A Step-by-Step Guide to Advertising Your Books Without Wasting Your Royalties
By Madi Preda
Part Two of the Amazon Advertising for Authors Series
So, you’ve decided to try Amazon advertising.
You’ve read about keywords, targeting, sponsored books, impressions and clicks. You understand that advertising might help readers discover your book.
You feel reasonably confident.
Then you open the Amazon Advertising dashboard.
Suddenly, you’re confronted with campaign types, bidding strategies, targeting options, placement adjustments and enough unfamiliar terminology to make you seriously consider taking up gardening instead.
Don’t worry. We’re going to make this practical.
In my previous article, Amazon Ads for Authors: A Practical Guide for Every Major Book Genre, we explored how Amazon advertising works and why different genres need different strategies.
Today, we’re going further.
We’re going to build actual advertising campaigns, choose budgets, select keywords, calculate bids and learn how to decide whether our advertising is working.
I’ll use realistic examples throughout, including historical fiction, romance, thrillers, children’s books and nonfiction.
And because most independent authors don’t have unlimited marketing budgets, we’ll begin with something particularly important:
How to advertise without spending more than you can afford.
1. First, Understand What You’re Actually Paying For
Amazon Sponsored Products advertising generally operates on a cost-per-click model.
That means you don’t pay simply because someone sees your advertisement.
You pay when someone clicks it.
Let’s imagine you’ve written a historical novel.
You create an advertisement, and Amazon displays your book to readers searching for historical fiction.
During one day:
- 2,000 people see your advertisement.
- 20 people click it.
- Your average cost per click is €0.25.
- Two readers purchase your book.
Your advertising cost is:
20 clicks × €0.25 = €5
If your book sells for €12.99, Amazon may report approximately €25.98 in attributed sales.
At first glance, that sounds wonderful.
You spent €5 and generated almost €26 in sales.
But there’s a catch.
Amazon’s advertising sales figures are not the same as your author royalties.
You don’t receive the entire selling price.
For a paperback, printing costs and royalty calculations reduce the amount you actually earn.
For an ebook, your royalty depends on the applicable royalty option, delivery fees, taxes and other conditions.
Therefore, before advertising, we need to establish how much we can afford to pay for each sale.
2. Calculate Your Break-Even Advertising Cost
This is probably the most important calculation in this entire article.
Imagine your paperback sells for €12.99.
Your actual royalty, after Amazon’s applicable calculations and printing costs, is €3.50.
That means:
If advertising costs €3.50 to generate one additional sale, you’ve reached your approximate break-even point.
Spend less, and you may make a profit.
Spend more, and you’re potentially losing money on that sale.
Now imagine you receive €3.50 per book and want to keep at least €1.50 profit.
Your maximum advertising cost per sale would be:
€3.50 − €1.50 = €2
This gives you a clear target.
Instead of blindly bidding against other authors, you know what your book can financially support.
A Simple Author Advertising Formula
Maximum advertising cost per sale = Royalty per book − Desired profit per book
For example:
Kindle ebook€4.99€3.20€2.00
Paperback€12.99€3.50€2.00
Hardcover€19.99€4.50€2.50
These are illustrative figures, not Amazon royalty estimates. Your actual royalties depend on marketplace, format, printing costs, taxes and other factors.
The lesson?
Never choose your advertising budget without understanding your royalties.
One important qualification: if you have a series, advertising Book One may generate additional royalties from later books. Kindle Unlimited page reads can also affect your overall return. Those earnings should be evaluated separately rather than assumed to appear in the campaign’s attributed sales.
3. Where to Find Amazon Advertising
If your books are published through Kindle Direct Publishing (KDP), you can normally begin from your KDP Bookshelf.
Step 1: Log in to KDP
Open your Kindle Direct Publishing account.
Step 2: Find the Book
Navigate to your Bookshelf and locate the book you want to advertise.
Step 3: Select Promote and Advertise
Depending on the current KDP interface, you’ll find advertising options associated with your book.
Choose the advertising option and the marketplace in which you want to advertise.
Step 4: Open the Advertising Console
You’ll be directed to Amazon Ads.
You can also access the advertising console directly if your account is already configured.
Step 5: Create a Campaign
Look for the option to create a new advertising campaign.
For this tutorial, we’re focusing on:
Sponsored Products
This is generally the most straightforward starting point for authors.
Important: Amazon periodically changes its interface. Button names, eligibility requirements and available settings may differ slightly by country and account.
4. Choose the Right Marketplace
This decision deserves more attention than it usually receives.
Amazon operates separate advertising marketplaces.
For example:
- Amazon.com — United States
- Amazon.co.uk — United Kingdom
- Amazon.de — Germany
- Amazon.fr — France
- Amazon.it — Italy
- Amazon.es — Spain
Not every advertising marketplace or feature is available to every account.
Your campaigns, budgets and results are managed according to the marketplace you select.
A €5 daily budget in a euro-denominated marketplace is not the same currency as a $5 budget on Amazon.com.
Also remember that readers in different countries may respond differently to the same book.
An Irish historical novel might attract readers in Ireland, Britain, the United States, Canada and Australia.
But that doesn’t mean you should advertise everywhere immediately.
My suggestion for beginners: start with one marketplace, learn from the results and expand gradually.
Choose a marketplace where your book is available and where you have good reason to believe there is reader demand.
5. Campaign One: Automatic Targeting
This is where I would begin.
Automatic targeting allows Amazon to identify potential advertising opportunities based on information about your book and shopping activity.
It is particularly useful for discovering keywords and products you might not have considered.
Step-by-Step Setup
Step 1: Create a Sponsored Products campaign.
Step 2: Give it a recognisable name.
For example:
THE STRAND | AUTO | UK | OCT 2026
A good campaign name tells you:
- Which book you’re advertising.
- Which targeting method you’re using.
- Which marketplace you’re advertising in.
- When the campaign began.
This becomes extremely useful once you’re managing multiple books.
Step 3: Set your daily budget.
For a cautious beginner, consider the equivalent of €3–€5 per day in your marketplace currency.
Remember that a daily budget is a spending control, not a guaranteed or fixed daily charge. Amazon may spend differently on individual days under its applicable budget rules.
Step 4: Select automatic targeting.
Amazon will use its systems to identify potential matches.
Step 5: Choose your bidding strategy.
For an initial controlled experiment, consider:
Dynamic bids — down only
With this strategy, Amazon can lower your bid when it estimates that a conversion is less likely.
This doesn’t guarantee profitability, but it can be a more conservative starting point than allowing bids to increase.
Step 6: Enter your starting bid.
For illustration, let’s start with:
€0.20 per click
This is a test bid, not a recommended market rate.
Some books and marketplaces may receive little or no traffic at this level.
Others may attract useful impressions.
Step 7: Review and launch.
Your first campaign is running!
Now resist the temptation to change everything after twelve minutes.
6. Understanding Automatic Targeting Groups
Depending on the campaign interface, Amazon’s automatic targeting may be organised into four groups.
Close Match
Amazon may show your book for searches closely related to it.
For example, a historical novel set in Ireland might appear for searches involving Irish historical fiction.
Loose Match
Amazon may explore searches that are more broadly related.
This can discover opportunities, but it may also generate less relevant traffic.
Substitutes
Your advertisement may appear around products shoppers could consider as alternatives.
For example, someone viewing another historical novel might see yours.
Complements
Amazon may match your advertisement with products that complement your advertised book.
These relationships aren’t necessarily obvious to an author.
Should You Use Different Bids?
Once you have data, yes.
For example:
Close match€0.25
Loose match€0.15
Substitutes€0.20
Complements€0.10
These figures are merely starting experiments.
The actual performance of your book should determine future bids.
7. Campaign Two: Manual Keyword Targeting
Now we’re going to take more control.
Instead of allowing Amazon to choose all the targeting opportunities, we’ll supply specific keywords.
This is where understanding your genre becomes essential.
Create another Sponsored Products campaign.
Give it a name such as:
THE STRAND | KEYWORDS | UK | OCT 2026
Select manual targeting and then keyword targeting.
For a beginner, I recommend separating experimental keywords from proven keywords once you have enough data.
Initially, you might use 15–25 carefully selected keywords.
Let’s look at some examples.
8. Historical Fiction: A Complete Keyword Example
Imagine you’ve written a historical novel set in Ireland, exploring family secrets, adoption and the experiences of women in the twentieth century.
Your initial keyword list might include:
Irish historical fictionPhrase€0.25
Historical fiction IrelandPhrase€0.25
Irish family sagaPhrase€0.20
Historical novels about womenPhrase€0.20
Irish women’s fictionPhrase€0.20
Mother and baby home fictionExact€0.20
Irish social history novelsPhrase€0.15
Historical family secrets novelPhrase€0.15
Twentieth century Irish fictionPhrase€0.20
Emotional historical fictionBroad€0.15
These are suggested keyword experiments, not verified high-volume searches.
Some may generate no impressions.
That’s perfectly normal.
The objective is to discover which phrases Amazon shoppers actually use and which ones produce sales.
What I Would Avoid
I wouldn’t begin with a very large bid on the single keyword:
Books
Nor would I automatically target:
Historical romance
unless the novel genuinely fits that genre.
The closer the keyword is to your actual book, the more promising the potential audience.
9. Romance: Campaign Example
Romance authors have a major advantage.
Readers frequently search for specific romantic situations and tropes.
Imagine you’re advertising a contemporary romance involving two people finding love again later in life.
You could test:
Second chance romancePhrase
Later in life romanceExact
Mature romance novelsPhrase
Contemporary romanceBroad
Emotional romance novelsPhrase
Love after 50 fictionPhrase
Small town romancePhrase
Women’s romantic fictionPhrase
Romantic comedy booksExact
But there’s an important detail.
Only target tropes genuinely present in your book.
If your novel is heartbreaking and serious, targeting romantic comedy may attract the wrong readers.
Likewise, if your book contains no small-town setting, that keyword probably isn’t appropriate.
A click from the wrong reader is still a paid click.
Romance Bidding Example
Start with a conservative bid such as €0.20–€0.30 on your most relevant keywords.
Use lower bids for broad exploratory keywords.
After collecting meaningful data, consider increasing bids on targets that repeatedly generate profitable sales.
10. Thriller and Crime: Campaign Example
Thriller readers often know what kind of suspense they enjoy.
Imagine you’ve written a psychological thriller involving a missing woman and disturbing family secrets.
Your initial keywords might include:
- Psychological thriller
- Domestic suspense
- Missing woman thriller
- Family secrets thriller
- Dark psychological suspense
- Female protagonist thriller
- Mystery suspense novel
- Psychological crime fiction
- Twisty thriller
- Suspense books for adults
You might begin with a €0.20 bid on exploratory keywords and €0.25–€0.30 on the strongest matches.
Again, these aren’t market benchmarks.
They’re controlled test values.
A Particularly Useful Thriller Strategy
Target comparable books.
If a reader is viewing a novel involving missing persons, family secrets and psychological suspense, your book might be a relevant alternative.
But don’t target every bestseller indiscriminately.
A police procedural and a domestic psychological thriller can have very different audiences.
11. Children’s Books: Campaign Example
Children’s-book advertising requires a slightly different approach.
The child may read the book, but the parent, grandparent, teacher or gift buyer often makes the purchase.
Imagine you’ve written a picture book about a nervous little dog learning to be brave.
You might test:
Picture books about courageEmotional learning
Books for 4 year oldsAge-based shopping
Children’s books about confidencePersonal development
Dog books for childrenSubject interest
Bedtime stories about animalsReading occasion
Books about overcoming fearEmotional learning
Illustrated books for kidsFormat
Children’s friendship storiesTheme
Age-based targeting can be especially important.
A picture book for preschoolers should not be advertised as though it were a middle-grade adventure novel.
Budget Consideration
Children’s books may have relatively small royalties per copy.
That means you need to be particularly careful with cost per sale.
If you earn €2.20 per book, paying €4 to acquire one sale is difficult to sustain unless you have additional, measurable revenue.
12. Nonfiction and Self-Help: Campaign Example
Now imagine you’ve written a practical guide for women navigating midlife.
Your book discusses confidence, healthy habits, reinvention and finding renewed purpose.
Instead of advertising simply:
Self-help books
you could test:
- Confidence after 50
- Reinventing yourself after 50
- Personal growth for women
- Midlife self-help books
- Finding purpose after 50
- Healthy aging for women
- Life after menopause
- Positive aging books
- Women’s personal development
- Starting over in midlife
Why These Keywords Matter
Nonfiction readers often search for answers.
They’re not necessarily looking for a particular author.
They’re looking for a book that addresses a problem, aspiration or life stage.
This is why nonfiction subtitles are so important.
A clear subtitle helps readers understand the book’s value before clicking.
In nonfiction advertising, clarity frequently matters more than cleverness.
13. Campaign Three: Product Targeting
This is one of my favorite strategies for authors because it is based on a simple idea:
Find books your ideal reader already likes.
Instead of targeting search phrases, you target relevant products.
Amazon identifies individual products using ASINs.
ASIN stands for Amazon Standard Identification Number.
Every book listing has one.
How to Find an ASIN
Open a book’s Amazon product page.
Look for its ASIN in the product details or page information.
Copy it.
Then return to your advertising campaign.
Create a Sponsored Products campaign using manual targeting.
Choose product targeting.
Depending on the interface, you can select categories or enter individual products.
How to Choose Books to Target
Imagine you’re advertising a historical novel about women’s lives in twentieth-century Ireland.
Search Amazon for similar novels.
Look for books that share:
- Historical period
- Geographic setting
- Emotional themes
- Reader expectations
- Narrative style
Choose perhaps 10–20 highly relevant titles for an initial experiment.
Don’t worry if they aren’t all bestsellers.
A moderately successful book with a closely aligned audience may be a better target than an enormous bestseller with a very broad readership.
Product Targeting Example
Campaign name:
IRISH HISTORICAL NOVEL | PRODUCTS | UK
Starting budget:
£3–£5 per day, if affordable.
Illustrative bid:
£0.15–£0.25.
These bids may need adjustment depending on competition and results.
The objective is to discover which comparable books produce meaningful engagement and sales.
14. How to Build a €5-a-Day Advertising Plan
Now let’s put everything together.
Suppose your total advertising budget is approximately €5 per day.
That’s around €150 over a 30-day period.
Rather than creating numerous campaigns that compete for a very limited budget, I would start with two.
Automatic discovery€2
Manual keywords€3
Total€5
Run these campaigns long enough to gather useful information.
Once you’ve identified promising keywords, you can reallocate some of your budget towards product targeting.
Who Is This Plan For?
Authors who:
- Are advertising for the first time.
- Have one or two books.
- Want to learn without committing a large budget.
- Need to control spending carefully.
Remember: campaign budgets are spending limits, not guarantees that every euro will be spent or that the combined total will be identical every day.
Amazon’s applicable daily-budget policies can also permit spending fluctuations.
15. The €10-a-Day Plan
With a larger budget, you can test more targeting methods simultaneously.
Automatic targeting€3
Manual keywords€4
Product targeting€3
Total€10
This gives you three sources of information.
Automatic targeting helps discover opportunities.
Manual keywords test reader searches.
Product targeting tests comparable-book audiences.
Over 30 days, the combined nominal daily budgets amount to approximately €300.
That is a meaningful investment for an independent author.
Only commit to it if you can afford the potential expenditure.
16. The €20-a-Day Plan
At this level, you have more room to separate different experiments.
Automatic targeting€4
Broad keyword discovery€3
Phrase keywords€4
Exact keywords€5
Product targeting€4
Total€20
The nominal 30-day total is approximately €600.
However, I would not recommend starting at this level merely because you can afford it.
Higher spending doesn’t automatically mean better results.
If your cover, description or targeting isn’t converting, increasing your budget can simply accelerate your losses.
Scale what works. Don’t scale what you hope might work.
17. How to Choose Your Starting Bids
Amazon may display suggested bids or bid ranges when you set up campaigns.
These can provide useful context about competition.
However, suggested bids are not guarantees of sales or profitability.
Suppose Amazon suggests a bid of €0.65.
Your calculations indicate that you can only afford around €0.25 per click.
You do not have to accept the suggestion.
You can start lower.
You may receive fewer impressions, but you are protecting your budget.
A Simple Bid Calculation
Imagine:
Your royalty per sale: €3.50.
Your expected conversion rate: 10%.
That means approximately one sale for every ten clicks.
Your approximate break-even CPC would be:
€3.50 ÷ 10 = €0.35
If you want to retain some profit, your target CPC should be lower.
But remember that a 10% conversion rate is only an assumption until your own advertising data supports it.
Your actual results may be considerably better or worse.
18. What Happens After You Launch?
Now comes the difficult part.
Waiting.
You may be tempted to check your advertising dashboard every fifteen minutes.
You may discover that you have become emotionally attached to the impressions column.
You may even celebrate your first click.
Then remember that you’ve just paid for it.
Welcome to author advertising.
The key is to avoid making major decisions based on tiny amounts of data.
Instead, create a simple monitoring routine.
19. Your First Seven Days
During the first week, focus on basic campaign health.
Check whether:
- The campaign is delivering impressions.
- The budget is being used.
- The average CPC is affordable.
- The targeting appears relevant.
- Any sales are being attributed.
Don’t panic if you have no sales after three clicks.
Three clicks tell you almost nothing.
Equally, don’t ignore a campaign that is rapidly spending money on clearly irrelevant traffic.
Your aim is to give the system room to gather data while protecting your finances.
20. How to Read Your Results
Let’s examine three fictional campaigns.
Automatic50€12.50€39.0032.1%
Manual keywords40€10.00€65.0015.4%
Product targeting35€10.50€13.0080.8%
Which campaign is best?
At first glance, manual keywords.
But we need to look deeper.
Automatic Campaign
It has produced sales and may be discovering useful search terms.
Keep investigating.
Manual Keyword Campaign
This looks promising.
Examine which individual keywords generated the sales.
Those may deserve more attention.
Product Targeting Campaign
This is potentially expensive.
But before switching it off, examine whether a few product targets are responsible for most of the wasted spending.
You may be able to remove weak targets while retaining useful ones.
Also compare advertising cost against royalties, not just attributed retail sales.
A low ACOS isn’t automatically profitable.
21. The Search-Term Report: Where the Real Learning Begins
This report is one of the most valuable tools available to advertisers.
It shows the shopping searches or targeting matches associated with your advertising activity.
Let’s imagine your campaign reveals the following:
Irish historical fiction20€4.802
Irish family saga15€3.301
Free Irish ebooks18€4.500
Historical novels about women12€2.402
What can we learn?
Irish historical fiction is producing sales.
Irish family saga may deserve further testing.
Free Irish ebooks appears poorly aligned with a paid book.
Historical novels about women looks promising.
Now we can make decisions based on evidence.
22. Move Winning Keywords Into Exact Match
Suppose your automatic campaign discovers that:
Historical novels about women
generates consistent sales at an affordable cost.
Create or update a manual exact-match campaign.
Add that keyword.
For example:
[historical novels about women]
The brackets here are simply a way of illustrating exact-match targeting; enter the keyword normally and select the exact match type in Amazon’s interface.
Start with a controlled bid.
Monitor the results.
If it continues to generate profitable sales, you can consider increasing the bid cautiously.
You have now moved from discovery to deliberate targeting.
This is one of the most useful habits an author can develop.
23. Negative Keywords: Stop Paying for the Wrong Readers
Imagine your historical novel is appearing for:
Free historical romance ebooks
Your book isn’t free.
It isn’t primarily a romance.
And the clicks aren’t converting.
This is a good candidate for negative targeting.
Depending on the targeting options available, you may use negative exact or negative phrase keywords.
Negative Exact
Blocks the specific search term under Amazon’s matching rules.
Negative Phrase
Blocks searches containing the negative phrase under Amazon’s matching rules.
Be careful.
Negative phrase targeting can exclude more searches than you intended.
For example, blocking a broad phrase such as “historical fiction” could prevent your book from appearing for many highly relevant searches.
Use negative keywords precisely, not emotionally.
One expensive click is not proof that a keyword is bad.
Repeated irrelevant traffic is a much stronger reason to act.
24. When Should You Increase a Bid?
Not because you want more sales.
Not because your book deserves more attention.
And definitely not because you’ve had a disappointing morning.
Increase bids when the evidence suggests that additional visibility could be worthwhile.
For example:
- A keyword repeatedly produces sales.
- Its advertising cost remains within your acceptable range.
- Its conversion rate is encouraging.
- You have enough data to justify further testing.
Suppose a keyword is performing well at €0.20 per click.
You might test €0.23.
Then monitor what happens.
A small increase can sometimes generate additional impressions and sales.
But higher bids may also increase your costs without improving profitability.
Make measured changes.
25. When Should You Lower a Bid?
Consider lowering a bid when:
- Clicks are becoming too expensive.
- Sales are insufficient to justify spending.
- ACOS exceeds your sustainable level.
- The keyword remains relevant but is not profitable at its current cost.
Suppose you’ve spent €8 on a keyword that generated one sale worth €3 in royalties.
That keyword may still have potential, but the current economics aren’t attractive.
A lower bid may make it worth continuing to test.
If the keyword is irrelevant, exclusion may be more appropriate than simply reducing the bid.
26. How Many Clicks Before You Stop a Keyword?
Authors often ask:
“Should I stop a keyword after ten clicks without a sale?”
There is no universal answer.
It depends on your royalty, CPC, conversion expectations and tolerance for risk.
Here’s a practical way to think about it.
Imagine:
- Royalty per sale: €3
- Average CPC: €0.25
- Clicks: 20
- Sales: 0
You’ve spent:
20 × €0.25 = €5
That’s already more than the royalty from one sale.
If you’re advertising a standalone book, you may decide to pause or reduce that keyword.
If you’re advertising Book One of a profitable series, your decision could be different.
The important thing is to establish spending rules before your emotions take over.
27. What Is a Good ACOS for Authors?
This question appears constantly in author communities.
Unfortunately, there’s no single correct percentage.
Your break-even ACOS depends on how much royalty you earn relative to the advertised sales value.
Example
Selling price: €10.
Royalty: €3.
Your approximate break-even ACOS is:
€3 ÷ €10 × 100 = 30%
If you spend €3 to generate €10 in attributed sales, you’ve approximately covered the royalty from that sale.
If your ACOS is 15%, you may be making money.
If it’s 60%, you’re likely losing money on the immediate sale.
However, your actual calculation must account for the format purchased, attribution, royalties, taxes and any additional reader value.
For series authors, the lifetime value of a reader can matter enormously.
For standalone authors, immediate profitability may be much more important.
28. Kindle Unlimited Changes the Calculation
If your ebook is enrolled in KDP Select and available through Kindle Unlimited, some readers may borrow it rather than purchase it.
Eligible page reads can generate royalties.
That creates an additional complication.
Your advertising dashboard and your KDP royalty reports measure different things.
You shouldn’t assume every advertising-driven Kindle Unlimited read will appear as a directly attributed book sale.
To evaluate overall profitability, compare:
- Advertising expenditure
- Attributed advertising sales
- Actual KDP royalties
- Kindle Unlimited page-read royalties
- Organic sales
- Changes in performance over time
Be careful not to claim that advertising caused every increase in organic sales or page reads.
Those relationships can be difficult to prove.
But tracking them can help you understand your wider business.
29. Why Series Authors Have an Advantage
Imagine you’ve written a five-book mystery series.
A reader discovers Book One through an advertisement.
You earn €2.50 from that first purchase.
But the reader enjoys the story and buys the next four books.
Your total royalty from that reader might become €12.50.
Now your advertising economics look very different.
You may be able to spend more to acquire a new reader because your potential revenue extends beyond the first book.
This is called read-through.
However, don’t assume every reader will complete the series.
Calculate your actual read-through using reliable sales data.
A series can justify higher acquisition costs, but only when the numbers support that strategy.
30. The 30-Day Campaign Optimisation Calendar
Here’s a practical schedule you can follow.
Days 1–3Check campaign deliveryImpressions, budget, eligibility
Days 4–7Review early trafficClicks, CPC, relevance
Days 8–14Identify emerging patternsSearch terms, orders, spend
Days 15–21Make measured adjustmentsBids, negative keywords, winning targets
Days 22–30Evaluate the experimentACOS, royalties, conversion, total spend
This schedule is a guide rather than a guarantee that you’ll have enough data after 30 days.
A low-budget campaign may require considerably longer.
Remember that advertising reports and sales attribution can take time to update.
Don’t assume today’s dashboard shows the complete outcome of yesterday’s clicks.
31. My Favourite Campaign Naming System
Once you advertise several books, campaign organisation becomes essential.
Imagine having 35 campaigns with names such as:
Campaign 1
Campaign 2
New Campaign
Book Ads
Better Book Ads
Final Campaign
Final Campaign 2
You can see the problem.
Instead, use a consistent naming system:
BOOK | MARKETPLACE | TARGETING | DATE
Examples:
THE STRAND | UK | AUTO | OCT26
THE STRAND | UK | EXACT | OCT26
IRISH BLOOD AND GILT | US | PRODUCTS | OCT26
RADIANT AT 50 | UK | KEYWORDS | OCT26
This makes it much easier to compare performance and identify campaigns.
32. Five Mistakes That Can Destroy a Small Advertising Budget
Mistake One: Advertising Before Your Book Is Ready
If your cover looks unprofessional or your description doesn’t explain the book, paid traffic may not convert.
Fix the sales page first.
Mistake Two: Targeting Every Genre
Your book may contain romance, history, mystery and family drama.
That doesn’t mean readers searching for all those genres are equally likely to buy it.
Prioritise your strongest reader audience.
Mistake Three: Accepting Every Suggested Bid
Amazon’s suggested bids can be useful.
But they don’t know your personal profit requirements.
Your royalty calculations should guide your decisions.
Mistake Four: Changing Everything at Once
If you simultaneously change keywords, bids, budgets and targeting, how will you know which adjustment helped?
Change one major variable at a time whenever possible.
Mistake Five: Confusing Sales With Profit
A campaign that generates €200 in retail sales isn’t necessarily successful if it costs €150 and your royalties are only €60.
Revenue is exciting.
Profit keeps your publishing business alive.
33. Your First Amazon Advertising Worksheet
Before launching your first campaign, complete this simple worksheet.
Book title: ______________________
Genre: ______________________
Primary marketplace: ______________________
Book format: ______________________
Retail price: ______________________
Actual royalty per sale: ______________________
Maximum affordable advertising cost per sale: ______________________
Starting daily budget: ______________________
Starting CPC bid: ______________________
Five most relevant keywords:
Five comparable books:
Campaign start date: ______________________
First review date: ______________________
Maximum experimental loss I am comfortable accepting: ______________________
That final question matters.
Advertising should be an intentional business investment, not a financial gamble.
34. A Practical Example: Advertising an Irish Historical Novel
Let’s bring everything together.
Imagine you’ve published a historical novel set in twentieth-century Ireland.
Its themes include family separation, motherhood, institutional injustice and the search for identity.
You want to reach readers who enjoy emotionally powerful historical fiction.
Your initial advertising plan might look like this:
Campaign A: Automatic Discovery
Marketplace: Amazon UK
Daily budget: £2
Starting bid: £0.18
Bidding strategy: Dynamic bids — down only
Objective: Discover relevant searches and products.
Campaign B: Manual Keywords
Marketplace: Amazon UK
Daily budget: £3
Initial keywords:
- Irish historical fiction
- Historical fiction about women
- Irish family saga
- Irish social history novels
- Historical fiction Ireland
- Mother and baby home fiction
- Emotional historical novels
- Twentieth century Irish fiction
Starting bids: £0.15–£0.25.
Objective: Identify which searches attract buyers.
Campaign C: Comparable Books
This campaign could be introduced later, once you’ve gathered information from the first two campaigns.
Target books that share relevant historical themes and reader expectations.
Daily budget: £2–£3, funded by reallocating the original budget or increasing your overall spending limit.
Objective: Reach readers browsing similar historical novels.
After several weeks, review the results.
If “Irish family saga” is performing well, consider creating a dedicated exact-match target.
If a particular search repeatedly attracts irrelevant clicks, consider excluding it.
If the campaign isn’t generating enough impressions, examine bids, targeting and listing relevance before increasing spending.
This is how a small advertising experiment becomes a structured marketing strategy.
35. The Most Important Lesson: Don’t Advertise Blindly
Amazon advertising isn’t a magical machine that transforms every book into a bestseller.
It is a tool.
And like any tool, its effectiveness depends on how you use it.
Some books convert beautifully.
Others need a stronger cover, better description, clearer positioning or a different audience.
Some keywords will surprise you.
A phrase you thought would be brilliant may generate no sales.
A tiny, obscure keyword may become your most profitable target.
That’s why I encourage authors to approach advertising with curiosity rather than desperation.
Your first campaign is not an examination you must pass. It is an experiment you can learn from.
Start with a budget you can afford.
Choose relevant keywords.
Keep your campaigns organised.
Measure your results.
Understand your royalties.
Make adjustments based on evidence.
And don’t confuse spending money with making progress.
Final Thoughts: You Don’t Need a Huge Budget. You Need a Plan.
One of the biggest myths in independent publishing is that successful book advertising requires enormous amounts of money.
A large budget can help scale an effective campaign.
But it cannot turn irrelevant targeting into a good strategy.
A carefully managed small campaign can teach you which readers are interested in your work, which keywords generate sales and which comparable books attract the right audience.
Those lessons are valuable even when the initial campaign isn’t profitable.
Because once you understand your readers, you become a better marketer.
And the next time you publish a book, you won’t be starting from zero.
You’ll have something much more useful than guesswork.
You’ll have evidence.
So open your advertising dashboard.
Choose one book.
Set a sensible budget.
Launch a small experiment.
And remember that every successful author-marketer started somewhere.
Even if that somewhere involved staring at the word ACOS and wondering whether it was a new character in a science-fiction novel.
Happy advertising!
