## Definition
广告可见性Viewability是衡量数字广告是否被真实用户看到而非仅仅被加载但不可见的指标。MRCMedia Rating Council定义了最低可见性标准展示广告至少 50% 的像素在屏幕上停留 1 秒以上Video 广告至少 50% 像素停留 2 秒以上。
## Industry Standards
| 标准制定方 | 要求 | 说明 |
|-----------|------|------|
| MRCMedia Rating Council | 50%/1s展示/ 50%/2s视频 | 最低行业标准 |
| GroupM | 50%/2s | 更严格的可见性标准 |
| Google Active View | 70%+ 可见展示 | 通常作为活动基准目标 |
## Why Viewability Matters
- **防止广告位欺诈**:仅仅加载广告不等于用户看到了
- **品牌安全**:低可见性位置往往与低质量内容相关联
- **效率优化**:将预算从低可见性位置转移到高可见性位置
- **归因基础**:只有可见的展示才可能驱动品牌认知和转化
## Optimization Levers
- **Placement Exclusions**:排除低可见性广告位
- **Viewability Targeting**:在 DSP 中直接设定可见性门槛竞价
- **Supply Path Optimization**:优先选择已知高可见性发布商的交易路径
- **Format Selection**大尺寸格式300x600、970x250通常可见性更高
## Success Benchmark
- **目标指标**≥70% MRC 标准可见展示率
- **低于此标准的位置**:考虑降低出价或排除
