OAuth Channels
The widest caption limit, and the most forgiving scheduling window.
Facebook Pages still reach the largest broad-interest audience of any channel, and the 63,206-character caption limit makes it the one place a full article reads naturally. Sosial publishes to your Page on schedule.
Connect Facebook
Facebook connects with your Facebook login, then you pick the Pages to add. Sosial publishes as the Page, using the Page's own token.
- Open Channels and select Facebook → Connect.
- Sign in to Facebook and approve the Pages you manage.
- Back in Sosial, pick the Pages to add.
You need a role on the Page that allows posting content. If a Page is missing, ask a Page admin to give you one. If you manage many Pages and some don't fit in the list, connect them one at a time.
Limits
| Limit | Value |
|---|---|
| Caption limit | 63,206 characters |
| Media | Photo, video, or a link preview |
| Best length | 40–80 words for engagement, longer for storytelling |
| Peak times | Weekday mornings and early afternoon |
The composer checks these as you type, so a post that's too long for Facebook is flagged before it's scheduled.
What works on Facebook
- Longer storytelling posts
- Community questions
- Event and launch announcements
Tips
Use the first two lines as a hook
Facebook truncates after roughly 250 characters on mobile. Earn the "See more" tap.
Ask one specific question
A concrete question ("which of these two covers works better?") gets far more comments than "thoughts?".
Post native media, not a bare link
Native images and video out-reach link posts. Put the link in the first comment if you need the click.
Avoid
- Cross-posting an X-length post that reads as an afterthought.
- Engagement-bait phrasing that the algorithm suppresses.
- Posting a link with no context. Facebook down-ranks it.
