How to choose the next action
Do not treat one metric as the whole answer. For every change, read the metric beside campaign purpose, search intent, listing readiness, rank movement, and profit. This prevents cutting useful traffic just because one report looks uncomfortable.
If spend is rising but orders, conversion rate, and organic rank are flat, the account needs a wasted spend review before more budget is added.
Start with search terms, not campaigns
The campaign dashboard shows symptoms. The search term report shows the actual shopper language taking your money. Sort by spend and separate terms into four groups: profitable winners, relevant but not converting, irrelevant waste, and unclear terms that need more data.
A search term should not be negated only because it has high ACoS once. Check clicks, orders, relevance, ranking value, and whether the listing is ready to convert that term. A relevant launch keyword can look expensive before rank improves.
Find the main waste sources
| Waste source | What it looks like | Action |
|---|---|---|
| Irrelevant search terms | Spend on terms outside the buying intent | Add negative exact or phrase |
| Broad match overlap | Same query appears in multiple campaigns | Harvest winner and control it in exact |
| Weak placement | High spend on rest of search or product pages with low orders | Reduce placement exposure |
| Poor listing conversion | Relevant clicks but no orders | Fix title, image, price, coupon, reviews, bullets |
Do not cut blindly
The fastest way to lower ACoS is to reduce spend. The smarter way is to move spend from weak traffic into better traffic. If you cut every expensive term, you may reduce visibility on keywords that could drive ranking and future organic sales.
Use ACoS and TACoS together
ACoS tells you how ad sales behave. TACoS tells you whether total account health is improving. If ACoS is stable and TACoS is falling, PPC may be supporting organic growth. If both are rising while total sales are flat, waste is likely building.
