You give view-only access to your Amazon Ads account. I go through campaigns, bids, placements, search terms, negative keywords and your listing — and write down where your profit is and where your ads lose money.

Since 2023 I have sold over 77,000 copies of my own books on Amazon KDP and run Amazon Ads for my accounts and for clients. For three years my author community has asked the same question: “I get clicks but no sales — why?” The usual answer is “change your cover”. I look at the ad account instead, and I never give advice without numbers.

What is running, what overlaps, what should have been switched off long ago.
Up and down or down only — and what it does to your budget.
Top of search, rest of search, product pages: where the budget goes and what comes back.
The searches you are actually shown for — not the keywords you think you bought.
In every account I find irrelevant searches that quietly eat the budget.
Title, cover, description, price, categories, reviews, series — what stops a click from becoming a sale.
What is left after ad spend, by month and by campaign. And if nothing is left — why.
Where exactly you lose money and in what order to fix it. Not “try this”, but a numbered list of changes for your account: campaign, keyword, was → now.
Half of the losses happen when an author panics and changes everything at once. The audit says what is working and must stay as it is.
Spend, sales, ACOS and profit after ads for the whole life of the book — and why sales dropped, if they did.
If I find nothing worth fixing, you get your money back.
Pages from a real audit of a nonfiction paperback ($24.99, $12 royalty, US). The book, the niche and the keywords are hidden; the numbers are real. Over its lifetime the ads spent $2,494 and made $8,117 in sales — and the audit shows why the profit stopped in May and the 11 changes to bring it back. Click any page to zoom in.

“Dasha, a HUGE THANK YOU for the audit — this is a whole new level! Everything is clear and to the point: every campaign, every keyword, broken down by ACOS and so on. Even my change history was pulled up and analyzed. This is simply incredible work!
And AuthorLens itself really came alive once I connected it to Claude. Yesterday I used an API key from ChatGPT, and the answers were not as convincing — for example, it did not save negatives in the program. Maybe my settings were not fully connected because they are on different email addresses. Now with AuthorLens + Claude it feels like I switched to the latest sports car. It is really interesting to explore my data this way. For beginners it is simply a treasure trove of knowledge! I think the economic effect of the program is much higher than its cost!”
Darya’s reply: “Thank you ❤️ So nice to hear. That’s exactly right.”
Yes. You invite us with the view-only role in Amazon Ads (Account access → Add user → View only). We can see the numbers but cannot change bids, budgets or campaigns. After the audit you remove the user with one click.
Amazon.com, .co.uk, .ca, .de and other Amazon Ads marketplaces. One audit covers one book on one marketplace; each marketplace is analyzed separately.
One audit = one book. If you have a series or several books, email us — we look at the account and suggest where to start.
The audit needs some history to judge keywords. If your ads have run less than 2–3 weeks, we tell you before you pay.
A written document: summary, a numbered fix list (campaign, keyword, was → now), money by month, every campaign and keyword, organic rank, a listing check and dates to review the results. You make the changes yourself.
If I find nothing worth fixing, you get a full refund. Payment is through PayPal, so you are also covered by PayPal buyer protection.
After the audit you can track the same numbers yourself in AuthorLens — analytics for Amazon KDP, 7 days for $1. We use AuthorLens daily and have a business relationship with it.
