YouTube Link Card WP Registry grade A. No security issues foundWP RegistryNo security issues foundOpen the reportA

A WordPress plugin that renders styled YouTube link cards — single videos, playlist grids, and channel banners — without loading the heavy YouTube iframe player. Cards link out to YouTube on click.

Version 2.0 adds per-card before/after title text, call-to-action buttons, three layout presets, Gutenberg blocks, a Classic editor toolbar button, an Elementor widget, full caching of titles and thumbnails, Schema.org video markup, and WP-CLI cache commands.

Features

• Single video cards via [youtube_link_card] shortcode
• Playlist grids via [youtube_playlist] shortcode (requires YouTube Data API key)
• Channel subscribe banner via [youtube_channel_banner] shortcode
• Embed hijack — automatically replaces existing YouTube embeds sitewide with link cards
• Gutenberg blocks — three dynamic blocks with live preview in the editor
• Classic editor toolbar button — opens a modal to build any of the three shortcodes
• Elementor widgets — three native Elementor widgets with full control panels
• Cached data — video titles, resolved thumbnails, playlists, and channel data all cached as transients
• Schema.org VideoObject markup for SEO rich results
• Layouts — default, compact, and minimal presets
• Before/after title text and CTA button with customizable colors

Installation

1. Upload the youtube-link-card folder to /wp-content/plugins/
2. Activate through the Plugins menu
