Subscribe Button Bar for YouTube Embed Videos

Subscribe Button Bar for YouTube Embed Videos is a robust WordPress plugin designed to seamlessly integrate YouTube subscription functionality into your website. It automatically detects YouTube videos within your content and strategically places a customizable YouTube subscribe button bar directly beneath them.

This plugin serves as an effective video marketing tool, creating a sleek, non-intrusive call to action that encourages viewers to subscribe to your channel immediately. Whether you aim to increase YouTube subscribers, improve viewer engagement, or ensure a consistent user experience with a fully responsive design, Subscribe Button Bar provides the professional features necessary for channel growth.

Key Features:

• Intelligent Auto-Detection: Automatically identifies YouTube iframes within your posts and pages and injects the subscribe bar — no manual setup per post needed.
• Shortcode Support: Place the subscribe bar anywhere — pages without videos, sidebars, landing pages — using a simple shortcode.
• Gutenberg Block: A native block editor block lets you drop the subscribe bar exactly where you want it in the visual editor.
• Flexible Channel Input: Enter your Channel ID, @handle, or paste any YouTube channel URL — the plugin figures out the rest.
• Fully Customizable: Tailor colors, text, theme, and layout to match your brand.
• Responsive Design: Looks great on desktops, tablets, and mobile phones.
• Performance Optimized: Lightweight with no jQuery dependency on the frontend.
• MutationObserver Support: Catches YouTube videos added dynamically (AJAX pagination, lazy loading).

Customization Options:

1. Enable/Disable Toggle: Master switch to turn the subscribe bar on or off globally.
2. YouTube Channel: Enter your Channel ID, @handle, or any YouTube channel URL.
3. Theme Selection: Choose between Default (light) and Dark themes.
4. Subscriber Count: Show or hide the subscriber count on the button.
5. Layout Options: Default (icon + « Subscribe » text) or Full (channel avatar + channel name).
6. Custom Text: Add personalized text that appears before the button.
7. Background Color: Customize the bar’s background color.
8. Text Color: Customize the text color.
9. Post Type Control: Restrict the bar to specific post types (posts, pages, custom post types).
10. Per-Post Exclusion: Exclude specific posts or pages by ID.

This uses your global plugin settings. You can override any setting per-use with optional attributes:

Embed a video with a subscribe bar below it: [subscribe_button_bar url= »https://www.youtube.com/watch?v=dQw4w9WgXcQ »]

Embed a YouTube Short with a subscribe bar below it: [subscribe_button_bar url= »https://www.youtube.com/shorts/VIDEO_ID »]

Full layout, no subscriber count: [subscribe_button_bar layout= »full » count= »hidden »]

Using the Gutenberg Block

In the block editor, search for « Subscribe Button Bar » in the block inserter (or type /subscribe). The block renders server-side so it always reflects your current settings.

The block sidebar includes:

• Video URL — paste a YouTube video URL or Shorts URL (e.g. youtube.com/watch?v=... or youtube.com/shorts/...). The block will embed the video and place the subscribe bar directly below it. Leave empty to show only the subscribe bar.
• Channel Override — enter a Channel ID, @handle, or YouTube channel URL to use a different channel on this specific page. Leave empty to use your global settings.
• Custom Text Override — override the button label text for this block only. Leave empty to use your global custom text.

Entering Your YouTube Channel

The plugin accepts any of the following formats in the settings page and in the channel shortcode attribute:

• Channel ID: UCxxxxxxxxxxxxxxxxxxxxxx
• @Handle: @yourchannel
• Channel URL: https://www.youtube.com/channel/UCxxxxxxxxxxxxxxxxxxxxxx
• Handle URL: https://www.youtube.com/@yourchannel
• Legacy user URL: https://www.youtube.com/user/yourchannel
• Custom URL: https://www.youtube.com/c/yourchannel

The plugin parses the input automatically — no need to extract the channel ID manually.

Getting Started:

1. Install and activate the plugin via the WordPress dashboard.
2. Navigate to Settings > Subscribe Button Bar.
3. Enter your YouTube channel — paste your Channel ID, @handle, or any YouTube channel URL.
4. Configure your desired appearance settings and save.
5. Embed any YouTube video in a post/page and the subscribe bar will appear automatically. Or use [subscribe_button_bar] to place it anywhere.
