Amazon competitor targeting is the practice of putting your ads in front of shoppers who are considering a rival product, either through product targeting on specific competitor ASINs or through keyword campaigns on competitor brand names. Amazon serves product targeting ads on the targeted product's detail page and on search results where that product ranks near the top. It pays only where your offer visibly beats the listing you target.
In the accounts I audit, the product targeting campaign is the one most often built on hope: the category's biggest sellers, bid like proven keywords, never compared against the listing being advertised. This guide covers how I choose competitor ASINs and keywords, build and price the campaigns, tell conquest that pays from conquest that burns budget, and defend your own brand and listings.
What is competitor targeting on Amazon?
Competitor targeting buys a seat inside a shopper's comparison. Product targeting places your ad on a rival's detail page and in search results where that rival sits near the top; competitor keyword campaigns place it on searches that name a rival's brand. Either way, the shopper already has an alternative in mind, and your ad is the interruption.
Amazon treats this as normal practice: its targeting guide lists conquest, meaning targeting competitors' products, as a campaign strategy. Product targeting in Amazon PPC aims three ways: exact ASIN targets name one product, expanded ASIN targets reach products Amazon considers similar to it, and category targets cover a whole category.
The part I see missed most is the search half. Product targeting ads can also serve in search results where the targeted ASIN ranks near the top, so an ASIN target is partly a claim on that product's keyword footprint: target a rival holding page one on your best terms, and you are bidding into searches you already fight for.
How to find competitor ASINs worth targeting
The best competitor ASINs to target are the ones your ads have already converted on. Start with the ASIN rows in your own search term report, add the products ranking on page one for your best keywords, then keep only the rivals your listing beats in a side-by-side comparison. Popularity alone is not a reason.
Start with the ASINs already converting for you
Your search term report already lists the competitor pages your ads have served on. Detail-page matches from your auto campaign's substitutes and complements groups, and from any expanded product targeting, show up there as ASIN rows instead of typed words. Sort those rows by orders: an ASIN that already converted for you is a proven target, not a guess.
Amazon's Sponsored Products best practices point the same way: pull your best-performing products from the search term report and target them in a manual product targeting campaign. The rows are ten-character codes, most starting with B0. I hold them to my keyword bar: two or more orders, because a single order proves little, plus a look at the listing to confirm it is a real alternative.
Add the page-one shelf for your best keywords
The second source is the competition you already face on proven keywords. Search your top converting exact match terms and note which products hold page one; for brand-registered sellers, Brand Analytics' Top Search Terms view shows the three most-clicked products per term. Treat that shelf as candidates, not targets: the most-clicked product is often the hardest to beat.
The tile test: which rivals you can actually beat
On a rival's detail page, your ad is a small tile: main image, price, star rating, review count. The shopper holds that tile up against the listing they are already reading. I only target a competitor when the advertised product wins on at least one of those signals and loses on none by a margin visible at a glance.
A slightly higher price with a clearly better rating is a fair fight; a lower rating at a higher price is a donation. The sharpest angle sits in a rival's one- to three-star reviews: if the complaint that keeps repeating is one your product fixes, and your main image shows the fix, that competitor deserves real budget.
How to find competitor keywords on Amazon
Competitor keywords are searches that contain a rival's brand or product name. Find them in your own search term report first, since broad, phrase, and auto campaigns already catch them, then measure each brand name as a single word across every search it appears in. Reverse-ASIN tools can widen the list, but your own data decides.
The fastest read is n-gram analysis. The free N-Gram Analyzer splits search terms into single words and short word runs, so a rival's brand name shows as one line with its combined spend and orders. Names that convert are candidates; names that only spend are negatives. Then read intent: brand plus a generic product word often means the shopper is still comparing, while an exact product name usually means the decision is made.
Whatever qualifies gets its own campaign. One rival name bought by three campaigns at once is search term bleed with a brand attached, so give competitor keywords one owner and negate the names in your non-brand keyword campaigns, the separation my campaign structure guide applies to brand terms. Wider research methods are in my keyword research guide.
How to set up ASIN targeting for competitors, step by step
Build conquest as its own campaign, never as targets mixed into keyword campaigns. Pull the ASINs your data already proves, qualify each one against your listing, bid each target individually below your fair price per click, fence the data with negatives, and judge every target on a fixed spend threshold before you cut or scale it.
- Pull 60 days of search term data. Download the bulk file with Sponsored Products search term data included and filter the customer search term column to ASIN rows.
- Shortlist from evidence, then from the shelf. Keep ASINs with two or more orders, then add page-one rivals on your best exact match keywords.
- Run the tile test. Compare price, rating, review count, and main image, skim the critical reviews, and drop any rival your listing loses to at a glance.
- Build a dedicated product targeting campaign. One per advertised product, exact ASIN targets only, its own budget. The free Campaign Builder writes product targeting by exact or expanded ASIN into an upload-ready bulk file.
- Price each ASIN on its own. Start below your fair bid (target ACOS times revenue per click), since conquest traffic is unproven, and let each target's own data move it from there.
- Fence the data with negatives. Negate your own ASINs in auto and expanded targeting, competitor names in non-brand keyword campaigns, and each graduated ASIN as a negative product target in the campaign that found it.
- Judge on spend, then cut or scale. Pause targets that spend twice your target cost per order with zero orders, reprice the converters, and rerun the tile test monthly, since rivals change prices and collect reviews.
What conquest targets cost on real numbers
A conquest target that converts can still lose money if it is bid like a keyword. On my sample account, a click earns $2.43 in ad sales, so a 30% target ACOS makes $0.73 a fair bid. A competitor ASIN converting at half the account's rate earns half per click, so its fair bid is about $0.36, not $0.79.
The account is the one graded in my benchmarks guide: 45,672 clicks and 4,140 orders on $36,303 of spend, returning $111,058 in ad sales, or 9.1% conversion, $0.79 per click, and a 32.7% ACOS. The half-rate competitor is a hypothetical for the arithmetic, not a measured result.
| Metric | Account average | Competitor ASIN at half the rate |
|---|---|---|
| Conversion rate | 9.1% | About 4.5% |
| Clicks per order | About 11 | About 22 |
| Ad sales per click | $2.43 | $1.22 |
| ACOS at the account's $0.79 CPC | 32.7% | About 65% |
| Fair bid at a 30% target ACOS | $0.73 | $0.36 |
| Ad cost per order at the fair bid | $8.05 | $8.05 |
Row four is a conquest target bid like a keyword: the $0.79 click that runs the account at 32.7% ACOS runs the weaker target at roughly double. Row six is the fix: at a fair bid, cost per order always equals target ACOS times average order value, about $8.05 here. Conversion rate decides how many orders a target delivers; the bid decides whether they make money.
It is also why I judge conquest targets on spend, not clicks. At a fair bid, twice the target cost per order (about $16 here) buys roughly two expected orders, so a target that crosses it with nothing has had its fair trial. The pricing method is in my guide on how to set Amazon PPC bids from your own numbers.
When conquesting pays and when it only burns budget
Conquesting pays when the shopper's comparison favors you: a lower price, a stronger rating, deeper reviews, or a fix for the rival's most common complaint. It burns budget when you target a rival your listing loses to at a glance, when you bid conquest clicks like keyword clicks, or when you conquest before your own keywords convert.
| Tactic | When it works | When it wastes money |
|---|---|---|
| Exact competitor ASINs | The ASIN already converted for you, and your tile wins on price, rating, or reviews | The rival has more reviews, a better rating, and a similar price |
| Expanded ASINs | Short discovery runs, with converters graduated to exact targets | Left running unwatched, drifting onto products that are not real alternatives |
| Category targets | Narrowed to the brands and price band you actually beat | Unrefined, buying slots beside every rival in the category |
| Competitor brand keywords | Brand plus a generic product word, while shoppers are still comparing | Exact product-name searches from shoppers who have already decided |
| Complement ASINs | A true accessory, refill, or companion to the product on the page | A loose adjacency nobody buys together |
| Your own ASINs | A catalog with complements or upgrades to show on your best sellers' pages | Nothing in your catalog adds anything to the page |
| Branded keyword defense | Rivals are actively bidding on your brand name | Nobody contests your brand, and a taper test shows the sales hold without the ads |
On my benchmark table, the Market Share phase is the one built for this: taking shelf from rivals is its job, and it tolerates account ACOS under 30% where Profitability demands under 15%. A launch is usually the wrong moment, because a listing with few reviews fails the tile test against most established rivals; my product launch guide covers what to fund first. Already running conquest? The free Wasted Spend Finder ranks zero-order spend from one bulk file, and a product targeting campaign near the top has answered the question.
How to defend your brand and listings from competitor ads
Defense runs on the same two tracks as attack. Protect branded searches with a separate exact-match brand campaign, and protect your detail pages by targeting your own ASINs so sibling products fill ad slots a rival would otherwise buy. Then fix the tile: a competitor conquesting you only wins when their tile beats yours.
Start by checking whether you are a target: search your brand name and your top product's name, then read the sponsored rows on your own detail page. Branded search gets a brand defense campaign at exact match with its own budget, walled off as my campaign structure guide describes. Keep branded ad sales at or under 25% of the total while defending market share, and no more than 15% after that.
For listings, Amazon's best practices guide suggests running ads on your own product pages, with higher bids, to keep your range visible there. With a catalog, a complement or upgrade in the ad slot on your best seller's page is a cross-sell you control and one less slot for a rival. Brand-registered sellers can add Sponsored Display to defend those pages too.
Frequently asked questions
Does Amazon allow you to target competitor products?
Yes. Amazon's own Sponsored Products targeting guide lists conquest, meaning targeting competitors' products, as a campaign strategy, and product targeting lets you aim ads at specific products, categories, or brands. Allowed is not the same as profitable: target the rivals your listing beats on price, rating, or reviews, and price each ASIN from its own conversion rate.
Where do Amazon product targeting ads appear?
On the targeted product's detail page, and in search results where that product ranks among the top listings, according to Amazon's targeting guide. The second placement is easy to miss: a strong competitor ASIN carries its keyword rankings with it. In your search term report, detail-page clicks show up as ASIN rows rather than typed search terms.
How much should I bid on a competitor ASIN?
Less than on your proven keywords, at first. A fair bid is target ACOS times revenue per click, and shoppers on a rival's page usually convert less often, so each click earns less. On my sample account the fair bid is $0.73 at the 9.1% account conversion rate, but about $0.36 for a target converting at half that.
What is the difference between ASIN targeting and category targeting?
ASIN targeting names individual products, so your ad competes on those detail pages and the searches where they rank. Category targeting names a whole category and lets Amazon place you beside any product in it, including rivals you lose to. Narrow it with refinements such as brand or price range, or run it as discovery and graduate converting ASINs into exact targets.
How do I stop competitors from advertising on my Amazon listing?
You cannot block them; any advertiser can aim product targeting at your ASIN. You can compete for the space instead. Target your own ASINs in a separate campaign so your other products take ad slots on your pages, cover branded searches with a brand defense campaign, and strengthen what their tile is compared against: price, rating, reviews, and main image.
