We need to deploy 2 websites :
https://in.example.org (Server in India)
https://usa.example.org (Server in the USA)
we will be defining the href-lang tag for both websites in the Sitemap.xml
However, I am not sure if I need geo routing when people in the USA search for "example.org"
We want that when users in USA search for example.org - they should head to the USA website https://usa.example.org
whereas any user in the rest of the world search for example.org should head to the India website https://in.example.org
