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.

Using the Shortcode

<pre><code>[subscribe_button_bar]

This uses your global plugin settings. You can override any setting per-use with optional attributes:
<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 channel=”@yourchannel” theme=”dark” text=”Subscribe for weekly videos”]
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 <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.

<h3>Arbitrary section</h3>

MailerLite – Signup forms (official)


	I got errors on activation and errors on trying to create a form, which I reported in the WordPress support forum. No response after over a month.
	The widget quit working, as I also described in the support request. 
	The link for where to get the API key, doesn't go to the place to get an API key. It's apparently trying to do a search of your help system, but the search fails, so basically it's just a link to the help system.
	When designing a form in the plugin:
	The label for the firstname field is "Name". So you have "Name" and "Last Name".
	There's no way to customize the field labels.
	There's no way to specify that we want a checkbox field for the user to select groups.
	There's no way to specify which fields are required vs. optional.
	It asks which groups as the first step before creating the form, when that could just be part of editing the form, so that screen is unnecessary.
	The default form description is "Just simple MailerLite form!". This is a poor default both because it's ungrammatical, and because nobody would want this to appear above their form.
	The default success message is "Thank you for sign up!" which is ungrammatical.
	There's no option for a consent checkbox as required by GDPR.


There's a lot wrong and a lot missing

This is a good plugin to add a for fairly quick and easy. If you are trying to do anything more, you will run out of luck fast. There are no settings or useful code hooks (actions or filters) for customizing redirect to landing page or other useful tricks with forms. 

Good but only for a very basic integration

I remained unable to use this plugin and related service due to errors on both and no one replies to the support questions.

Not recommended at all.

Poorly developed and no support.


The plugin does not work correctly with the new block based checkout. There are some issues regarding this from mora than 3 months with no resolution 😕 


No support for block based checkout

Add newsletter signup forms to your WordPress site. Subscribers will be saved directly to your MailerLite account. Super easy to set up!
