ACoS and TACoS definitions
ACoS is ad spend divided by ad sales. TACoS is ad spend divided by total sales. ACoS tells you how efficiently ads convert. TACoS tells you whether ad spend is healthy compared with the whole product revenue.
| Metric | Formula | Best use |
|---|---|---|
| ACoS | Ad spend / ad sales | Campaign-level efficiency, bid decisions, keyword cleanup. |
| TACoS | Ad spend / total sales | Account health, organic growth, launch trend, budget planning. |
Why TACoS matters during a launch
In a launch, ACoS may look high because the product is still building conversion history and organic rank. If TACoS improves over time while organic sales share increases, PPC may be doing its job even if ACoS is not yet beautiful.
When TACoS gives a warning
If TACoS rises for weeks while ranking does not improve, the account may be buying traffic without building organic demand. That is when campaigns need a deeper review: search terms, keyword relevance, CPC, conversion rate, price, reviews, coupon, and listing quality.
Use ACoS to fix campaign waste. Use TACoS to decide whether the overall advertising system is helping the product become stronger.

- Review TACoS by ASIN, not just account total.
