Q: Is a low ACOS always good?
The short answer is, No.
Many Amazon sellers become obsessed with lowering ACOS and treat it as the only metric that matters.
But a low ACOS doesn't automatically mean your PPC is performing well.
I've seen accounts where sellers aggressively reduce bids, cut budgets, and pause keywords just to achieve a lower ACOS.
The result?
š Less visibility
š Fewer clicks
š Lower sales volume
š Reduced keyword rankings
š Slower account growth
Yes, the ACOS looks better on numbers.
But the business is actually growing slower.
The goal of Amazon PPC isn't to get the lowest ACOS possible.
The goal is to generate profitable sales while maintaining visibility and creating opportunities for growth.
That's why I don't optimize campaigns based on ACOS alone.
I look at the other factors as well:
ā Profitability
ā Sales Volume
ā Conversion Rate
ā Organic Ranking Growth
ā Overall Advertising Performance
A healthy PPC strategy balances efficiency and growth.
Because sometimes a slightly higher ACOS can lead to significantly more sales, stronger rankings, and better long-term profitability.
Don't chase low ACOS.
Focus on profitable growth. š
