What is a social media scheduler?
Also called social media scheduling tool, post scheduler.
A social media scheduler is a tool that publishes posts to your social accounts at a date and time you choose, so you can prepare posts in advance instead of posting live.
Why it matters
Scheduling lets you batch a week of posts in one sitting and post at the times your audience is online, even when you're busy. Most platforms have a basic scheduler built in; separate tools add one calendar for several platforms.
Example
On Sunday evening you write five posts, set them for 9 a.m. Monday to Friday, and the scheduler publishes each one on time.
