can you tell me please, does adding more languages to the website affect my Seo in the USA search results (English)?
What to choose: sub-directories or sub-domains, ex. fr.example.com VS example.com/fr ?
Thank you.
With our sites at (https://pinkpigeon.co.uk), we use sub-directories, such as example.com/fr.
This guy has some good info (but is a bit spammy with the hard sell): https://neilpatel.com/blog/international-seo/
And here is some more info I have found useful in the past: https://translatepress.com/seo-multiple-languages/
