How Sponsored Products work
Sponsored Products run on a keyword auction model. A brand specifies keywords it wants to target — the search terms a shopper might use to find its product. For each keyword, the brand sets a bid: the maximum it's willing to pay per click. When a shopper searches a matched term, Amazon's algorithm runs an auction among competing bids, and the winning ads appear in marked placements — typically at the top of search results, interspersed within search results, and on competitor product detail pages.
The brand pays only when the shopper clicks. The actual cost per click is determined by the auction — typically just above the second-highest bid, not the maximum. The ad links directly to the product listing, where conversion depends on the quality of the page: title, images, bullet points, price, reviews, and A+ Content.
Sponsored Products are available to both Vendor Central and Seller Central brands enrolled in Amazon Ads. No minimum spend requirement. No approval process. This accessibility makes it the entry point for virtually every brand advertising on Amazon — and the most competitive placement on the platform.
Targeting: automatic vs manual
Automatic targeting. Amazon's algorithm determines which searches trigger the ad, based on what it reads from the product listing. The brand sets a bid; Amazon finds the matches. Automatic campaigns are useful for discovery — they surface search terms the brand's keyword team hadn't thought to target, reveal competitor ASINs that drive traffic, and generate data for harvest into manual campaigns.
Manual targeting. The brand specifies its own keywords with three match types: exact (triggers only when the search matches precisely), phrase (triggers when the search contains the keyword phrase), and broad (triggers on loosely related searches). Manual campaigns give brands precise control over which queries they're bidding on and at what CPC.
Most sophisticated brands run both simultaneously. Automatic campaigns do the discovery work and generate search term data. Manual campaigns bid precisely on the highest-value, highest-converting terms from that harvest. The two operate as a connected system, not alternatives.
ACoS vs TACoS: measuring what actually matters
ACoS (Advertising Cost of Sale) is the ratio of ad spend to sales directly attributed to ad clicks, expressed as a percentage. Spend €100, generate €500 in attributed sales: ACoS is 20%. Lower ACoS means more efficient advertising. ACoS is the metric Amazon Ads reports by default, and it's the metric most brands optimize against.
The problem: ACoS is incomplete. It only captures sales that the system attributes directly to an ad click. It misses two things that are commercially real. First, the organic sales halo — when advertising drives visibility and rank, organic sales on the same product increase even without a click. Second, cross-product effects — Sponsored Products on a hero SKU drive traffic that converts to other products in the portfolio.
TACoS (Total Advertising Cost of Sale) divides total ad spend by total sales — both ad-attributed and organic — for the same period. A brand that's investing in Sponsored Products to build category rank will see ACoS look expensive in the short term while TACoS is telling a different, more accurate story: organic is growing because the visibility investment is working. TACoS is the right metric for evaluating whether advertising is building the business, not just churning out attributed revenue.
Sponsored Products as a demand signal
The standard use of Sponsored Products: run campaigns, optimize ACoS, report ROAS. The strategic use: read what the campaign data is telling you about the market.
Which keywords drive clicks but not conversions? That's a content or price signal — shoppers are finding the product relevant enough to click, but something on the page is failing them. A conversion gap on a high-click keyword is telling you something about the listing that product managers and content teams should act on.
Which competitor ASINs does your product appear against, and which of those competitive placements convert? That's a positioning signal — it tells you who Amazon thinks you compete with, and whether shoppers agree.
Which search terms are driving your new-to-brand sales? That question requires Amazon Marketing Cloud, not just the standard Ads console — but the answer directly informs your JBP media investment priorities and your content strategy.
Sponsored Products data is not just a cost report. It's a real-time read on category demand. The brands using it that way make better commercial decisions across the board.
The relationship with retail media strategy
Sponsored Products sit within the broader retail media stack. They are the lower-funnel, intent-based component — capturing demand that already exists. Amazon DSP is the upper-funnel, programmatic component — building demand before shoppers search. The two are complementary, not competing: DSP builds the audience that Sponsored Products convert.
Most CPG brands start with Sponsored Products — it's accessible, measurable, and directly attributable. The progression to a full retail media strategy involves adding DSP for upper-funnel reach, and eventually adding AMC to measure how the whole system works together. Each layer adds cost and complexity; each layer also adds insight and margin that a Sponsored Products-only strategy can't deliver.
