hreflang应该如何构建？ [英] How the hreflang is supposed to be built?

问题描述

我的问题是

 < link rel =alternatehref =http://example.com / enhreflang =en> 
< link rel =alternatehref =http://example.com/ithreflang =it> 
  

应该像上面的所有页面一样，或者应该用每个页面的实际url更改：

 < link rel =alternatehref =http://example.com/en/<?=$current ;？>中的hreflang = EN > 
    

解决方案

HTML5 定义：

如果替代关键字与 hreflang 属性，并且该属性的值与根元素的语言不同，它表示所引用的文档是翻译。




翻译文档（即网页），而不是网站。 http://example.com/en code>链接至 http://example.com/it ，

http://example.com / en / hello 链接至 http://example.com/it/ciao 。

My question is does the

<link rel="alternate" href="http://example.com/en" hreflang="en">
<link rel="alternate" href="http://example.com/it" hreflang="it">

should be like above an all pages or should be changed with the actual url of every page like:

<link rel="alternate" href="http://example.com/en/<?=$current;?>" hreflang="en">
<link rel="alternate" href="http://example.com/it/<?=$current;?>" hreflang="it">
<link rel="alternate" href="http://example.com/<?=$current;?>" hreflang="x-default">

解决方案

HTML5 defines:

If the alternate keyword is used with the hreflang attribute, and that attribute's value differs from the root element's language, it indicates that the referenced document is a translation.

So it’s for translated documents (i.e., pages), not sites.

http://example.com/en links to http://example.com/it,
http://example.com/en/hello links to http://example.com/it/ciao.
