Is multilingualism and multidirectionality good on the site?

Question

Search Engine Optimization

Let's say I have a website - news, entertainment, a forum on various topics, plus everything, all pages are automatically translated into other languages, that is, some news is written and if you switch the language, it will already be in the selected language, and the comments are also translated .
Question - is it good in terms of website promotion in search engines?
The fact is that I read several articles on this issue and the following was written there - if the site is in one language, then it will more often appear on requests in this language than a multilingual site. Also, if the site is exclusively about cars (for example), then it will come across in the query results more often than a site where there is the same information, but besides it there is a lot of other information not related to this topic.
Although there were topics where it was described differently ...
Here I would like to ask a question - what is better for search engines, given that everything happens on the same domain, and when switching the language, only /ru/ or /en/ changes in the address bar, etc. ?

Answer 1

Everything is relative: either you catch high-frequency queries with a “network” (multilanguage, many pages, many keys), or immediately target audience with a “harpoon” (one language, few pages, few keys).
1st type: gets more often in the search results, but not in the 1st position.
2nd type: it gets into the search results much less often, but more often in the 1st position.
The choice depends on the direction, the target audience and the logic of your "funnel" of retaining the visitor (with further profit).
I would advise you to distribute the shares of keys on one domain in this way (language, sections, etc. - do not play a role):
High-frequency - 2/3
Low-frequency - 1/3
The more competition - the more we shift towards high-frequency and select more carefully keys in all parts.
