Publer‘s auto-posting queue doesn’t work like a simple calendar. When you schedule posts across multiple social accounts for the same time slot, the platform uses a priority system to decide what publishes first—and if you don’t configure it correctly, your most important content can get stuck behind low-priority filler.
This matters when you’re juggling LinkedIn, Twitter, Instagram, and Facebook from a single dashboard. Each network has different API rate limits and posting windows. Understanding how Publer‘s queue prioritizes posts means the difference between coordinated launches and staggered, inconsistent publishing.
How the Priority Queue Actually Works
When you schedule multiple posts for the same timestamp, Publer doesn’t publish them simultaneously. It queues them according to three factors: account priority, post type, and API availability.
Account priority is the setting most operators miss. In your workspace settings, each connected social account has a priority value from 1 to 10. When two posts compete for the same slot, Publer publishes the higher-priority account first. Default priority is 5 for all accounts, which means new users get effectively random ordering.
Post type matters because different formats take different amounts of time to process. A text-only tweet publishes in under a second. A carousel post with eight images to Instagram takes 15–30 seconds because Publer has to upload media, wait for Instagram’s processing, then attach metadata. If you schedule both at 9:00 AM, the tweet goes live at 9:00:02 and the carousel lands closer to 9:00:35.
API availability is the wildcard. LinkedIn’s API occasionally throttles requests during peak hours (weekday mornings in US time zones). Facebook’s API can reject posts if your page has recent policy warnings. When Publer hits a rate limit or error, it pauses that account’s queue for 60 seconds and moves to the next priority account. Your post still publishes—it’s just late.
When to Adjust Priority Settings
Most solo operators should set LinkedIn to priority 8 or 9, Twitter to 7, and Instagram to 6. LinkedIn drives the most referral traffic for B2B content businesses, so it should publish first when time slots overlap. Twitter comes next because it’s time-sensitive; a tweet posted 45 seconds late misses the algorithmic window for early engagement. Instagram posts have longer shelf lives and benefit less from split-second timing.
If you’re running coordinated launches—a new course, a product drop, a newsletter issue—set all accounts to the same priority and stagger your scheduled times by two minutes. This forces sequential publishing and prevents API collisions. Schedule LinkedIn for 9:00 AM, Twitter for 9:02 AM, Instagram for 9:04 AM. You’ll see consistent publish times and avoid the queue lottery.
For daily content that isn’t launch-critical, leave priorities at default and use Publer’s “optimal timing” suggestion feature. It analyzes your audience activity and shifts posts into lower-traffic API windows, which reduces queue conflicts organically.
The Non-Obvious Tip: Use Priority Slots for Backup Accounts
Here’s what most people miss: you can connect duplicate accounts with different priority levels to create a fallback system. Connect your primary Twitter account at priority 8, then connect a secondary Twitter account (a brand backup or personal account) at priority 3.
Schedule the same post to both accounts. If your primary account hits a rate limit, suspension, or API error, Publer skips it and publishes to the backup account automatically. You don’t lose the time slot, and your content still goes live. This setup is especially useful for affiliate promotions or time-sensitive announcements where missing a window costs real money.
The trade-off: duplicate posts count against your Publer plan limits. The $12/month plan includes 50 scheduled posts across all accounts. If you’re doubling up for redundancy, you hit that cap faster. Upgrade to the $29/month tier for 300 posts, or reserve backup posting for high-value content only.
What Breaks and How to Fix It
Publer’s queue log lives under Analytics > Post History. If a post doesn’t publish on time, the log shows the delay reason: API error, media processing timeout, or account priority conflict. Check this weekly, especially if you’re managing client accounts or running paid campaigns.
The most common failure mode: Instagram carousel posts scheduled during API maintenance windows (usually Sunday mornings, 2–4 AM Pacific). Instagram’s API goes read-only during maintenance, and Publer can’t upload media. Your post fails silently unless you enable push notifications for publishing errors. Turn those on in Settings > Notifications > Publishing Alerts.
If you’re publishing to Facebook Pages, verify your page token hasn’t expired. Facebook tokens reset every 60 days, and Publer doesn’t always surface the error clearly. You’ll see posts stuck in “Pending” status in the queue, but the error log just says “Authentication failed.” Reconnect your Facebook account in Settings > Social Accounts > Facebook > Reconnect, and past posts will retry automatically.
