Is it correct to use subdomains like this?

Question

Search Engine Optimization

The project has a website with pictures. I don't really want to keep everything on one site. I want to divide by topics and take them out separately by subdomains.
Will it be right or not?
Example:
art.site.ru
abstraction.site.ru
people.site.ru
hous.site.ru
and so on.
Will search engines respond adequately?

Answer 1

Yes, it’s quite possible, after all, you will then set up cross-references within projects and everything will be top type.
Previously, even search engines gave some of the weight of the subdomain to the main domain. Now I don't know, I haven't played like that in a long time. As a minus - you will have exactly as many engines as subdomains, do I understand correctly? Everyone will have to update and follow.

Answer 2

We talked about the pros above, but missed a significant minus.
There is a theme of the domain. Those. how fully information is disclosed on the domain. If you take some electronics store, for example, mvideo. Why don't they make separate subdomains for refrigerators, separately for microwave ovens, etc.?
Perhaps you have a specific case, but from your wording of the question, I would not advise you to do this.

Answer 3

In the context of the problem of pictures - I don’t really understand the meaning of the reluctance to store them in one project on one domain. Subdomains can help in situations with regions, and sometimes, in situations with themes. In your case, a gallery site can easily contain various thematic sections, because these are graphics (one common theme). I would not advise you to bother with subdomains.
