减少与广告相关的布局偏移
概览
Cumulative Layout Shift 通过使用 Layout Instability API 来衡量用户可见的布局偏移的总量，方法是汇总广告 iframe 发生布局偏移或导致布局偏移的所有布局偏移的布局偏移得分。
建议
此指标不代表具体问题。它应该用于帮助找出有待改进的领域并跟踪一段时间内的改进。
为避免布局偏移，请务必在广告代码加载之前为广告元素设置尺寸。这种做法可能很难实现或无法完美实现（尤其是对于接受动态尺寸广告的广告位），但在大多数情况下，您可以遵循一些最佳做法来尽可能减少布局偏移。如需了解详情，请参阅 GPT 开发者网站上的与尽可能减少布局偏移有关的指南。
