Choosing a bidding strategy is a controls decision. Begin with the settings a person wants to review and the evidence available for that campaign.
Describe the selected mechanism
Amazon distinguishes fixed bidding from dynamic bidding that can lower bids or raise and lower them in supported situations. Placement adjustments also matter. Check the current documentation and available account options. Amazon’s Sponsored Products bidding strategies.
Record the strategy exactly as it appears in the account. Keep the base bids, placement settings and campaign budget together. A strategy name alone does not describe the full spending controls.
State the reason for choosing
Write the product, objective, cost assumptions, report period and owner’s spending limit. Identify whether the proposed change is to the strategy or to another setting. Avoid changing several controls together without recording the combined proposal.
Keep uncertain inputs visible, including product availability and recent results whose attribution period remains open.
Make the review reproducible
A person applies the agreed setting and checks what was saved. Retain the previous version, the date and the reason for the decision.
At the review date, use the same metric definitions and record any other campaign or product changes. The result informs the next decision for that campaign; it does not establish a winning strategy for every account.
