概览
此项评估旨在检查初始非首屏加载的广告是否不超过 3 个。非首屏区域仅在用户向下滚动后才可见。用户看到此区域的广告不太可能被用户看到，因此加载过多此类广告可能会降低可见率并降低网页性能。
建议
延迟加载位于非首屏位置的广告。延迟加载是一种技术，可阻止视口外的广告被请求并呈现，直到广告即将滚动到用户视野范围内为止。如需查看示例实现，请参阅 GPT 延迟加载示例。

The audit checks that no more than three ads are initially loaded in this area, as excessive ads can lower viewability and performance. It's recommended to lazy load ads below the fold, preventing them from loading until they're near the viewport. This technique enhances page performance and viewability. The GPT lazy loading sample is suggested as a way to implement this.\n"],null,[]]
