Amazon Competitor Conquesting (Offense & Defense)
Every competitor’s product page is a place your ad could appear — and every one of your pages is a place theirs could. Conquesting is playing both sides of that board on purpose.
Competitor conquesting works two ways: offense — targeting rivals’ ASINs and brand terms to win their shoppers — and defense — bidding on your own brand terms and product pages so competitors can’t win yours. Play defense first (it’s cheap and high-ROAS), and go on offense only where you have a real edge like price, reviews, or Prime. Judge conquesting on new-to-brand, not pure ACoS.
01The two sides of conquesting
Conquesting means competing directly for a rival’s shoppers — and it’s a two-way street. On offense, you place ads on competitors’ product pages and bid on their brand terms to capture shoppers considering them. On defense, you protect your own product pages and brand terms so competitors can’t do the same to you. Most sellers think only of offense, but defense is where the easier, cheaper wins are — so we start there in priority even though offense is flashier.
02Offense: targeting competitors
Offense has two main plays. ASIN targeting uses product targeting in Sponsored Products and Sponsored Display to place your ad directly on a competitor’s detail page — putting your product in front of someone already looking at theirs. Brand-keyword targeting bids on competitors’ brand search terms, so when a shopper searches a rival’s brand, your ad appears alongside. Both intercept high-intent shoppers at the exact moment they’re considering the competition — which is powerful, but only under one condition.
03When offense actually works
That condition: you need a genuine advantage the shopper can see at a glance. Conquesting a competitor whose listing has a better price, more reviews, a higher rating, or a clearer benefit just donates clicks — the shopper compares, prefers them, and you’ve paid for the privilege. Offense pays when your listing wins the side-by-side: better price, stronger reviews, Prime badge, or a sharp differentiator. Before targeting a rival, look at both listings honestly and ask which one a fresh shopper would choose. If it’s not yours, don’t conquest there.
04Defense: protecting your turf
Defense is the quieter, more profitable half. Brand defense means bidding on your own brand terms so you own that search result — because if you don’t, a competitor will conquest it and you’ll literally be paying nothing while they pay to poach buyers searching for you. Branded terms are your cheapest, highest-intent traffic (high relevance means low CPC and excellent ROAS). Own-PDP defense targets your own product pages and related ASINs to occupy that ad real estate with your catalog, crowding out competitors trying to conquest your listings. Defense first, always.
05Offense vs defense
| Play | Tactic | Judge on |
|---|---|---|
| Offense — ASIN | SP/SD ads on competitor listings | NTB, CVR, strategic value |
| Offense — brand terms | Bid on competitor brand keywords | NTB (accept higher ACoS) |
| Defense — brand terms | Bid on your own brand keywords | ACoS (should be very low) |
| Defense — own PDP | Target own ASINs to block rivals | Blocked share, cross-sell |
06The economics
Offense and defense have opposite cost profiles, so judge them differently. Offense runs a higher ACoS — you’re the interloper on someone else’s page, so relevance and conversion rate are lower, and you should measure it on new-to-brand and strategic value rather than pure efficiency. Defense runs a low ACoS — branded terms are hyper-relevant, cheap, and convert well, so they should be among your most efficient spend. Holding offense to a defensive ACoS target will make you abandon profitable conquest; holding defense to an offensive one will make you tolerate waste. Match the yardstick to the play.
07The stockout opportunity
The single best time to go on offense is when a competitor runs out of stock. Their listing can’t convert, their organic rank slips, and their shoppers are actively looking for an alternative — which is you, if your ad is on their page or brand terms. Monitoring key competitors for stockouts and ramping conquesting spend the moment one goes out is one of the highest-ROI moves in Amazon advertising. It’s a temporary, low-competition window where your edge is simply being available.
08Playing it clean
One compliance note keeps you out of trouble. Bidding on a competitor’s brand keywords is allowed, but do not use their trademarked brand name in your own ad copy or Sponsored Brands headline — that crosses into trademark infringement. Target the terms, but keep your creative about your product and its advantages. Play offense on the auction, not on their name. That wraps competitor strategy — next, the biggest event on the calendar: Prime Day.
- Conquesting is two-way: offense (target rivals’ ASINs and brand terms) and defense (protect your own).
- Play defense first — branded terms are cheap, high-intent, and high-ROAS; skipping them invites poaching.
- Go on offense only with a real edge — price, reviews, rating, or Prime — or you just donate clicks.
- Judge offense on new-to-brand (accept a higher ACoS); judge defense on a low ACoS.
- Ramp offense when a competitor stocks out; never use a rival’s trademark in your ad copy.
Frequently asked questions
What is competitor conquesting on Amazon?
It’s advertising that competes directly for a rival’s shoppers — placing your ads on their product pages and bidding on their brand terms (offense), while defending your own pages and brand terms so competitors can’t do the same to you (defense). The goal is to win their customers and protect yours.
How do I target competitors on Amazon?
Use product (ASIN) targeting in Sponsored Products and Sponsored Display to place ads on specific competitor listings, and bid on competitor brand keywords in search. Only target competitors where your listing wins a side-by-side comparison on price, reviews, rating, or Prime — otherwise you pay for clicks that convert to them.
Is bidding on competitor brand names allowed?
Bidding on a competitor’s brand keywords is allowed. What’s not allowed is using their trademarked name in your own ad copy or Sponsored Brands headline, which crosses into trademark infringement. Target the terms, but keep your creative focused on your own product and its advantages.
How do I defend my brand on Amazon?
Bid on your own brand terms so you own that search result and competitors can’t conquest it — branded traffic is cheap, high-intent, and high-ROAS. Also target your own product pages and related ASINs to occupy the ad space on your listings, crowding out rivals trying to appear there.
Is conquesting worth it?
Defense almost always is — it’s cheap and protects revenue. Offense is worth it selectively, when you have a genuine advantage and especially when a competitor stocks out. Judge offense on new-to-brand and strategic value rather than ACoS, since as the interloper you’ll naturally run a higher cost of sale.
