What steps should I proceed to tell Google about my migration from HTTP to HTTPS (there is 301 valid redirect is set), nothing I can see in Google webmaster (they have migration, but it is saying they do not support such migrations). Eventually I just setup ssl cert and set nginx accordingly and after two weeks I see nothing indexed and nothing in search. Is this expected?
Also, how bad for SEO subdomain.domain.com? Domain goes to subdomain.domain.com with 301 redirect..
