如何动态更改网页的标题?

我有一个网页，实现了一组选项卡每个显示不同的内容。单击选项卡不会刷新页面，而是隐藏/取消隐藏客户端的内容。

现在需要根据页面上选择的选项卡更改页面标题(出于SEO原因)。这可能吗?有人能建议一个解决方案，通过javascript动态改变页面标题，而不重新加载页面?

Google mentioned that all js files rendered but in real, I've lost my title and another meta tags which had been provided by Reactjs on this website and actually lost my position on Google! I've searched a lot but it seems that all pages must have pre-rendered or using SSR(Server Side Rendering) to have their SEO-friendly protocole! It expands to Reactjs, Angularjs , etc. For short, Every page that has view page source on browser is indexed by all robots, if it's not probably Google can index but others skip indexing!

由于搜索引擎忽略了大多数javascript，因此您需要使搜索引擎能够使用标签而不使用Ajax进行抓取。使用href将每个选项卡设置为链接，以加载选中该选项卡的整个页面。然后页面可以在标签中包含该标题。

onclick事件处理程序仍然可以通过ajax为人类查看者加载页面。

要像大多数搜索引擎看到的那样查看页面，请关闭浏览器中的Javascript，并尝试使其具有这样的功能，即单击选项卡将加载选中的选项卡和正确的标题的页面。

如果你通过ajax加载，你想用Javascript动态地改变页面标题，那么做:

document.title = 'Put the new title here';

但是，搜索引擎不会看到javascript中所做的这个更改。

更新:根据SearchEngineLand上的评论和参考大多数网络爬虫将索引更新的标题。下面的答案是过时的，但代码仍然适用。

You can just do something like, document.title = "This is the new page title.";, but that would totally defeat the purpose of SEO. Most crawlers aren't going to support javascript in the first place, so they will take whatever is in the element as the page title. If you want this to be compatible with most of the important crawlers, you're going to need to actually change the title tag itself, which would involve reloading the page (PHP, or the like). You're not going to be able to get around that, if you want to change the page title in a way that a crawler can see.

为了让任何爬虫程序注意到这个变化，您必须用一个新的标题重新提供页面。通过javascript这样做只会让人类读者受益，爬虫不会执行这些代码。

最简单的方法是从index.html中删除<title>标签，并包含

<head>
<title> Website - The page </title></head>

在网络的每一页。蜘蛛会发现这一点，并将显示在搜索结果:)
