seo – Do subdirectories of a domain have their own kind of internal ranking to the point that it matters in which one we publish new content?

Let’s say I have a blog on example.com/blog/ and now I decide to create another blog inside example.com/product/blog/

If example.com/blog/ has been out there for 7 years and its content has been indexed for much longer, would it be better for SEO to keep posting blog posts on it instead of moving some away to some other subdirectory?

Do subdirectories of a domain have their own kind of “internal ranking” to the point that it matters which subdirectory we use to publish our content?
