Every KDP author who runs Amazon Advertising campaigns is sitting on a keyword intelligence asset they may not be fully using. The Search Terms report from even a modest advertising campaign contains direct, real-world data on exactly which phrases your target readers are searching for and converting on. This data is more reliable than any keyword research tool — because it reflects actual purchasing behaviour from actual readers of your actual book. For the full keyword strategy, see our complete guide to Amazon KDP keyword research.
Why Ads Data Is the Best Keyword Intelligence
Most keyword research tools provide estimates — educated guesses about search volume and competition based on various data sources. Amazon Advertising data is different: it shows you exactly what happened when your book appeared in front of readers who searched for specific phrases.
When your Search Terms report shows that readers who searched “retired teacher cosy mystery village” clicked on your book and purchased it, you have something no research tool can give you: confirmed evidence that this specific phrase attracts readers who convert for your specific book. That is the most valuable keyword intelligence available.
Setting Up the Right Campaign Type
To generate useful keyword data, you need to run at least one automatic targeting Sponsored Products campaign. Automatic targeting campaigns allow Amazon to show your ads to any search it considers relevant to your book’s metadata — which means they surface search terms you would not necessarily have thought to target manually.
A small automatic targeting campaign — even £5–£10 per week — generates meaningful Search Terms data within two to three weeks. The campaign does not need to be profitable on its own to be worthwhile; the keyword intelligence it generates can improve your organic ranking in ways that compound over the long term.
The Search Terms Report
In your Amazon Advertising dashboard:
- Go to Reports → Advertising Reports
- Select Sponsored Products as the report type
- Select Search Term as the report sub-type
- Set a date range of at least 30 days (60–90 days gives more reliable data)
- Download the report as a CSV
The report shows every search query that triggered one of your ad placements, along with impressions, clicks, spend, and orders for each term.
Reading the Data Correctly
The most important columns in the Search Terms report:
| Column | What it tells you |
|---|---|
| Customer Search Term | The exact phrase the reader typed into Amazon’s search bar |
| Impressions | How many times your ad appeared for this search term |
| Clicks | How many times readers clicked through to your product page from this term |
| Orders | How many purchases resulted from clicks on this term |
| Click-Through Rate (CTR) | Clicks ÷ Impressions — how often your cover/title resonated with searchers |
| Conversion Rate | Orders ÷ Clicks — how often page visitors purchased |
Which Terms to Promote to Organic Keywords
Filter your Search Terms report for terms with at least one order. These are terms that have directly generated a sale. Sort them by conversion rate (orders ÷ clicks).
Terms that meet both of these criteria are your strongest organic keyword candidates:
- Multiple orders (not just a single lucky click)
- Conversion rate above 5% (indicating good reader-book match for this search)
Compare these terms against your current seven organic keyword fields. Any high-converting term that is not already covered by your organic keywords should be prioritised for inclusion in your next keyword update. These are not hypothetical phrases — they are confirmed buyers’ search terms for your book.
Which Terms to Add as Negatives
Terms with high impressions and high clicks but zero orders represent wasted ad spend and potential poor relevance signals. Add these as negative keywords in your advertising campaigns to stop paying for clicks that do not convert.
Additionally, reviewing these irrelevant terms reveals something useful about your organic keywords: if a high-impression, zero-order term in your ads report looks similar to one of your backend organic keywords, that organic keyword may also be attracting the wrong readers to your product page. Consider replacing it.
The Keyword Improvement Cycle
The most productive keyword optimisation process combines ads and organic in a continuous loop:
- Launch: Set initial organic keywords based on research; launch automatic targeting ad campaign
- Collect (weeks 4–8): Gather Search Terms report data
- Analyse: Identify high-converting terms not in organic keywords; identify irrelevant terms wasting ad spend
- Update organic keywords: Add the best-converting terms from ads data
- Update ad targeting: Add high-converting terms as manual targets; add irrelevant terms as negatives
- Repeat every 60–90 days
This cycle progressively refines both your organic keyword strategy and your advertising efficiency simultaneously — each informing the other.
What to Do If You’re Not Running Ads
If you are not running Amazon Advertising campaigns, you lose access to the most reliable keyword intelligence available. The alternatives — manual rank checking, autocomplete research, competitor analysis — provide useful but less precise data.
For authors not yet using advertising, even a small, well-structured automatic targeting campaign pays for itself in keyword intelligence value alone. The KDP Rank Fuel by Vappingo Amazon Ads Generator produces a complete, ready-to-launch campaign with all keyword targeting, match types, and bid ranges configured — removing the setup complexity that prevents many authors from starting.
Your advertising and organic keyword strategies work together. The manuscript quality that earns positive reviews from every reader those keywords attract is what makes the entire system compound over time. Manuscript proofreading for self-published authors from Vappingo ensures the book at the centre of your keyword strategy is error-free and review-worthy.
