Agencies, courses and software all promise better Amazon ads. The right choice depends less on who is best and more on arithmetic: how much you spend on ads each month, how much profit that spend makes, and whether the fee can realistically be earned back.
Prices below are from each provider’s own website, checked 25 September 2026. AcosControl is our product.
What each option costs
| Option | Typical price | What you get |
|---|---|---|
| Amazon PPC agency | About $1,000 a month minimum, plus 8–15% of ad spend | People running your campaigns |
| Author-specialist service | Priced on consultation | Done-for-you ads for established authors |
| Course | Free to $749, once | The skills to do it yourself |
| Software | $50 to $700 a month | Reporting, automation, or both |
| Doing it yourself | Your time | Full control, and all the work |
Two published agency price lists show the pattern. WebFX charges $975 a month up to $5,000 of ad spend, then 10–15% of spend with a minimum. Ad Badger’s managed service is $975 a month plus 8% of spend, with a $2,500 monthly minimum. For authors, Best Page Forward runs a done-for-you service for authors earning over $10,000 a month, priced on consultation.
Courses range from Kindlepreneur’s free Amazon Ads 2.0, through Ricardo Fayet’s Amazon Ads for Authors at $397, to Mark Dawson’s Advertising for Authors bundle at $749, which also covers Facebook, TikTok and BookBub ads.
The arithmetic an agency has to beat
A fee is only worth paying if it produces more profit than it costs. Here is what an eBook earning 68% of its price actually makes from ads at a 60% ACOS:
| Monthly ad spend | Ad sales at 60% ACOS | Royalty (68%) | Profit from ads |
|---|---|---|---|
| $300 | $500 | $340 | $40 |
| $1,000 | $1,667 | $1,133 | $133 |
| $3,000 | $5,000 | $3,400 | $400 |
At $1,000 a month of ad spend, the ads make about $133 of profit. An agency charging $975 would need to lift that profit roughly eightfold just to break even on its own fee. At most indie-author spend levels, the minimum fee is larger than the profit the ads make, and often larger than the ad budget itself.
extra profit it creates > what it costs
Profit, not sales: an agency that doubles ad sales at the same ACOS has also doubled your spend.
When each option makes sense
| Monthly ad spend | Usually the best fit |
|---|---|
| Under $500 | Do it yourself, with a free course and the Amazon Ads console |
| $500 – $3,000 | Do it yourself with software that cuts the weekly routine to minutes |
| $3,000 – $10,000 | Software, or a bid manager if you want bids changed for you |
| Over $10,000, and no time | An author-specialist service or an agency — now the fee is a small share of spend |
These bands are a rule of thumb, not a law. The real test is always the one above: will the fee come back as profit?
If you do hire an agency
- Have they run book ads? KDP has royalties, Kindle Unlimited page reads and series read-through that product sellers never deal with.
- What do they optimise? The answer should be profit against your royalty, not a generic ACOS.
- How is the fee calculated? A percentage of spend rewards spending more. Ask how they decide when to spend less.
- Who owns the account? Campaigns should stay in your Amazon Ads account, with your history, if you part ways.
Doing it yourself, efficiently
Most of the value in book ads comes from a few habits: bidding from your royalty, waiting long enough before judging a keyword, promoting the searches that sell, and negating the ones that never will. None needs an agency. What they need is a weekly hour and a clear view of the numbers.

How much does an Amazon PPC agency cost?
Published price lists put a typical agency at about $1,000 a month minimum, plus 8–15% of ad spend above a threshold. Ad Badger’s managed service, for example, is $975 a month plus 8% of spend with a $2,500 minimum; WebFX starts at $975 a month.
Is an Amazon ads agency worth it for self-published authors?
Only when the fee is a small share of the profit your ads make. At a few hundred or a few thousand dollars of monthly spend, most agency minimums are larger than the ads’ profit. At large spend levels, a specialist can be worth it.
What does an Amazon PPC management service do?
It runs your Amazon ad campaigns for you: keyword research, bids, budgets, negative keywords and reporting, usually against an agreed ACOS or profit target.
Can I manage Amazon ads myself?
Yes, and most authors should, at least until their spend is large. A free course, the Amazon Ads console and a weekly routine cover what matters.
Are Amazon ads courses for authors worth it?
A course is a one-off cost, which makes it the cheapest way to get better. Start with a free one, such as Kindlepreneur’s Amazon Ads 2.0, and pay for more depth only if you need it.
- Typical agencies cost about $1,000 a month minimum plus 8–15% of spend.
- At $1,000 a month of spend and a 60% ACOS, an eBook’s ads make about $133 profit — far less than most agency fees.
- The test for any fee: does it create more profit than it costs?
- Under about $3,000 a month of spend, doing it yourself — with a course, the console and maybe software — usually wins.
- If you hire an agency, make sure it has run book ads and optimises against your royalty.
