VOID Technology

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

<h3>Automatic internal linking for WordPress</h3>
<p><strong>BeeClear Smart Link Manager</strong> helps you build internal links between your posts and pages using configurable keyword rules. The plugin injects links dynamically at render time, so your original post content stays untouched in the database.</p>
<p>It is designed for site owners who want better internal linking, stronger topical connections between articles, and a cleaner SEO workflow without manually editing links across the whole site.</p>
<h3>Boost your internal linking</h3>
<ul>
<li><strong>Rule-based automation:</strong> Define phrases and target URLs once, and let the plugin automatically inject matching internal links into your content.</li>

<li><strong>Limit link frequency:</strong> Control how many times a phrase can be linked on a single page to avoid over-linking.</li>
<li><strong>Fast index rebuilds:</strong> Rebuild the link index manually in one click or let the plugin refresh it automatically after post updates.</li>
<li><strong>Import and export:</strong> Move your linking rules between environments without rebuilding everything from scratch.</li>
<li><strong>Clean workflow in wp-admin:</strong> Manage rules from a sortable admin table and use per-post controls where needed.</li>
