Satellite network or just sites?

Question

Search Engine Optimization

So, I have:
The domain name site1.ru and many subdomains, each with a completely different theme.
Let's say these subdomains site2.site1.ru, site3.site1.ru, site4.site1.ru and so on.
At the same time, all subdomains are on the same hosting and made on the same cms, but on different templates (well, they are different, very similar, but slightly different).
As you can see, I am not trying to hide from the PS that I own all these sites, but I see no reason for any sanctions, because each of them has unique content on its own subject.
Yes, I have already read that satellite networks must be registered with different registrars, lie on different hostings and be made on different CMS. But I still don’t understand if my creation is a network of satellites or is it just a lot of independent sites with a 3rd level domain name?
Therefore, I want to ask questions on the concept described above. Do I understand correctly that:
1) as long as they do not have common links to each other and other resources, the PS will consider them separate sites?
2) is it possible to link to each other in the articles of these sites without fear of sanctions?
3) can you make links to all these subdomains from the main site.ru domain without fear of sanctions?
4) wouldn't an external link from any of these sites to another make them a satellite grid and result in sanctions?
Those. site2.site1.ru has topic 2 and links to another site with the same topic. I'll call it site2.rf.
Will the PS consider that site2.rf is being promoted by a grid of satellites (we remember that site2.site1.ru can receive links from site3.site1.ru and site4.site1.ru) or will it be considered as a regular link from a regular site ?

Answer 1

Subdomains - not exactly regarded as a grid of satellites. This concept (network of sites) means the registration of dropped domains and the creation of sites on them specifically for the promotion of some kind of main resource. Primarily. What you want to do is the place to be in general. Many top competitors in a particular niche practice this when the topics do not intersect with each other in any way, or, for example, if the main pages are ranked in the TOP for the necessary queries. Here is an example from Runet, which I somehow came across prntscr.com/iambd8
You can see how its pages are linked and take an example into service. I can't come up with a linking scheme so quickly. This is a long process of analysis needed.

Answer 2

If you make them for links, and they will still refer to themselves, then this will not give you Profit, if these are just working sites, then it doesn’t matter.
