Do I need to duplicate pages for each language on my Replo site?
Keep one set of pages and store every language’s copy in the translations table.
Languages are set in the Site Builder under Site settings → Languages, where every string on your site lives in one translations table.
No. You keep one page. The translations table holds the copy for every language, so a headline change is one key, not a second page to keep in sync.
