Multilingual site, good practices, is it necessary to specify the language in the link?

Question

Internationalization and localization

Hello

If there are several translations of menus on the site, and the translation of the rest of the content in some places is the same, but in some it is not, is it necessary to indicate the language selected by the user in the link? How will Google and Yandex bots work in this case, if the language is automatically selected according to user preferences, or manually, will they parse all translations

Answer 1

It is not entirely clear that you have different pages or that content is being replaced. It’s better to separate everything, so it will be much easier for bots than reinventing the wheel.
