<ul>
<li>url : (mandatory) URL to link</li>
<li>bgcolor : (option, default: #fff) background-color of the link tile.</li>
<li>nocache : (option, default: false) set to true once if the linked page is changed.</li>

Open Graph link tile

This WordPress plugin makes a link tile from Open Graph protocol.

MONOKURO DESIGN

Simple Link Embed lets editors create link cards from external URLs or internal posts in the block editor. Paste a URL or search for a post, and the plugin fetches metadata such as the title, description, image, and site name automatically.
When an editor inserts or refreshes a card, the plugin requests the selected URL from the server side to fetch metadata. Preview images and site favicons are still loaded from the linked site when available.
Features:
<ul>
<li>WordPress Block (Gutenberg) Support – Fully compatible with modern block editor</li>
<li>External and Internal Links – Paste an external URL or search for an internal post from the editor</li>
<li>Automatic Metadata Fetching – Retrieves OGP and fallback metadata from the selected page</li>
<li>Card Display Controls – Control image position, description, site name, and link target behavior</li>
<li>Site Favicon with Fallback – Uses the linked site’s favicon when available and falls back to a bundled icon</li>
<li>YouTube and X Support – Includes service-specific metadata handling and fallbacks</li>
<li>Optional GA4 Click Tracking – Sends click events only when explicitly enabled</li>
</ul>
