Frequently Asked Questions

How do I calculate optimal Amazon PPC bids?

Optimal bid = (Target ACoS × Avg Order Value × Conversion Rate). For example: 30% ACoS × $30 × 10% = $0.90 max bid. Our calculator factors in your profit margin for sustainable bidding.

What is a good ACoS for Amazon PPC?

Good ACoS depends on your profit margin. If your margin is 30%, an ACoS under 30% is profitable. Break-even ACoS = Profit Margin. Most sellers target 15-25% ACoS.

Should I bid higher or lower on Amazon PPC?

Start with competitive bids to gather data, then optimize. Bid higher on converting keywords and lower on exploratory ones. Our calculator helps find the sweet spot based on your margins.

How does conversion rate affect PPC bids?

Higher conversion rates allow higher bids while maintaining profitability. A 20% conversion rate product can bid 2x more than a 10% conversion product at the same ACoS target.
