Are closed groups indexed in search engines?

Question

Search Engine Optimization

Hello, please tell me, are closed groups of social networks, for example, VKontakte, indexed in search engines?

Answer 1

Not indexed.
Search bots act like "uncle from the street" - an unlogged user. Will this show the contents of a closed group? No.
A special case when the group was open. Indexed. Then the admin decided to "suddenly" make it closed. Made. And the search cache remained.
PS You can check if your secret closed group is indexed by querying Google and Yandex:site:vk.com/vasha_sekretnaya_gruppa
