Is using Ghost ok for SEO?

Using Ghost
1

I have built an angular website and I have used the Ghost API to display the blogs on my site at SHOUT

However, is this going to be ok for SEO?

Or is it better to add my domain into Ghost?

Ghost is great for SEO, but Google doesn’t seem to be indexing shoutugc.com.

3

It’s a brand new website, hasn’t officially launched yet.

The existing website is shout.unitaskr.com

Do you know if it makes a difference to the SEO of the blogs if we use the API to display them on the site, or if we connect our custom domain to ghost.
