Donors or sites on the same IP?

Question

Domain name market

Good evening!
Now we are creating a website - with a huge number of subdomains.
The question is as follows -
one competitor's site (let's call it X) on the link analyzer determines all its subdomains as DONORS.
another competitor site (let it be Y) on the same analyzer defines subdomains as Sites on the same IP.
Tell me, what is the difference and how best to make our site for SEO promotion? If you do not set any parameters, how will subdomains be determined? I understand, as donors?
I will be very grateful for the answer!

Answer 1

What parameters will you set for search robots? :)
If when you go to any page of a subdomain, a 301 redirect is given or the content matches another subdomain, then it will not be considered by the search engine as independent and will be removed from the search results.
Subdomains are needed for a clear separation of sites by content and traffic separation (since the weight is looked at by the fully qualified domain name, the subdomains will be independent of each other).
