What Core+ Links is

Core+ Links is a self-hosted WordPress plugin for finding and managing internal links through a local index of site content. In the Gutenberg block editor, a sidebar ranks possible destinations using eight weighted signals and displays match strength. Users can revise suggested anchor text, insert a link in one click, or dismiss a suggestion. Keyword rules scan pages for matching text, with users reviewing and confirming proposed links before they are applied.

A change history allows users to undo a single edit, a full run, or links added through a keyword rule. Reports identify orphan pages with no inbound internal links and underlinked pages with fewer inbound links than their importance calls for. Link Health finds internal links that point to unpublished, trashed, or missing pages; it does not check external URLs over HTTP. Free indexing, ranking, auto-linking, and Link Health run on the site's own server and database without sending content to outside services.

The permanent free plan includes posts and pages, block editor suggestions, review-first auto-linking, Link Health, reports, background indexing, and scheduled reindexing. Upcoming Pro plans describe AI-assisted matching with a provider key, custom post types and fields, external HTTP checking, and other additions. Core+ Links is made by Core Local SEO, based in Florida, United States.
