Simple Link Embed

Description

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:

  • WordPress Block (Gutenberg) Support – Fully compatible with modern block editor
  • External and Internal Links – Paste an external URL or search for an internal post from the editor
  • Automatic Metadata Fetching – Retrieves OGP and fallback metadata from the selected page
  • Card Display Controls – Control image position, description, site name, and link target behavior
  • Site Favicon with Fallback – Uses the linked site’s favicon when available and falls back to a bundled icon
  • YouTube and X Support – Includes service-specific metadata handling and fallbacks
  • Optional GA4 Click Tracking – Sends click events only when explicitly enabled
