Should you run Sponsored Products, Sponsored Brands, or both? This deep comparison shows KDP authors exactly when to use each ad type — and how to combine them for maximum book sales.
Amazon offers KDP authors three primary ad formats, but two dominate: Sponsored Products and Sponsored Brands. Understanding the difference — and knowing when to use each — is the difference between an ad account that bleeds money and one that compounds your book sales month over month.
This guide breaks down both formats with real data from kdp.ad users across fiction, non-fiction, and children's book categories.
Sponsored Products are individual book ads that appear in Amazon search results and on product pages. They look almost identical to organic listings — just a small "Sponsored" label distinguishes them.
How they work: You bid on keywords or let Amazon auto-target. When a shopper searches for a matching term, your book appears in the results. You pay only when someone clicks.
Key strengths:
Key weaknesses:
Sponsored Brands appear as banner ads at the very top of Amazon search results — above all organic listings and Sponsored Products. They feature your author name or series logo, a custom headline, and up to three books.
How they work: You create a brand campaign with a custom headline and select 3 books to feature. When shoppers search for matching keywords, your banner appears at the top of the page.

Key weaknesses:
| Metric | Sponsored Products | Sponsored Brands |
|---|---|---|
| Placement | Search results + product pages | Top of search results (banner) |
| Books per ad | 1 | 3 |
| Custom headline | No | Yes |
| Minimum books required | 1 | 3 |
| Average CPC (fiction) | $0.45–$0.75 | $0.65–$1.20 |
| Average ACOS (kdp.ad users) | 24.5% | 31.2% |
| Best for | Single books, discovery | Series, brand building |
| Targeting options | Auto + Manual | Manual only |
Use Sponsored Products as your primary ad type in these situations:
You have fewer than 3 published books. Sponsored Brands require a minimum of three titles. Sponsored Products are your only option until you hit that threshold.
You're launching a new book. Auto-targeting Sponsored Products are the fastest way to discover which keywords convert for a new title. Run them for 2–4 weeks before adding manual campaigns.
You want the lowest ACOS. Sponsored Products consistently outperform Sponsored Brands on ACOS for most authors. If profitability is the primary goal, lead with Sponsored Products.
You're testing a new genre or niche. The auto-targeting data from Sponsored Products is invaluable for understanding how Amazon categorizes your book.
Use Sponsored Brands as a complement to Sponsored Products in these situations:
You have a series with 3+ books. Showing all three books in a single banner ad dramatically increases the chance that a reader who clicks Book 1 will also see Books 2 and 3. Series authors on kdp.ad see 40–60% higher read-through revenue from Sponsored Brands compared to Sponsored Products alone.
You want top-of-page dominance. Running both Sponsored Products and Sponsored Brands on the same keywords means your books appear twice on the same search results page — once at the top (Brands) and once in the organic-looking results (Products). This dual presence increases click-through rates significantly.
You're building an author brand. If you publish under a recognizable pen name or in a series with a strong brand identity, Sponsored Brands let you reinforce that identity with every impression — even when shoppers don't click.
The highest-performing KDP ad accounts on kdp.ad use both formats together:
This three-campaign structure gives you coverage across the entire search results page, maximizes brand visibility, and keeps ACOS in check by separating discovery from scaling.
