Hreflang in country specific XML Sitemaps?

[SimpleSearch]

Hello!

I'm rolling out hreflang tags in my client's "main" XML Sitemap.

My question is:  do we need to implement these tags in the country level XML Sitemaps also?

Thanks!

If you have different content/pages oriented for different regions, yes you need to implement

Hey SimpleSearch–yes, you'll need to indicate these alternate URLs in your sitemap. Google claims that you can use hreflang or sitemaps to indicate international content, but I typically find that being thorough is best (you can always test whether your updated sitemap has made a difference through log file analysis before and after you execute this change).

Here is Google's writeup on indicating alternate pages via sitemap: https://support.google.com/webmasters/answer/189077?hl=en
