A client called me once, genuinely panicked, and said something I have not been able to forget. “Our ads are performing great. We’re losing money though.”
I made him repeat it. Slowly. It sounded like a riddle and I needed to be sure I had heard it right and not, say, misplaced a decimal somewhere in my own head.
He had not misspoken. ACoS healthy. CTR healthy. Every chart in his dashboard is a cheerful, reassuring green. The bank account, meanwhile, was having a completely different conversation. I have started calling this the green light problem. Everything is green. Somehow nothing is fine. It is the business equivalent of a smoke detector that only beeps to tell you it loves the smoke.
Welcome to the Amazon PPC trap. Population, considerably more brands than will ever admit it out loud at a conference, mostly because admitting it requires admitting you have been quietly funding Amazon’s quarterly earnings call.

How it starts
It always starts sensibly. That is the genuinely annoying part. Nobody trips into this one. They tiptoe in, very reasonably, one step at a time.
You launch. You need visibility. PPC is the fastest route there. Sales follow. Lovely, you think. This works.
Then competition shows up, as it always does, uninvited, like a relative during dinner. Your organic ranking dips slightly. Cost per click creeps up. You raise the budget to hold your volume. Fine. Sensible. The kind of decision nobody would question in a meeting.
Then someone undercuts your price, because apparently that is just what Tuesdays are for now. You run a promotion. The promotion brings volume and quietly assassinates your margin in broad daylight. So you raise PPC spend again, this time to make up for the organic ground you just lost.
And then, without any kind of formal announcement, no memo, no email, no gentle warning from Jeff, you are spending three times what you spent eighteen months ago for the same revenue at a fraction of the margin. The trap does not send updates. It just quietly becomes Tuesday. Every Tuesday, forever, unless someone notices.

What the dashboard will not tell you
Amazon’s PPC dashboard is genuinely excellent at telling you what happened. It is suspiciously, almost professionally evasive about why, or whether any of it actually mattered.
A low ACoS feels wonderful right up until you realise most of those clicks are people searching your own brand name, people who were buying from you regardless, ad or no ad, rain or shine. A high CTR feels great until your conversion rate has been quietly sliding for three months while everyone stays distracted by the click number, the way a magician keeps your eyes on the wrong hand. A strong ROAS can sit very comfortably next to a business losing money on every single unit once fees, storage and returns actually enter the chat.
The metric worth watching is not ACoS. It is TACoS. Total ad spend as a share of total revenue, not just the revenue your ads are claiming credit for, the way an overconfident colleague claims credit in a group project. When that number climbs while organic share shrinks, you are not getting more efficient with ads. You are getting dependent on them. There is a difference, and Amazon is thrilled either way, frankly.

What actually fixes it
The instinct is always to optimise the campaign. Sharper targeting, smarter bidding, a negative keyword list longer than your last relationship and considerably easier to maintain. All of this helps, marginally. None of it fixes the actual problem.
The brands that genuinely escape this go back and fix the thing PPC was only ever supposed to amplify. A listing that actually explains the product instead of assuming everyone already gets it. Reviews that are real, the kind people write because they meant it, not because a popup begged them to. Pricing that makes sense for the margin instead of pricing that makes sense for the panic of a Tuesday afternoon. A product that sells itself a little, so the ad’s job becomes easy instead of impossible.
PPC was designed to push something that is already rolling downhill. The moment it becomes the only thing keeping the cart moving uphill, in the rain, on a flat tire, it is doing a job nobody built it to do. And it will let you know that. Expensively. Repeatedly. Politely, even, via your monthly statement.
So what do you actually do
Stop increasing the budget. Genuinely. Just stop, take a breath, maybe step away from the laptop for the length of one cup of tea.
Ask a different question. Not how do I get more traffic. Why is the traffic I already have not converting the way it should. The honest answer almost always lives somewhere in the listing, the price, the reviews, or the product itself. Fix that first. Then let PPC quietly do the much smaller, much easier job it was always built for.
Spending more on a leaking funnel does not fix the leak. It just makes the leak considerably more expensive to maintain, which is a genuinely odd thing to optimise for, and yet here we collectively are, year after year, doing exactly that.
If any part of this sounds a little too familiar, that is more or less a weekly conversation at Ergode. Happy to have it with you too, ideally before the dashboard starts lying to you in such a cheerful shade of green.
