异步加载广告代码
概览
此项审核旨在确保异步加载广告代码库脚本。
默认情况下,JavaScript 执行是同步的。也就是说,脚本
则在该脚本完成之前,不能加载其他内容。
已下载、解析和执行。选择启用异步执行可防止
这样,浏览器在
指定的脚本在后台加载。这样可确保您的网页在脚本加载期间仍能灵敏地做出响应,并缩短所有关键组件的加载用时。
建议
在脚本代码定义中添加 async 属性。例如:
AdSense
<script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>
AdSense(自动广告)
<script async data-ad-client="ca-pub-xxxxxxxxxxxxxxxx" src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>
Google 发布商代码
<script async src="https://securepubads.g.doubleclick.net/tag/js/gpt.js"></script>
支持以下广告代码库脚本:
