RK – Smart Internal Linker

Por Rajkumar

Descripción

RK Smart Internal Linker analyzes your content in real time and suggests the most relevant internal posts to link to — right inside the Gutenberg sidebar. No external APIs, no monthly fees, no data leaving your server.

How it works:

On activation, the plugin creates a keyword index table and begins indexing your published posts via WP-Cron (20 posts every 5 minutes).
When you open a post in the editor, the plugin extracts the top keywords and scores every other post by keyword overlap (TF-IDF).
The top 5 results appear in a sidebar panel with Copy Link and Insert Link buttons.

Features:

100% local — no API keys, no external calls
TF-IDF keyword scoring for smart relevance
Background indexing via WP-Cron (server-friendly batches)
Instant re-index on post save
Clean Gutenberg sidebar with score badges
One-click copy or insert links
