Link Map Insights is an admin-side plugin that visualizes the internal link structure of your site in a single click. It analyzes your published posts, pages, and custom post types, then renders the internal links between them as an interactive network graph.

It also highlights isolated content by listing pages that have no inbound links and pages that have no outbound links, helping you improve your internal linking and discover orphaned pages.

Main features:

Generate an internal link map with one click
Filter by post type and taxonomy (categories, tags, etc.)
Node search, zoom in/out, and shortened title display
List of pages with no inbound links
List of pages with no outbound links

The plugin is fully translatable. The admin interface is available in English and Japanese.
