What is the best approach to have country specific websites?

Hello All,

What is the best approach to have country specific websites?

Our current approach is:

layouts/productname/index/single.html - This file will contain all the content and aslo hreflang for respect language

content/uk/productname/index.md - will have respective params and its layouts points to the above file.
content/us/productname/index.md - will have respective params and its layouts points to the above file.
content/ca/productname/index.md - will have respective params and itslayouts points to the above file.
content/productname/index.md - will have respective params and its layouts points to the above file.

Please share your comments.

Thank you
