Add an SEO friendly blog to an InertiaJs Vapor Site

I'm trying to think of a nice way to add a blog to an Inertia site, where the blog isn't using inertia. I'd like to get a vue, laravel or markdown friendly CMS involved too if possible. Does anyone have any neat ideas?

One idea I have is to use a subdomain, blog.site.com, and have that whole thing in a subfolder with it's own vapor.yml, but this seems like it might be overkill, and has the drawback of needing its own environment...
