Yandex Webmaster new site?

Question

Search Engine Optimization

Good afternoon.
Is there any difference how to add a new site to Yandex Webmaster
1). https://www.site.org
2). www.site.org
I just got a warning about "gluing mirrors" there

Answer 1

If the domain is with https then 1 option

Answer 2

I just got a warning about "gluing mirrors" there.

So urgently, you need to buy, break and glue.
But seriously, register, the main option that you will use, indicate the second as a mirror.

Answer 3

If the site is set to https, i.e. a certificate is installed and redirects are set, then in robots.txt specify the directive Host: https://sitename.ru and when adding to Webmaster immediately add with https. Otherwise, you will lose time later, while Yandex will bypass, glue, check.
