Intraday Bidding Rules : Smarter Bids When Buyers Are Ready
Timing Matters in Amazon Advertising
In the fast-paced world of Amazon Advertising, timing can be just as important as targeting. Knowing when your potential buyers are most active—and adjusting your bids accordingly—can make a meaningful difference in campaign performance. That’s where Intraday Bidding Rules come into play.
With Adspert’s automation, sellers can take advantage of Amazon’s hourly data to increase their chances of winning bids during high-conversion periods without overspending during quieter hours.
What Is Intraday Bidding?
Intraday bidding is a feature that allows bid adjustments based on the time of day and day of the week. Amazon provides advertisers with the ability to schedule these adjustments using bid modifiers—percentage increases or decreases added to the base bid for specific time windows.
For example, if Adspert detects that conversion rates are consistently higher on Mondays between 6 PM and 9 PM, it can automatically raise your bids during that timeframe. These adjustments are temporary and strategic, ensuring you stay competitive during high-conversion windows without committing to permanent bid increases.
This means that You don't need to guess when your buyers are most active and bid increases are based on actual performance patterns.
This is based on hourly data we receive from Amazon and customers have insight into this data on Campaign and Ad Group level on the Key Figures page, by clicking on the magnifying glass. To see how to get there and to have more explanation on these hourly data please keep on reading here.

But what exactly does this warning refer to?
If you have stored rules in your Amazon Seller Central, such as for time-based bidding, these will no longer apply, as Adspert deactivates and thus overwrites these rules.
