A high ACOS can feel like a warning light, but it is only a ratio. Before you cut budgets, it helps to know which part of your spend is actually leaking money and which part is quietly building your rank.
Quick Comparison: Campaign Types
| Factor | Launch | Defend | Profit |
|---|---|---|---|
| Main goal | Visibility and reviews | Protect brand terms | Maximum margin |
| Typical ACOS | Above break-even | Low | At or below break-even |
| Bidding | Aggressive | Moderate | Tight, exact match |
| Review cadence | Daily | Weekly | Weekly |
These are typical tendencies, not guarantees.
Start with your break-even ACOS
Your break-even ACOS is the point where ad spend consumes your entire margin on a sale. Calculate it from your price, fees, cost of goods and shipping. Any campaign sitting below that number is profitable on its own; any campaign above it needs a reason to exist, such as launching a new product or defending a keyword.
Clean up the search term report
The search term report is where most wasted spend hides. Review it every week and act on what it shows:
- Add clicks-without-orders terms as negative keywords once they have enough data.
- Move proven converting search terms into their own exact-match campaign with a tighter bid.
- Separate branded, competitor and generic terms so one cheap term cannot hide an expensive one.
Fix the listing before you fix the bid
If shoppers click but do not buy, lowering bids only reduces the symptom. Check your main image, title, price against competitors, review count and bullet points. A stronger listing raises conversion rate, and a higher conversion rate lowers ACOS on every campaign at once.
Bid by placement and by goal
Top-of-search placements often convert better but cost more. Adjust placement modifiers based on your own data rather than defaults, and keep launch, defend and profit campaigns separate so each one is judged against the right target.
Lowering ACOS is a steady, weekly routine rather than a one-time fix. If you would rather have a specialist team run it for you, that is exactly what we do.
