What are Sponsored Products?

Sponsored Products are Amazon's cost-per-click ads for individual product listings. You choose the products to advertise, then either pick the keywords and products to target or let Amazon target automatically. A shopper who clicks the ad lands on that product's detail page, and you pay only for the click.

Definition

A Sponsored Products ad promotes one listing, not a brand, and looks much like an organic result with a Sponsored label. Amazon's own description (Sponsored Products, checked 2026-10-03) sets two conditions: the product has to be eligible for the Featured Offer, and the ad only appears while the item is in stock. Lose either and the ad stops serving, whatever the bid.

Sponsored Products is open to professional sellers, vendors, KDP authors and agencies. For a seller, that makes it the only one of the three sponsored ad types that does not require Brand Registry.

How a campaign is built

A campaign carries a daily budget and a bidding strategy. Inside it, ad groups hold the products you advertise and the targets you bid on. Campaigns come in two kinds, automatic and manual, and manual targeting splits again into keywords and products.

The bid on each keyword or target is the most you will pay for a click. The auction settles what you are actually charged, which is usually lower, and the campaign's bidding strategy decides how far Amazon may move the bid at auction time.

Where the ads appear

On Amazon, the ads serve in and around shopping results and on product pages, grouped into placements you can report on and price separately (bid adjustments help, checked 2026-10-03):

• Top of search (first page): the top row of the first page of results.
• Rest of search: the middle and bottom of results, and page two onwards.
• Product pages: detail pages and other non-search placements such as the add-to-cart page.
• Amazon Business placements: the same three, on Amazon Business.

A placement adjustment raises the bid by a percentage whenever the ad is eligible for that placement, up to 900% according to Amazon (rest of search launch note, checked 2026-10-03). It cannot lower a bid, so the base bid has to suit the placement you value least. The placement modifier entry shows how to set them from each placement's own results.

Sponsored Products also run beyond Amazon. Amazon's off-Amazon help page (checked 2026-10-03) says that, in the marketplaces where it is offered, campaigns serve on third-party sites, apps and creator content by default, using the targeting, bid and budget you already set, and that a campaign setting can limit reach to Amazon. Those clicks spend the same budget, the placement adjustments above do not apply to them, and their results appear in the placement report.

The formula behind every bid

An ad type has no formula of its own, but every decision about a Sponsored Products target comes back to the same three lines:

Revenue per click = Conversion rate × Average order value
Break-even ACoS   = Contribution margin ÷ Price
Max CPC           = Revenue per click × Target ACoS

A keyword's ACoS equals its cost per click divided by its revenue per click, so a target ACoS converts directly into the most a click can cost. Take the target from your own margin, not an industry average: break-even ACoS is the ceiling, and the target sits at or below it.

Worked example

Example inputs, not benchmarks:

• Price $40, Amazon fees $12, landed cost $10. Contribution margin is $18, so break-even ACoS is 18 ÷ 40 = 45%.
• One exact match keyword over a 30-day window that ended more than a week ago: 200 clicks and 16 orders of one unit each. Conversion rate is 8% and average order value is $40.
• Realised cost per click: $1.30.

Revenue per click is 0.08 × $40 = $3.20. At a $1.30 cost per click the keyword's ACoS is 1.30 ÷ 3.20 = 40.6%, under break-even. The 16 orders contributed 16 × $18 = $288 before advertising, the clicks cost 200 × $1.30 = $260, and the keyword cleared $28.

Now suppose your target for this keyword is 30%, because it is a core non-brand term you want to earn on rather than break even. The maximum cost per click is 3.20 × 0.30 = $0.96. The keyword is paying 34 cents a click more than the target allows, so the bid comes down. The max CPC calculator runs the same arithmetic on your own inputs.

Using it to make decisions

• Give each campaign one job. Automatic campaigns find converting queries and products. Manual campaigns price the ones you have proven. Moving a converting search term into a manual campaign is keyword harvesting.
• Price from realised cost per click. The bid is a setting. The cost per click is what the auction actually charged.
• Let the attribution window close. For sellers, Amazon credits Sponsored Products sales made within 7 days of the click, booked on the day of the click. Vendors get 14 days (ad campaign attribution, checked 2026-10-03). Judge a bid change on days that have settled.
• Fix bids before budgets. A budget only decides whether a campaign is running. An unprofitable campaign that runs out of budget needs a lower bid, which saves money and keeps it live all day.

Common mistakes

1. Borrowing someone else's good ACoS. A copied target ignores your fees, landed cost and price, so the same ACoS can be profit on one product and loss on another.
2. Reading yesterday as final. Recent days carry full spend and partial sales, so their ACoS is inflated by construction.
3. Negating converting terms. A search term with sales and a poor ACoS has a bid problem, not a relevance problem.
4. Blending brand and non-brand. Searches for your own brand convert differently from cold searches, and one average describes neither.
5. Forgetting off-Amazon clicks. They share the budget and ignore your placement adjustments.

How it relates to the other ad types and metrics

Because the windows differ, a Sponsored Products ACoS and a Sponsored Brands ACoS are not like for like, even on the same keyword. ACoS counts ad-attributed sales only. TACoS divides the same spend by total sales, organic included.

Dayparting and Sponsored Products

Amazon offers schedule bid rules for Sponsored Products, which raise bids by a set percentage in the hours and days you choose, and schedule-based budget rules, which raise a budget on an hour-of-day schedule (bidding rules help and budget rules API guide, both checked 2026-10-03). Both are documented as increases, and Amazon's documentation does not describe a way to schedule a lower Sponsored Products bid for a weak hour. The Amazon dayparting guide covers how to find the hours worth paying for.

How Shurq helps

Shurq's ad manager reads your Sponsored Products campaigns, targets, search terms and placements next to your other ad types. Its optimisation preview proposes keyword and target bids and placement adjustments in one run, priced against your target ACoS, and holds every row for approval before anything reaches Amazon. The harvest flow promotes the Sponsored Products search terms you select into the ad groups you map them to, as keywords or product targets, starting each bid from the term's realised cost per click where it has one. Bulk actions change the bidding strategy, or the off-Amazon reach setting, across many Sponsored Products campaigns at once. Shurq's dayparting writes hourly bid changes in both directions, so a weak hour can be bid down as well as a strong one bid up. The Amazon bid optimisation guide sets out the method.
