<link rel="alternate" hreflang="lang_code"... > indicates that the referenced document is a translation according to the HTML spec.

It is also mentioned in https://developers.google.com/search/docs/advanced/crawling/localized-versions

Should we mention it in one of our navigation articles, like Guiding users to translated pages?

Does it have any effect? Particularly, for non-Google search engines?

Note, also, btw, that to implement this we'll probably need to add code to every article page (including all translations), to anchor the location for the markup we'd generate from the template.

It helps search engines index and serve the localized version of a web page to users. See the docs below:

• Google
• Yandex
• Bing

Yes, sorry my question was a little too brief. I understand the principle of how it is supposed to work, but i was wondering whether we are able to confirm that it does in fact produce results. And if it does produce results, for how many search engines? (Useful to see that Yandex and Bing may use the information. That makes it seems less of a proprietary hack, but do we know of others.)
