seo – Links to the site root versus separate subpages

From an SEO perspective, are the backlinks to the root of your domain different from the links to subpages? That is, example.com versus example.com/widget1, example.com/widget2 and example.com/blog/topic1.

I have a relatively new site and I have managed to get some backlinks, but they almost always point to the root of my domain, rather than to my content or my blog posts.
