How do we add Schema Meta Data on Ghost?

Hello, I am planning to switch to Ghost from WordPress, and I have some concerns, could anyone please answer my following questions?

  • How do I add Schema Meta data? On WordPress it’s very simple with FAQ
  • How do I make the blog multilingual?
  • How do I have a focused keyword per article, as, in WordPress, Yoast allows us to use one Focused Keyword.
  • Is it possible to add “Alt tags” to images?
