Google ranking for frequent subdomain changes. 111.site.ru>222.site.ru>333.site.ru?

Question

Google

Good evening, the following question is interesting.
Every day the links on the site "subdomains" of the news change.
i.e. it
was 111.site.ru
changed to 222.site.ru
links to all news automatically change, but when you go to 111.site.ru/news, there is already a redirect to 222.site.ru/news
how much this affects the ranking in google, the site has been indexed for 3 months 508,000 pages, traffic from google is only 200 people at
most
PS we change links due to the need for social traffic (i.e. we bypass the facebook filter, frequent subdomain changes)
example:
active link 3oa8b.bigmall.ge/search/udzra...000-39937.html
before that 328aa.bigmall.ge/search/udzra...000-39937.html

Answer 1

Frequent change of addresses always negatively affects the issuance, because. the old copy is stored in the index for some time.
Plus, frequent domain changes are reminiscent of a doorway.
I can only advise you to use a 301 redirect.
But in general, it is necessary to correct the reputation of the main domain and store news under a permanent address.
This is the first time I hear about the Facebook filter. What do you mean by this?
