SP vs SB: Which Amazon Ads Type to Choose for a KDP Book
James Whitfield · July 23, 2026 · 6 min read
Sponsored Products (SP) promote individual books inside search results and on product pages; Sponsored Brands (SB) promote your author brand or a group of books with a banner at the top of search. For most KDP authors the answer is simple: start with Sponsored Products, and add Sponsored Brands only once you have more than one book and a clear brand to show.
This guide explains what each ad type does, where it appears, and how to decide which one deserves your budget as a self-publisher.
What each ad type actually does
Sponsored Products put a single book where buyers are already looking: in the search results for a keyword, and in the "Products related to this item" strip on other books' pages. They look almost identical to organic results, which is why they convert well. This is the workhorse of KDP advertising.
Sponsored Brands show a headline banner, usually at the very top of the search page, featuring your logo or author name and several books at once. They are built for brand visibility and catalog promotion, not for pushing one title.
Side by side
| Sponsored Products | Sponsored Brands | |
|---|---|---|
| Promotes | One book at a time | A brand or a group of books |
| Where it shows | In search results and on product pages | Banner at the top of search |
| Best for | Direct sales of a title | Author brand and catalog |
| Minimum catalog | One book | Usually three or more |
| Learning curve | Low | Higher |
| Where to start | Yes, start here | Add later |
Which should a KDP author choose?
If you have one book: Sponsored Products, without hesitation. Sponsored Brands need multiple titles to fill the banner and rarely make sense for a single book.
If you have a series or several books: run Sponsored Products on each title, and add Sponsored Brands to promote the series as a whole and capture readers at the top of the page.
If you are building an author brand: Sponsored Brands help readers recognize your name across books, which pays off over time even when the immediate ACOS looks higher.
Whichever you run, judge it by ACOS against your margin, not by clicks alone.
A sensible starting order
- Launch Sponsored Products on your best book with a tight set of relevant keywords.
- Once it is profitable, expand keywords and add your other titles.
- When you have three or more books, layer in Sponsored Brands for the series.
Running both types across a catalog quickly becomes a lot of manual bid and keyword work, which is the part Essentia is built to automate.
FAQ
Do Sponsored Brands cost more than Sponsored Products? Not per click by default, but they often show a higher ACOS because they target broader, brand-level intent. That is expected; their value is visibility, not only immediate sales.
Can I run both at the same time? Yes, and established authors usually do. Sponsored Products drive direct sales while Sponsored Brands build recognition. Just track them separately so one does not hide the other's performance.
Which converts better for a new author? Sponsored Products, almost always. They put a single relevant book in front of a buyer with clear intent, which is the easiest sale to win when nobody knows your name yet.
