The WordPress plugin for internal linking that never touches your posts

WordPress internal linking plugins traditionally do everything inside WordPress: they scan your posts with PHP on your web server, store suggestion indexes in wp_postmeta, and write links directly into your post content. That architecture has real costs. Large sites see admin slowdowns and database bloat. Links hardcoded into content mean that removing the plugin (or changing your linking strategy) requires editing every post again. And the analysis is limited to whatever your PHP process can manage between timeouts.

Linkagent flips this. The crawl, the topic modeling, the opportunity scoring, and the optional AI review all run in the Linkagent app (hosted or self-hosted) where they can take their time and use a real content model. WordPress only does what WordPress is good at: serving pages. The plugin adds one deferred script tag that injects your approved links at render time by wrapping text that is already in the page. Your post_content in the database is never modified. Deactivate the plugin and your content is exactly as you wrote it.

Setup takes about two minutes: install the plugin, paste your site key, done. From then on it behaves like automated internal linking should. New posts get picked up on every scheduled crawl and linked into your existing content, with anchors taken from sentences you already wrote. It works with any theme and any page builder, because it operates on the rendered HTML rather than the editor markup.
