How to Find the Best Hours to Increase Amazon Ads Bids
← Back to How to Find the Best Hours for Amazon Ads Bid Increases
Quick answer
Peak Amazon Ads bid hours are identified by reviewing hourly ad report data for repeated periods of high conversions or strong return on ad spend (ROAS). This process compares performance by hour and day of week, flags consistent patterns, and separates them from one-off spikes. The result is a shortlist of times when raising bids is more likely to support profitable sales rather than increase spend without returns.
Before making any bid changes, it helps to pull a report that shows performance by hour rather than by day. This gives you a clearer view of when shoppers in your target market actually convert, so you can raise bids during those windows instead of applying a flat increase across the board.
Start with hourly performance reports
Your first step is to access the Amazon Ads reporting view that lets you break down metrics by hour. Focus on conversions, sales, and ROAS. You may need to combine multiple days of data, because a single day rarely provides enough signal. If you manage several campaigns, a unified dashboard can make this comparison faster by placing hourly trends side by side. Amazon Ads Dashboard by Todoza offers one way to consolidate those metrics without switching between reports.
- Set the report to hourly or download data that includes the hour field.
- Look at several days of recent performance, not just one.
- Compare conversion count, conversion rate, and ROAS by hour.
Look for repeated high-conversion windows
An isolated spike is not a reliable reason to raise bids. Instead, mark the hours that show repeated high conversions or strong ROAS across several days. Those are the periods where higher bids are more likely to work in your favor. Strong ROAS means the returns justify the spend, not just that sales volume is high.
If certain search terms perform well only during specific windows, it is worth reviewing whether those terms waste budget during the rest of the day. Cleaning up underperforming queries can help keep bid increases focused on the hours and searches that actually convert.
When this matters
This matters most when you are scaling ad spend, running promotions, or competing in categories where placement shifts during the day. A bid increase during the wrong hour can raise costs without adding meaningful sales. A targeted increase during a proven conversion window can help you capture demand when shoppers are already ready to buy.
Use the same hourly report check before making any adjustment. If the pattern is not repeatable, keep the bid where it is and continue monitoring.
