: Implementing the hreflang tag in the head When implementing hreflang in the head section, do you call out the alternative and main language on every single page? So for example if I'm implementing

@Radia820

Yes, hreflang links must be identical for all pages in the cluster. And like @Goyllo said, use only 1 version because what you have right now is redundant. Your hreflangs should be like this on both pages:

<link rel="alternate" href="http://example.com/about" hreflang="en" />
<link rel="alternate" href="http://example.com/pt-br/about" hreflang="pt" />

Yes that is how Google know it.

But use only one line out of these two lines,

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


because it is pointing to same URL. I can't say weather it is harmful or not for SEO but if Google have any testing tool for hreflang then it will trigger some error on that. So If your webpage completely written in US English language then keep it first line otherwise choose second one.

Same apply to Portuguese hreflang links. On this Google official article you can see one example about that.


It's a good idea to provide a generic URL for geographically
unspecified users if you have several alternate URLs targeted at users
with the same language, but in different locales. For example, you may
have specific URLs for English speakers in Ireland (en-ie), Canada
(en-ca), and Australia (en-au), but want all other English speakers to
see your generic English (en) page, and everyone else to see the
homepage. In this case you should specify the generic English-language
(en) page for searchers in, say, the UK. You can annotate this cluster
of pages using a Sitemap file or using HTML link tags like this:


<link rel="alternate" href="http://example.com/en-ie" hreflang="en-ie" />
<link rel="alternate" href="http://example.com/en-ca" hreflang="en-ca" />
<link rel="alternate" href="http://example.com/en-au" hreflang="en-au" />
<link rel="alternate" href="http://example.com/en" hreflang="en" />
