Amazon sellers focus on one goal:
- Lower ACoS
At first glance, this makes sense. A lower Advertising Cost of Sale (ACoS) means you’re spending less on ads relative to your sales.
But here’s the reality:
- A low ACoS doesn’t always mean better performance.
In fact, focusing too much on lowering ACoS can limit your growth.
The Problem with Chasing Low ACoS
A very low ACoS often means one thing:
- You’re not spending enough
- You’re not maximizing visibility
- You’re missing potential sales
In many cases, sellers reduce bids or budgets to improve ACoS, but this also reduces:
- Impressions
- Clicks
- Total revenue
So while efficiency improves, overall growth slows down.
ACoS Should Be Measured with Sales
ACoS alone doesn’t tell the full story.
What really matters is:
ACoS + Sales Performance
For example:
- Campaign A → 15% ACoS, low sales
- Campaign B → 30% ACoS, high sales
Which one is better?
In many cases, Campaign B is generating:
- More revenue
- More market share
- More organic growth
This is why strong Amazon campaign management focuses on profit and scale, not just efficiency.
The Role of Break-Even ACoS
Your break-even ACoS is based on your profit margin.
If your margin is 30%:
- 20% ACoS → Profitable
- 30% ACoS → Break-even
- 35% ACoS → Strategic (if driving growth)
Staying below break-even is important, but staying too low may mean you’re underutilizing your campaigns.
Why Break-Even ACoS Can Still Be a Good Strategy
Many sellers think break-even ACoS means there’s no value, but that’s not true in Amazon PPC advertising.
At break-even:
- You’re not losing money
- You’re generating consistent sales
- You’re increasing visibility
More importantly, you’re feeding Amazon’s algorithm with sales data, which can improve:
- Organic ranking
- Keyword relevance
- Total sales
Ads may break even, but your business can still grow.
Why Higher ACoS Can Be Strategic
There are situations where a higher ACoS makes sense:
- Product launches
- Keyword ranking campaigns
- Expanding into competitive markets
- Scaling high-performing keywords
In these cases, ads are not just generating sales, they are building momentum.
The Real Goal: Profitable Growth
Instead of asking:
❌ “How do I lower my ACoS?”
Ask:
✅ “How do I increase sales while staying profitable?”
This shift changes your strategy:
- You scale winning keywords
- You invest in visibility
- You grow total revenue
This is how experienced Amazon ads experts approach Amazon PPC advertising.
