A posting queue replaces picking a date for every post. You set slots once (say Monday, Wednesday and Friday at 9:00) and add posts to the queue as they are ready. Each one goes out at the next free slot, so the account stays regular even when posts are written in batches.
Queues suit evergreen content: tips, articles, product photos, anything that doesn’t need a precise day. Posts tied to a date (a launch, an event, a sale) are better scheduled for that exact time, outside the queue.
