Where should I place sitemap.xml file in case of fourth level domain (e.g. en.subdomain.example.com)?
All URLs listed in the Sitemap must reside on the same host as the Sitemap. For instance, if the Sitemap is located at http://www.example.com/sitemap.xml, it can't include URLs from http://subdomain.example.com. If the Sitemap is located at http://www.example.com/myfolder/sitemap.xml, it can't include URLs from http://www.example.com.
Does it mean that I should place different sitemap.xml file at the root directory of each subdomain? E.g:
example.com/sitemap.xml - for links ~ https://example.com/path subdomain1.example.com/sitemap.xml - for links ~ https://subdomain1.example.com/path subdomain2.example.com/sitemap.xml - for links ~ https://subdomain2.example.com/path en.subdomain1.example.com/sitemap.xml - for links ~ https://en.subdomain1.example.com/path fr.subdomain2.example.com/sitemap.xml - for links ~ https://fr.subdomain2.example.com/path
Currently I have one sitemap.xml file at the root of https://example.com/, which includes all links from all subdomains.
