If you’re running ads on Amazon, you’ve probably obsessed over your ACOS (Advertising Cost of Sales). Many sellers believe a lower ACoS always means better performance.
But here’s the truth: ACOS alone can mislead you. If you’re not looking at profitability alongside ACOS, your Amazon PPC strategy is incomplete.
In this guide, we’ll explore how to go beyond ACOS, optimize for true profit, and use AI-powered Amazon ACOS optimization tools to scale smarter.
ACOS (Advertising Cost of Sales) is a key metric that shows how much you spend on ads to generate a dollar in sales.
ACOS Formula:
Ad Spend ÷ Ad Sales × 100
For example:
Many Amazon sellers aim to lower ACoS as much as possible. But doing that without looking at profit margins can actually hurt your bottom line.
ACoS tells you how efficient your ad spend is in terms of revenue—not profit.
Let’s break it down with a clear example.
👉 In this case, the product with the higher ACoS made more profit.
That’s why optimizing for ACoS alone can lead to bad decisions.
If you want to increase your Amazon profits—not just lower your ACoS—track the following in your PPC campaigns:
Know your product margins. If your profit margin is 35%, your break-even ACoS is 35%.
This includes your ad spend vs. total revenue, showing how ads impact your entire sales performance—including organic sales.
Track profit at the product level, after ad costs and Amazon fees.
Focus on keywords that not only bring traffic but actually convert into profitable sales.
If a product leads to high customer lifetime value (LTV), a higher ACoS may still be worth it.
You shut off a campaign because it has a 40% ACoS. But that product has a 25% repeat purchase rate.
Missed opportunity: Long-term profits.
You double down on a campaign with a 15% ACoS. But after costs and returns, your profit per sale is $2.
Result: You’re scaling a low-margin product with little gain.
If you’re managing your ads manually, tracking profit across hundreds of SKUs can be overwhelming. That’s why top sellers use automation.
Bidventor is an AI-powered Amazon PPC optimization tool that automates bidding, increases conversions, and lowers ACoS. By leveraging machine learning, it ensures your ads reach the right audience at the best price—without overspending.
Bidventor identifies a keyword with a 33% ACoS that leads to frequent repeat purchases. Instead of cutting the bid, it maintains visibility to maximize long-term profit.
Here are some actionable tips to help you go beyond ACoS and optimize your Amazon ads for profit:
Use this as your benchmark instead of aiming for arbitrary ACoS numbers.
Keep high ACoS discovery campaigns separate from branded, low-ACoS campaigns. Optimize them differently.
Track how your ads contribute to total revenue growth.
Evaluate long-term profitability from customer cohorts, not just first-click sales.
Let AI manage your bids based on profit signals, not emotional decisions.
Amazon ACoS optimization is important—but only when paired with margin, LTV, and overall profit tracking.
If you’re only chasing a lower ACoS, you might be cutting ads that actually make money.
The top-performing Amazon sellers focus on what matters most: profitable growth. With Bidventor, you get a smarter, automated way to manage your ads—based on real numbers.
