Auto Target ACOS
Aggressive / Budget-Focused
Maximize Growth & Spend
This strategy helps you capture additional traffic and conversions while maintaining overall budget control. Use Auto Target ACOS when you want more data, more traffic, and faster growth.
Expected Performance
Higher spend / budget utilization
More impressions and clicks
More total orders (volume growth)
ACOS may fluctuate or be higher than target especially early stage
Faster learning and data accumulation
Best for Following Campaigns
1. New campaigns: auto helps kickstart performance
No historical data yet
Need traffic and data quickly
System needs signals to optimize
2. Under-spending campaigns: auto increases bids to unlock traffic
Budget not being fully used
Low impressions / low clicks
Ads inactive for long periods
3. High ACOS but low volume campaigns: auto helps test and explore more opportunities
ACOS is high but impressions and orders are low because there is no enough data, not just inefficiency
4. Scaling / growth phase: auto pushes volume
Product already converting
Want more orders and revenue
Okay with some ACOS fluctuation
5. Seasonal / promotional periods: auto helps capture demand
Prime Day, holidays, launches
Traffic matters more than strict efficiency
☛ Campaigns with Auto Target ACOS allow at least 5–7 days for initial performance, and 10–14 days for more reliable optimization. If those campaigns still don't performance well after 14 days, it usually means the issue is not bidding but campaign fundamentals.
Manual Target ACOS
Conservative / Cost-Focused
Maximize Efficiency and Control
This strategy helps you get more efficient spending and stable costs, but less aggressive growth. Use Manual when you want predictability, efficiency, and cost control.
Expected Performance
More stable and controlled ACOS
Lower or more efficient ad spend
Fewer impressions and clicks (compared to Auto)
Potentially lower total orders
Slower scaling but more predictable performance
Best for Following Campaigns
1. Mature campaigns: manual helps optimize efficiency
Consistent conversion rate
Predictable performance
2. High-spend campaigns: manual protects profitability
Already spending a lot
Small inefficiencies = big cost impact
3. High ACOS + high spend campaigns: manual tightens bids to bring ACOS down
Spending a lot but inefficient
4. Profit-sensitive products: manual helps control cost
Low margins
Strict profitability requirements
5. Well-defined ACOS targets: manual follows that target precisely
seller knows exact breakeven / profit ACOS
