To add a YouTube subscribe button below a video in WordPress, use the Video (UB) block in Ultimate Blocks with Ultimate Blocks Pro. Embed a YouTube video, then turn on Show Subscribe Button in the Channel Settings panel. The block shows the channel’s profile picture, its name and a Subscribe button under the video. The Video (UB) block is free; the subscribe button is a Pro feature.
What you need #
- The free Ultimate Blocks plugin.
- Ultimate Blocks Pro, installed and activated alongside the free plugin.
- The link to a public YouTube video from the channel you want people to subscribe to.
How to add a YouTube subscribe button #
- Open the post or page in the WordPress block editor.
- Click +, search for Video (UB) and click the block to add it.
- In the Select Video Source placeholder, click Insert from URL, paste the YouTube video link and confirm. Normal watch links, short youtu.be links and Shorts links all work.
- With the block selected, open the Channel Settings panel in the Settings tab.
- Turn on Show Subscribe Button. The channel details appear under the video in the editor.
- Click Update or Publish.
How the channel is chosen #
You don’t type a channel name or ID. When you paste a YouTube link, the Video (UB) block looks up that video on YouTube and saves the channel that published it. The subscribe button always points to that channel.
- To promote your own channel, embed a video from your own channel.
- If you embed someone else’s video, the button asks visitors to subscribe to their channel, not yours.
- If you replace the video with one from a different channel, the button updates to the new channel.
What visitors see #
Under the video, visitors see the channel’s profile picture and name on one side and a Subscribe button with the YouTube icon on the other. Clicking the button opens the channel on YouTube with the subscribe confirmation prompt, so subscribing takes one more click.
Tip: Put your best video at the top of a tutorial or review post and turn on the subscribe button there. Readers who enjoy the video can subscribe without searching for your channel.
Common problems #
- I don’t see the Channel Settings panel: it shows only for YouTube videos, and only after the video is added. Uploaded videos, Vimeo and Dailymotion videos do not have a subscribe button. Also make sure Ultimate Blocks Pro is active and licensed.
- The channel name or picture is missing: the details come from YouTube while you edit. Check that the video is public, then remove the link and paste it again, and update the post.
- The button points to the wrong channel: the button uses the channel of the embedded video. Embed a video from the channel you want.
Other video settings you may want #
The Video (UB) block also has free settings such as Autoplay, Loop, Mute on page load, Show player controls, Allow custom start time and Use a custom thumbnail. See the Video (UB) block doc for all options.
