Most sellers go looking for the one big problem. In reality, a healthy account rarely fails in one dramatic place. It bleeds slowly, in several small ones at once, and none of them are loud enough to notice on their own.
Here are the seven I check first in almost every audit. Individually each looks minor. Together, on a real account doing volume, they can quietly cost you thousands a month.
1. Search terms nobody has looked at
Broad and auto campaigns are useful for discovery, but left unchecked they spend on search terms that never convert. If nobody is mining the search term report and adding negatives, you are paying, week after week, for clicks that were never going to buy. This is usually the single fastest place to recover margin.
2. Suppressed and stranded listings
A listing gets suppressed over a compliance flag or a missing attribute, and it simply stops selling. Inventory goes stranded and can’t be bought at all. Because the account still shows sales elsewhere, these quietly sit there losing revenue until someone actively looks for them.

3. FBA reimbursements you never claimed
Amazon loses and damages units. It’s supposed to reimburse you, but not everything is caught automatically, and there are windows on what you can claim. Over a year, on real volume, the units you’re owed for add up to a meaningful number that most sellers never pursue.
4. Optimising for ACoS instead of profit
ACoS only measures ad spend against ad-attributed sales. It says nothing about your actual margin. Chase a low ACoS blindly and you can starve profitable campaigns; ignore it and you can scale a loss. TACoS, total ad spend against total revenue, tracks far closer to real profitability. If you’re steering by the wrong number, you’re leaking in a direction you can’t see.
5. Listings that rank but don’t convert
Plenty of listings are keyword-optimised enough to get impressions, then fail to turn those impressions into sales because the copy, images, or A+ content don’t do their job. Every non-converting click you paid for is waste, and every organic impression that bounces is rank you’re not earning. Traffic without conversion is just an expensive way to stand still.
6. Catalog and variation errors
Broken variations, duplicate ASINs, and split listings quietly divide your sales and reviews across pages that should be one. It confuses buyers and weakens ranking. These errors are easy to miss because nothing obviously “breaks”, the sales just never fully consolidate where they should.
7. Stockouts that erase your ranking
Run out of stock on a ranked product and you don’t just lose the sales during the gap. You lose momentum, sales velocity drops, and the ranking you spent money to build slides. Getting it back costs more than it did the first time. Inventory planning isn’t just operations, it’s rank protection.
The point
None of these seven is a crisis on its own. That’s exactly why they persist. The job of an audit is to find all of them at once, quantify what each is worth, and fix them in order of profit impact, biggest first. Do that, and the same account produces more margin from cleaner operations, no extra ad spend required.
