Does it matter that there are several sites of the same theme on one hosting?

Question

Search Engine Optimization

Hello.

Tell me, please, can it be that if two sites of similar topics are hosted on the same hosting on the same IP, then they are somehow pessimized in search engines? Plus, these sites are also on the same account in Webmaster and Google Console.

Answer 1

If sites of similar subjects have the same contact information on the site, ip, whois and other data, then they may be affected by the affiliate filter

Answer 2
