How does the incomplete translation of a site from ENG to RU affect SEO?

Question

Search Engine Optimization

The site is in Eng, but what if you screw the Russian interface as the choice of the Russian language?
Will Google consider such a site bad? After all, some of the content will be in English

Answer 1

What is the purpose of such manipulations? If they do multilingualism, then it is necessary to translate the interface and content, and make language subfolders in the normal way.
Without a normal full translation, you should not expect a good return in terms of ranking
