I've done a lot of this sort of work for multi-national product marketing and eCommerce sites. There are some good articles documenting best practices. Regarding some of your questions: > - Lack of clarity about SEO rules in this regard. Eg: Will Spanish content rank higher than english one if I search in spanish? Or will google do a combined (transliterated) search and rank the best? If you search the local version of Google (like https://www.google.es/ https://www.google.es/), pages you tag as being for that locale will show up higher. If you search in Spanish on Google.com it'll just match on words... you can still target to Spanish Speakers in the US, for example, using language codes + locale codes (`es-us` for example). - Even if its a non-english website, what are best the practices for URLs? Should they still be in english or can we use the regional language? URLs should be in regional languages whenever possible. Use a subfolder structure though so you can gain domain authority instead of having to re-build it across multiple TLDs.

Way too much tone gets lost in context and tone between sentences. Just write content for each language you intend to serve content to... it's tempting to go with the translation services... but by the time you have a native speaker review the context it's not cheaper than just hiring a native copy-writer / marketing person.
