Most Amazon sellers think of PPC as a way to capture shoppers searching for their own product. Competitor targeting flips that — it puts your product in front of shoppers actively looking at your rivals, at the exact moment they're deciding whether to buy.
Done right, it's one of the highest-ROI moves in Amazon advertising. Done wrong, it burns budget on irrelevant audiences with nothing to show for it. After managing $25M+ in Amazon revenue, here's how I approach it.
The Two Ways to Target Competitors on Amazon
Amazon gives you two distinct targeting methods for competitor interception — each works differently and serves a different purpose.
ASIN Targeting (Product Pages)
You select specific competitor ASINs and your Sponsored Product or Sponsored Display ad appears directly on their product detail page — in the "Sponsored products related to this item" carousel or the "Compare with similar items" section.
This is bottom-of-funnel targeting. The shopper has already found a competitor, reviewed their listing, and is on the verge of a purchase decision. You're the alternative appearing at exactly the right moment.
Best for: Brands with a clear, demonstrable advantage over the competitor (better price, more reviews, superior feature set, or a bundle that outperforms the single-unit competitor).
Not for: Products with no clear differentiation. If there's no reason to switch, the click is wasted.
Keyword Targeting (Competitor Brand Terms)
Bidding on competitor brand name keywords — "BrandX yoga mat", "CompetitorY supplements" — puts your ad in front of shoppers actively searching for a specific competitor. They know what they want, but they haven't clicked through yet.
This is top-of-funnel interception. You're interrupting the consideration phase and offering an alternative before they commit. It requires a compelling main image and a price point that invites comparison.
Expect: Higher ACoS than branded or category keywords. This is acceptable because the traffic is high-intent and the win — switching a competitor's customer — has long-term value through repeat purchases and reviews.
How to Build Your Competitor Target List
The quality of your competitor target list determines whether this strategy works or wastes money. You want competitors who are:
- Directly substitutable — same use case, same price range, same customer. Targeting a $200 product when yours costs $30 produces irrelevant clicks.
- Vulnerable — products with declining review scores (3.5–4.1 stars), thin image galleries, or outdated listings are easier to displace. Shoppers on those pages are already uncertain.
- High traffic — use Helium 10's "Cerebro" or a similar tool to identify which competitor ASINs rank for the most keywords. Target their top-traffic ASINs first.
Start with 10–20 competitor ASINs in a dedicated campaign. Add more as you identify which ones convert.
5 Tactics That Actually Work
Target Weak Listings, Not Strong Ones
Beginners target the category bestseller. That's a mistake. The bestseller has thousands of reviews, a polished listing, and a customer base that's already loyal. Your ad will get clicks but few conversions — shoppers see your product, then go back and buy the bestseller anyway.
Instead, target ASINs with 3.5–4.2 star ratings, fewer than 200 reviews, or obvious listing weaknesses (poor images, thin bullets, outdated branding). Shoppers on those pages are already doubtful — a better-looking alternative is a compelling switch.
Use Sponsored Display for Retargeting Competitor Shoppers
Sponsored Display with "Views remarketing" lets you retarget shoppers who viewed a competitor's listing but didn't buy. These ads follow shoppers off Amazon — to third-party apps and websites — keeping your product visible during their consideration period.
The CPCs are typically lower than Sponsored Products competitor targeting, and the audience is pre-qualified: they viewed the competitor, didn't buy, and are likely still in the market.
Defend Your Own Listing Simultaneously
If you're targeting competitors, they can target you back. Run a Sponsored Product campaign targeting your own ASINs with a low bid — this fills the "related products" carousel on your listing with your own products instead of competitors'.
It costs almost nothing (you're rarely outbid on your own ASINs) and prevents competitors from intercepting your shoppers at the last moment.
Pair ASIN Targeting With a Price Advantage or Bundle
When you appear on a competitor's product page, the shopper is comparing you side by side. You need a reason to switch. The most reliable triggers:
- Price that's 10–15% lower with similar or better reviews
- A bundle that delivers more value at a similar price point
- Significantly more reviews or a higher star rating
- A feature the competitor visibly lacks (shown in your main image)
Keep Competitor Campaigns Separate and Budgeted Independently
Never mix competitor targeting with keyword or category campaigns. Competitor targeting typically runs at a higher ACoS — which is acceptable — but if it's pooled with your efficiency campaigns, it skews your reporting and makes optimization impossible.
Give competitor campaigns their own budget (I typically allocate 15–20% of total PPC spend to competitor targeting) and evaluate them on a 30-day window, not week by week.
Competitor Targeting Added 22% to Monthly Revenue
A sporting goods brand with strong reviews (4.6 stars, 800+ reviews) was leaving market share on the table — the top two competitors in their subcategory had 3.8 and 4.0 star ratings with obvious listing weaknesses.
We launched ASIN-targeted campaigns against both, plus keyword campaigns on their brand terms. Within 60 days, competitor targeting accounted for 22% of total ad-driven revenue.
The key: we targeted competitors with weak listings where our superior review score and main image made switching an obvious decision. High-traffic ASINs with strong listings were deprioritized — the click cost didn't justify the low conversion rate.
