Competitor Keyword
A competitor keyword is a keyword containing a rival brand's name. Bidding on competitor keywords ("conquest") is a deliberate margin trade — high ACOS, lower CVR, higher new-to-brand acquisition rate — and must be funded from margin headroom.
A competitor keyword (also called a conquest keyword) is an Amazon PPC keyword containing a rival brand's name — for example, a stainless-steel-bottle brand bidding on hydroflask 1L or yeti water bottle. Bidding on competitor keywords is a legitimate strategy with specific economics: high ACOS, lower CVR than branded or generic, but a higher proportion of new-to-brand conversions when it does work.
Why this is risky
Three structural problems with competitor keywords:
- CVR is lower. A shopper typing a competitor's brand name usually wants that competitor. Your CVR on
hydroflask 1Lwill typically be 30–60% of your CVR on the equivalent generic1L water bottle. - ACOS is higher. Lower CVR + competitive auction pressure (the competitor often bids defensively on their own brand) = higher CPCs and higher ACOS.
- Trademark risk. Many brands enforce trademark policies through Amazon. Competitor names appearing in your ad creative (Sponsored Brands headlines, A+ content) can trigger takedowns. Competitor names in the keyword target itself are allowed but you should keep the ad copy generic.
When competitor keywords work
The pattern: bid on competitors where you have a clear, communicable advantage the shopper can recognise on the SERP without clicking:
- Price advantage. Your ASP is materially lower than the competitor's, and the price displays on the SERP.
- Rating advantage. Your star rating is materially higher (4.6 vs. their 3.9).
- Feature advantage. Your title and main image communicate a feature theirs lacks (insulation, capacity, certification).
- Prime advantage. You're Prime-eligible, they aren't.
Without one of these visible advantages, the shopper sees your ad, recognises it as "not the brand I searched for," and continues to the competitor's PDP. You paid for the click; the competitor got the conversion.
ACOS targeting for competitor campaigns
Competitor keywords need a Target ACOS that is structurally higher than the rest of the account, funded from margin headroom on better-performing campaigns:
Target ACOS_competitor = Target ACOS_generic × 1.5 to 2.0
If your generic Target ACOS is 25%, competitor Target ACOS lands at 38–50%. Bidding competitor at generic-ACOS targets means competitor campaigns either run dark (no impressions) or destroy margin (over-bidding).
The New-to-Brand justification
The cleanest justification for tolerating high competitor ACOS is New-to-Brand (NTB). Competitor-keyword conversions are almost always NTB by definition — the shopper was looking for a different brand and switched to yours. A 45% ACOS on a competitor keyword that is 80% NTB is genuinely cheaper customer acquisition than a 25% ACOS on a generic keyword that is 30% NTB, because the lifetime value of an NTB customer is materially higher.
Sponsored Brands and Sponsored Display both report NTB; Sponsored Products does not. Run competitor conquest where you can measure NTB whenever possible.
Sponsored Display product targeting as an alternative
Bidding on a competitor's PDP directly via Product Targeting is often more efficient than bidding on their brand name via keyword targeting:
- The ad appears in the competitor's PDP carousel, not in the SERP — the shopper is already comparing alternatives.
- CVR is often higher (the shopper is in the comparison stage, not the brand-loyalty stage).
- Trademark risk is lower (no competitor name in the keyword field).
Most modern competitor strategies lean heavier on Sponsored Display PAT than on Sponsored Products competitor keywords.
Common mistakes
- Bidding competitor at generic ACOS targets. Either burns margin or runs dark. Set a competitor-specific Target ACOS.
- No visible advantage on the SERP. Without a clear reason to switch, the spend is donation to Amazon.
- Competitor brand name in ad creative. Trademark takedown risk. Keep creative generic.
- Mixing competitor keywords with branded or generic in the same campaign. Makes the high-ACOS competitor line item disappear into the blend; you stop being able to evaluate it as its own decision.
