Amazon Ads and Publisher Profit: Understanding the Incentive Gap

You want your books to leave you with more money after costs. You want time to publish the next one. And you want to stop wondering whether your ads are wasting the money you worked to earn.

Amazon has made independent publishing possible on a remarkable scale. Authors can reach readers around the world and print books on demand. They do not need a warehouse full of stock. Ads help readers discover books they might otherwise miss.

Publishers can value all of that while recognising a simple business fact.

Amazon runs a marketplace and sells advertising within it. You run a publishing business and buy ads to support it. Your interests often overlap. But the decisions that serve each business will not always be the same.

Understanding that gap helps you decide where your advertising budget belongs.

Amazon's role is to sell advertising within its marketplace. Your goal is to keep more profit from your books. Those interests can overlap without being closely aligned. Adigy exists to serve your side of that decision. Our long-term success depends on helping you profit.

Amazon has its own business goals

Amazon benefits from a marketplace that attracts readers and publishers. Ads that help readers find relevant books can benefit everyone involved.

Ads also need to provide enough value for advertisers to keep buying them. Publishers who keep losing money have a reason to reduce spending or stop.

Those shared interests matter. Effective advertising is valuable to Amazon as well as to publishers.

But consider the next dollar you might spend.

For Amazon, that dollar buys advertising from its business. For you, it is an expense that needs to earn its place in your publishing plan.

You might spend it to earn profitable sales today. You might invest it in a launch, test a new audience, or introduce readers to a series. The decision should make sense for your books, your finances, and your goals.

Having more ads available does not mean buying more is worthwhile.

Seller data shows why platform interests matter

Amazon's marketplace history gives a concrete example of this tension. In October 2021, Reuters reported that Amazon's private-brands team in India used internal seller data to copy other companies' products. Its investigation drew on internal Amazon documents. Amazon disputed the claims and said its policy barred using non-public, seller-specific data to benefit sellers, including its private brands. Read the Reuters investigation.

In a separate UK case, the Competition and Markets Authority accepted binding commitments from Amazon in November 2023. These included restrictions on using third-party seller data to give its own retail business an unfair advantage. Accepting those commitments was not a finding that Amazon had broken competition law. See the CMA's announcement.

Those cases concern marketplace sellers and retail competition. They do not establish misuse of authors' data in Amazon Ads. They do show why a platform's interests deserve scrutiny. You can value the platform and still insist that your own decisions serve your business.

Ad sales and publisher earnings are different measures

Amazon Ads provides useful measures of campaign performance. One is advertising cost of sales, or ACoS. It is ad spend divided by attributed sales, expressed as a percentage. Attributed sales are the sales Amazon credits to your ads.

ACoS compares your ad spend with that sales value. It does not tell you how much royalty income you kept.

Adigy synchronises your KDP royalty data and combines it with your Amazon ad spend. It calculates the royalties left after advertising, giving it a view of your earnings beyond attributed retail sales. That lets Adigy make advertising decisions informed by your actual royalty income and the cost of earning it. The aim is to improve the money you keep, rather than chase a lower ACoS in isolation.

Consider this illustrative example:

On a small screen, scroll the table to compare the figures.

The campaign generated sales. But under these assumptions, the ads cost more than the royalties from those sales.

Amazon's own guidance says a suitable ACoS depends on margins and campaign goals. You still need to know your book's costs and royalties to judge the result. See Amazon's ACoS guide.

The same distinction applies to bidding. Amazon's dynamic up-and-down bidding adjusts bids based on the chance of a sale. That can help you reach likely buyers. But the chance of a sale alone does not tell you what that sale is worth to your business. See Amazon's dynamic bidding guide.

Our ACoS versus profit guide explains how to compare these metrics with your royalty income.

Start with your publishing goals

Your priorities can change from book to book and over time.

An established standalone title may need to earn a positive return now. A first book in a series may justify a higher cost to attract a reader. That depends on how many readers go on to buy later books. A launch may need a set testing budget before you have enough data to judge it.

Each choice needs clear goals and spending limits.

Royalties minus ad spend shows what remains after that advertising expense. It does not deduct every publishing cost. Total royalties also do not prove that ads caused every sale.

Include editing, covers, software, management fees, and other costs in your wider business review. Later book sales and future reader value can matter too. Test those assumptions against your results.

The question is whether your ads support the publishing outcome you want.

Where Adigy fits

We built Adigy to serve authors and publishers using Amazon Ads. It manages recurring campaign work and brings ad spend together with royalty reports. You choose the books, markets, budgets, and goals. See how Adigy works.

Adigy also automates campaign creation. It can create dozens of campaigns across your chosen books and marketplaces, using your custom inputs. Manual setup means repeating that work for each book and market. Adigy can save many hours a month as you launch books and expand your advertising.

Our purpose is to help you keep more of what your books earn and free your time to build the business.

Sometimes that means finding more opportunities. Sometimes it means reducing bids, removing poor-fit targeting, or spending less. A larger budget makes sense when the extra value justifies the extra cost.

There is experience behind the software too. Adigy grew out of our founder's KDP publishing and advertising agency work. The software began as an internal tool in 2020. That experience informs its strategy and campaign decisions. Read Adigy's story.

The aim is to help you reach sound decisions sooner. You should not have to fund every lesson through your own ad budget. Your books still need their own tests and data. Experience helps guide that process.

Our business interests deserve scrutiny too

Adigy is a business. We charge for our software and want to make a profit.

Our long-term success depends on helping you stay profitable. That means judging our work by what you keep after costs. More clicks, more campaigns, and more ad spend only have value when they serve your goals.

You have a direct reason to care about this alignment: it is your money at stake. Every dollar saved from wasted ads can stay in your business. Every hour returned to you can go towards your next book or improving the ones you already sell.

Our pricing starts at $249 per month. That covers management of up to $2,000 in monthly ad spend. We charge 3.3% of spend above that threshold. Once you pass $2,000, another $1,000 in ads adds $33 to our fee. See Adigy pricing.

You pay our fee whether or not your books make a profit. Above the threshold, more ad spend also increases our revenue. So our interests are not identical to yours in every respect.

Our responsibility is to make the cost clear and help you improve the outcome after paying it. Include our fee when you judge your results. The aim is more money left for you, with less of your day spent managing ads.

What $249 a month needs to earn back

Over a 30-day month, the $249 base fee works out to $8.30 per day.

At an illustrative cost per click of $0.75, that is roughly 11 clicks a day. The exact monthly equivalent is 332 clicks.

Suppose Adigy prevents $8.30 a day of wasted spend while preserving your royalty income. Those savings alone cover the base fee. That money would otherwise have gone to Amazon for ads that did not help your business.

Across an active account, 11 avoidable clicks a day can be a modest amount of waste to find. They need not come from one obvious, costly mistake. Small amounts of poor-fit traffic can add up across books, campaigns, and markets. A manual review can miss them.

For accounts with enough waste, we see covering the base fee this way as an achievable starting point. Our ambition is to add much more value through better advertising and time saved.

Find waste before a click-count rule catches it

A simple cleanup rule might wait for 10, 15, or 20 clicks with no sales before taking action. That can control some spending. But many poor-fit terms can each spend below the threshold. A manual review may miss them too, especially when attention goes to the largest spenders.

Adigy takes a broader approach. It analyses the book's content and positioning, its target audience, and the likely intent behind each available search term. It assesses that term's fit with the book alongside the performance data.

The purchaser and end user can be different people. A parent may buy a workbook for a child. A teacher may choose classroom material. A gift buyer may search for someone else's interests.

Adigy considers who may buy the book, who will use it, and what the buyer needs. A matching keyword alone does not establish a good fit. The tool infers likely intent from the query and book context. It does not know an individual shopper's identity.

A search term may express a need the book does not meet. Adigy can flag that mismatch without waiting for a set number of paid clicks. If the fit looks promising but data is scarce, zero sales alone need not justify blocking it. The aim is to cut waste while preserving useful chances to learn and sell. Read how Negative Oracle evaluates search terms.

This review across the account underpins our confidence in the savings opportunity. Manual reviews and simple rules can leave small, repeated mismatches unnoticed. Assessing each reported term against the book gives Adigy more ways to find them. Avoiding $8.30 a day of waste while preserving royalty income covers the base fee.

Redirecting spend can create value too. Better targeting or bidding may earn more royalties from the same budget. The extra royalties, after any extra ad costs, count towards covering the fee. Moving $8.30 to a different campaign does not itself save $8.30.

Available savings depend on click costs, account activity, and how well your ads already run. A small or efficient account may not contain $249 a month of waste. Time saved and extra royalty income then matter more to the calculation. Include any spend-linked fee above the base allowance too.

Compare the work as well as the price

You may already use a virtual assistant or freelance service. Take an illustrative fee of $50 per book per month, with account updates twice a week. For one book, that costs less than Adigy's base fee. For five books, it adds up to $250 a month.

These are example costs and tasks, rather than typical freelancer rates or a judgement of service quality. Ask what work each fee covers, how the provider makes decisions, and what results follow. Include the time you still spend supervising the work.

Adigy monitors performance and automates recurring changes within the limits you set. Its built-in experience aims to reduce the trial and error you fund yourself.

Include campaign creation in the comparison. A twice-weekly review service may have a different scope from one that also builds dozens of campaigns. Check how much setup work each service leaves with you.

A smaller account can still benefit through better ads, less waste, and less demand on your attention. Catalogue size is one part of the calculation.

Your attention has an opportunity cost

Managing ads yourself costs more than the hours spent in the console. Each session reviewing terms or adjusting bids competes with other work in your business.

Campaign creation adds to that demand. A new book or market may need several campaigns, each with its own setup and targeting. Adigy creates campaigns based on your inputs. You can expand your advertising without building each campaign by hand.

The time you save could go towards your next book or improving an existing one. You could create reader bonuses, develop follow-on offers, build a community, or encourage honest reviews. Those investments can support your business long after you have paid for an ad click.

That is the opportunity cost of managing ads yourself. What else could you achieve with that time and attention? You do not need to assign yourself an hourly rate to see the trade-off.

The worry can also follow you away from the console. Are you missing a promising audience? Is a weak target still spending? Could the account perform better if you knew which changes to make? Those questions can interrupt work even when you are not running campaigns.

Adigy takes on the recurring work so you can review outcomes at an interval that suits you. You keep control of goals and budgets. You gain time and attention for the work of building your business.

The book page affects profit too

Ad performance depends on what happens after the click. A relevant reader still needs a convincing reason to choose your book.

That is why Adigy includes Conversion Compass. It analyses your book page and the competitors readers compare it with. It offers feedback on positioning and ways to improve conversion. Explore Conversion Compass.

The feedback helps you examine your unique selling proposition. This is the specific reason a reader should choose your book. It also helps you assess how well the book's promise fits your target audience.

Those are questions about product–market fit. Does the book address something readers want? Does the page make its value clear?

You can test the suggestions and choose which changes to make to the book, its offer, or its page.

This connects to the incentive gap. Selling another click earns ad revenue for the platform. Helping you make better use of existing clicks can improve your return without raising your ad budget. We support that goal through campaign automation and feedback on what readers find after the click.

Adigy wins when you profit

Amazon provides valuable tools for publishing books and reaching readers. Adigy aims to help you use those tools to improve your profitability. It automates recurring ad work, draws on publishing experience, and helps you find ways to make your books more compelling.

Your reason to use Adigy is the difference it can make to your own business. Less money lost to poor-fit clicks. More value from the budget you choose to spend. More time to create books and offers that keep earning for you.

Adigy wins by helping you win: more profit from your books and more time to build your business. Your profit is the outcome our work should serve. Our long-term success depends on yours.
