Every content field has its own version in every language — in one place, with no duplicated pages.
You do not stand up a separate site for every market. Add a language and switch to it in the editor — the layout stays, the content changes.
The assistant will translate the whole page or a single field. You approve the suggestion — nothing publishes itself.
Each version has its own URL and sitemap entry, so the search engine treats it as a page in its own right rather than a duplicate.
