How to make a bilingual site on two domains and not run into search engine sanctions?

Question

Google

I started translating the site into a second language, a version on a different domain. Now the English version, of course, has a lot of Russian text. I read that it is necessary to give links to translations,
but how else to explain to search engines that the English version is a conscious clone of the Russian one and should not be considered that this is a duplication of content? everything will be translated for a long time, but I would like at least the main one to appear in the search and when requested in English.

Answer 1

Not sure what is possible. It would be better if they did, for example, yourdomain.com/en and yourdomain.com/ru, then everything would be decided by a simple description in robots.txt

Answer 2

Just lay out the product in parts. The English version should not have freely available pages that have not yet been translated. All of them should be temporarily 404.

Answer 4

If you decide that each language will be promoted on a separate domain, then at least link the domain to different countries in Google Webmaster - .
