How to Set Up YouTube to LinkedIn Automation
Connect YouTube and LinkedIn
Link both social accounts to PostOnce using secure OAuth authorization.
YouTube uses standard OAuth and LinkedIn requires standard authorization. Both connect in seconds.
Configure your automation rules
Choose to crosspost everything or filter by hashtags, content type, or custom rules.
Since YouTube allows longer captions (5,000 chars) than LinkedIn (3,000 chars), you may want to review caption truncation settings.
Post on YouTube as usual
Create content on YouTube and PostOnce handles LinkedIn distribution.
Both platforms use 16:9 format, so your content transfers seamlessly.
Flexible Automation Options
Control exactly how your YouTube content gets distributed to LinkedIn with powerful automation rules.
Post Everything
Every YouTube post automatically goes to LinkedIn
Filter by Hashtag
Use specific hashtags to control what gets crossposted to LinkedIn
Custom Rules
Set advanced filters based on your YouTube to LinkedIn workflow needs
Most creators use hashtag filtering to maintain control over their crossposting workflow. For instance, you might want all your YouTube tutorials to go to LinkedIn, but keep personal content separate. Simply add a specific hashtag like #autopost to your YouTube caption, and only those posts will be distributed.
If you want to repurpose content from YouTube to LinkedIn, you can also customize how captions, formats, and media are adapted for each platform's unique audience and requirements.
