Connect YouTube to LinkedIn

Before you start

• A YouTube channel. Any channel you can sign in to works, monetized or not.
• A LinkedIn account. Post Once posts to your personal profile, not a company Page.
• A Post Once account. The free plan includes 10 reposts, with no card needed.

How to connect YouTube to LinkedIn

1. Create a free account at app.postonce.com. After two short intro screens, Post Once asks where you post.

2. Under Where do you post first?, pick YouTube and press Continue.

   

3. Under Where else should it land?, pick LinkedIn. Add any other apps, or a backup, then press Continue.

4. On Connect your accounts., press Connect on the YouTube row. Sign in with the Google account that owns your channel and allow access.

   

5. Press Connect on the LinkedIn row. Sign in with LinkedIn and allow access.

6. When both rows say Connected, press Go to dashboard.

From then on, keep posting on YouTube as usual. Post Once checks it about every five minutes and reposts each new post to LinkedIn.

Already using Post Once?

If YouTube is already the source of your bridge, open Bridge and press Connect next to LinkedIn in the Destinations card, or press Add destination on the dashboard.

If your bridge reads from another account, add a second bridge with YouTube as its source from the bridge switcher. Free and Solo include 1 bridge, Studio 3 and Agency as many as you need. See bridges.

What each YouTube post becomes on LinkedIn

On YouTube	On LinkedIn
A Short	A video post.
A video over 3 minutes, or a landscape one	A video post, up to 30 minutes and 500 MB. Longer videos skip LinkedIn.

A skipped post shows the reason on your dashboard and still goes to your other destinations. See long videos for how Post Once tells short from long.

How your caption carries over

The video’s description becomes the caption. A video with no description uses its title instead. Private and unlisted videos are not picked up, and neither are community posts.

LinkedIn takes captions up to 3,000 characters, and hashtags in them become LinkedIn hashtags. Posts are public, on your personal profile.

Choose what goes to LinkedIn

On the Bridge page, the LinkedIn row has two settings.

• What to post has one switch here, Videos, since videos are all that go from YouTube to LinkedIn. Turning it off pauses LinkedIn.
• Rewrite caption changes the caption for LinkedIn only: Remove comment, DM and link in bio prompts, Remove hashtags and mentions, Rewrite with AI to suit LinkedIn, and Add your own text at the start or end. Each one is off until you turn it on.

Check that it works

Post something on YouTube as usual. Within about five minutes it shows up under Your posts on the dashboard (press Check now to look straight away), then goes to LinkedIn. Each post shows where it went, what was skipped and why.

If a repost fails, Post Once tries again up to 5 times over about half an hour. If it still fails, you get an email, and Retry sends it again to just the accounts it missed. See a post did not repost.

Only posts published after you connect are reposted on their own. Older ones are listed in Your posts, where you can send any of them by hand.
