How many different domains can be included in the “basic” package? thanks
It includes one Ghost site, but you could conceivable have multiple domains pointing to that site. From an SEO perspective that might not be great, but CNAME records could be configured that way.
From the pricing page (https://ghost.org/pricing/)
All Ghost(Pro) sites come with a free
ghost.iosubdomain by default, and also support the use of any custom domain name via a CNAME DNS record.
