In the Amazon Ads dashboard, you can track ACoS trends pretty easily using just the built-in reports and a little filtering, no third-party tools needed. Here’s the simplest way to do it:
1. Use the Campaign Manager view
Go to Advertising Console → Campaign Manager.
Add the ACoS column (if it’s not already visible).
Adjust the date range (e.g., last 7, 30, 60 days) to see short-term and long-term patterns.
Use the “Compare” toggle in the date picker to compare the current period with a previous one.
2. Check the Advertising Reports section
Navigate to Reports → Create Report → Sponsored Products / Sponsored Brands.
Select the Campaign report or Search term report.
Set a daily or weekly granularity—this lets you see ACoS changes over time.
Download the CSV and open in Excel/Google Sheets for a quick trend chart.
3. Use the “Custom Reports” feature
Create a saved report that includes ACoS, Spend, Sales.
This way, you can refresh it with one click and always have a current snapshot.
4. Optional — Visual Trend Spotting in Dashboard
In the Campaign Manager, click on a campaign name → switch to the Performance over time chart.
Choose “ACoS” from the dropdown to see how it’s moving daily.
