RK – Smart Internal Linker

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:

1. On activation, the plugin creates a keyword index table and begins indexing your published posts via WP-Cron (20 posts every 5 minutes).
2. When you open a post in the editor, the plugin extracts the top keywords and scores every other post by keyword overlap (TF-IDF).
3. 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
