Can You Switch Between Bid Strategies for the Same Campaign?
← Back to Amazon Fixed Bids vs Dynamic Bids: Which Campaigns Need Which Strategy?
Quick answer
Amazon campaign bid strategies can be changed at any time from the campaign settings area. The switch applies to the same campaign without requiring you to recreate it. Fixed bid and dynamic bidding modes each respond differently to auction signals, so the main task after switching is structured monitoring. A short learning period often follows the change, and early results should be read in context rather than treated as final.
The short answer is yes: Amazon does not lock a campaign into one bidding mode. That makes switching a practical way to test whether fixed or dynamic bidding better matches the campaign’s current performance. The main risk is reacting too quickly before the data settles.
Where to change the strategy
Amazon lets you change the bidding approach within an existing campaign’s settings, so you do not have to duplicate the campaign or reset its history. The option sits alongside the campaign’s targeting and budget controls. Because the change is reversible, some advertisers test a new strategy on a lower-volume campaign before applying it more broadly.
What to monitor after the switch
Performance rarely changes instantly. Give the campaign enough time to exit any initial volatility. The most useful signals are usually spend efficiency, click behavior, and conversion consistency rather than a single day’s ACOS. A structured review helps separate normal auction noise from a real strategy mismatch.
- Spend and wasted spend: check whether spend shifts without a matching improvement in orders.
- Click and conversion volume: dynamic bidding may change traffic quality, so compare conversion rates across a consistent window.
- Search term relevance: review terms that receive increased impression share and decide whether they justify the budget.
An analytics view like Amazon Ads Dashboard can consolidate those metrics across accounts and marketplaces.
When switching makes sense
Switching bid strategies is most useful when a campaign has enough data to show a clear pattern, but not so much that a change creates unnecessary risk. If a fixed-bid campaign is losing visibility due to limited spend, or a dynamic campaign is spending too aggressively on low-intent clicks, a controlled switch can be a low-friction test.

Changing bid strategies in the same campaign is straightforward, but the decision still depends on how fixed and dynamic bidding behave under your specific targets. Once you have performance data from a switch, the broader comparison of fixed versus dynamic strategies can help you decide whether the change supports the campaign’s long-term role.
