Does content in two languages ​​affect promotion?

Question

Domain Name System

Hello.
There is 1 site about English. It is in the .ru zone
. Will it have a negative impact on promotion if the content is in Russian site.ru/, and in English site.ru/en/ or en.site.ru/
English content on the domain is planned to be sharpened for Adsense.
Or is it still better to delimit Russian content and not mix it with English, and do English content on a separate domain such as the .com zone

Answer 1

it’s enough en.site.ru/
you can’t mix on one
, however, Google already doesn’t care, but still structured is better
