## Definition
|
||
|
||
ACOS（Advertising Cost of Sales，广告成本占销售额比例）是衡量亚马逊 PPC 广告效率的核心指标，计算公式为：`ACOS = 广告花费 / 广告带来的销售额 × 100%`。ACOS 越低，表示广告效率越高。
|
||
|
||
## Formula
|
||
|
||
```
|
||
ACOS = (广告花费 / 广告带来的销售额) × 100%
|
||
TACOS = 总广告花费（含站内外）/ 总销售额 × 100%
|
||
```
|
||
|
||
## Interpretation
|
||
|
||
| ACOS 区间 | 含义 | 适用阶段 |
|
||
|-----------|------|----------|
|
||
| < 15% | 高效广告 | 成熟期产品，利润率充足的品类 |
|
||
| 15-25% | 健康范围 | 成长期产品，平衡增长与利润 |
|
||
| 25-35% | 可接受 | 新品推广期，侧重增长 |
|
||
| > 35% | 需优化 | 超毛利率则必须关停或大幅调整 |
|
||
|
||
## Key Principles
|
||
|
||
- **ACOS 硬性底线**：任何超过毛利率的广告活动必须优化或关停
|
||
- **TACOS < 10%**：成熟期产品目标，反映广告依赖度降低
|
||
- **分阶段调控**：新品期允许高 ACOS 换增长，成熟期压低 ACOS 保利润
|
||
- **负关键词策略**：持续否定非转化词，降低无效花费
