Frequently Asked Questions

How is the maximum CPC bid calculated?

Max CPC = Selling Price × (Target ACoS ÷ 100) × (Conversion Rate ÷ 100). Example: $30 price × 25% ACoS × 12% CVR = $0.90 max bid.

What conversion rate should I use?

If you don't have campaign data yet, start with 10% as a conservative estimate. Once you have Seller Central data, use your actual listing conversion rate for accurate results.

Should I always bid at the maximum CPC?

No — the max CPC is the ceiling for profitability. Start at 60–70% of the maximum to gather data, then adjust up or down based on actual ACoS and impression share.

What is a good target ACoS for a new product launch?

New products often run at break-even or negative ACoS to build sales velocity and organic rank. A 'launch ACoS' of 50–80% for the first 2–4 weeks is common before pulling back to a profitable target.
