Automatic and manual Amazon Ads campaigns can serve different purposes. The right structure depends on the seller's product economics, search-term evidence, placement results, inventory, and approved objectives; no campaign type universally produces a better ACoS.
Define each campaign's purpose
Document whether a campaign is for discovery, a validated query, branded coverage, product targeting, or another client-approved purpose. Keep reporting legible enough to explain where spend and attributed sales came from.
Review search terms
Use seller-authorized search-term and bulk reports. A candidate movement from automatic or broad discovery to a manual campaign should state the source period, product margin, match type, current result, proposed bid and budget, and the reason. A cheap click or one attributed order is not universal proof of repeatable demand.
Use negative keywords carefully
Review product intent and campaign purpose before adding a negative. Record the affected campaign, match type, evidence, and approver. Human review is required because an automated candidate can block relevant traffic.
Measure the approved change
Agree a suitable review period based on traffic, attribution, seasonality, and data quality. Compare ACoS, TACoS context, spend, attributed sales, and contribution assumptions without claiming that one structure caused all movement.
