Every time we onboard a new brand, the first thing we do is a full account audit — ads, listings, catalog, inventory, the works. We’ve done hundreds of these now, and the uncomfortable truth is that the mistakes rarely surprise us anymore. The same seven show up in almost every account, whether the brand was self-managed or paying another agency $5K a month.
These aren’t exotic problems. They’re boring, expensive, and fixable in weeks. And because they’re boring, nobody looks at them — which is exactly why they cost brands six figures a year without anyone noticing.
Here’s the audit, in the order of how much money we typically find lying on the floor.
1. Branded search defended with a sledgehammer (or not at all)
The first place we look is branded campaigns, because that’s where the most money gets wasted in both directions.
The over-spenders are bidding aggressively on their own brand name with no need to. If you own your category and no competitors are conquesting you, you don’t need to pay $1.40 a click to appear above your own organic listing. We routinely find brands spending 8-12% of their ad budget defending branded terms they’d win organically for free. The fix isn’t killing branded — it’s bidding it down to a defensive floor and watching whether organic holds. It almost always does.
The under-defenders are the opposite: a competitor is parked on their brand name, stealing high-intent buyers who were specifically looking for them, and nobody noticed. That’s the most expensive click on Amazon to lose, because the shopper already decided to buy your product.
Branded is a scalpel. Most accounts use it like a hammer or leave it in the drawer.
2. 25-35% of ad spend going to search terms that never convert
This is the single biggest pile of wasted money in most accounts, and it accumulates silently.
When we pull 90 days of search-term reports, we consistently find a quarter to a third of ad spend going to terms with zero sales or an ACOS triple the account target. Auto and broad campaigns harvest junk traffic — irrelevant queries, wrong-intent searches, competitor model numbers that don’t fit — and without a disciplined negation routine, the spend just compounds.
The reason it hides: blended ACOS looks fine. Your winners subsidize your losers, the account average stays acceptable, and nobody drills into the term level. We did, on a recent takeover, and found roughly 28% of spend producing nothing. Reallocating it (not cutting it) into the converting terms lifted attributed revenue without raising the budget a dollar.
If you do one thing from this list, run a search-term audit with a negation pass. It pays for itself in a week.
3. The hero image nobody has ever tested
We’re a full-service agency with a creative director who’s reviewed 50,000+ listings, so we look hard here — and the pattern is brutal.
The main image is the highest-leverage pixel on the entire listing. It decides click-through in the search grid before anyone reads a word. And in account after account, it’s the original image the brand shot at launch and never touched — usually a pretty, designer-approved shot that was never A/B tested against a clearer alternative.
The mistakes are predictable: the product too small in the frame, low contrast against the white background, packaging shown instead of the product, a lifestyle shot where the product is unidentifiable at thumbnail size. Each one quietly suppresses CTR, which means you’re paying more per click and losing organic rank, because click-through is a ranking input.
A hero that goes from unclear to clear routinely moves CTR 10-18%. On a SKU spending real ad money, that’s a five-to-six-figure swing — from one image.
4. A+ content designed on a desktop for an audience on phones
Over 70% of Amazon traffic is mobile, and most A+ content we audit was clearly designed and approved on a 27-inch monitor.
The symptoms: text baked into images that’s unreadable on a phone, comparison charts that collapse into mush on mobile, the most important proof buried in module five or six where nobody scrolls, and a brand-story block sitting above the fold doing nothing for conversion. The decision happens in the first one or two screens, and the best content is usually placed where the fewest people reach it.
The fix is unglamorous: front-load the proof, design and approve on a phone, and kill the decorative modules. A+ content isn’t a brand brochure. It’s a conversion sequence, and most of it is built backwards.
5. Campaigns that can’t be optimized because nothing is segmented
When we open the campaign manager and see a handful of giant campaigns mixing branded, non-branded, auto, and competitor terms together, we know the account is uncoachable in its current state.
You cannot optimize what you cannot segment. If branded defense, non-branded harvesting, discovery, and conquest are all dumped into one budget, you can’t bid them by their actual job — and they have completely different ACOS targets. Branded should run at 5-10% ACOS. Conquest might justify 60%+. Blend them and every decision is a compromise that’s wrong for most of the spend.
This isn’t a bidding problem, it’s an architecture problem, and it’s why brands plateau no matter how much they tinker with bids. We rebuild structure first, then optimize — because the structure is what makes optimization possible.
6. The catalog left undefended
This is the one self-managed brands almost never check, and even some agencies skip it because it’s not glamorous.
We look for: variation families that have been broken or merged badly, listings hijacked by unauthorized sellers sitting on the Buy Box, suppressed or “Frequently Returned” badges quietly tanking conversion, duplicate ASINs splitting reviews and rank, and brand registry that’s set up but not actually enforcing anything. Each of these bleeds revenue, and because they live in the catalog rather than the ad console, they’re invisible to anyone who only watches ACOS.
A single hijacker on a $80K/month ASIN’s Buy Box can cost more in a week than a year of the mistakes above. We check the catalog on day one for exactly that reason.
7. Decisions made on revenue instead of contribution margin
The deepest mistake isn’t tactical — it’s the scoreboard. Most brands we take over are optimizing for revenue and top-line ACOS, and have no per-SKU view of what’s actually profitable after Amazon’s full take.
With referral fees, FBA, storage, returns, and the fuel surcharge, Amazon’s effective cut can push toward half of revenue on some SKUs. A brand “growing revenue” while its contribution margin erodes is running faster to stand still. When we rebuild per-unit economics SKU by SKU, we almost always find products that look like winners on the revenue report and lose money after fees — and the right move is to cut, reprice, or stop advertising them, not scale them.
Revenue is the number brands celebrate. Contribution margin is the number that’s actually theirs.
What this audit usually adds up to
Across a typical takeover, these seven add up to 15-30% of ad spend recoverable, a CTR lift from the hero, a CVR lift from mobile-fixed creative, and a margin correction from the SKU-level rebuild. None of it requires a bigger budget. It requires someone actually looking — at the term level, the catalog level, and the per-unit level — instead of watching a blended dashboard that hides all of it.
The reason these mistakes persist isn’t incompetence. It’s that they’re boring, they’re spread across four different systems, and the metrics that would surface them are averaged away. That’s exactly why a fresh, full-account audit finds them every time.
FAQ
How often should I audit my own Amazon account?
At minimum, a full audit quarterly, with a search-term negation pass every two to four weeks. The ad-side leaks accumulate fastest, so those need the tightest cadence.
Can I run this audit myself?
Most of it, yes — pull 90 days of search-term reports, screenshot your hero next to four competitors at thumbnail size, view your A+ on a phone, check your Buy Box ownership, and rebuild one SKU’s per-unit margin with current 2026 fees. The hard part isn’t finding the data; it’s having the discipline to act on the boring fixes.
Why didn’t my current agency catch these?
Sometimes scope (a PPC-only agency never touches catalog or creative), sometimes incentives (a percentage-of-spend model has no reason to cut your wasted spend), and sometimes just the blended-dashboard blind spot. Ask your agency to show you spend at the search-term level and per-SKU contribution margin. The answer tells you a lot.
What’s the fastest win?
The search-term negation pass. It’s the largest recoverable pile in most accounts and it shows up within days.
