This is one approach to create multilingual sitemaps. With this method, you have to submit multiple sitemaps to Google Search Console to make sure all URLs are crawled.

  1. I'm using the free version of your awesome plugin "slim SEO"
    What if I have polylang installed but my sitemap.xml is not reproducing the behavior that you describe in this article? When I load the url, I only see the main language pages, and when I inspect the source code for the xml file, there's no way to find these alternate links for the other languages...
    Pages (both languages) are linked properly in order to serve the correct language to the visitor... So I'm not thinking that a misconfiguration of Polylang could be the cause.
    Is there any way to refresh or re-do the sitemap?
    How can I assure the right generation of the sitemap?

  2. Have you checked the "sitemap-post-type-post.xml" sitemap? The main sitemap.xml is an index of sub-sitemaps, which doesn't contain the URLs of other languages. Only sub-sitemaps for post types contain them.

  3. Hi Anh, thanks for your quick answer.
    Yes, I'm aware of what you say. Actually, I'm checking "sitemap-post-type-page.xml" file, since in my website only pages are translated, and there are no posts published.

  4. Finally, with the help of SlimSEO's support staff, I must confirm that everything was working perfectly and the multilingual sitemap was built flawlessly. My confusion was caused by trying to view the alternate links, using Chrome's web inspector, convinced that I was consulting the source code. It wasn't until I printed the source code that I saw the alternate links were indeed there.
    So, I must say: problem solved! Thank you and I apologize for my confusion.
