Amazon Ads analytics for KDP self-publishers
Understand your Amazon Ads.
Book by book.
PublisherBoost brings your advertising data together. See which search terms generate orders, where spend produces no orders and how your figures develop after a change.
For Sponsored Products · No automated campaign changes
Everything in context
Which ads bring orders — and at what cost?
A search term appears in several campaigns. A single row only shows part of its performance. To make a decision, you need both: the totals for your book and each campaign’s contribution.

Frequently asked questions
Clear answers are part of the product.
Who is PublisherBoost for?
KDP self-publishers who use Sponsored Products for their own books and want to understand their advertising data. The analysis connects books, campaigns, ad groups, targets and search terms.
Does PublisherBoost change my campaigns?
No. PublisherBoost analyses advertising data and provides recommendations. You decide whether to make a change and apply it yourself in Amazon Ads.
How are recommendations generated?
Recommendations use defined rules, your advertising data and your settings, including your ACoS threshold for each book and marketplace. The figures and date range explain each recommendation. Missing or incomplete data can limit what you can conclude.
What does ACoS mean?
ACoS is ad spend divided by attributed advertising sales. €41 spent against €100 in advertising sales means 41% ACoS. With a threshold of 30%, this is 11 percentage points above the threshold. ACoS is not a measure of profit.
Is my organic rank tracked automatically?
No. You enter organic rank manually with its date and source. Keyword tracking lets you review it alongside advertising data and recorded changes. A change in rank or ACoS does not prove the effect of one adjustment.
Can I add other users or clients’ advertising accounts?
Each login is intended for one adult and one advertising account of their own. For a business subscription, the named user works with an account belonging to that business. Shared logins, additional team members and clients’ advertising accounts are not included.
What happens after three or twelve months?
Unless cancelled, the subscription continues on an ongoing basis at €29.95 per monthly billing period. It does not start another fixed three- or twelve-month term. You may cancel at any time, effective at the end of the current subscription period. Statutory rights are unaffected.
Does PublisherBoost promise more sales or a better rank?
No. The software helps you interpret data and keep track of decisions. Sales, profit, advertising costs and rank depend on many factors. We do not guarantee a particular outcome.
Your advertising decisions. Our responsibility for the product.
PublisherBoost is developed and operated by Prasser & Schmidt GbR in Röbel/Müritz, Germany. Our aim is to make advertising data easier to understand and help you keep track of your own decisions.
