How to do multilingual Landing Page?

Question

Search Engine Optimization

Is there a Landing Page in English, how to properly organize multilingualism, so that it does not interfere with promotion in the search engine?
Make a subdomain, or for different languages ​​( https://{langCode}.site.com) or make a separate path ( https://site.com/{langCode})?

Answer 1

It seems to me that a subdomain is better and simpler, just copy the landing page to the subdomain and manually replace the content, if the landing page then the amount of work is small and this is the easiest way
