What is the best way to create many subdomains for one site?

Question

Domain Name System

For the site, you need to create several subdomains with different data in meta tags. How to do it better?
1) Create a subdomain folder in the root folder of the site itself.
2) Just create separate folders (not in the root of the site itself)

Answer 1

From a security point of view, each site is best placed in a separate directory.
