Amazon ACOS Targets by Intent Tier: Stop Running One Number
Most Amazon accounts run on a single advertising cost of sale target. ACOS is your ad spend divided by the sales those ads produced, written as a percentage, and most accounts pick one number and apply it to every campaign and every keyword. It feels disciplined. It is usually the thing holding the account back.
Here is how to set targets by buyer intent instead, so you spend efficiently where the sale is already yours and invest deliberately where new customers actually come from.
The problem
Why one ACOS target quietly caps your growth
One target applied to every click feels like discipline. The trouble is that not every click is worth the same to you. A shopper typing your brand name is almost certainly going to buy. A shopper typing a broad category phrase might be comparing ten products and may never have heard of you.
Charging both clicks against the same number does one of two things. It either overpays for the easy sale you were always going to win, or it starves the harder sale that actually grows the business. Often it does both at once.
When you set targets by intent, the blended number on your reports stays healthy while the account grows underneath it. That is the whole game.
First principles
What intent actually means in Amazon search
Intent is how close a shopper is to buying your product specifically, read from the words they type. It runs along a spectrum. At one end sits your own brand name. At the other sits a broad, generic phrase that describes a whole category. In between sit competitor names, specific feature phrases, and use case searches.
The closer a search sits to your brand and your exact product, the more likely that click becomes a sale, and the less you should have to pay to win it. Reading intent is not guesswork. It is sitting in your search term report. Group the terms by how specific they are to what you sell, and the tiers fall out on their own.
The tiers
The four intent tiers, from defend to discover
Tier one: branded defense
Your brand name and your own product titles. The highest intent there is. The shopper already wants you, so the job is simply to keep competitors from buying ad space on your name and stealing a sale you had earned. This should be the most efficient spend in the account, run well inside your margin.
Tier two: category exact and competitor
Exact product phrases and competitor brand names. The shopper knows what they want and is choosing between options. Intent is high but the space is competitive, so you tolerate a higher cost than branded while still expecting a clear return on each sale.
Tier three: generic category
Broad category phrases. The shopper has a need but no preference yet. This is where you buy new customers. Intent is in the middle, so a higher cost is acceptable because you are paying to be discovered, not just to close a sale that was already leaning your way.
Tier four: discovery and complementary
Adjacent searches, complementary products, and broad research phrases at the top of the funnel. The lowest intent of the four. This tier carries the most tolerant target, and it is the first place to pull back when budget tightens. It is also the tier that feeds future demand, so cutting it to zero has a cost that does not show up on this week’s report.
Setting the targets
Anchor every tier to your margin, not a habit
The right target for each tier is not a number you copy from somewhere. It comes from your own margin and the job that tier is doing. Start with the product margin after Amazon fees and your landed cost. That is your ceiling. If you do not know it cold, the FBA Fee Estimator will get you there in a couple of minutes.
Branded defense should run well inside that ceiling, because the sale was nearly free to win. Generic and discovery campaigns can run closer to it, and sometimes past it on a first purchase, because you are buying a customer who may reorder for months rather than a single transaction.
The mistake is setting the same target for a sale you were always going to make and a sale that brings a brand new buyer into your catalog. One should be cheap. The other is worth paying up for.

Let total ACOS judge the whole system
Targets by tier can drift. Branded looks remarkable in isolation and tempts you to pour budget into it, even though it mostly harvests sales you would have won anyway. Discovery looks expensive and tempts you to cut it, even though it feeds the organic rank that everything else depends on.
The number that keeps the whole thing honest is total advertising cost of sale, your full ad spend divided by your total sales including organic, not just the sales the ads take credit for. You can pressure test the math with the PPC ROI Estimator. When total ACOS trends down over time while you keep investing in discovery, the system is working. When it stays flat no matter what you do, the spend is circular and something needs to change.
Set one target and you optimize for a tidy report. Set targets by intent and you optimize for the business. The difference shows up slowly, then all at once, in the sales the ads were quietly building the whole time.
