How to Identify Which Amazon Product Target Bids to Change

Read the right performance signals

Start by looking at three data points together: ad spend, orders, and ACoS. A target with high spend and few or no orders is a clear candidate for a lower bid, while a target with steady sales and an ACoS below your goal may need no change. A tool like Amazon Ads Dashboard by Todoza can show these metrics side by side.

• High spend plus low sales usually means the target is eating budget without converting.
• A consistently high ACoS can signal that the bid is too aggressive for the current conversion rate.
• Targets with strong sales and acceptable ACoS should generally be left alone.

Set your own ACoS and ROAS guardrails

Before changing bids, define what underperforming means for your account. A low-price product may tolerate a different ACoS than a high-margin item. Use your target return on ad spend or maximum acceptable ACoS as a filter, then group targets into change, watch, and keep lists.

• Targets above your max ACoS are immediate change candidates.
• Targets near your threshold can go on a short watchlist instead of being edited right away.
• Targets well below your threshold are working and should not be grouped with underperformers.

When this matters: prioritizing before bulk edits

This filtering step matters most when you have many product targets and limited time. By ranking underperformers by wasted spend — spend that did not lead to a sale — you can make bulk bid changes in a controlled way instead of applying broad reductions across the board.

Review the worst offenders first, note the target or search term, and keep a record of why each bid changed. That makes bulk edits easier to reverse if performance shifts.
