Repository metrics are context, not quality scores. Active installations measure adoption and can strongly reflect a plugin’s age and historical popularity. Ratings, recent updates and “Tested up to” metadata also do not guarantee modern code, error-free operation, security, feature completeness or suitability for a particular site.

WP PlugIndex currently records RK – Smart Internal Linker version 1.0.0 as active, updated 8mo ago and tested up to WordPress 6.9.
Overview
About this plugin
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
