Blog on Shopify vs Ghost for SEO

Hello,

Hoping someone can give some advice here.

We currently have a Shopify store but not a blog to back it up, what’s your opinion on having a Ghost blog embedded into our Shopify store VS having the blog directly feed from Shopify.

We’d love to use ghost for blogging and embed it into our store but we are afraid this will negatively affect our overall SEO ranking on our Shopify store.

Do we blog direct using Shopify or go with the Ghost theme and embeded the page?

Another reason we don’t want to use Shopify is that their blogging templates suck!

Thoughts?

Thanks for your time.
