- Launch ACoS is not steady-state ACoS. Expect to spend above your target for the first few weeks because you are buying data and velocity, not just sales.
- Ramp deliberately, do not dump. Start small, widen targets, and raise budgets as data confirms which keywords convert.
- The day-28 checkpoint is where the plan meets reality. By then you have enough sales history to decide what to scale, what to cut, and where to throttle.
- Throttle on trend, not on a single bad day. Pull back when a target shows a clear pattern of spend without conversions across enough clicks to matter.
- Protect margin with structure, not with panic. A tiered campaign build lets you tighten one lever at a time instead of killing your momentum.
Why does launch-phase ACoS run higher than my target?
When you launch a new product on Amazon, your advertising has two jobs. The first is to generate sales. The second, and honestly the more important one in week one, is to generate data. You do not yet know which search terms convert for your listing, which images resonate, or whether your price holds up against the competition. Every click you pay for during launch is buying you an answer to one of those questions.
That is why a healthy launch ACoS is almost always higher than the number you plan to run at once the product is established. You are paying a premium for information and for the sales velocity that pushes your listing up in organic rank. If you try to hit your long-term target ACoS from day one, you will bid too low, win too few placements, and starve the launch of the data it needs. The product stalls, and you end up thinking the product failed when really the budget strategy did.
So set expectations up front. Decide before you turn ads on how much elevated ACoS you are willing to tolerate for how long. Write it down. A launch without a defined tolerance window is just spending with no exit criteria, and that is where margin quietly disappears.
How should I structure launch budgets so I can control them?
The mistake I see most often is one big auto campaign with a large daily budget and no way to see what is working. When something goes wrong, the only lever is to lower the whole budget, which throttles your winners along with your losers. You want structure that lets you tighten one thing at a time.
Here is the ramp we use across the brands we manage. It is deliberately simple because launch is not the time for clever.
- Days 1 to 7: discovery. Run an auto campaign and a broad match campaign with modest daily budgets. The point is to collect search term data, not to spend fast. Keep bids reasonable and let the placements teach you.
- Days 8 to 14: harvest and separate. Pull the search terms that are converting or getting strong click-through out of auto and broad, and move them into their own exact match campaigns. Now your best terms have their own budgets and bids.
- Days 15 to 27: scale the winners. Raise budgets on the exact match campaigns that are converting. Hold or reduce spend on the discovery campaigns that are still just gathering data. Your spend mix should be shifting toward the proven terms.
- Day 28: the checkpoint. Stop and evaluate everything against your plan. More on this below.
This build gives you granular control. If exact match is profitable but auto is bleeding, you cut auto without touching your winners. That is what protects margin during the messy early weeks.
When should I throttle a campaign during launch?
Throttling is not the same as quitting. It means pulling spend back on a target that is not earning it, so the money flows to targets that are. The hard part is knowing when a bad result is signal and when it is just noise.
The rule I hold to: throttle on trend, not on a single day. A keyword that spent without a sale for one day tells you almost nothing. The same keyword with a clear pattern across enough clicks to be meaningful is telling you something real. In practice, wait until a target has accumulated enough clicks that a conversion should have happened by now given your category, then act. Cutting too early is how you kill a keyword that would have converted on click number twelve.
Signs it is time to throttle a specific target:
- It has spent through a fair number of clicks with zero or near-zero conversions.
- Its ACoS is running well above even your elevated launch tolerance and not improving week over week.
- It is a broad or auto placement that keeps matching to search terms unrelated to your product.
Signs it is not time to throttle yet:
- The target converts but at a high ACoS that is trending down as your organic rank climbs.
- Spend is concentrated in your discovery campaigns, which are supposed to cost more per sale.
- You have only a day or two of data and one weak session is skewing the picture.
The nuance is that during launch some unprofitable spend is intentional. You are buying rank. The moment to throttle is when spend stops buying either sales or useful data.

What happens at the day-28 checkpoint?
Day 28 is not magic, but roughly four weeks is when most launches have enough sales history to make real decisions instead of guesses. By this point your discovery campaigns have done their job, your exact match campaigns have a track record, and your organic rank has either moved or it has not. This is the meeting where you decide the next phase.
Work through these questions in order:
- Is my blended ACoS trending toward target? Not there yet, but heading the right direction? Good. Flat or getting worse after four weeks is a warning that the offer or listing, not the budget, is the problem.
- Which exact match campaigns are profitable? Scale those budgets up. These are your foundation for the post-launch phase.
- Which discovery targets never converted? Pause or cut them. You have their data now and you do not need to keep paying for it.
- Did organic rank move? If your ad-driven sales lifted your organic position on core keywords, you can begin to lower bids on those terms and let organic carry more of the load. That is where launch margin comes back.
- What is my new ACoS tolerance for the next 30 days? Tighten it. Launch is over. The elevated number you accepted in week one should not carry into month two.
How does the launch ramp compare to steady-state management?
It helps to see the two phases side by side, because the goals are genuinely different.
| Factor | Launch phase | Steady state |
|---|---|---|
| Primary goal | Velocity and data | Profitable, efficient sales |
| ACoS posture | Elevated, time-boxed | At or near target |
| Budget direction | Ramping up on winners | Stable with tuning |
| Bid strategy | Wider to discover terms | Focused on proven terms |
| Throttle trigger | No sales and no data | ACoS drift above target |
The reason so many launches erode margin is that brands never transition between these two mindsets. They accept high ACoS for month one, then keep accepting it for month four because nobody drew the line. The day-28 checkpoint is that line. It forces the shift from buying rank to protecting profit.
Where does this fit in a full advertising plan?
Launch budgeting is one piece of a larger campaign structure, and the ramp works best when it plugs into a consistent account build across all your products. If you want the broader framework we use for structuring campaigns, allocating budget, and reading the reports that drive these decisions, our Amazon PPC advertising hub pulls the full set of guides together in one place.
Across 300+ brands and 15 years of doing this, the pattern holds. The launches that protect margin are the ones that treated elevated ACoS as a deliberate, temporary investment with a hard checkpoint, not as a permanent condition. Set your tolerance, build the structure to control it, throttle on trend, and hold the day-28 meeting no matter how busy you are. That discipline is what separates a launch that funds itself from one that quietly drains the account.
Frequently Asked Questions
Why is ACoS higher during an Amazon product launch?
Launch advertising buys data and sales velocity as well as sales. You do not yet know which search terms convert, so each click is also paying for an answer. A healthy launch ACoS is almost always above the number you plan to run at later.
How should you structure Amazon PPC campaigns for a launch?
Days 1 to 7, run an auto campaign and a broad match campaign on modest budgets to collect search terms. Days 8 to 14, move the converting terms into their own exact match campaigns. Days 15 to 27, raise budgets on the exact match winners. Day 28, stop and review everything against the plan.
When should you cut spend on a launch campaign?
Throttle on trend, not on a single day. Pull back when a target has had enough clicks that a sale should have happened and has not, or when its ACoS sits well above your launch tolerance and is not improving week over week.
What should you review at day 28 of an Amazon launch?
Whether blended ACoS is trending toward target, which exact match campaigns are profitable, which discovery targets never converted, whether organic rank moved, and what your tighter ACoS tolerance is for the next 30 days.
