How to promote a service with subdomains?

Question

Search Engine Optimization

I want to close the main domain from indexing, and open domains like minsk.domain, moscov.domain for indexing. Will it competently close the main domain? The point is that if you go to the main domain, it determines your city by geo location and, depending on this, shows this or that information. Therefore, I want to close the main domain so that there is no repetition of data.

Answer 1

you can close the main domain and work exclusively on subdomains.
The TIC of the main domain will be high. Example bblux.ru
bblux.ru - TIC30(R3)
