Amazon Brand Defense Campaigns: Stop Bleeding Sales to Competitors

Search your own brand name on Amazon right now. Count how many products in the first row aren’t yours. On a young brand it’s common to find two or more, and sometimes the very first result is a competitor who paid to sit above you on a search that only happens because someone already knows your name. That’s the leak Amazon brand defense fixes. These are the cheapest sales in your account, the shopper came looking for you, and other sellers are buying them out from under you for a few cents a click. This guide covers the four campaigns we use, what each costs, and how to tell if the spend is earning anything.

What Amazon Brand Defense Actually Means

Amazon brand defense is advertising on the places that already belong to you, so nobody else can rent them. There are two of those places. The first is the search results page when someone types your brand name. The second is your own product detail page, where Amazon sells ad slots under “Products related to this item,” near the reviews, and in carousels further down.

Most sellers assume both of those spots are theirs by default. They aren’t. Amazon runs an auction on both, and anyone selling in your category can bid on your brand name or target your ASIN. If you don’t bid, the slot goes to whoever does.

So a brand defense campaign isn’t about finding new customers. It’s about keeping the ones who already chose you. That makes it different from almost every other campaign in your account, and it’s why it needs its own budget, its own targets, and its own report.

Here’s what a full defense setup covers:

1. Your brand name and its common misspellings in search
2. Your brand name combined with product words (“yourbrand yoga mat”, “yourbrand refill”)
3. Your own product detail pages, so the ad slots on them show your other products instead of a rival’s
4. The top of the search page on branded searches, through a Sponsored Brands banner with your logo

The hijacker part of the keyword gets mixed in here a lot, so it’s worth separating early. A hijacker is a seller who jumps onto your actual listing and sells against you, often with a cheaper or fake version. Brand defense ads don’t remove a hijacker. In fact, Sponsored Products ads only run when your offer holds the featured offer (the Buy Box), so a hijacker who wins it can switch your ads off. We cover the hijacker fix separately further down, because it uses different tools.

Why Brand Defense Matters More Than It Looks

A shopper who types your brand name has done the hard part already. They saw your product somewhere, maybe an earlier order, a friend’s recommendation, a social post, or an off-Amazon ad you paid for, and came back to buy it. In our experience these are the highest-converting searches in any account, and they’re the ones beginners leave open.

The cost of leaving them open is easy to miss because it never shows up as a line item. Nothing in Seller Central says “a competitor took 6 of your branded sales this week.” The sales just don’t happen. You see a quieter week and blame seasonality, the listing, or the price.

This gets worse once a brand starts getting real traffic from outside Amazon. A seller spends money on a social campaign or an influencer, people search the brand name to buy, and a competitor’s ad sits in the first slot. The seller paid to create the demand and the competitor collected part of it. That’s the worst version of the leak, because you’re funding your rival’s ad performance.

There’s a second reason it matters, and it’s on the detail page. When we pick competitor ASINs to target for clients, we do it by walking through the listing as a buyer. We open the competitor’s page, scroll to the sponsored carousel, read their images, title, bullets, and reviews, and ask one question: “if I were half-convinced to buy this, would my ad here pull me away?” We target the pages where the answer is yes, usually ones with weak photos, thin A+ Content, or a bad review sitting near the top.

That’s what your competitors’ smarter PPC managers are doing to you. If your listing has a weak spot, their ad sits right next to it. Defense means filling those slots with your own products first.

A few numbers to keep in mind:

• Branded clicks are usually cheap, because few sellers bid on someone else’s brand aggressively, so a defense campaign often costs a small slice of total ad spend
• Branded searches usually convert well above your non-branded average, which makes the ACOS look great on paper
• That great-looking ACOS is also the trap, which is why defense spend has to be reported on its own (more on this in the mistakes section)

How to Build the Four Brand Defense Campaigns

You don’t need ten campaigns. You need four, each with one job. Build them in this order, because the first one covers most of the leak and needs nothing but a seller account.

1. Sponsored Products, branded keywords, exact match. Add your brand name, the common misspellings, and brand plus product words as exact match keywords. One ad group, all your hero products. This catches people typing your name in search and puts your products in the top sponsored spots instead of a rival’s. It works without Brand Registry.

2. Sponsored Products, product targeting on your own ASINs. This is the detail-page defense. In the ads console, choose Manual targeting, then Product targeting, then “Individual products.” Our course teaches the same setup for attacking competitors with a 5 to 15 ASIN hit list, and the critical setting is the same here: untick “Expanded” and use “Exact,” so Amazon only shows the ad on the pages you named and doesn’t guess at similar products. Paste in your own ASINs, and the ads on your page start showing your other products. If you sell one product, this campaign does less, but bundles, refills, and sizes all count.

3. Sponsored Brands, branded keywords. This puts your logo, a headline, and a few products in the banner at the top of branded search results. It needs Brand Registry. It’s the most visible defense spot and the one competitors most like to grab, because a banner with their logo on your search is the clearest way to steal attention.

4. Sponsored Display, your own ASINs. This covers more ad slots on your detail pages and some placements off them. It also needs Brand Registry for sellers. It’s the last one to build, and on a small account you can skip it until the first three are stable. We compare these two ad types in depth in our guide on Sponsored Brands vs Sponsored Display.

After the four are live, there’s one more step that most people skip. Go into every non-branded campaign you run, including your auto campaigns and broad research campaigns, and add your brand name as a negative phrase keyword. Our course lesson on negative keywords explains why phrase is the right match type here: a negative phrase blocks any search that contains the word, so one entry keeps every “yourbrand + anything” search out of those campaigns. That routes all branded traffic into your defense campaign, where you can see it, bid on it, and measure it on its own.

Do the same in the other direction. If you run product targeting against competitor ASINs, add your own ASINs as negative product targets in those campaigns, so they aren’t quietly spending attack budget on your own pages.

Setting Bids and Budgets Without Overpaying

Branded bids work differently from the rest of your account. On a normal keyword you’re competing with ten or twenty sellers for a shopper who hasn’t decided. On your own brand name, you’re usually competing with one or two sellers who are trying to steal a shopper who already has decided. The value of that click to you is much higher than to them.

Here’s the process we follow when we set up defense for a brand:

1. Start at Amazon’s suggested bid, not above it. Branded auctions are usually thin. Bidding high on day one just raises your own cost per click with nothing to show for it.
2. Check the top-of-search share after 7 days. In the placement report, look at how much of the campaign’s traffic came from top of search. On branded terms you want most of it there. If it’s low, raise the top-of-search placement adjustment before raising the base bid.
3. Watch for a competitor in the first slot. Search your brand name from a logged-out browser a few times a week. If a rival keeps showing above you, raise the bid in small steps, 10% to 15% at a time, until they drop.
4. Give defense its own budget. Never put branded keywords in a campaign that shares a budget with research campaigns. When the shared budget runs out at 2pm, your brand name goes undefended for the rest of the day, which is exactly when evening shoppers come back to buy.
5. Set the budget so it never runs out. Defense campaigns are cheap enough that capping out is a choice, not a necessity. If the campaign hits its daily cap, raise it.

On how much to spend overall, there’s no Amazon rule, so this part is our judgment. For a brand doing modest branded search volume, defense is usually a small slice of total ad spend, because the clicks are cheap and the volume is limited by how many people know your name. If branded spend starts taking a big share of your budget, something’s wrong. Either your branded volume has grown a lot (good news, and worth checking in Brand Analytics), or you’re overbidding in an auction where nobody is fighting you.

Launch timing matters too. Across the launches we’ve run for clients, $50 a day is the floor we use for a new product’s whole launch budget, because below that Amazon doesn’t get enough impressions to rank the listing. In the first 30 days, almost nobody is searching your brand name yet, so a defense campaign will barely spend. That’s fine. Build it at launch so it’s ready, keep the budget small, and let the bulk of the money go into the non-branded keywords that actually build demand. We lay out how budget should split at each spend level in our Amazon PPC playbook by ad spend.

The Brand Defense Mistakes We See Most

Most brand defense problems aren’t about missing campaigns. They’re about bad reporting, or about expecting ads to fix something ads can’t fix. These are the ones we run into on accounts most often.

Letting branded ACOS hide a weak account. This is the big one. Branded searches convert so well that a defense campaign often runs at a very low ACOS. Mix that into your total and your account ACOS looks healthy while your non-branded campaigns, the ones that find new customers, quietly lose money. It’s an easy thing to miss, because the blended number looks fine. Always report branded and non-branded separately. Our rule of thumb for a healthy product is ACOS around 20% with TACOS between 10% and 15%, and you should check that on non-branded spend, not on a blend that includes your easiest sales. Our ACOS vs TACOS guide walks through how to set both targets.

Paying for sales you’d have made anyway. Some branded clicks would have turned into organic sales with no ad at all, because your listing is the first organic result. The defense campaign takes credit for them. That’s not a reason to skip defense, it’s a reason to measure it properly, which we cover in the next section.

Defending a brand nobody searches yet. A new brand with ten branded searches a month doesn’t need four defense campaigns. It needs one small exact-match campaign and a lot of effort on non-branded demand. Building the full stack too early just adds four campaigns to manage with nothing to manage.

Forgetting the negatives. Without your brand name as a negative in research campaigns, branded searches leak into auto and broad campaigns at higher bids. You end up paying more for your own customers and you can’t tell which campaign is doing what.

Expecting ads to beat a price war. We managed a generic massage-tool product for a client for a year, and every tactic we tried gave a lift for a few weeks, then faded. ASIN targeting on competitors with weak listings worked, listing refreshes worked, PPC tuning worked, and none of it lasted. The problem was the product. Five or more sellers were selling the same physical item and the cheapest one kept winning the wallet. Defense ads can’t fix that. If a rival’s ad on your page is winning because they’re $3 cheaper for the same thing, the fix is differentiation, not a higher bid. We’ve also seen price matchers run 40% to 60% ACOS in their first month, because when every product looks the same, nobody’s conversion rate is better than anyone else’s.

Defending a listing with a structural problem. If your rating is sitting under 4.5 stars, competitors will target your page more, because it’s an easy win for them. Defense ads will slow that down, but they won’t stop shoppers from reading your reviews. In one client launch, a kitchen tool in a category where the top sellers all sat below 4.5 stars, the ads looked healthy for months while returns ate the margin underneath. Fix the listing first, then defend it.

Brand Defense vs Hijacker Defense: Two Different Problems

The keyword “hijacker defense Amazon” gets lumped in with brand defense campaigns, but they protect different things with different tools. A brand defense campaign protects your traffic. Hijacker defense protects your listing itself. You usually need both, and confusing them leads people to spend on ads when the real fix is a report to Amazon.

Here’s why the two connect. Sponsored Products ads only serve when your offer is the featured offer. If a hijacker takes the Buy Box on your listing, your ads for that product can stop serving at the worst moment, so defense ads and hijacker defense end up depending on each other.

The steps we’d take with a hijacker:

1. Confirm it. Check the “Other sellers” section on your listing and note the seller name and price.
2. Do a test buy if you suspect counterfeits. You need proof of what they’re shipping before you report it.
3. Report it through Brand Registry. Use Report a Violation with your test-buy evidence. Amazon’s process changes, so read the current requirements in Brand Registry before filing.
4. Look at Transparency for repeat problems. Transparency puts unique codes on each unit so Amazon can check them. It costs money per code and takes setup, so it’s for brands that get hijacked repeatedly, not a first step.

If you haven’t registered your brand yet, that’s the foundation for most of this. Two of the four defense campaigns and every hijacker reporting tool depend on it.

Measuring Whether Defense Is Earning Its Spend

A defense campaign will always look profitable in the ads report. The question is whether it’s protecting sales you’d otherwise lose, or just charging you for sales you’d have made anyway. You can’t answer that from ACOS alone, so here’s how we check.

Check if anyone is actually bidding on you. Search your brand name from a logged-out browser at a few different times of day, on mobile and desktop. Then open your own detail page and look at who’s in the sponsored carousel. If nobody else ever shows up, your defense spend can stay small. If two competitors show up every time, defense is doing real work.

Use Brand Analytics if you’re registered. The Search Query Performance dashboard shows, for searches that led to your brand, how many impressions, clicks, and purchases went to you versus the whole market. If your share of purchases on your own brand name is well below 100%, someone else is taking branded sales, and defense has a job to do.

Run a pause test, carefully. Pause one defense campaign for 7 to 14 days on a single product, keep everything else the same, and compare total sales for that product (ads plus organic) to the 7 to 14 days before. If total sales hardly move, the campaign was mostly buying organic sales. If they drop and a competitor shows up in your branded results, the campaign was earning its spend. Don’t run this during a big sales event or a stock-out, because the comparison won’t mean anything. And don’t run it on all products at once.

Watch the trend in TACOS. If you add defense and your total ad spend as a share of total sales holds steady or falls, defense is pulling its weight. If TACOS climbs while total sales stay flat, you’re overpaying for clicks you’d have won free.

A simple monthly check covers most accounts:

• Branded ACOS and spend, reported on their own
• Non-branded ACOS and spend, reported on their own
• Your share of purchases on your brand name (Brand Analytics)
• Who appears on your branded searches and detail pages, written down
• TACOS for the month compared with last month

Learning This Yourself vs Getting Help

Brand defense is one of the easier PPC jobs to do yourself. The four campaigns take an afternoon to build, the negatives take another hour, and the monthly check takes 30 minutes once you know what to look at. You don’t need software, and you don’t need an agency. You need to understand how the auction works, where ads show, and how to read your own reports.

That’s what our $27 course covers. The PPC section walks through Sponsored Products, product targeting with the Exact filter, negative keywords by match type, Sponsored Brands, and Sponsored Display, step by step in the ads console, as part of 9 modules. It’s the same playbook our team uses on the stores we manage for paying clients today, which together do about $200,000 a month. If you want to set up defense this week and understand why each setting is there, the course is the cheapest way to get there.

The one thing we’d say before you start: get the basics of your main campaigns right first. Defense keeps the customers you’ve already earned. It doesn’t earn new ones. If your non-branded campaigns aren’t working, fix those before spending time polishing defense.

Frequently Asked Questions

What is Amazon brand defense?

Amazon brand defense is advertising on your own brand-name searches and your own product detail pages so competitors can’t buy those ad slots. It usually means a Sponsored Products campaign on branded keywords, Sponsored Products product targeting on your own ASINs, and, with Brand Registry, Sponsored Brands and Sponsored Display on the same targets.

Do I need brand defense if I rank first organically for my brand name?

Usually, yes. Ranking first organically doesn’t stop competitors buying the sponsored slots above and around you, and those slots often get the first click. Check your branded searches and detail page a few times. If no competitor ever shows up, keep defense small. If they do, it’s protecting real sales.

Can competitors legally bid on my brand name on Amazon?

Amazon generally lets sellers bid on other brands’ names and target other sellers’ ASINs, and it runs normal auctions on them. That’s why defense campaigns exist. If someone is using your trademark in their listing copy or selling counterfeits, that’s a different problem, and you’d report it through Brand Registry.

How much should I spend on brand defense campaigns?

There’s no fixed rule. For most young brands, defense is a small share of total ad spend because branded volume is limited by how many people know your name. Give it its own budget so it never runs out, start at Amazon’s suggested bid, and only raise bids when a competitor keeps appearing above you.

Do brand defense campaigns stop hijackers?

No. Defense ads protect ad slots, not the Buy Box on your listing. A hijacker who wins the Buy Box can stop your Sponsored Products ads from serving for that product. Hijackers need Brand Registry tools, test buys, and Amazon’s Report a Violation, with Transparency codes for repeat cases.

Does brand defense work without Brand Registry?

Partly. You can run Sponsored Products on branded keywords and target your own ASINs without it. Sponsored Brands, Sponsored Display for sellers, Brand Analytics, and the hijacker reporting tools all need Brand Registry, so registering is worth doing before the brand gets real search volume.

The Bottom Line

Amazon brand defense is the cheapest protection in your ad account. A shopper who types your brand name already chose you, and if you don’t bid on that search or on your own product page, a competitor will take the slot and some of the sale with it. You don’t need much to fix it: an exact-match branded campaign, product targeting on your own ASINs with the Exact filter, Sponsored Brands and Sponsored Display once you’re brand registered, and your brand name as a negative everywhere else.

The part that takes discipline is reporting. Keep branded and non-branded numbers apart, check who’s actually bidding against you, and test whether the spend is protecting sales or just buying ones you’d have made anyway. And remember what defense can’t do. It won’t remove a hijacker, it won’t save a generic product from a price war, and it won’t fix a listing under 4.5 stars. Get those right, then defend what you’ve built. The free guide below covers the niches to avoid before you build anything at all.
