Sponsored Products is the most widely used ad format on Amazon, and it's also the one most brands have strong opinions about while simultaneously running it incorrectly. It's not complicated in theory: you pay for clicks, your ads show up in search results and on product pages, and you try to make sure the clicks are worth more than they cost. In practice, the gap between "running Sponsored Products" and "running Sponsored Products well" is where most of the opportunity lives.
This guide covers how Sponsored Products works, how to structure your campaigns, which settings matter, and where most brands quietly lose money without noticing.
How Sponsored Products Works
Sponsored Products ads appear in Amazon search results and on product detail pages. They look nearly identical to organic listings, which is part of why they convert well. When a customer clicks one, they go directly to your product page. You pay per click, not per impression, so you're only spending money when someone chooses to engage.
The price you pay per click is determined by an auction. You set a bid, Amazon runs the auction when a relevant search occurs, and the winner gets the placement. Amazon uses a second-price auction model, so you pay one cent more than the next-highest bidder, not your own maximum. That said, the math gets more complicated when automatic bidding, bid adjustments, and placement multipliers are in play.
Sponsored Products campaigns can be set to automatic targeting, manual targeting, or both. Automatic campaigns let Amazon decide which searches trigger your ads based on your listing content. Manual campaigns give you control over specific keywords or product targets. Most experienced sellers run both: automatic campaigns to find new keywords, manual campaigns to scale what's already working.
Match Types and Why They Matter
In manual keyword campaigns, each keyword has a match type that controls how closely a customer's search needs to match your keyword before your ad is eligible to show. There are three match types, and relying on only one of them is one of the most common structural mistakes in Amazon advertising.
Broad match is the loosest. Your ad can show for searches that contain your keyword in any order, along with synonyms and related terms. Phrase match requires the words to appear in order, but allows other terms before or after. Exact match only triggers your ad when the search is essentially identical to your keyword.
Broad match finds volume. Exact match gives you precision. Phrase match sits in the middle and is often underused. Most brands know this in theory and underdo it in practice, especially on the negative keyword side.
If broad match campaigns are spending on searches with no realistic shot at converting, negative keywords are the fix. Without them, your broad match campaigns quietly spend money on traffic that has no business converting.
Campaign Structure: What Holds Up
There's no single correct way to structure Sponsored Products campaigns, but there are structural mistakes that consistently create problems. The most common one is putting too many ASINs in a single campaign. When you advertise multiple products together and they compete for the same budget, you lose the ability to see which product is driving spend and which is dragging performance.
Budget management is another area where structure matters more than most brands expect. Amazon can spend up to 25% over your daily campaign limit to capture demand spikes. If your budget runs out early in the day, you're missing afternoon and evening traffic. Portfolio budgets, which cap spending across a group of campaigns, give you more control than per-campaign daily limits alone.
One structural decision worth making early is how you handle brand versus non-brand keywords. Brand campaigns, where you're bidding on your own brand name, typically have lower cost-per-click and higher conversion rates. Mixing brand and non-brand keywords in the same campaign makes performance analysis harder than it needs to be. Separate them, even if the brand campaign is small.
Bidding: Automation and Adjustments
Amazon's default bidding option is Dynamic Bids (Down Only), which lowers your bids when the algorithm decides a click is less likely to convert. Two other options exist: Dynamic Bids (Up and Down), which raises your bid by up to 100% on placements Amazon thinks will convert well, and Fixed Bids, which ignore Amazon's adjustments entirely. Most brands default to Down Only and never revisit it.
Placement bid adjustments are separate from match type bids and worth understanding. You can set multipliers for Top of Search placements and Product Page placements independently of your base keyword bids. If top-of-search placement converts well for a specific campaign, a multiplier increases your bid specifically for that placement without affecting your bids elsewhere. Many brands set keyword bids and ignore placement adjustments, which means they're not competing for the placements that tend to perform best.
On automated bidding: Amazon's campaign-level automation has improved, and for sellers managing dozens of campaigns, rule-based bid automation reduces the manual workload significantly. It's worth understanding what the algorithm is optimizing for before handing it control, though. Amazon's algorithm optimizes for conversions, not ACoS, and those aren't always the same goal for every campaign or product stage.

What to Watch in Your Data
The Search Term Report is the most useful report in Sponsored Products and the one most brands pull less often than they should. It shows every customer search that triggered your ads, along with clicks, spend, and sales for each term. The gap between the keywords you're targeting and the searches triggering your ads is where you find both new keyword opportunities and budget leaks worth closing with negatives.
Beyond the Search Term Report, a few metrics tend to separate well-run campaigns from underperforming ones. Impression share on your core keywords tells you whether you're competitive for the terms that matter. Click-through rate at the ad level signals whether your main image and price are working in the context of a search result. Conversion rate on the product page tells you whether the traffic is qualified.
Most brands focus on ROAS and miss these leading indicators until a problem is already visible in the numbers. There's also no universal ROAS target for Sponsored Products, because the right target depends on your margins, your product stage, and whether you're optimizing for profitability or market share. A launch campaign for a new ASIN should have different efficiency expectations than a mature campaign for a top seller.
Common Mistakes Worth Naming
The most common issue we see with brands new to Amazon advertising is running only automatic campaigns. Automatic campaigns are useful for discovery, but Amazon's targeting choices aren't always yours, and the lack of keyword-level control makes optimization difficult. Automatic campaigns should feed manual campaigns, not replace them.
The other reliable mistake is setting up a campaign and not reviewing it for months. Sponsored Products performance drifts. New competitors enter your keywords, your bid competitiveness changes, seasonality shifts your conversion rates, and algorithm updates change how placements are allocated. A campaign that was well-tuned in January is not necessarily well-tuned in July.
Regular review, at minimum monthly and ideally weekly for high-spend campaigns, is the baseline for maintaining performance rather than watching it slowly degrade.
