page reads earn royalties too, but they don't count toward ACoS. I track those separately, so a campaign that looks expensive on paper isn't switched off while it's actually making money.
Process
Send me your book links. I review price, royalty, categories, the product page and any ads already running.
Keywords, categories and competing ASINs that readers of your book already buy.
Campaigns go live with a daily budget cap you approve. The ad account stays yours.
Every week: bid changes, new negatives, and winning search terms moved into exact-match campaigns.
A monthly report in plain English: what was spent, what it earned, and what changes next.
Results
The last 30 days of Sponsored Products in an Amazon Ads account I manage, taken straight from the ads console. The account runs more than 1,200 Sponsored Products campaigns.
About
I published my first book on Amazon KDP in 2010 and I'm still publishing today. My team and I have now published more than 3,000 books.
I've published through Amazon KDP, IngramSpark, Lulu and Draft2Digital, so I know how each platform handles formats, pricing and distribution. I started managing Amazon Ads in 2016, and the campaigns I run for clients follow the same process I use on our own books.
Since 2017 I've also taught Amazon KDP self-publishing in Taiwan, through seminars and workshops for new authors and publishers. I work with clients in English and Mandarin Chinese.
My book
A practical handbook on self-publishing ebooks on Amazon, written in Chinese for people who want their expertise seen by more readers, earn royalty income, and help others through their books.

No. You invite me as a user from your Amazon Ads account settings, and you can change or remove my access at any time. The account, the campaigns and the data always stay yours.
It depends on how much of the price you keep. A $4.99 ebook at the 70% royalty rate can break even near 70% ACoS, while a paperback with high printing costs might break even at 25%. I calculate a target for each book and manage to it, rather than chasing one number for everything.
There's no fixed minimum. At the start, the budget needs to be large enough for each campaign to collect clicks and data for a few weeks. We agree on a daily cap before anything goes live, and I stay inside it.
The first two to four weeks are mostly about collecting data: which search terms convert and which only spend. Most of the improvement comes after that, from weekly optimization. Expect a clear picture by the end of the first month.
Yes. I start with an audit of your current campaigns, keep what's working, pause what's wasting money, and restructure the rest so it's easy to manage and report on.
Spend, sales, orders, ACoS and ROAS for each book and campaign, Kindle Unlimited reads where they apply, and a short list of what I changed and what I plan to test next.
Yes. I can set up your book on Amazon KDP and distribute it more widely through IngramSpark, Lulu and Draft2Digital, including categories, keywords and metadata, so it's ready to advertise from day one.
