URL Autolinker by Jerin.ca automatically converts your saved keywords (aliases) into links inside your content. 
Add a URL, assign one or more aliases, and the plugin will link those aliases when they appear in your posts/pages. 
Each saved URL can have its own link behavior (open in a new tab, nofollow), and you can export/import your Saved URLs to move rules between sites.
If you want advanced controls and AI-powered internal-link suggestions, an optional Pro upgrade is available. 
Pro adds powerful content controls, exclusions, limits, performance options, and AI Links (Smart Suggestions + Zero-Link Posts) so you can plan internal linking faster.
Free Features: 
– Save URLs with one or more aliases (keywords). 
– Automatically link aliases to the saved URLs in post content. 
– Per-link options: open links in a new tab, add nofollow. 
– Export and import your Saved URLs.
Pro Features (Available Now): 
– Link limits (per-alias per-paragraph, and total links per post). 
– Post type whitelist + post/page blacklist controls. 
– Exclude HTML areas (headings, lists, tables, code, etc.). 
– Optional: skip targets already linked manually. 
– Optional: cache compiled rules for faster performance. 
– AI Links: Smart Suggestions — analyzes a full post/page and suggests internal links (target + anchor words). 
– AI Links: Zero-Link Posts — helps identify posts/pages that likely need internal links. 
– Review-first workflow — you choose what to save/apply. 
– Save selected AI suggestions into Saved URLs for consistent auto-link rules. 
– License status + Pro enable/disable toggle.

VOID Technology

Linkable is a lightweight WordPress plugin that automates internal linking by converting defined keywords into links to selected posts or pages.
Core functionality: 
* Automatically links keywords to chosen posts or pages 
* Works on singular posts and pages by filtering <code>the_content</code> at priority 20 
* Searches for keyword matches inside <code></code>, <code><li></code>, <code></code>, <code></code>, and <code></code> tags 
* Skips self-links by excluding the current post from the keyword map 
* Uses the Yoast SEO title for link tooltips when Yoast is active, otherwise falls back to the WordPress title 
* Preserves existing <code><a></code> tags and shortcodes by backing them up before processing and restoring them afterward
Keyword management: 
* Keywords are stored per post and per page as JSON in the <code>linkable_tags</code> post meta field 
* <code>linkable_tags</code> is registered with REST support, sanitized via <code>sanitize_text_field</code>, and restricted to users with <code>edit_posts</code>
Settings: 
* Accessible via Settings → Linkable 
* <code>max_links_per_target</code>: limits how many times the same target can be linked from one post (default 1) 
* <code>first_occurrence_only</code>: when enabled, each keyword is linked only once per post
Performance: 
* Builds a global keyword map from all published posts and pages with <code>linkable_tags</code> 
* Caches the keyword map with a transient (<code>global_linkable_tag_map</code>) for one hour 
* Query optimized to fetch only IDs and avoid unnecessary meta/term caching
Editor compatibility: 
* Works with both the block editor and the classic editor 
* Enqueues an admin sidebar panel script (<code>static/js/admin-sidebar-panel.js</code>) with WordPress dependencies and versioning via <code>filemtime</code>
Security: 
* URLs are properly escaped with <code>esc_url</code> 
* Link titles are sanitized and HTML-escaped 
* Meta registration includes capability and sanitization checks

I love it, when plugins doesn't get bloated with things not related to the task at hand. This just does the job, plain and simple.


Simple but functional

Automatically link keywords in your content to internal pages or posts. Simple, fast, and Gutenberg-compatible.
