问题描述
Google 给了我一段 javascript 并告诉我将它包含在 <head> 中.
Google gives me a piece of javascript and tells me to include it in the <head>.
我可以把它放在的末尾，否则会产生一些副作用吗?
Can I put it at the end of <body> or will some side effects occur if I do that?
推荐答案
将它放在 <head> 部分的末尾有助于确保即使用户没有跟踪您的指标让页面完成加载.
Putting it at the end of the <head> section helps ensure the your metrics are tracked even when a user doesn't let the page finish loading.
在他们添加对处理页面部分加载的支持之前，他们曾经告诉你把它放在页面的底部.
They used to tell you to put it at the bottom of the page, before they added support for handling partial loading of pages.

One of the main advantages of the asynchronous snippet is that you can position it at the top of the HTML document. This increases the likelihood that the tracking beacon will be sent before the user leaves the page. It is customary to place JavaScript code in the
<head>section, and we recommend placing the snippet at the bottom of the section for best performance.
