Internal Links to Other Content
The links in this section are included in content of the post you are currently viewing. "Internal" means that these links are pointing to other content within your site's domain.
Inbound Links from Other Content
Other content on your site may point to the item you're currently viewing. By linking your own content within your posts, you help drive traffic to more content. This section, "Inbound Links from Content," helps you identify which posts are linked in other content you've created. If you don't see any links in this section, that means the current post is an "orphan." Orphaned posts are not linked in any other content on your site, which can hurt its overall traffic.
External Links to Other Sites
The links in this section point outward to other sites.
