Core+ Links vs Smart Internal Links

Core+ Links is a self-hosted WordPress plugin that finds and manages internal links using a local index of site content. In the Gutenberg block editor, its sidebar ranks possible destinations with eight weighted signals and shows match strength. You can revise anchor text, insert a suggestion in one click, or dismiss it. Keyword rules scan pages for matches that you review before applying. A change history can undo one edit, a complete run, or links created by a keyword rule. Reports identify orphan pages without inbound links and underlinked pages with fewer links than their importance calls for. Link Health flags links to unpublished, trashed, or missing pages, but does not inspect external URLs over HTTP. Indexing, ranking, auto-linking, and Link Health run on your server and database. The free plan is permanent and includes background indexing and scheduled reindexing. Requirements are WordPress 6.6+, PHP 7.4+, and Gutenberg. Upcoming Pro plans have no listed prices.
