If you have run any ads on Amazon, you have run Sponsored Products. It is the ad type with the lowest barrier to entry, the most placements, and in most accounts the largest share of spend. It is also the ad type that most sellers never fully understand, because it works well enough on defaults that the details seem optional.
They are not. The difference between a Sponsored Products account that runs at 40 percent ACoS and one that runs at 20 percent is almost never the product. It is structure, bidding, and how the account is maintained after launch. This guide covers all three.
What Sponsored Products is
Sponsored Products ads promote a single listing. They appear in search results, on product detail pages, and in a handful of other placements across Amazon, and they look like organic results with a small "Sponsored" label. When a shopper clicks, they go straight to your product page.
You pay per click, in an auction. The amount you bid, combined with how likely Amazon thinks the shopper is to buy, determines whether your ad shows and where. Relevance matters as much as the bid: a high bid on a keyword that does not match your product will cost you clicks that do not convert, and Amazon will gradually show it less.
There is no creative to produce. The ad is your listing: its main image, title, price, rating, and Prime badge. This is why Sponsored Products rewards good listings so directly. The ad can only be as good as the product page it points at. For a side-by-side of all three sponsored ad types, see this overview of Amazon sponsored ad types.
Targeting: automatic and manual
Every Sponsored Products campaign targets in one of two ways.
Automatic targeting lets Amazon decide which searches and product pages your ad shows on, based on your listing content. It is easy to set up, and it is the best source of keyword discovery you have, because the search term report shows you what shoppers actually typed before buying. Automatic campaigns have four match groups: close match, loose match, substitutes, and complements. You can bid on each separately.
Manual targeting means you choose. Keyword targeting lets you bid on specific search terms in broad, phrase, or exact match. Product targeting lets you bid on specific ASINs, categories, or brands, so your ad appears on competitor product pages or alongside related products.
The standard structure is to run both. Automatic campaigns find the terms; manual campaigns scale the ones that work. The search term report from the auto campaign feeds the keyword list in the manual campaign, and the terms that convert get moved to exact match with their own bids. The ones that do not convert become negative keywords in both. This comparison of automatic and manual campaigns goes deeper on when each one earns its place.
Campaign structure that holds up
The most common structural mistake is putting too much in one campaign. One campaign with every product and every keyword means the budget is shared across things that perform very differently, and the campaign-level reporting hides which ones are actually working.
A structure that holds up over time usually looks like this. One campaign per product or tight product group. Within it, separate ad groups for automatic targeting, broad and phrase match keywords, and exact match keywords. Exact match campaigns for your best keywords often get their own campaign entirely, so their budget is protected from the discovery work happening elsewhere.
The point of this separation is control. When a product has its own campaign, you can set its budget, read its ACoS, and schedule it independently. When a keyword has its own exact match line, you can bid precisely on it without broad match siphoning the budget. This guide to campaign structure walks through the full layout.
Bidding: what the options actually do
Amazon offers three bidding strategies at the campaign level, and the names are less descriptive than they sound.
Dynamic bids, down only, lowers your bid when Amazon thinks a click is unlikely to convert. It never raises it. This is the conservative default and the right choice for most campaigns most of the time.
Dynamic bids, up and down, also raises your bid by up to 100 percent for top of search placements and 50 percent elsewhere when Amazon thinks a conversion is likely. This can perform well on proven keywords and can be expensive on unproven ones, because Amazon's confidence in a conversion is not the same as your margin tolerating it.
Fixed bids do exactly what you set. No adjustment either way. Useful when you want full control or are testing something and need the bid to hold still.
On top of the strategy, you can set placement modifiers that raise your bid by a percentage for top of search or product page placements. A keyword that converts far better at the top of search than in the rest of the results can justify a large modifier there. One that converts about the same everywhere does not. This bid strategy guide covers the trade-offs in more detail.
Placements and why they matter
Sponsored Products ads show in three broad places: top of search, the rest of search, and product pages. They perform differently, and the difference is usually large.
Top of search converts best and costs most. Shoppers at the top of results have intent and have not yet been distracted by alternatives. Rest of search is cheaper, lower converting, and large in volume. Product pages reach shoppers who are already looking at something, often a competitor, and conversion depends heavily on how your product compares to the one they are on.
The placement report in the console shows spend, clicks, and sales by placement for every campaign. Read it monthly. It is the fastest way to find a campaign that is burning budget on product pages that never convert, or one that would benefit from a larger top of search modifier.
The metrics to watch
ACoS, advertising cost of sales, is ad spend divided by ad-attributed sales. It is the first number everyone looks at, and it is useful, but it is a campaign-level view. A campaign at 30 percent ACoS might contain keywords at 10 percent and keywords at 80 percent, and the average hides both.
Read ACoS at the keyword and search term level, not just the campaign level. That is where the decisions live. What counts as a good ACoS depends on your margin and your goal for the product, and a launch campaign can justify a number that would be alarming on a mature one.
Beyond ACoS: click-through rate tells you whether the listing is attractive in results. Conversion rate tells you whether the page closes. Impression share on your core keywords tells you whether you are visible at all. Together they tell you whether a problem is at the ad, the listing, or the bid.
Maintaining it after launch
A Sponsored Products campaign is not finished when it goes live. It needs three things on a schedule.
Search term harvesting. Every week or two, pull the search term report from the automatic and broad match campaigns. Terms that converted get added as exact match keywords with their own bids. Terms that spent without converting become negative keywords. Skipping this is the single most common reason ACoS creeps up over time.
Bid review. Keywords that convert well with room in your ACoS target get bids raised. Keywords that are spending over target get bids lowered or paused. This is tedious to do by hand across hundreds of keywords and is the task most often automated with rule-based bid adjustments.
Scheduling. Sponsored Products spend around the clock by default, including hours when your category barely converts. Dayparting pauses or lowers bids during those hours and restores them when shoppers return. For most categories this is the fastest ACoS improvement available that does not require touching a single keyword.
Common mistakes
Running only automatic campaigns. They are a discovery tool, not a strategy. Without manual campaigns to scale what the auto campaign finds, you pay discovery prices forever.
Never adding negatives. Every broad match and automatic campaign accumulates irrelevant search terms. Without negatives, they keep spending.
Setting bids once. Bids that were right at launch are rarely right six months later. Conversion rates change, competitors change, and seasonality changes everything.
Ignoring the listing. If conversion rate is low, more ad spend makes it worse, not better. Fix the page before scaling the ads.
Frequently asked questions
What is the difference between Sponsored Products and Sponsored Brands?
Sponsored Products promote a single listing and appear in search results and on product pages, looking like organic results. Sponsored Brands promote your brand and a set of products with a headline and logo, appearing mostly at the top of search. Sponsored Products is where nearly every seller should start because it requires no brand registry and converts closest to the purchase.
Do I need Brand Registry to run Sponsored Products?
No. Sponsored Products is available to any professional seller with eligible listings in the Buy Box. Brand Registry is required for Sponsored Brands and Sponsored Display, which is one reason Sponsored Products is the default starting point.
How much should I bid on Sponsored Products?
Start with Amazon's suggested bid range as a reference, then let your own conversion data set the number. A keyword that converts at 10 percent can sustain a much higher bid than one converting at 3 percent. Set bids by target ACoS and observed conversion rate rather than by what the auction suggests.
