How to set your posting times
Set your posting times in the social set's Scheduling section: tick the days for each time under Posting slots, and changes save as you make them.
Slots run on the set's own time zone, and changing them never moves a post that's already scheduled.
Once the set has saved its slots, Next slot in the Schedule popover puts a Buzz into the first free one.
Set the slots
1. Press the set's name in the top bar, then Manage social sets, and pick the set.
2. Open Scheduling.
3. Under Posting slots, tick the days for each time in the grid. Press the × at the end of a row to remove that time.
4. To add a time, type it in the field under the grid and press Add a time.
To start from the suggested times, press Prefill. It ticks exactly those cells, and Undo puts your week back.
Note: A set that never saved its own slots shows Suggested for this set. Until you press Keep these times or change a cell, the set has no posting queue, so Next slot waits.
Where the suggested times come from
Once a set has 10 posts with likes or comments, the grid marks Your best times: the weekday and hour slots where its own posts earned the most engagement. Until then it shows Starter times, the hours each platform in the set is usually busiest, and the line above the grid says how many of your posts count so far.
Post into a slot
1. In the composer, press Schedule.
2. Press Next slot for the next free slot, or Pick slot to choose one of the set's slots in the next 2 weeks.
3. Press Schedule Buzz.
A Buzz on Next slot holds that slot, so no other post can take it, and it goes out on the slot's exact minute. With Natural posting time on, any other Buzz goes out up to 4 minutes either side of the time you picked.
Questions
Does changing my slots move posts I already scheduled?
No. Scheduled posts keep their time. New slots apply to the next Buzz you schedule.
Why can't I press Next slot?
The set hasn't saved its own posting slots yet. Open the set's Scheduling, tick your slots or press Keep these times, and Next slot works from then on.
Which time zone are my slots in?
The set's own. Each social set has a time zone in its Scheduling section, detected from your browser when the set was made.
