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.

<pre><code>[subscribe_button_bar]

<pre><code>[subscribe_button_bar channel="@yourchannel" text="Subscribe for weekly videos!" theme="dark" layout="full" count="hidden" bg_color="#1a1a1a" text_color="#ffffff"]

 [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 <code>/subscribe</code>). The block renders server-side so it always reflects your current settings.
The block sidebar includes:
<ul>
<li>Video URL — paste a YouTube video URL or Shorts URL (e.g. <code>youtube.com/watch?v=...</code> or <code>youtube.com/shorts/...</code>). The block will embed the video and place the subscribe bar directly below it. Leave empty to show only the subscribe bar.</li>
<li>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.</li>
<li>Custom Text Override — override the button label text for this block only. Leave empty to use your global custom text.</li>
</ul>
Entering Your YouTube Channel
The plugin accepts any of the following formats in the settings page and in the <code>channel</code> shortcode attribute:
<ul>
<li>Channel ID: <code>UCxxxxxxxxxxxxxxxxxxxxxx</code></li>
<li>@Handle: <code>@yourchannel</code></li>
<li>Channel URL: <code>https://www.youtube.com/channel/UCxxxxxxxxxxxxxxxxxxxxxx</code></li>
<li>Handle URL: <code>https://www.youtube.com/@yourchannel</code></li>
<li>Legacy user URL: <code>https://www.youtube.com/user/yourchannel</code></li>
<li>Custom URL: <code>https://www.youtube.com/c/yourchannel</code></li>
</ul>
The plugin parses the input automatically — no need to extract the channel ID manually.
Getting Started:
<ol>
<li>Install and activate the plugin via the WordPress dashboard.</li>
<li>Navigate to Settings > Subscribe Button Bar.</li>
<li>Enter your YouTube channel — paste your Channel ID, @handle, or any YouTube channel URL.</li>
<li>Configure your desired appearance settings and save.</li>
<li>Embed any YouTube video in a post/page and the subscribe bar will appear automatically. Or use <code>[subscribe_button_bar]</code> to place it anywhere.</li>
</ol>
<h3>External Services</h3>
This plugin uses the YouTube Subscribe Button API provided by Google’s Platform Library (<code>https://apis.google.com/js/platform.js</code>). This script is loaded on pages where the subscribe bar is displayed and may send the visitor’s IP address and user agent to Google.
