Content of spaces not show to all people

Hi! I'm trying to understand how the plugin works in terms of SEO.

I created a post like this:
https://domain.com/portal/space/recur/post/font-awesome-features/

I want this content to be publicly accessible to everyone and also indexed by Google.
Is that possible?

If I access to the post url now I watch only heather and login/register buton. Thanks in advance!
