Just to take it as a separate stream of income, when hit just one website is hit, others continue to bring the profits. Also helps to stay organised with monetization. Maybe more work but worth itBut why not to do different language mutations (domain.com/es/ or es.domain.com/) on the same domain?
That would mean less expenses (1 domain instead of N domains), as well as higher authority of that particular domain (more articles, more pages).
Honestly can't see a reason why you'd go for more domains...
That should work as it is not duplicate content. And if the translation is good and users like your content it should rank.
Cool thanks. It is duplicate content if I use Google translate, but I won't be using GT
