What is a social media posting queue?
SHORT ANSWER
A posting queue is a set of weekly time slots you define once. New posts drop into the next open slot automatically, so you do not pick a date and time for every post.
When it helps
Queues suit steady posting rhythms, such as three feed posts a week per client. You can still schedule a specific post at an exact time.

Set slots per account, then add posts to the queue from the composer.
