What You Need to Know
How YouTubers use Bluesky to drive views
The practical workflow for most creators: upload to YouTube, copy the link, and post it as a skeet.
Bluesky automatically generates a link preview with your video thumbnail.
Some creators pair this with a short text hook — the premise of the video, a question, or the key takeaway — to give Bluesky followers a reason to click.
Automating this with Make (Make.com) or IFTTT means every new YouTube upload triggers a Bluesky post with the thumbnail and link, no manual posting required.
Making your YouTube promotion land on Bluesky
Bluesky's crowd skews toward tech, journalism, and open-web advocates — different from a typical YouTube audience.
Write your skeet like a recommendation, not a channel plug.
Lead with the insight or the story, not 'new video out now.' The 300-character limit forces a tight hook; use it.
If your video covers a topic that resonates with the decentralized web or creator independence angle, lean into that framing.
A good skeet about a YouTube video can outperform a direct link with no context.
